EDITORIAL
A progressive paradigm quick recap of the previous Editorial should put things in perspective here. In the last edition, this page highlighted the remarkable rise of the Asia-Pacific moulded plastics market, which is set to have the largest share of the world market and is forecast to grow at a significant pace through 2017. Primarily driven by strong domestic demand of the burgeoning economies of India and China, this is a crucial milestone to conquer.
A
Continuing this surging trend, India is set to expand its share of global polymer pie. As per a recent report by GlobalData, the country, currently the third largest consumer of polymers (after China and the US), accounted for 5.7 per cent of the global polymer market in 2011. It also states that the best is yet to come and quite rightly so. Given the tremendous prospects across various end-use sectors, such as packaging, food processing, automotive, infrastructure, healthcare, logistics and plasticulture, this observation seems fairly feasible. While the per capita consumption of polymers in India has risen from mere 1 kg in 1980 to 7.4 kg in 2010, we are still way below the global average and vis-à-vis enormous untapped potential. As per this report, the polymer products output in 2011 was 7.38 Million Metric Tonne Per Annum (MTPA), and this will grow at a Compounded Annual Growth Rate (CAGR) of 9.4 per cent to reach 11.57 MTPA by 2016. Further, most capacity additions in recent years have focussed on commodity polymers such as PE, PP, PVC, PET and SBR, which constitute more than 90 per cent of output. This study has also confirmed that polymer demand in India has surpassed the nation’s Gross Domestic Product (GDP) growth. During 2000-11, while India’s GDP rose at a CAGR of 7.6 per cent, polymer consumption across all segments surged at a CAGR of 9.1 per cent.

That said, a take on the exports front only adds to the need for a 360o perspective of the readers. And, there is good news! According to the report, the export value of processed plastics has doubled in the past five years, from $ 1.1 billion in 2006 to an estimated $ 2.3 billion in 2011. As more investments pour into plastics processing, the need of the hour is to not only have a visionary strategy towards India becoming a self-sustaining polymer superpower, but also initiating time-bound action thereof.

Bimodal HDPE for demanding blown film applications
SABIC has launched a family of bimodal High-Density Polyethylene (HDPE) for production of highquality thin blown film. The standard grade is HDPE FI0644, and a higher density grade with greater flow is HDPE FI1157. Both grades have high molecular weight and a broad molecular weight distribution. These characteristics translate into a good processability, which helps minimise disruptions during film production combined with good mechanical properties in the blown film. The low gel levels lead to consistent film production and a smooth film surface. Film makers can achieve acceptable gauge tolerances with adequate stiffness and strength at low thicknesses. Both grades can be processed at temperatures 10 per cent lower than common HDPE grades. Krzysztof Rozensal, PE Technical Marketing Engineer, SABIC, said, “The balanced properties of the grades are key to attaining a consistent, reliable and efficient film production process. Particularly, FI1157 can be processed at high speed, while maintaining robust bubble stability, maximising film output and minimising energy consumption.” Typical applications for FI1157 are production of lamination films, release films, inliners, labels and artificial paper. SABIC FI0644 is designed for applications requiring extra strength, such as heavy-duty bags, inliners, meat bags, grocery sacks and carrier bags.

Clariant solves liquid colour problems for polymers
Continuous screen changers to increase plant productivity
KREYENBORG GmbH has increased plant productivity in blown film extrusion through the use of continuous screen changers of type K-SWE. For an absolutely smooth and reliable filter change during operation, the screen changers are provided with a separate control. The retrofit should eliminate production line shutdowns during filter change and improve the filtration result, aiming at an increase in plant availability & productivity. The technology used in blown film plants almost exclusively includes simple, discontinuous screen changer systems that necessitate shutting down of the line for filter change. These are known as slide plate filtration systems. The screen changer is a modern filtration system that enables exchange of the mesh without interrupting the production. Thus, the system can continue running while soiled filter elements are replaced or filtration fineness for different production batches is changed. The operator benefits from the new filtration technique, as the number of necessary start-up processes is reduced to a minimum and production of rejects or start-up losses due to filter changes are reduced significantly. The result is an increased production capacity with improved filtration performance, which is reflected in the quality of the film produced.

What are your views about the polymer industry in India today?
Which other verticals have shown growth?
Overall, the polymer industry in India is performing well with high growth. However, in the last six months, we have seen a slight slowdown in the industry as a whole. Hence, many expansion plans have been stalled for a while, but growth is still there with a lot of potential for capacity expansion. People today demand technically superior products as many multinational companies have set up facilities in India, and this has allowed the industry to have access to global quality. Plastics processors are demanding raw materials used in the West, so we have to source our materials from companies that meet such specifications.
Many areas of the plastics industry have witnessed change in the last two years. One industry that has seen a downfall has been the shopping bag industry, which many governments have banned or are in the process of banning. Consequently, a new market has emerged with a product known as non-woven polypropylene fabric which is used to make shopping bags that look and feel like cloth. Since it is much thicker, it can be reused owing to its durability & easily recyclability. Many developments are happening in the compounding field, with new compounds and properties entering the market.
How is India poised as a hub for the masterbatch industry?
The perception about plastics is a key challenge for the industry. The Government’s attitude towards plastic bags has resulted in a lot of negative sentiments among manufacturers. Also, there are no clear guidelines for biodegradable plastics and how they can be implemented on a larger scale. Thus, if a manufacturer is focussed on the film industry, he would be affected with the ban on plastics imposed by many states. Sourcing raw materials has always been a challenge in our industry. The most widely used raw material is polyethylene and polypropylene, the majority of which we source locally with little imports. Even for imports, there is a long waiting period as our ports are not in a good shape. With regard to competition from China, we offer customised products to our customers. The cost and reliability factor associated with products from China is suspected by almost all processors who prefer domestic suppliers because of a wide range of advantages that we offer.
Masterbatches are an important component of the polymer industry and customisation is high in this sector. Many manufacturers offer customised products as per their customers’ requirements. By successfully implementing these standards, processors can tackle international competition as geographical proximity is an important factor for procuring raw materials. The supply and availability of material is there in the market, so growth can be witnessed. Further growth will occur because Indian polymer manufacturers are building capacities near their plants, especially in the North. This region will witness considerable development for the polymer industry.
What is the export scenario for Alok Masterbatches? We export to over 22 countries including regions like Europe, South America, South East Asia and the Middle East. There are large and small players who export masterbatches, with trading houses also participating in it. We export almost 25 per cent of our total product basket. This is because of high domestic demand and large number of plastic processors entering the market.
What are the challenges facing Indian masterbatch industry?
What Research and Development (R&D) initiatives have you undertaken? We invest a lot in R&D and also introduce new products catering to new segments of the market. In the last one year, we have introduced three new series of products,
which are targeted at fresh clients or clients who do not have such a product offering in India. For the agriculture sector, we have an entire range of products under the brand name AgriTEK. These products are not currently available in India. Other producers were offering piecemeal, where customers had to buy one product from one manufacturer and go to another manufacturer for their other requirements. People were buying polymer separately and pigments or masterbatches separately, which they had to compound in their factory and then use them. We offer a pre-compounded, pre-pulverised product so that our customers can concentrate only on moulding their products and leave the compounding to us.
What is the current growth trajectory for the industry? The entry of new players in the last five years has seen competition cropping up in the industry. Consolidation is bound to happen. There are producers focussing on single-purpose masterbatches for a definite purpose and focussed customers. This is good, but considering the unpredictability of the market, such an approach might not remain profitable in the long run. However, consolidation will happen faster only if we get the required Government support in terms of infrastructure and ease of implementation.
Where do you see the masterbatch industry in future? The rate of innovations witnessed by the masterbatch industry is commendable, but needs support from the Government to implement international policies & prices. Also, the increase in applications of polymers has resulted in more R&D by manufacturers, thereby increasing global competence. However, the Indian masterbatch industry has shown enthusiasm towards adopting latest technologies and exposure to international standards and quality, and this has ensured that plastics find more and more areas of application, which was earlier the forte of metal and wood.

he blow moulding industry is growing in the country due to wide applications, particularly in the pharma and cosmetics industry, which depend heavily on blow moulded products.

price of IBMs is quite high, the final product is of superior quality. This technology is generally preferred when volumes are low and the manufacturer operates on a smaller capacity. However, for larger components an extrusion blow moulding machine would be required.
Significant cost advantages Blow moulding has visible cost advantages as it is a process that deals with a hollow product. The parison has limited wall thickness, which is determined by the type of product to be manufactured. Tej Ram Singhal, Director, Suraj Plastic Industries, says, “The thickness depends on the applications according to which costs will be determined. Thus, volumes can be increased based on the applications and, costs can be kept low as per requirements. Also, blow moulding is cheaper than injection or extrusion moulding, as the price of machines is lower.� Another advantage is product flexibility that can be done with minimal investment; whereas in case of injection moulding, heavy expenses have to be incurred for the same.
Blow moulding innovations
Latest technology innovations The latest development is Fast in Fast Out (FIFO) technology, which is a form of accumulator-type blow moulding. An extruder is one of the primary components in blow moulding and with this new process, the time taken by the raw material as it enters the parison is faster and the entire process of blowing the material as per the desired shape is carried out faster. However, if there is considerable difference in the thickness along the shape of the product, a technology called parison programmer is used. “In case of a blow moulded bottle, the bottom is the thickest, the middle portion is thinner and the neck region is thick. To maintain this design element, we use parison programmer. The goal of the blow moulding process is to obtain a product whose parison is not too thin, otherwise, the container will break under strain,” advises Singhal. Thick sections are a waste of material and money. Hence, a well-defined thickness profile must be obtained at the end of the process. Product innovations as well as new developments in blow moulding machinery will bring in more new players into this business, thus contributing to the growth of Indian industry. Neeraj Garg, Partner, Suruchi Industries, says, “Among the new products, which an entrepreneur should look at, are multilayer polyethylene blow moulded bottles for milk packaging. Also, multilayer bottles for food packaging (cold filled) based on Low-Density Polyethylene (LDPE) or High-Density Polyethylene (HDPE) will make blow moulding industry more versatile.” Multilayer PE bottles made of unbreakable plastics help in handling the packaged contents at various stages.
Product versatility A spectrum of applications ranging from low-capacity blow moulded bottles such as pharmaceutical bottles to highcapacity products for chemicals, has helped entrepreneurs to fetch higher value additions for low-capacity bottles
and higher volumes of business for high-capacity drums. These blow moulded containers, HDPE carboys and HDPE jerry cans ensure safe delivery of pharmaceuticals & chemicals, thereby offering high impact resistance and less breakage. “Safe delivery is needed for packaging of chemicals and pharmaceuticals, as they may be hazardous and need to be packed in chemically resistant packaging that ensures safety during transportation and handling. Thus, blow moulded HDPE products become a need for packaging,” adds Singhal. Flexibility of blow moulding process as well as the machinery helps entrepreneurs produce more number of products with more number of moulds on the same machinery leading to a higher product mix, and thus a higher net profitability. New product development helps entrepreneurs bring in more business. The consistent rise in metal prices has witnessed a steady decline in the use of metal packaging, and this has resulted in plastics being the most preferred material for packaging. “The packaging industry is of the opinion that packaging materials made of tin should be replaced with blow moulded plastics. This is because tin, aluminium and other similar metals are not only more expensive, but also in short supply,” believes Garg.
The thickness depends on the applications according to which costs will be determined. Thus, volumes can be increased based on the applications and, costs can be kept low as per requirements. Also, blow moulding is cheaper than injection or extrusion moulding, as the price of machines is lower. Tej Ram Singhal Director, Suraj Plastic Industries
Challenges faced The industry does not have the right tooling components to work with besides the dearth of quality mould makers and designers. For instance, the automotive industry requires intricate detailing, which cannot be provided by blow moulding due to lack of precision and availability of technology. Overall, the blow moulding industry in India has the advantage of being cost-effective and can be customised according to application. If the right tooling technology is implemented, blow moulded products from India will have global competence.

