EDITORIAL

PPP: Progressive platform for plastics… he famous line of Robert Frost – …And miles to go… – is quite significant in the current context of India’s economy. Although the country’s economic progress in recent years has brought about certain changes in basic infrastructure, there is a clear and critical need for its further expansion in a fast-phased manner considering the demand dynamics of a burgeoning populace. Like any other sector, the fate of plastics industry also factors this. Moreover, there is an ever growing emphasis on sustainable processes and technologies that will not only meet today’s needs, but also have adequate provisions for tomorrow.

In this scenario, the much-needed scale-up in India can be achieved if both the public and private sectors join hands through Public Private Partnership (PPP) rather than trying to individually tackle this imminent challenge of enormous proportion. Although PPP appears to be a win-win situation for all stakeholders, the key to success in such projects lies in effectively managing the interests of public and private sectors across different roles. Also, considering PPP experience in different sectors, some key implementation aspects of PPP need to be well-defined and communicated to all concerned parties before initiating a PPP project. With fast evolving socio-economic landscapes of India and the resultant demand drivers pertaining to numerous industrial and consumer segments, the role of the plastics industry, especially in devising an optimum life-cycle strategy involving virgin resins, plastic products and recycled resins, cannot be emphasised more. Further, since this has a direct bearing on three key stakeholders – consumers, industrial producers and the government – applying a PPP concept here seems to have a promising potential. For a sustainable, standardised and scalable PPP model in the country, there is a need to have a futuristic as well as facilitating framework in place, with a clear mandate of three Ps – people, processes and performance.

Although there is an air of optimism surrounding PPPs in the country at the moment, a comprehensive analysis calls for its judicious use in a customised manner as per the need of the particular sector and circumstances. This will entail clearly demarcating specific roles, rights and responsibilities; setting precise standards; providing training to various stakeholders; and fine-tuning the process on a regular basis to enhance the efficacy of the system. Only time will tell whether the proposed PPP model will usher in a new growth paradigm for the plastics industry.

Crude oil prices adversely affect polymer prices

D S Rawat

According to a study conducted by The Associated Chambers of Commerce and Industry of India (ASSOCHAM), the international oil prices and Rupee exchange rate have been moving in opposite directions, thus denying Indian polymer importers the benefit of drop in rates of crude oil in the international market. The study, which analysed the dynamics of oil prices and India’s import bill during April 2009May 2012, revealed that with the devaluation of the Indian Rupee and increase in global crude oil prices, Indian polymer buyers have been facing a rise in their import bills. Yet the oil import bill in rupee terms largely shows an increasing trend, which has not benefited polymer importers on their prices. D S Rawat, Secretary General, ASSOCHAM, said, “The benefits of lower international prices were either offset by a faster depreciating Rupee or a slower appreciating Rupee, and this could not offset the negative effect of a sharper rise in international crude oil prices, thereby resulting in a higher import bill. This has a direct impact on the plastics industry, which is heavily dependent on crude oil imports.” Further, the crude oil imports and its impact on government finances are dependent on import quantity, international price of crude oil and the exchange rate.

Sixth symposium for Plastics Processing a huge success

With over 200 visitors and 18 presentations on ‘New Trends in the plastics industry’, the sixth Plastics Processing conference held recently by the KREYENBORG Group in Muenster, Westphalia, was a major success. The presenters in the conference included polymer giants from across the globe. The attendees received considerable information on the latest happenings in the polymer industry. Jörg Auffermann from BASF presented the fully biodegradable product Ecovio®, which is made of renewable raw materials, and Ecoflex®, the familiar BASF biodegradable plastics based on petrochemicals. Innovations in underwater pelletising technology were showcased by Frank Brauer from BKG Bruckmann and Kreyenborg Granuliertechnik GmbH. In an interesting presentation, Dr Thomas Grimm-Bosbach from Seebach GmbH explained that the polymer industry is driven by cost pressure (higher throughput, longer lifetime) and required product quality through finer filtration of optical quality. He opined that modern melt filters must fulfill these requirements. The optimisation of melt filtration is done by enlarging the filter area, using the smallest possible unit, adjusting the filter medium to the customer process as well as choosing the right filtration technology.

Sumitomo Chemical consolidates its position in India With a presence for over 14 years in India, Sumitomo Chemical enjoys a position of leadership in the Indian Polymethyl Methacrylate (PMMA) market. In order to consolidate and grow further, Sumitomo Chemical– Singapore has aligned with J P Plaschem, Mumbai. J P Group presents a one-stop-shop solution for its customers, thus providing a significant value addition to the business of SUMIPEX PMMA, the acrylic resin from Sumitomo. SUMIPEX PMMA, from Sumitomo Chemical - Japan, is produced by the Sumitomo technology at their wholly owned subsidiary Sumitomo Chemical Singapore at the Singapore plant. “There is tremendous potential for acrylic in cosmetic packaging. Big companies such as Revlon, Maybelline and ELLE 18, use acrylic for their cosmetic packaging. Since most of these companies have entered India, they will slowly increase the use of acrylic in their product packing. At present, Indian companies such as Lakme and Emami have also begun using small quantities of acrylic in their packaging. This will ensure better aesthetics and be more expensive than normal polymer packaging. It is environmentally sustainable, as it is a recyclable polymer. Also, since the usage is not expected to reach the proportions of Polyethylene or Polypropylene (PE/PP), this will not be harmful in the least,” said M A Bala Gopal, Head-International Business, J P Group.

Breakthrough for Indian scientists in degradable plastics A three-member team of scientists f rom the Institute of Chemical Technology, Mumbai, have developed an oxyodegradable polymer by combining plastic granules with a catalyst, which enables the plastics to break down to smaller chains under direct sunlight. Although this technology has been available since quite some time, what differentiates the new approach is that these smaller chains are eventually consumed by bacteria present in the soil. The catalyst works