SPECIAL FOCUS: Rapid prototyping
The last decade witnessed the rise of rapid tooling as a viable alternative to the otherwise complex traditional machining methods for blow moulding.

Reducing cycle time, enhancing productivity
T
he economics of manufacturing becoming tighter and rising production costs due to demanding applications have prompted manufacturers to move towards technology that delivers better accuracy, greater cost efficiency and maximum flexibility. Recent times have seen several advancements in Rapid Prototyping (RP) technology as it forays into the blow moulding industry in India. Globally, the technology has been widely used to manufacture prototypes and short-run production moulds for blow moulded parts. Some of these processes are Fused-Deposition Modeling (FDM), Three-Dimensional (3D) printing and Stereolithography (SL) to lower product-development time and cost. The success of these technologies can be attributed to newer RP materials that are more durable, have a higher strength, better heat resistance and finer finish due to a more sophisticated production process. 42
The advent of these technologies in India has been slow and utilisation is at a nascent stage. This can be attributed to valid concerns about accuracy, strength and mould finish.
Gaining market foothold The advancements in RP/Rapid Tooling (RT) materials have allowed processors and Original Equipment Manufacturers (OEMs) in India to re-think their stance on RT, specifically for blow moulding and thermoforming applications. Apparently, RT has made gains in these processes because they are viewed as being less taxing on RT materials in terms of impact, pressure and heat. The 3D modeling techniques have been of special interest in creating rapid prototypes. For blow moulding, there has been an interest in developing moulds for prototype Polyethylene Terephthalate (PET) bottles for water and Carbonated Soft Drinks (CSD), which are major segments of this industry. FDM is predominantly used

for RP. With the exception of venting and shut-offs, the FDM tool’s design is similar to a machined version. Since the FDM cavity has lower porosity, the air trapped between the moulded plastics and tool surface is vented through the body of the tool. To minimise flash, a sloped, raised rib is added around the contour of the cavity. With FDM tooling, the lead time for prototype parts can be reduced drastically. Also, the cost is one-third to half of

that of a prototype aluminium tool. It is recommended that Polycarbonate (PC) material be used for blow moulding tools, as it can withstand short-run production of numerous High-Density Polyethylene (HDPE), PET, Polyvinyl Chloride (PVC), Polystyrene (PS) or PC. “Multiple iterations of possible blow moulding prototype solutions can be created and tested in a fraction of the time required to develop physical prototypes. Also, using stress analysis, photo-realistic rendering, motion studies and other cutting-edge 3D modeling tools, the prototypes can be optimised for durability, appearance & performance. The use of innovative technology is helping engineers to quickly arrive at the most durable, attractive and cost-effective prototyping solution,� says Sambit Pradhan, ManagerBusiness Development-Asia Pacific, Geometric Ltd. The prototypes are fully functional and almost as good as the finished applications would be, and this is a remarkable achievement within a short span of time. The finished prototype could also give clients a chance to hold, for example, a blow moulded bottle, one that they can touch and squeeze to get a better sense of how the finished product will be like.
Analysing RP methods
In applications with demanding requirements, Polyphenylsulfone (PPSF) and PC are processes offering a higher Glass Transition (Tg) than ABS. This depends on the tool and part material. For instance, FDM tool life can be in the range of 100-1,000 parts. Nilkant Raut
44
One of the most economical methods to produce RT for thermoforming is 3D printing. 3D printers find broad usage by manufacturers who want a one-day mould turnaround and short-run production up to 500 parts. 3D printing allows the manufacturer to have complete control over machinations of building a fully functioning prototype within a relatively short time. High-performance SL resins are boosting the penetration of RT into thermoforming and blow moulding. The epoxy/acrylate is heavily filled with silica nanoparticles and boasts of a Heat Distortion Temperature (HDT) of 260°C/500°F. It also provides superior sidewall quality, with better detailed resolution than other RP materials and processes.

“In applications with demanding requirements, Polyphenylsulfone (PPSF) and PC are processes offering a higher Glass Transition (Tg) than ABS. This depends on the tool and part material. For instance, FDM tool life can be in the range of 100-1,000 parts. With the exception of venting through the porosity of the tool (as in blow moulding) and addition of a perimeter rib, the tool is designed like any typical machined mould. Cooling channels may be constructed in the FDM tool, but a simpler and faster way will be to use a standard mounting plate with cooling lines,� asserts Nilkant Raut, Director, Raut Engineering Pvt Ltd.
Rising on global stage RP is a non-linear approach that allows for more flexibility in the instruction of design and can catch problems in the initial development stages. It reduces development time and costs. This yields a viable method of production, further reducing lead times, initial tooling costs and increasing the ability to better scrutinise various designs in the Research and Development (R&D) stage itself. It eliminates the need for endless revisions with prototypes, paving the way for innovation. To acquire prominence on the global stage, India must adopt technologies to further augment its core competitiveness. This will help create better and varied functional designs allowing the manufacturer a great degree of flexibility that conventional methods do not offer. The aim of the RP process is to develop an efficient, reliable and flexible fabrication technique for the blow moulding process. This process would then completely revolutionise the aspect of manufacturing. Using conventional methods, such as machining, engineers are limited in the ability to design by the drastic length of time required to prototype an idea. Prototyping takes a week or more just to build an idea. With the RP system, even an inexperienced operator can learn about the machines and build the prototype in less than three days.

SPECIAL FOCUS: Engineered blow moulding
Controlling input
ensuring quality
The overall efficiency of any blow moulding machine is not determined by its output alone, but also by the input it requires. The amount of raw material and time required for maintenance are important concerns. In this regard, engineered blow moulding offers solutions to various industrial applications without compromising on quality and output time. Vijay Vora

ntelligent machinery with closed production cycles ensure that there are no material leftovers. A positive knock-on effect of this is environment safety. Thus, efficiency meets responsibility.
Engineered blow moulding Engineered blow moulding is a versatile process for fabricating parts. Effective designs for blow moulding of parts leverage on the inherent advantages of the process, eg, a hollow aspect of design, strength-toweight structural integrity and suitability for large shapes. The designer must also work within the process limitations and decide on the extent to which the material can be stretched and complexity/detail can be reproduced. Also, the part length limitation by material melt strength and
the design must make economic sense compared to other processes & materials.
Design–processing relationship Engineered blow moulding forms parts by blowing a hollow parison outward to conform to the mould shape. Inherent to this process is stretching of the thermoplastic resin material, thinning the walls. Forcing the material to stretch too much may make it impossible to control wall section thickness or rupture/fracture the parison. The extent of stretching in blow moulding of the parison is determined by the degree of asymmetry in the basic shape and by amount of complexity and localised detail in the part. The designer can evaluate the suitability of a part for blow moulding by examining blow ratio conditions in the part. Blow ratio describes a relationship between depth and width, and relates to the
amount of material stretching that occurs. Each case must be considered separately, and the basic shape be examined for tackling blow ratio problems. The extent of sideways parison travel should be less than parison length. One way to address this is to ensure proper orientation of the part in the tool. A review of complex sections and part details can help here. Decreasing the width or increasing the depth will require the material to stretch more to force through opening. Filling this detail will yield gains, particularly at the corners. Also, it is important to minimise depth and maximise width.
Multiple blow ratios A part with complex design may have numerous blow ratio conditions. In some cases, two separate conditions may prevail in a single area of detail. These conditions should be studied early on to determine whether various details can be reproduced in moulding.
Designing basic shapes Common blow moulded shapes present standard situations.

and assess the mouldability of details. Building the structure into parts, keeping the design simple and checking economies of scale against other approaches will ensure efficiency of the moulding system.
Maximising process efficiency In order to avoid blow ratio problems, one should take full advantage of inherent process strengths, develop a basic shape that can be moulded
Vijay Vora is Director of Roshma Pet Plast Pvt Ltd. Email: vijay@ roshmapetplast.com
S-shapes Limited mouldability Orient to minimise parison travel Material thinning at edges and corners Hollow shapes are inherently stronger because of their structure. This existing structure can be enhanced without changing the material in three basic ways: Increase nominal wall thickness of part Balance section modulus through ribbing a single wall Develop compression tacking patterns Sidewalls are forced together by the closing action of the mould to form a single wall. This creates local areas with locally thick walls. It also develops localised beam sections that are more resistant to bending, tension and torsion. The direct-acting hydraulic cylinder applies the clamping force centrally on the clamping platens, and the movement of the two clamping platens is precisely synchronised. Large available spaces around the mould area for specialised mould functions and below the clamping platens for installation of optional parison manipulation equipment, as needed for production of industrial parts & large complex containers, are an integral part of the machine design. As per the application, accumulator heads or continuous extrusion heads are used, the latter for co-extrusion of up to six layers. In continuous extrusion mode, the parison is either inserted in the mould with a parison feeder or a shuttling clamping unit receives the parison from the die head.

“Customers today demand for more application-specific solutions” …observes Nikunj Shah, Managing Director, Jagmohan Pla-Mach Pvt Ltd, in an exclusive interaction with Lionel Alva. He elucidates various aspects of the Indian blow moulding industry and how the technological paradigms for the Indian market are decidedly different from that of the rest of the world. of precision. Also, wastage and labour costs are reduced. Processing parameters determine whether 3D blow moulding should be used in a specific process.
Are technological trends in India for extrusion blow moulding comparable with those in Europe?
What are the current trends in the blow moulding industry in India?
What innovations are the most significant in the Indian context?
The exponential growth of the packaging industry has placed it among the fastest growing industries in India. Transformation has entered plastics due to its robustness, reliability and long life of applications as well as competitive pricing. The industry is extremely demanding and several new avenues for plastics applications are being explored, especially in blow moulding for thermoplastics. As a process, blow moulding has become faster and more refined. With rising competition, blow moulding offers several advantages as it is a relatively inexpensive and energy-efficient manufacturing process. With sequential coextrusion, products that previously had to be assembled from several individual components (pipe sections, bellows, clips, clamps, etc) can be made as one component in a single step.
We believe in innovating reliably. The solutions that we offer focus on standardisation and our emphasis is more on further simplifying machinery usage, thereby achieving utmost customer satisfaction. Customers today are more demanding and require application-specific solutions while having room for flexibility. In the current context, it is difficult for most manufacturers to use expensive, cutting-edge technology. Our machines are tailor-made for the Indian market and offer a fine balance between technological sophistication and accessibility. And that is our USP.

What is the significance of 3D blow moulding in India? In India, Three-Dimensional (3D) blow moulding has not yet found extensive usage. But, it has certain inherent advantages such as better control of materials to a point
Modern Plastics & Polymers | September 2012
The economics of manufacturing for the Indian market are demanding. Several machines available abroad are state-of-the-art while being expensive. The machines we offer are based on market demands and customer specifications. Foreign machine manufacturers are the best in the world, but their machines are costly, thus resulting in a delayed breakeven point for squaring on the capex investment by the customer. We compare our machines to customers’ needs and offer the best possible solution that fits their requirements and is not expensive. Thus, we offer the best possible technology at the best possible price.
What are the challenges faced by Indian blow moulding industry? The Indian blow moulding industry has rapidly grown in volumes and areas of application, and is quite competitive. Customers keenly assess the changing dynamics of the market, while scrutinising the competition. Hence, customers consider alternative sources if they offer better raw material and labour costs since the running production cost impinge on their final margins. As a result, they invest in blow moulding projects, which is not their parent business. Nevertheless, manufacturers are satisfied with the quality of raw materials available and the overall dynamics of the manufacturing process. Email: lionel.alva@network18publishing.com

Indian blow moulding industry leverage on applications beyond packaging? Can
Latest innovations in plastics blow moulding have prompted manufacturers to leverage opportunities beyond packaging. Lionel Alva assesses the changing dynamics of the blow moulding business in the Indian plastics industry and its competitiveness on the global platform. Dhimant Shah Managing Director, Gujarat Export Ventures
W hile conventionally, blow moulding is primarily used for bottling solutions, this approach has changed in recent times. The Indian blow moulding industry has witnessed exponential growth in volumes and of application areas. The unfavourable economic conditions have also helped the industry considering the relatively low economies of operation. The market for blow moulded packaging is stabilising after rapid growth. Developmental prospects are changing and both polymer suppliers & converters have an opportunity to spur a new phase. Manufacturers are enhancing flexibility that will allow them to explore possible applications beyond packaging. These include nonpackaging uses – ranging from toys to medical devices. New material options include biopolymers, eg, Polylactic Acid (PLA), as well as traditional resins are increasingly being used in high-performance applications.
Santosh Sawant Business Head, Blenzor (India)
Erosion of traditional formats, namely, steel and fibreboard drums, development of permeation barrier & antistatic properties to enable plastics to compete better against steel and the intense competition are driving cost reduction programmes focussing on light weighting. The industry must adapt to the changing demands of the industry, with the leading suppliers of blow moulded drums & intermediate bulk containers evolving to support global procurement. The impact of tightening environmental legislation will promote global standardisation, and open opportunities for value added packaging concepts. As the market develops beyond price competition and users evaluate the total cost of container ownership, participants will re-define their businesses. This has prompted manufacturers using the blow moulding process to explore the tremendous opportunity for applications beyond plastics. Also, Indian manufacturers are favourably placed to capitalise on these evolving business prospects.
Shyam R Mange Head-Business Strategy, Jagmohan Pla-Mach Pvt Ltd
Today, especially on foreign shores, major breakthroughs have happened in key applications such as automobile, road barriers and toys. Developments are happening in the realm of thermoplastic polymers using blow moulding technologies. Indian manufacturers are manufacturing polyethylene terephthalate bottles for high-end applications, which will be considered as a one-stop solution to all their clients’ needs. Thus, the changing market conditions have impelled manufacturers to look at solutions beyond packaging. This is an outcome of the natural course of business towards consolidating market position and building a viable long-term strategy. Technologies such as three-dimensional blow moulding, rapid tooling and prototyping has played a large role in enhancing the future prospects. India must take on a much bigger role in the blow moulding industry to accommodate the changing business dynamics.
Editorial take: Email: lionel.alva@network18publishing.com Blow moulding manufacturers seem to be satisfied with the rapid growth in the packaging industry. However, with the dynamics of the blow moulding industry changing rapidly, manufacturers must work towards positioning themselves as one-stop platforms to meet customer needs in an increasingly competitive market scenario. 50

FACILIT Y VISIT: Pragati Polyplast India Pvt Ltd
Progressive approach to excellence Blow moulding has come a long way in India in terms of volumes and product portfolio. Among the pioneers of this industry in South India, Pragati Polyplast India Pvt Ltd has emerged as a key player in the phama & bulk drug packaging segment. Annabel Dsouza assesses the ideas and innovations that have enabled this company to make its mark in the blow moulding industry.
P
lastics has played a vital role in the growth and vitality of the Indian manufacturing industry. From packaging to agriculture and automobiles to electronics, plastics has revolutionised leading applications owing to its functionality, economics, aesthetics and reliability. Enabling this rapid surge in plastics application is the blow moulding process, which has expedited its availability for high-quality, low-cost, large-volume plastics containers. Among the leading manufacturers of blow moulded plastics in South India, Pragati Polyplast India Pvt Ltd offers a range of industrial packaging solutions such as drums/ containers and multilayer sheets. Satish Sanghi, Managing Director, Pragati Polyplast India Pvt Ltd, says, “The blow
moulding industry in India is growing due to increasing demand from the bulk drug and pharma sector. Apart from these, there are a lot of blow moulded plastic products such as road dividers, cold storage boxes, petrol tanks, pallets and ice-boxes. Having been in this industry since 17 years, we try to employ our expertise and economies-of-scale to provide value-added products to our customers and the industry at large.�
Manufacturing mantra Incorporated in 1993, Pragati Polyplast was among the first companies to cater to packaging requirements of the growing bulk drug and chemical industries of Andhra Pradesh. With container volumes ranging from 100 ml to 220 litre, the Pragati Group is one of the few manufacturers in India to offer such a wide range of products with varied capacities and applications. Based out of Hyderabad, the company began with a single blow moulding machine with a capacity of 30 tonne. Today, Pragati operates at a capacity of 600 tonne per month. Sanghi states, “We spotted a crucial trend in the blow moulding industry, ie, the growing demand for second hand barrels weighing 9-10 kg. These were used for water storage and repeated use of containers resulted in contents being exposed to dirt and chemicals.

INSIGHT & OUTLOOK: Plastics in home applications
Low-cost solutions for the
HOMEMAKER Engineering plastics has entered our homes like no other material, owing to features such as lightweight, low cost and resistance to heat and corrosion. Engineering plastics is currently the most preferred material for manufacturing products for home applications. Avani Jain gauges the significance of engineering plastics in home applications and the benefits they offer.
T
oday, most of the things around us, at home or work, which form a part of our daily life, are made of plastics. Plastics has become a virtually indispensible material. Uday Shah, Director, Vishva Exim Pvt Ltd, notes, “Earlier, as far as the usage of plastics in home applications were concerned, these were used only to make buckets, mugs, tanks, etc. But today, these are used in a variety of applications including furniture, home appliances like can openers, food processors, microwave ovens, mixers, coffee makers, etc. Even refrigerators use special plastic foams for insulation purposes, while the interior is made from plastics that are durable and easy to clean.” In fact, our day starts with the use of plastics in one form or the other. For most people, a typical day starts with

showering with their favorite shampoo, using an antiperspirant, checking daily emails while sipping a cup of coffee or favourite energy drink and packing lunch in the most attractive plastic containers. In short, plastics has become an essential part of our life and the most important material used for making various household products.
Role of engineering plastics The usage of engineering plastics is increasing in home applications as these are lighter in weight and attractive in appearance. Also, engineering plastics are a low-cost solution as compared to the traditional materials. Amit Mahant, Director, PK Plastic International Pvt Ltd, says, “Household articles are frequently subjected to high mechanical and thermal stress. Plastics that come in contact
Modern Plastics & Polymers | September 2012
with food must also comply with the international regulations. Thus, the usage of engineering plastics is imperative.” The key benefits of engineering plastics are cost-effectiveness, as these have lower manufacturing cost, corrosion/chemical resistance, lightweight (lower density), excellent surface finish (no secondary operations required), colourability (by addition of pigments/dyes), are decorative, paintable, flexible and soft. Engineering plastics have various properties that make them useful in home applications, such as lower density, thus reducing the weight of home appliances for lightweight production. Engineering plastics also offer good impact resistance, satisfactory hand feeling and excellent resistance to wear, vibration, sound absorption and good insulation to heat & electricity. These have a good processability,
Plastics in home applications
ease-of-forming, simplifying the processing of components with complex shapes and forming complicated products at one time for efficient batch production in a cost-effective manner. If calculated by unit volume, the production cost of plastic part is only one-tenth of that of non-ferrous metal. Engineering plastics enable flexible designing of products such as home appliances and furniture. These offer strong resistance to chemical substances such as acid, alkali and salt; thus, partial damage to plastic materials may not cause corrosion as in metal materials. Other properties of engineering plastics, which make them useful in home applications, include mechanical strength, rigidity, flame retardancy, specific strength & stiffness and durability. Thermoplastics (TPs) account for about 90 per cent of plastic materials used in home appliances and the remaining are thermosets. Most TPs are commodity plastics, eg, Polypropylene (PP), Polystyrene (PS), Polyvinyl Chloride (PVC) and Polyethylene (PE). The engineering plastics used in home applications are Acrylonitrile Butadiene Styrene (ABS), Polycarbonate (PC), Polyetheretherketone (PEEK) and Polybutylene Terephthalate (PBT).
it is light in weight, it can be easily transported anywhere and also helps in saving the transportation cost.” Moreover, engineering plastics do not rust or corrode like metal or decompose like wood when in contact with water. Thus, engineering plastics continue to replace metal in many areas of the consumer goods industry as these offer advantages such as weight reduction, low thermal conductivity, functional integration and greater design freedom. It also adds value for the manufacturer and end users as it is more cost competitive. And with a shelflife of more than 10 years, the weighing scale tilts more towards plastics than towards conventional materials. Mahant notes, “The most popular reasons for switching to engineering plastics in household applications include longer part life, elimination of lubrication, reduced wear on mating parts, less power needed to run the equipment, corrosion resistance and inertness.” Thus, plastics wins hands down when compared to conventional materials because they are high energy savers, soft, easy-to-maintain, fire-proof, moisture-resistant and cheap. In fact, it is these qualities that have made engineering plastics a popular material for manufacturing household products.
Engineering plastics versus conventional materials
Future scope
In keeping with the demand for metallic finishes in home appliances, polymer compounding innovations have led to replacing metal with plastics. Engineering plastics today are fast replacing conventional materials such as wood and metals. The main advantage of plastics over conventional materials such as wood and metals is that it is light, cheap and is suitable for outdoors application in furniture without damaging the piece. For example, plastic chairs are functional, durable, hold good for 7-8 years and are cheaper than wood. The chairs also come in bright, wooden finished colours today, thus enhancing the aesthetic value. Shah notes, “In terms of cost as well, plastic resin is cheaper than the traditional material like steel or iron. Further, since
Due to their multifaceted applications, plastics has become an indispensible fixature of modern life. As the aspirations of people soar, more goods in the home applications segment will be manufactured from engineering plastics. Thus, the rising purchasing power is clearly driving the demand for innovative, lightweight and low-cost solutions. With their high performance properties, engineering plastics have not only gained popularity in heavy-duty sectors including automotive, electrical & electronics, but are also in demand in daily life supplies. At present, in home applications in India, engineering plastics still have a low penetration as compared to other countries, thereby creating tremendous opportunities for growth.

INSIGHT & OUTLOOK: Non-hazardous home appliances
INVESTING IN HOUSEHOLD SAFETY Technological marvels, with safety and convenience factors, have facilitated increased utilisation of engineering plastics in home appliances. However, these appliances may still pose dangers to the homemaker. Avani Jain elucidates the use of halogen-free and fire-retardant plastics for making non-hazardous home appliances, thereby preserving homemaker’s safety. for the same. Engineering plastics also possesses excellent self-extinguishing properties.” Today, another trend observed is that the quality of appliances as against price sensitivity is gaining importance in India, with increasing consumer awareness for health and environment. This scenario has led to development of new products and innovations in the plastics houseware industry. One such innovation is the development of Halogen-Free Flame Retardant (HFFR) plastics and its increased usage in home appliances.

n today’s plastic age, plastics has become indispensable in almost every aspect of life. This holds true especially for the home appliance segment, where essential equipment, such as ovens, toasters, mixers, grinders, vacuum cleaners and washing machines, are increasingly being made from engineering plastics instead of sheetmetal and cast iron. This is because engineering plastics possess thermal, insulating properties that are ideal for use in house wiring and home appliances. Dr Harindu Vyas, President (Technical & Development), Signet Industries Ltd, notes, “Almost all parts of home 60
appliances, such as the food processing machine, dishwasher, refrigerator, washing machine, television set and microwave, make use of engineering plastics. For example, in food processing machines, the metal parts have poor chemical resistance. Hence, replacing it with engineering plastics increases the life of food processors & prevents the food from contamination of oxides, metal salts, etc. Further, due to light weight and excellent insulating properties, engineering plastics like Polyphenylene Oxide (PPO) is widely used for home electrical devices such as fuses and Miniature Circuit Breakers (MCBs), replacing heavy ceramics used
Modern Plastics & Polymers | September 2012
The home appliance industry has indeed come a long way, with today’s homemaker demanding appliances that are appealing in design, have superior mechanical strength combined with light weight and adequate safety features. M M Biswal, Business Head- Polymers, Loxim Industries Ltd, says, “Keeping in mind the consumer’s increased level of awareness and rising demand for safer products, today, all white goods use engineering plastics, especially HFFR plastics. No health hazards are associated with the use of HFFR plastics, as it does not produce toxic fumes. Thus, HFFR plastics has replaced conventional materials like metal, glass, etc. As a result, the demand for HFFR plastics is increasing by 20-22 per cent every year.”

Low Smoke Zero Halogen (LSOH), Low Smoke and Fume (LSF) and HFFR are all terms associated with compounds that are used extensively in various home appliances. These compounds are generally based on polyethylene or co-polymers of polyethylene with the addition of mineral fillers to impart flame retardant properties. Dr Vyas avers, “Flame-retardant is an additional property that can be incorporated into the plastics by adding flame-retarding agents. These agents reduce the flammability or delay combustion. Flame-retarding agents consist of halogens, such as bromine, which function by forming a protective thick layer of carbon char. This char does not allow the fire to spread and prevents plastic surface from burning further. Halogen flame-retarding agents cause environmental pollution and human respiratory disorders. In contrast, HFFR plastics contains nitrogen, inorganic and phosphorous as its components and does not cause much harm.� He adds, “HFFR plastics can help in developing non-hazardous home appliances as it produces low smoke, which permits the individual to evacuate the area quickly, and causes less soot damage to electronic components in the area around fire. Also, as it does not release halogen gas in the atmosphere, it causes no damage to the human respiratory system, if inhaled.�
Innovations making headway Today, quality-conscious companies and customers are moving towards eco-friendly products. Biswal notes, “Previously, brominated flame retardant (BFR) plastics was developed by the industry, but the focus today is on developing HFFR plastics. BFRs are organobromide compounds that have an inhibitory effect on the ignition of combustible organic materials. Among the commercialised chemical flameretardants, the brominated varieties were most widely used. However, the regulation and environmental impact is prompting the industry to move away
Modern Plastics & Polymers | September 2012
from BFRs. The current developments for application of flame retardants in engineering plastics are focussed on HFFR products.� Most HFFRs have an environmentfriendly profile, which means they pose no harm to the environment and do not bio-accumulate. In addition, these have a low toxicity profile and will eventually mineralise in nature. Biswal says, “The main reason for using HFFR plastics in home appliances is that they neither catch fire easily nor emit toxic fumes. HFFR plastics comply with Restriction of Hazardous Substances (ROHS) directives.�
Future prospects The home appliance industry in India is expected to grow by 11-12 per cent to reach ` 397 billion by 2013-2014. Expanding households, rising income levels and lower prices of home appliances in real terms are expected to make them affordable to a larger number of households. Further, since consumers are demanding high-quality products, the emphasis has shifted to quality rather than price, and this is a positive sign for the plastics industry. It is for the same reason that the demand for HFFR engineering plastics in home appliances, as compared to metal is increasing by the day. This is not the only reason for increase in demand for engineering plastics in home appliances but there are a number of factors. This demand will only increase in future as new developments surface the in the industry. Today, researchers are continuously working to upgrade engineering plastics with properties like environmental sustainability. Especially in the home application segment, a new kind of anti-bacterial plastic is being developed. This has the property of self-sterilisation by resisting the growth of bacteria on its surface and providing safety to human health. Thus, with the development of HFFR plastics and other innovations, engineering plastics will completely take over traditional materials in the home appliances segment.

INSIGHT & OUTLOOK: Inter face - Dr Premal Vashi
“Government and industry must come forth to build R&D infrastructureâ€? ‌suggests Dr Premal Vashi, Director-Engineering Plastics, Som Shiva (Impex) Ltd. In a conversation with Avani Jain, he underlines the growing demand for engineering plastics in home applications and the challenges faced by the industry. How is the demand for engineering plastics in home applications? India is fuelling the growth of Asian countries, and all home appliance manufacturers are focussing on Indian market to fulfil their needs. Home appliances require good mechanical properties and aesthetics such as a glossy outer surface. This is because home appliances are mainly for the consumer market and need to be more attractive. Thus, the recent trend is to use engineering plastics in home appliances for better look and performance. Engineering plastics such as polycarbonate, Acrylonitrile-Butadiene-Styrene (ABS), Styrene-Acrylonitrile (SAN) and acrylics are most common polymers that have replaced metal & other thermoset products in the home appliances segment. For example, earlier, mixer jar was made only from steel, but today, steel has been replaced by polycarbonate material. Even household electrical switches were earlier made from thermoset material, but a recent development is the usage of engineering plastics for modular switches concept. Also, earlier, Miniature Circuit Breaker (MCB) used in households was made from thermoset material, but it has now been replaced by Polybutylene Terephthalate (PBT) and Polyamide 6 material. 64
What properties of engineering plastics make them useful in home applications? Engineering plastics are versatile materials as they possess good mechanical, electrical and thermal properties. Thus, their usage in home appliances leads to product performance that is much better than conventional products. These also help in increasing product life, leading to higher productivity with lower production cost. As a result, the use of engineering plastics is increasing day by day due to their advantages such as better productivity, design flexibility, light weight as compared to conventional materials, good product performance and enhanced life span.
What are the recent research & development (R&D) initiatives of your company? At present, the company is focussing on the home appliances segment to replace metal parts with plastic compounds. We have introduced high-gloss material to replace ABS with commodity polymers to save cost, yet yielding similar performance. For example, iron skirt handle is now replaced by high-gloss material polypropylene.
Modern Plastics & Polymers | September 2012
What are the challenges and opportunities faced by the industry? Engineering plastics processors are facing tough times due to lack of Government support and industry-friendly policies. India is a growing market, but we do not have any manufacturing plant for engineering polymers, eg, polycarbonate, PBT, Polyamide 66, polyacetal, etc. We are mainly dependant on import substitute. Also, we do not have proper R&D infrastructure and manufacturing capacities to meet the growing demand. Thus, the Government and industry must come forth to build R&D infrastructure and indulge in superior product development.
What would be the future of engineering plastics in home application products? Although the consumption of engineering plastics in home application products is far less than countries such as the US, yet the demand is increasing gradually. In the US, the average consumption of engineering plastics is 20 kg per capita; however, in India, it is only about 4 kg per capita. Thus, there is a huge scope for growth. This shows that the overall consumption of engineering plastics will surge in future. Email: avani.jain@network18publishing.com
INSIGHT & OUTLOOK: Coining of plastic par ts
Designing the finer aspects Coining, also known as Injection Compression Moulding (ICM), is an advanced form of injection moulding used for making highquality plastic parts. Here is an overview of this technique used for making high-precision parts such as ophthalmic devices.
Y R Anand
M
any plastic parts such as thin-walled packaging items, optical parts, finely textured surfaces or parts with large surface areas need special alteration of an injection moulding process called ‘Coining’. This modification in technical terms is known as Injection Compression Moulding (ICM). The process is derived from the way metal coins are produced the world over. This occurs by squeezing a flat metal sheet between the die (with the indentation of the coin) at a high clamping force, thus altering the shape of the metal.
Understanding ICM An advanced form of injection moulding, ICM has benefits for both the process and quality of the part. As compared to conventional injection moulding process, a significant feature of ICM is that the mould cavity space can be automatically adjusted according to different requirements. For example, it can be injected into the cavity before the material is well oriented, part of the mould has closed and the cavity space is expanded to twice the wall thickness of the parts completed. 66
Advantages of plastic optical parts Courtesy: Arburg GmbH + Co
However, all advantages of ICM are counter-balanced by the fact that additional features are needed on the machine that and mould design becomes restricted with respect to part geometry. Mould must be designed to prevent the melt from escaping at the parting line Protrusions or undercuts against the direction of injection/compression are a problem The machine must be built in with an additional software/hardware feature to actuate both injection and movement of clamping unit
Principle of ICM As the injection process begins, the mould is usually not completely closed. Only after the cavity has been supplied with melt will the mould halves be closed completely. Consequently, less pressure is required to fill the cavity, thus reducing the pressure gradient during the filling phase. As the mould closes, uniform pressure is exerted over the entire cavity surface of the shrinking part, so that the pressure level in the cavity remains uniform.
Mould technology This refers to movement of axes of the

Enormous freedom in terms of design of optical functional surfaces Integration of multiple functional components Low material costs Low specific weight Economical production in a single processing step, while maintaining high quality Large quantities can be implemented with ease injection moulding machine. Main axes involve mould opening and closing, injection & dosing, while secondary axes have ejection, nozzle movement & core pulls. Main axis coining: The cavity volume is influenced by clamping unit movement. For instance, the cavity can be sealed by a vertical flush face. It is also possible to create a seal via an axially movable cavity ring or coining frame. This approach is suited for flat parts with uniform wall thickness. Undercuts or punctures perpendicular to the direction of coining present a problem. Even partial surfaces can be coined using the main axis. In such cases, mould concepts with cavity rings are utilised. When partial surfaces are coined via the main axis, the processing window is limited. Secondary axis coining: Here, the mould is completely closed and cavity volume is altered via moveable zones (eg, punches) within the cavity. Core

functions will control the punch hydraulically. The moulding machine’s ejector mechanism can also be utilised in the coining process. This process is suitable for partial surfaces, as any mould opening forces that do not act in un-coined areas are absorbed by the machine’s holding force. Coining via the clamping unit offers considerably higher force reserves as compared with punch coining in the mould. Moreover, the clamping unit’s measurement system provides better process monitoring than when core functions are utilised. This is because the quality achievable, in terms of process reproducibility, depends on reproducibility of axis movements.
Machine technology Clamping unit design: Every clamping unit design has its advantages for use in the coining process. Fully hydraulic clamping units enable coining paths corresponding to the clamping unit’s maximum traversing distance. These can apply maximum coining force at any point of travel, given an active counter force, which is usually equal to maximum clamping force. These clamping units are equipped with longitudinal measuring systems that exhibit a measurement resolution of 0.1 mm, ensuring a coining position precision in the order of one-tenth of a millimetre. Hence, the system is used mainly for longer coining paths of 1-10 mm. The achievable positioning accuracy is sufficient for such applications. Due to the toggle kinematics of toggletype electric clamping units, clamping force and traverse speed always depend on the opening stroke. Full clamping force is not achieved until the toggle is locked. Thus, high coining forces can be achieved only if the coining path is short. Some electrically driven machines must be equipped with powerful drive motors in order to provide adequate coining forces. Typical coining paths achievable by electrically driven clamping units lie in a range of 1 mm. Reaction 68
Merits Part quality No sink marks on the thicker wall sections at the end of flow path of the part For clear/transparent parts, the optical properties are greatly improved Shrinkage is compensated by compressing the melt
speed and coining speed are high, as time required for hydraulic pressure buildup is nil here. Reproducibility is higher than that with fully hydraulic designs, due to the use of longitudinally regulated drive systems.
Philosophy of the best design In optical component production, the drive systems do not exclude, but supplement each other, as required by the application. Formerly, most optical parts were made from glass, but today a vast majority of such parts are being produced by plastic materials and mostly by the injection moulding process. The major requirements for production of high-quality plastic optical parts are cleanliness and reproducibility. A majority of these parts have narrow tolerances in dimensions, which means that the in-process parameters such as temperature, machine movements and machine parameters require maximum process control. Many thick-walled optical components such as camera lenses and human lenses with large differences in wall thickness are common. These will invariably necessitate the use of injection compression moulding and, if possible, variotherm mould temperature control. For instance, moulding machines from Arburg of Lossburg, Germany, enable the user to program the required coining sequence freely and individually. The main and secondary axes can then be utilised in a single sequence. But, coining becomes universal when combined with force and speed regulated programming. This makes currently known and implemented special cases available to the user in a compact, logical and easily configured sequence control.

of ICM Process Provides better venting, thereby allowing easier filling of the mould Reduced material stress and shear Lesser clamping force required and uniformly acting holding pressure Reduction in holding pressure time, hence cycle time For thin-walled parts, flow distance/wall thickness ratio is reduced
Generally, injection moulding machines with high positioning accuracy and good reproducibility should only be used for injection coining. The coining technology must be selected on the basis of mould concept and configuration. Depending on the application, both hydraulic and electric machines can be used. An example of such a coining application in the ophthalmic devices industry is production of lowstress, true-to-form thick-walled blanks for eyeglass lenses that are coined sequentially via the main axis. A mould equipped with a coining frame is used, which is closed except for a defined gap. The screw supplies the melt at low pressure, thereby traveling to its forward stop. When the mould closes (coining), the melt spreads out into the cavity. The mould is equipped with rapidchange shaping inserts. Lens thickness can be set by varying the coining gap. This requires no simultaneous movements of the clamping unit and screw by the drive technology. Finally, companies need to decide during the product design stage about whether ICM will be significant qualitatively and/or economically. Equipping the machine with options to run ICM later on is easier than changing the philosophy of mould design.

For best-in-class performance Polyvinylidene Fluoride (PVDF) copolymer-based process aids are among the best in terms of key performance comparisons between the most popular selling grades in the market. Here are the results of a study comparing the performance of pure and synergist-containing fluoropolymer products. Viral Vora and Franรงois Beaume

luoropolymer and Fluoroelastomer Polymer Process Aids (PPAs) have for many years aided in extrusion. Polyvinylidene Fluoride (PVDF) copolymer-based PPAs excel in the elimination of melt fracture as well as pressure drop experienced during extrusion.

Masterbatch preparation: PPAcontaining masterbatches were formulated using 2 per cent of PPA in a Linear Low-Density Polyethylene (LLDPE) support resin with a Melt Index (MI) of 0.9 gm/10 min. The masterbatches were dry blended and extruded in a twin-screw co-rotating extruder. Each masterbatch was then dry-blended with a reference resin to get 200 parts per million (ppm) of PPA in the final resin called the formulated compound. The reference resin is a 70/30 blend of LLDPE with an MI of 0.9 gm/10 min and LDPE with an MI of 0.39 gm/10 min, containing no PPA.

Results Measurements were taken until the film showed no defects in the surface, and results prepared in graphs. Pressure drop progression was noted of several formulations at a final PPA concentration of 200 ppm on the flat die extruder. Four widely used competitive products and two PVDF copolymer-based compounds 5300 & 8600 were tested. The PVDF copolymer-based products exhibited the largest pressure drop in the range of 24-26 bar. The competitive products showed pressure drop of 15-23 bar, with only Competitive 1 being within 2 bar of the pressure drop showed by PVDF copolymer-based products. The increased pressure drop of PVDF copolymer-based compounds 5300 and 8600 should allow for higher increases in output using the same base PE resins & equipment. PVDF copolymer-based compounds 3121-50 and 2821 are fluoropolymers and are 100 per cent active. These do not contain partitioning agents like their fluoroelastomer counterparts, which contain 8-12 per cent of inactive ingredients. With pure fluoro products, all three products showed pressure drop of 18-20 bar, but the PVDF copolymer-based 2821 showed optimum result. Thus, the performance of PVDF copolymer-based PPA in pressure drop is as good as or better than popular products in the market. Mapping was done of PPA products with both pressure drop and time to eliminate melt fracture for synergist72

containing products. Not only PVDF copolymer-based products 5300 and 8600 have high pressure drop, but these also eliminated melt fracture within seven minute in this test on the flat die extruder. In both performance criteria, PVDF copolymer-based PPAs were among the best popular synergist product offerings. In the mapping done for pure PPA products, pressure drop for the products was similar, but the time to clear melt fracture was significantly different on the flat die extruder. PVDF copolymer-based 3121-50 cleared melt fracture in 7 minute, while other two products were clear at 11 and 12 minute. Both PVDF copolymerbased 3121-50 and the Competitive 5 are new-generation products targeted for high performance in systems with aggressive mixing. PVDF copolymerbased 2821 performs well in most systems but is optimised for more moderate mixing conditions.
Compaction of synergist products In products containing synergists, the synergist should be combined with the fluoropolymer or fluoroelastomer. Traditionally, this was done in a simple manner – as a dry blend of powders. A new process compacts the two components, not only offering a second product form for ease of handling, but also improving performance over dry blended products. Compaction is a more intimate mixing of the two components to provide a complete synergistic effect. A graph was drawn for different ratios of the synergist mixed with fluoropolymer. Some were combined by dry powder
Modern Plastics & Polymers | September 2012
blends, while others were compacted. As the synergist content increases, there is a clear benefit for product that is compacted in eliminating melt fracture more quickly. The compaction process allows products such as PVDF copolymer-based 5300 and 8600 to perform better than other similar dry-blended products.
Matter par excellence Both synergist-containing and pure fluoropolymer products are available that show favourable performance as compared to other popular fluoroelastomers. Thus, product optimisation and the new compaction process for synergistcontaining products aid manufacturing of best-in-class performance PPAs.

INSIGHT & OUTLOOK: Six leadership activities
Critical to climb the growth ladder
This article does not talk about time management, nor is it about work-life balance. It simply gives an outline of why and how leaders should plan their time and apportion it according to the varied needs of the business. This is a crucial focus area for the long-term growth of the business. M Hariharan or a leader to create and run an organisation, he must spend his time on things that are relevant for today and tomorrow. A leader has to focus on how time is spent on various aspects in his business life. The six activities that a leader needs to spend time on are: Daily fire fighting Daily routine Self-development Others’ development Daily improvement Dream for the future If the leader spends maximum time on ‘Daily fire fighting’, there will be little time left to focus on the remaining five activities. ‘Daily fire fighting’ cannot be avoided, but need to be minimised by focussing on the other five. Let us focus on each of these six activities.
F
Lack of skill and preparedness in the team (lack of others’ development) This leads to most leaders’ time being spent on wasteful activities. Although most individuals enjoy the thrills and crisis of ‘Daily fire fighting’.
Daily routine activities ‘Daily routine activity’ is defined as ‘any activity we perform, that is part of our day-to-day function emerging out of the system we have put in place’. This activity can minimise ‘Daily fire fighting’ to some extent. These activities over a period should be delegated to the team through ‘Others’ development’, so that the leader can find time for other three activities. These activities enable business as usual and are critical to ensure stability
in the organisation. But, these lack the fun of ‘Daily fire fighting’.
Self-development Personality development and personal development are not what can be classified as ‘Self-development’. These activities are important for an individual to develop himself; however, in the context of this topic, the definition of ‘Self-development’ can be expertise in the core skill, while also developing skills to understand other functions and ability to guide other functions’. This is a critical first condition for a good leader. For instance, Toyota calls this as ‘T’ Leader. The stem of ‘T’ is competence on specific function, while the horizontal line in ‘T’ is understanding and ability to guide other functions. Thus, a leader must find time for self-development.
Dream for future
Daily fire fighting ‘Daily fire fighting’ is defined as ‘any activity we perform, which crops up due to unplanned events happening, that the team depends on us to help them solve’. The more this activity, the less is the time available for other activities. The causes of this activity may be the following: Uncertain external factors (has to live with) Lack of planned routines and system that create most situations that are uncertain (reflection of not planning daily routine & delegation) Lack of self-discipline of the leader, creating uncertainty (lack of selfdevelopment) 74

Six leadership activities
Development of others can enable the leader to release his energy to look beyond the horizon of the current status. Others’ development Leaders cannot be trained; they have to be identified and nurtured. A good leader has to identify and nurture the future leaders. This is critical for minimising the time spent on ‘Daily fire fighting’ and for ensuring continuity at the top. This part of leadership is sacrificed at the altar of ‘Daily fire fighting’. More often, work is delegated on the basis of ‘who can accomplish it without any goofing up’. A good leader has to delegate with an intention to coach. This attitude towards delegation is important for developing others.
Daily improvement A good leader should always look for room for improvement. Improvement includes minimising the efforts in daily routine, improvement to minimise ‘Daily fire fighting’ and a strong focus on changing the current status with delta improvements. In a way, looking for daily improvement should be more like a daily routine. This stems from the strong belief that there is always scope for improvement. ‘Daily improvement’ focus must be an integral part of ‘Self-development’ and ‘Others’ development’.
Dream for future This is the most important role for a leader. A good leader focusses on all issues mentioned earlier, but a great leader focusses on this aspect as the most critical. A leader should have time to dream about the future. Development of others can enable the leader to release his energy to look beyond the horizon of the current status. He must unlearn his past success to dream for the future.
Moving up the ladder The more a leader moves towards the last requirement of ‘Dream for future’, the better it is for the organisation. For a leader to spend time on this, he must sacrifice his thrill of doing the ‘Daily fire fighting’. Moving up the ladder of leadership choices, he can lead the organisation to the next horizon.

INSIGHT & OUTLOOK: Capillar y rheology
Tool for determining complex material characteristics While carrying out high-pressure and high-speed techniques such as injection moulding of plastic resins, it is vital to know how the plastic melt behaves during processing. In this regard, a capillary rheometer is an important tool, as it tests the processing conditions and response of melt to applied force, measures viscosity characteristics and simulates the injection moulding process. Dr Anand Tadas
O
ne of the most common methods of shaping plastic resins is injection moulding. In this process, the plastic material is fed into a heated barrel, mixed and forced into a mould cavity where it cools and hardens to the configuration of the cavity. The source of problems in injection moulding of resins depends on diverse factors, such as the resin used, mould design, processing variables, polymerrelated deficiencies or problems and the processing equipment used. The viscosity of the melt, plasticising rate and melt temperature are some of the processing variables causing common problems in the processing of complex materials. Economics dictate some use of regrind by the processor with a common approach of ‘more is better’. Regrind and
virgin resin should be thoroughly blended to avoid melt flow inconsistencies and dimensional variations. It is useful to have information in advance with regard to the behaviour of a material during processing. In this context, capillary rheology, with its ability to simulate such processing proves to be a useful tool.
Case study: Injection moulding of metal-loaded polymers PVT properties investigation When samples are injection moulded, it is important to know the PVT properties of the melt, as some types of melt may be more compressible than others. A compressible melt is likely to require slightly more volume to fill the mould but can then bleed from the injection point after moulding, resulting in the unsightly die ‘drool’. Variations in melt compressibility can also cause parts that should have flat surface to be made as convex or concave surface. This, in turn, can cause problems during fitting of the parts. The Rosand Capillary Rheometer is able to measure the Pressure–Volume–Temperature (PVT) characteristics of compounds and predict their suitability for use, or help predict the optimum injection moulder settings. The density of the hot polymer melt can be used as an indication to processability
while formulating new injection moulding compounds. The rheometer can also measure the high shear rate viscosity characteristics and simulate the injection moulding process. It can directly measure extensional properties, which shows how a polymer behaves during processes such as blow moulding and fibre spinning. This test found that Sample A is less compressible than Sample B; hence, it needs less volume upon injection and is less likely to result in die drool after moulding. The compressibility of a melt is likely to be related to its filler content, the polymer chain structure, polymer’s molecular weight, molecular weight distribution and the test temperature. Further, Sample B will need a higher initial injection volume but a small withdrawal (slight negative pressure) to reduce the die drool. This reduction in pressure on the die contents while the article solidifies for a few seconds may also help reduce swell (causing convex surfaces). If the total weight of polymer in the barrel is measured (weight added initially – weight extruded during precompression and initial descent), the density of the melt can be calculated. A comparison of the initial density value (at maximum volume) and the end density value (minimum volume / maximum pressure) can show comparative data for compressibility. Density of melt = Weight of polymer /volume

Moulding test simulation In this test, the compounds are sheared at rates similar to those in injection moulding. If the sample is extremely shear thinning, the shear rate data can be corrected using Rabinowitsch, which uses the power law index (n) to adjust for non-Newtonian flow through the die.
Capillar y rheology
The high shear rate data indicates how easily the melt will fill small mould apertures and how accurate the detail definition will be. It also shows how quickly the overall process may be carried out (within the limitations of the injection moulder). If the melt viscosity is too low, bleeding between the two touching mould faces may also be a problem. Further, Sample A was found to have a lower viscosity at all measured shears, indicating that it will be easily moulded and fill the mould quickly.
Extensional viscosity determination In this test, the polymer melt is subjected to a table of shear rates giving equilibrium viscometry data at each step. P0 is often plotted as a useful comparison of extensional properties, but it is worth remembering that the P0 data also encompasses other properties such as vortex flow, acceleration and elastic response of the sample.

In this test, Sample A was found to have significantly high extensional viscosity. As extensional viscosity is the resistance of a material to extend, ie, squeeze itself through narrowing of the mould, this can also indicate the ability of the material to successfully reach extreme parts of the mould. Although there is a relationship between shear and extensional viscosity, for most practical purposes, extensional viscosity should be considered as an
The Rosand Capillary Rheometer can be used to identify high-quality polymer compounds.

AUTOMATION TRENDS: 3D blow moulding
Illustration: Chaitanya Dinesh Surpur
Seamless quality control through automated solutions The Three-Dimensional (3D) blow moulding technology has provided several advantages that are not inherent to the blow moulding process. Lionel Alva scrutinises various facets of the 3D technology and how it has affected the outlook towards blow moulding, while providing insights into online quality control solutions.
T
odayâ&#x20AC;&#x2122;s plastics industry has a high level of material development and technological integration. In particular, the blow moulding segment is driven to take advantage of material development and computer technology with microprocessors, the latter enabling process programming of machines & robots. The machine and mould builders are responding by developing robust sophisticated equipment. The recent years have seen numerous technologies considered as being change inducing or epoch making. Among these, ThreeDimensional (3D) blow moulding is significant, since it has advanced in terms of increased possibilities for process application.
Understanding 3D blow moulding Over the last few decades, computer simulation models have significantly contributed to a better understanding of blow moulding processes and are now 78
widely used for process optimisation. Computer simulation models help mitigate undesired variations in wall thickness and reduce weight while maintaining strength. These offer a good alternative for trial-and-error methods with expensive blow moulding equipment or complicated measurements during a moulding process, which occur faster in a closed construction. Also, simulations can be used for comparison with measurements. The blow moulding process begins with melting the plastic material and forming it into a preform. A preform is a tube-like plastic piece with a hole at one end through which compressed air can pass. The preform is clamped into a mould and air is pumped into it. The air pressure then pushes the plastic material out to match the mould. Once the plastic has cooled and hardened, the mould opens and the part is ejected. Various computational models have been developed for modeling the forming of blow moulded containers.
Modern Plastics & Polymers | September 2012
Quality control ensures smooth operation of a robust and computationally Illustration: Dinesh Surpur efficient model Chaitanya for industrial uses, which can accurately capture the stretch blow moulding process of polymer containers. The model takes as input information the preform shape, a uniform temperature distribution of the preform and a prescribed inlet air pressure. It computes the container shape, final wall thickness and the stress & thermal deformations that the polymer undergoes during the process. The model is applied to the stretch blow moulding of a two-dimensional axialsymmetrical Polyethylene Terephthalate (PET) bottle with a complex geometry.
Factors influencing quality control In PET bottles, four areas determine bottle development for quality control â&#x20AC;&#x201C; design, weight, process and laboratory tests. Design includes development and construction with state-of-the-art CAD programs, 3D prototyping methods, problem analysis and solutions based on

finite element analysis & sample bottles. Weight is based on preform design dependent on stretching ratio and lightweighting, based on technical & economical feasibility. Factors influencing the process are high speed, low blowing pressure, low heat energy and alternative materials like polylactide or polypropylene. These factors must be considered while designing online quality control solutions.
Quality control methodology â&#x20AC;&#x153;Considering the pressure on companies to be more competitive, it makes sense to opt for online quality control solutions for 3D-PET blow moulding instead of manual checking. Although online leak detection is now commonplace, many other tests can be performed. Most systems used by blow moulders work by pressurising the mould and monitoring the change in that pressure during the test time,â&#x20AC;? observes Dhiman Dodhia, Executive Director, Dodhia Techno Engineering Pvt Ltd. Other methods for maintaining machine availability at the highest level: Preform testing: Only perfect preforms with impeccable integrity guarantee precise heating and stretch blow moulding processes. The systems are usually video-supported. Bottle testing: Testing systems detecting non-axial, irregular bottles are installed upstream of the air conveying line or at the rotating wheel. Damaged bottles are eliminated.
Achieving process optimisation The dynamics of 3D blow moulding are complex and must be well understood before designing a quality control system. The QC personnel should be more involved in the selection of leak testing equipment, as these are used for validating the quality of the moulding produced. This will allow implementation of a highly optimised production process. Email: lionel.alva@network18publishing.com

ENERGY MANAGEMENT: High-speed precision equipment
Conserving energy, enhancing productivity The blow moulding process involves various complex stages of operations, coupled with high-speed precision moulding techniques. Moulders are increasingly opting for energy-efficient mechanisms that complement high productivity standards. Anwesh Koley analyses the challenges in achieving production efficiency in blow moulding process and the measures required to rectify them.
B
low moulding is a process of thermoplastic processing to create hollow plastic products using compressed air and reflects the shape of the blow mould cavity. During machine design, energy consumption is not a major factor; however, there are some possibilities to reduce the energy consumption in general hydraulic machines. Worldwide, blow moulding machines are being called upon to manufacture an increasingly complex array of industrial products. Ravi Kumar, Director, Shiv Pooja Plastics, says, “To offset rising production costs stemming from these demanding applications, manufacturers turn towards machines that can deliver higher accuracy, greater cost efficiency and maximum flexibility. In fact, it is necessary to deliver improved performance and reliability in blow moulding machine design.” For decades, companies have developed blow moulding technology to remain at the forefront of high-performance motion control technologies for hydraulic blow moulding machines, which reduce time and also result in increased energy savings through the moulding process.
Challenges for compressed air Rotary Reheat Stretch Blow Moulding (RSBM) machines from leading manufacturers across the globe provide challenges to the efficiency of compressed air systems. These challenges include significant pressure drops in the RSBM machine with large instantaneous air demand swings. Large horsepower sizes for individual compressors increase consumption of compressed air, and the use 80

of high historical pressure equipment also adds to the problem. Besides, a single facility may have multiple pressure requirements, which makes steady monitoring a tough task. Despite these challenges, it is possible to achieve 15 per cent energy savings on the supply side with another 15 per cent achievable by focussing on the pressure drops in the blow moulding machinery.
Pressure-drop situations Stabilising air pressure is a primary objective. Pressure fluctuations occur in most stretch machines and are significantly
Modern Plastics & Polymers | September 2012
lower than expected. Correcting this can lead to increased productivity and reduced air consumption. Rajesh Panchal, Director, Om Chamunda Enterprises, says, “Blow moulders must understand the air pressure requirements of their machines. For example, the blow process consumes about 60 per cent of the air. The remaining pneumatic applications, using 40 per cent of the air for control components and packaging or decorating, will typically require lower pressures. Manufacturers must install a dedicated piping system to blow air circuits.”

The next step is to modify the pneumatic circuits on the blow moulding machinery, which is typically sized, by the manufacturer, based on average air demand rather than peak air demand. The pneumatic circuit on moulding machines consists of solenoids, regulators and tubing, which when undersized, creates pressure drops during the blow cycle. The pressure drop is really a lag in the flow of compressed air, which slows inflation and subsequent cooling of the container. If sized appropriately to match peak air demand by examining Critical Velocity (CV) of components, moulders can minimise the pressure drop, increase productivity and reduce plant air pressure. In process industries, companies are taking most of the measures available to optimise their processes in order to gain on productivity and reduce waste. “As compressors are the largest motors among the auxiliaries, consuming large amounts of electric power, anything we can do to save its energy is our focus,” adds Kumar. By adding air recovery system on blow moulding machine, the used highpressure air can be recycled after blowing the containers, thereby reducing the energy consumption. When using the low-pressure air compressor with same specifications, this system would extend the rest time of the air compressor, reduce its energy consumption and extend the service life of the machine. Also, after adopting the air recovery system, the blow moulding machine can be equipped with a smaller low-pressure air compressor; this also decreases energy consumption, hence reducing the production costs.
Reducing energy consumption High-speed electric feeder solutions help machines consume up to 30 per cent less energy than competitive hydraulic machines. These produce higher quality, more repeatable parts today. End users are continually searching for an edge in product quality, from plastic bottles that utilise 30 per cent less material to complex package designs. If a processor has high-speed precision motion control, it would ensure uniform wall

thickness and guarantees that all parts meet quality specifications. The compact design of high-speed electric solutions help save valuable floor space, which means customers can increase the number of machines at work at any given time. “In order to ensure safe operations, built-in safety features including fail-safe and slow set-up mode help reduce unplanned downtime and foster operator safety,” adds Kumar. Today, blow moulding machines are used to make everything from vessels to toys to car gasoline tanks. To offset rising production costs from evermore demanding applications, customers need blow moulding machines of even higher accuracy, efficiency and flexibility. “In order to solve the challenge of accurate positioning under high-speed motion, it is important to ensure more accurate parison thickness control for highest product quality and lower production costs,” adds Panchal. A complete system of high-response servo valves, the machine controller and an advanced Man-Machine Interface (MMI) will help overcome technical challenges. Highly accurate multi-axial control system yields faster and more stable close & loop mould movement speed. The hardware/ software design of the machine controller should provide control of cover wall thickness, weight temperature, motion and other measured values. To address upgrading requirements, the controller must integrate intelligent temperature control, closed-loop motion control, a dedicated wall thickness control and a servo valve current drive. By focussing on specific requirements, high-speed blow moulding solution providers are able to provide high performance solutions that ensure energy savings at various stages during the moulding process. “Today, it is important to ensure commitments beyond initial collaboration to facilitate reliable and flexible products worldwide. For smooth functioning of a technology as well as timely delivery of the final product, service technicians worldwide are ensuring timely and precise repair of components,” concludes Panchal.

POLICIES & REGULATIONS: Anti-dumping duty
Revitalising industry prospects In recent years, the anti-dumping duty has caused a stir in the Indian industry owing to its effects on plastics consumption, manufacturing practices, quality standards and pricing pressures. Annabel Dsouza assesses both sides of this controversial debate and its implications on India’s surging plastics industry.
A
mong the most controversial issues to have plagued the plastics industry in emerging markets is the rampant import of materials and equipment from lowcost manufacturing countries. A strong player in the Asian market, India is firmly committed to the principle of free and fair trade among nations, which is the foundation for the multilateral trade order established by the World Trade Organization (WTO). While a giant step has been taken by India towards establishment of free-trade regime with the phasing out of Quantitative Restrictions on imports since 1991, there is also a need to ensure fair trade between developed and developing countries. Depending on the need, anti-dumping, anti-subsidy countervailing and safeguard measures have been invoked in the past. 84
Navin Trambadia, Proprietor, Global Technoplasts, avers, “All these measures are in the nature of trade remedies, which the domestic industry could take advantage of, subject to the fulfillment of essential conditions and criteria as mandated under law. In recent years, the Government has already established the requisite legal and institutional mechanism for administering these measures. However, various concepts and legal & operational aspects involved in these schemes need to be understood in the proper sense and in the right perspective.”
Implications on trade dynamics Dumping is said to have taken place when an exporter sells a product to India at a price less than that prevailing in its domestic market. However, the phenomenon of dumping per se is not
Modern Plastics & Polymers | September 2012
condemnable as it is recognised that producers sell their goods at different prices to different markets. Kamlesh Shah, Managing Partner, Devang Plastics, elaborates, “It is not unusual for prices to vary from time to time owing to supply and demand conditions. It is also recognised that price discrimination in the form of dumping is a common international commercial practice. It is also not uncommon that the export prices are lower than the domestic prices. Therefore, from the perspective of antidumping practices, there is nothing inherently illegal or immoral about the practice of dumping. However, where dumping causes or threatens to cause material injury to the Indian domestic industry, authorities initiate the necessary action for investigations and subsequent imposition of anti-dumping duties.”

Navin Trambadia Proprietor, Global Technoplasts
The Ministry of Commerce & Industry had imposed definitive anti-dumping duty on imports of certain plastics processing machines, particularly injection moulding machines from China. The levy was to come into force for five years from May 12, 2009, the date on which the provisional anti-dumping duty was imposed. The specified percentage is in the range of 60-174 per cent, depending on the producer. Based on a petition filed by a Chennai-based machinery manufacturer, the designated authority in the Commerce Ministry had, in 2008, initiated anti-dumping investigations on imports of plastics processing machines from China. The Revenue Department had specified that the anti-dumping duty would be a percentage of the Cost, Insurance and Freight (CIF) value of imports. However, blow moulding machines, vertical injection moulding machines, all-electric injection moulding machines, multicolour/multimould machinery were excluded from the levy.

86
The anti-dumping duty is slated to have a positive impact on technology innovations and quality standards of the Indian plastics industry. Trambadia adds, â&#x20AC;&#x153;With an increasing number of qualityconscious consumers, manufacturers in India are driven towards developing indigenous machinery solutions or sourcing technology solutions from European players. Although this imposes significant cost pressures on the domestic industry, it has a long-term benefit in terms of volume consumption with reliable material & equipment solutions.â&#x20AC;? The Indian industry must prove that dumped imports are causing or are threatening to cause material injury to the domestic industry. Material retardation to of an industry is also regarded as injury. The material injury or threat cannot be based on mere allegations. Sufficient evidence must be provided to support the contention of material injury. Injury analysis can broadly be divided in two major areas:
Modern Plastics & Polymers | September 2012
Volume effect: Authorities examine the volume of the dumped imports, including the extent to which there has been or is likely to be a significant increase in the volume of dumped imports, either in absolute terms or in relation to production or consumption in India, and its effect on the domestic industry. Price effect: The effect of the dumped imports on prices in the Indian market for like articles, including price undercutting, or the extent to which the dumped imports are causing price depression or preventing price increases for goods, which otherwise would have occurred. While plastics processing machinery manufacturers in India have since then seen favourable times, plastics processors are concerned that their margins will be hit by 20-25 per cent due to the anti-dumping duty on imports of certain plastics processing or injection moulding machines from China. Indian machines cost at least 25 per cent more than Chinese machines. While the price of machinery varies with size, quality and degree of automation, on an average, Chinese machines cost anywhere between ` 5 lakh and ` 10 crore. Machinery and moulds account for nearly 70 per cent of the cost of setting up a plastics processing business. Indian customs levied on Chinese imports of tariff margin amount will be based on final determination of the dumping case to make adjustments.
The way forward The anti-dumping duty still remains a controversial issue, but with the worldâ&#x20AC;&#x2122;s two largest developing economies engaging in imposing barriers in key matters such as imports, it might be a cause of concern in the years to come as both countries boast of a booming plastics industry. The All India Plastics Manufacturers Association statistics has shown that by 2012, India is expected to become the third largest plastics market in the world after the US and China. Hence, an economic deadlock between two such prosperous markets might not be in the best interests of the global market. Email: annabel.dsouza@network18publishing.com

STRATEGY: Industr y–academia collaboration
Cultivating skilled human capital Through the industry–academia collaboration approach, companies in the Indian plastics industry can deal with the challenge of shortage of skilled human capital and enhance their productivity & performance, thus accelerating economic growth. Avani Jain notes the benefits of investing in skilled human capital through industry–academia collaboration.
I
ndustry–academia collaboration offers several benefits to both parties involved. With regard to the plastics & polymers processing, the industry can reap a lot of benefits through such ollaboration. These include reduced costs, increase in knowledge, greater marketing power and availability of skilled human capital, which is the need of the hour for the industry. Tushar Parikh, Vice Chairman, Indian Plastics Institute (IPI)–Ahmedabad Chapter, notes, “Skilled manpower is the demand of every industry and plastics industry is no exception here. Today, companies are expanding and employing new technologies, thereby demanding skilled manpower. However, skilled manpower is a scarce resource. Investing in human capital is an important step. An effective way to achieve this is through industry–academia collaboration.” 90
He adds, “In the plastics industry, all production processes require skilled engineers and operators for highgrade machines. Also, the companies need efficient workforce for marketing. Through industry–academia collaboration, companies can actually train students to meet such requirements.” The Indian plastics and polymers industry can leverage the potential of institutes, namely, Central Institute of Plastics Engineering & Technology (CIPET) and Indian Plastics Institute (IPI), as a source of intellectual human capital. Dr Subhas Chandra Shit, Deputy Director, CIPET, Ahmedabad, advises, “Industry–academia collaboration is important for the growth of the plastics industry, and the industry must nurture young talent so that both parties can benefit in the long run. An institute, we are initiating collaboration with
Modern Plastics & Polymers | September 2012
companies, so the industry should also come forward.”
Role of the institutes The plastics institutes should send their researchers on deputation basis to industry to work in their laboratories to gain experience on new equipment & processes. Institutes should welcome technical staff f rom the industry to interact with their students, thereby fostering closer relationships and encourage industry-focussed collaborations, which can then be funded by industry with support from their own staff. Various plastics institutes have adopted steps to strengthen the industry–academia collaboration. Parikh avers, “The IPI acts as a link between the industry and the institute. We are involved in various activities; for

instance, we invite companies for campus placements and conduct workshops for students. Even technical experts are invited to deliver guest lectures on specialised subjects. We organise one technical seminar every year. Recently, IPI had organised a technical seminar on ‘Advancements in Flexible Packaging.’ In this seminar, industry experts made presentations on subjects related to the theme. Further, we send students to 3to 4-day workshops at any company’s facility to empower them with practical experience in addition to theoretical knowledge. Thus, such a step facilitates their learning process.” Today, institutes also provide on-thejob training to students. Dr Shit notes, “Our laboratory is well equipped with all instruments, so that students can learn how to operate machines along with the production process.” Thus, the institutes have a fundamental role to play in training manpower.

Many companies have embraced industry–academia collaboration to invest in skilled human capital. Recently, Solvay inaugurated its new Research, Development and Technology Centre at Savli, India. The Centre focusses mainly on the development of highperformance polymers, organic chemistry, nanocomposites and green chemistry. When fully operational, this centre will tap the country’s huge talent potential and carry out open innovation in collaboration with premier institutes in India. Thus, through such industry– academia collaboration, students will acquire the quality and skills required for this specific industry. This is just one type of collaboration and there are various ways through which industry–academia collaboration can be successful for the industry as well as students. The private sector needs to be open to collaborations with the plastics institute, as the industry gets immediate benefits in terms of more profits and trained manpower, while students get the benefit of seeing their ideas work and gain confidence. Through this, the institutes can also be assured of regular fund supply and required practical exposure.
Modern Plastics & Polymers | September 2012
Challenges posed Currently, two basic types of collaboration can be seen between industry and institutes. First, collaboration between companies and institutes for product or process research is imperative. Second, collaboration where companies bring in new technology and institute helps them to adapt to the local conditions. The first type is more frequently observed. However, both types of collaborations are not common in India. Parikh avers, “As against the universities in US, where R&D centres are established within the university and students get projects from the industry itself, the scenario in India differs. In India, institute campuses do not have R&D centres. This means no industry projects, and thereby no funds from the industry. Thus, steps should be taken in this regard.” Fu r t h e r, industr y–academia collaborations can be feasible, provided that clear areas of cooperation are worked out before starting projects. The key challenge is Government support and availability of funds for such initiatives. Although institutes are doing their best to train students, professional courses need support from the Government as well as the industry.
In a nutshell Industry–academia collaboration has been effective in many developed countries. Major global corporations have made it clear and some have even declared in their strategy that they are ready to invest in skilled human capital through academic collaboration. Thus, industry–academia synergy has a high probability of attaining success in India, as it is a major plastics and polymers hub. Moreover, the industry generally faces substantial shortage of research talent with the requisite skill set and experience in advanced analytical research, but this collaboration will help the industry in this aspect also. Thus, industry–academia collaboration can serve as a strategy for ensuring success and growth of India’s plastics & polymers industry through investment in skilled human capital.

TIPS & TRICKS: Plastics tooling solutions
STEPS TO
prolonged mould life Moulds for plastics processing can be expensive, so it is important that companies using these moulds protect their investment by regular preventive maintenance. Anwesh Koley looks into various measures that can help processors ensure a healthy mould life, resulting in seamless processing.
M
ould maintenance for plastics processing has assumed importance as it has a direct impact on the functioning of machines. However, companies are often tempted to
overlook this and wait until their mould breaks down or has a serious problem before calling maintenance and repair technicians. The truth remains that trying to cut corners by skipping preventive maintenance usually ends up being less
economical. Not only can preventive mould maintenance keep companies from paying for costly repairs to their moulds, it can also greatly extend the working life of the plastics processing machines. Email:anwesh.koley@network18publishing.com
Following are the guidelines for mould cleaning and maintenance:
94
Create a maintenance schedule and stick to it. Manufacturers should perform cleaning, inspection and maintenance of moulds after they have undergone a set number of cycles. Setting the schedule can be tricky. This is because different moulds age at different rates and conditions wearing them out differ from one manufacturer to another.
Keep a log of all necessary mould maintenance and repairs. Knowing how often a given type of mould breaks down without maintenance can help factories determine the frequency of inspections. Manufacturers of the injection moulds will also be able to provide information on the frequency of mould maintenance. Manufacturers must be acquainted with the environment in which the mould will be functioning.
Mould changes can be performed quickly if they are ready for use when they leave the store and can go into production without the need for major assembly or cleaning work. Every injection mould must be a self-contained unit. Parts or groups of parts that are loaded or borrowed often disappear or are needed elsewhere just when the mould is scheduled for use.
To know how often a mould must be maintained, one must consider the environment in which it is used â&#x20AC;&#x201C; how much moisture, pressure and extreme temperature it is exposed to. Moulds used with more abrasive materials will also need maintenance more often. Also, how often a mould needs maintenance depends on the kind of product it is used for.
It is especially important to pay attention to hot runners and water lines, as they often cause mould performance problems. Mould maintenance should also include lubrication, cleaning and tightening of all parts. Rust prevention sprays must be applied to a cool, dry mould if they are to work efficiently. This reduces f riction within the mould.
Cleaning work should be kept to a minimum, as it delays production. Specific requirements such as store cleanliness and ambient conditions must be imposed to preserve injection moulds. Damp rooms promote corrosion. The mould store should be kept at a constant temperature dehumidified constantly. This does not require much equipment and soon pays for itself.

Revving up the Asian growth engine Being the world’s fifth biggest producer and fourth biggest exporter of plastics and rubber processing machinery, Taiwan is all set to host the 13th edition of the biennial Taipei Plas. Here is a brief description of the country’s key strengths as well as the advantages it offers for the Indian plastics industry. Annabel Dsouza
T
aking forward the legacy of Asia’s burgeoning plastics industry, the biennial Taipei International Plastics & Rubber Industry Show has become one of the leading events in the region. In its 13th edition, Taipei Plas 2012 will be held from September 21-25, 2012, in the Nangang Exhibition Hall at Taipei World Trade Center (TWTC). Co-organised by Taiwan External Trade Development Council (TAITRA) and Taiwan Association of Machinery Industry (TAMI) since 1987, the show will witness more than 450 exhibitors occupy over 2,500 booths. Taiwan has been ranked as the world’s fifth biggest producer and fourth biggest exporter of plastic & rubber processing machinery. With quality design and highly competitive prices as their advantages, Taiwan-based machinery manufacturers have taken giant strides in developing products for the global market. India
has emerged as a significant market for Taiwan. Although Taiwan entered the Indian market later than the Japanese and Koreans, it has achieved an incredibly high rate of growth. Since the Economic Cooperation Framework Agreement (ECFA) came into effect on January 1, 2011, Taiwan’s primary and secondary industries have benefited from tariff reduction and exemption, thus boosting the cost-competitiveness of Taiwan-made machinery in Mainland China.
Strong plastics demand in Asia Taiwan’s plastics and rubber machine industry has been developing for four decades. At present, this sector has about 250 manufacturers. The island’s Research and Development (R&D) has been fast as the sector follows the footsteps of those in Europe, North America and Japan in terms of quality & efficiency. Taiwan’s rubber and plastics machinery exports have risen by 14 per cent to more than $ 1 billion in 2011. It is a major supplier of injection moulding machines with

about 70 per cent of production exported to Mainland China, Southeast Asia, India, South Asia, the Middle East and African countries. With the demand for environment-friendly production systems on the rise, Taiwanese manufacturers have embarked on developing energysaving and eco-friendly models to suit the preferences of international buyers. Chao Yuen-Chan, Chief Executive Officer & President, TAITRA, avers, “Taiwan’s machinery industry has witnessed vast improvement in terms of global competitiveness. The cross-strait ECFA will help Taiwan’s machinery and products penetrate the mainland market, but certain factors that may affect the industry include appreciation of NT Dollar, the European Union Korea Free Trade Agreement (FTA) and the US–Republic of Korea FTA.”

Glimpses from Taipei Plas 2010
include ventures into new moulding styles, including the first injection-compression systems from the country as well as advancements in multi-part moulding with new stack/tandem/family moulding systems, new machines with higher speeds, tighter precision or new capabilities to help moulders enter new markets. New presses that apply electric servo drives to the hydraulic pumps for energy savings will also be shown – vertical machines included. Taiwan’s overall machinery industry is expected to recover with production value growing from 6 per cent to 9 per cent this year. This projection results from a study commissioned by the Economics Ministry’s Department of Industrial Technology under the Industrial Technology Intelligence Services (ITIS) programme. Industrial machinery is one of the largest sectors in Taiwan’s machinery industry in terms of production value. The sector includes woodworking machinery, plastics processing machinery, textile machinery, food processing machinery, printing machinery, chemical machinery, packaging machinery, among others. Other major machinery sectors include pumps, compressors and fans; conveyors and automation equipment; and mechanical transmission devices.
Focus on energy-efficiency Taiwan’s plastic injection moulding machine sector has been manufacturing energy-saving, short-cycle moulding, high-speed precision moulding, automated and customised systems to meet the varying needs of customers. They initiated industrial upgrade and moved towards
producing plastic injection moulding machines that are faster, more precise and efficient, safer and with advanced network applicability to meet future production needs. Leading plastic injection moulding machine manufacturers, such as Chuan Lih Fa, Fu Chun Shin, Victor-Taichung, Chen Hsong, Multiplas and Huarong, have all launched innovative products, including fast cycle Polyethylene Terephthalate (PET) preform production systems, mould labeling production systems, high-speed system injection moulding machines, two-platen injection moulding machines, vertical electric injection moulding machines and highspeed servo-hydraulic injection moulding machines. Plastic injection products can be applied in a comprehensive range of areas, including consumer electronics, medical equipment, automobile industry, information industries, optical components and other products. The machinery industry is benefiting from the establishments of machinery parks. This followed the success of industrial clustering in the Taichung Industrial Zone and other science parks in Hsinchu, central and southern Taiwan. This resulted in creation of Taichung Precision Machinery Park, Taichung Fongjhou Industrial Technology Park, Chiayi Dapumei Machinery Technology Park and Changhwa Erlin Precision Machinery Park. The machinery industry’s future directions have been outlined in various programmes where the industry is being eyed as the next trillion-dollar industry after the semiconductor and photovoltaic industries. Among the sub-
sectors being lined-up for promotion are mould, spare parts and components. The policies formulated in accordance with these targets include the Trilliondollar Machine Industry Plan, Plan for Multiplication of Machine and Spare Parts Production Values as well as Plan for Localization of Screen Equipment. These three major plans have integrated technologies, manpower and resources from the industrial, government, academic and research sectors – all geared to turn Taiwan into one of the top three major machine parts suppliers in the world.
Looking East Taipei Plas 2012 promises to offer immense opportunities for the Indian plastics processing industry. India and Taiwan are estimated to double bilateral trade to $ 10 billion by 2015 through food processing, information and communication technology & electrical engineering tie-ups. This opens up many opportunities for strengthening the ties between the two countries as Taiwan’s relative machinery strength can be synergised with exponentially growing demand in India. Yuen-Chan concludes “Taiwan’s mechanical products with high quality and cost-competitiveness have attracted many overseas buyers. For example, the previous edition of Taipei Plas had drawn 18 per cent of foreign buyers from emerging markets, eg, Mainland China, the Philippines, Malaysia, Indonesia, Thailand and India, where rising demand for Taiwan-made plastics machinery in emerging markets was seen.” Email: annabel.dsouza@network18publishing.com

BOOK REVIEW
Poly(Lactic Acid): Synthesis, Properties, Processing and Applications Editors : Rafael Auras, Loong-Tak Lim, Susan E M Selke and Hideto Tsjuji Price: ` 8,624
Nano- and Micromechanics of Polymers: Structure modification & improvement of properties Authors: Goerg H Michler and Francisco J Balta-Calleja Price: ` 14,393
Polylactic Acid (PLA) cannot be considered as a new polymer, as the first molecule was synthesised as early as 1845. The increased availability of PLA stimulated growth in scientific and industrial research & development activities. Thus, the number of publications on PLA increased over the past decade. This book attempts to consolidate all the relevant knowledge about PLA in a single source. The book is organised in to five parts. Part I deals with chemistry and production of lactic acid, lactide and PLA. Part II includes polymer-related properties of PLA, with emphasis on chemical structure and optical, crystallisation, thermal, rheology, mechanical & permeation properties. Part III covers processing and conversion of PLA by conventional techniques. Blends with starch and other fillers & reinforcements are also covered in depth. Part IV describes degradation and environmental issues related to PLA. Degradation by hydrolytic, enzymatic, thermal and biodegradation techniques is explained in detail. Part V covers applications ranging from medical, packaging and textiles to environmental applications. The volume skilfully brings together the work of many contributors in an elegant flow of information and knowledge. The volume is recommended on the shelf of every library. It will serve as a singlesource encyclopaedia for students, research scholars, scientists and those interested in learning more about PLA.
Mechanical properties of polymer materials are relevant for all applications including household, medical, agriculture, automotive, microelectronics and aerospace. Improvement in properties and fitting specific properties to define applications has been the endeavour of polymer research. Thus, in the last two decades, the interest in polymer systems has shifted from micron scale to nanometer scale; hence, the worldwide trend today is to produce nanostructured materials, and consequently, miniaturisation of components needs better understanding of nano- and micro-mechanics of polymers. This book is organised into 12 main chapters. Chapters 1 & 2 explain the basic concepts related to materials and the tools used in characterisation of nano- and micro-mechanical analysis of polymers. Chapters 3 to 5 describe the general mechanisms of deformation and fracture. Chapters 6 to 12 cover the classes of polymer materials, including amorphous, semi-crystalline, blends and alloys, composites, rubbertoughened polymers, composites, nanostructured polymers and special forms of polymers used in niche applications. The book reviews research of academia and industry on key parameters that affect polymer mechanical properties, with a comprehensive overview on knowledge in the field of morphology, nano/micro-mechanical and failure mechanisms. It gives a description and illustration of relevant correlations on basic experimental results and microscopic investigations. Mathematical models and theoretical analysis are used to explain the mechanisms. The book is a valuable guide for researchers, chemists and engineers, material scientists in academia & the industry to understand the principles of mechanical properties and for improving these.
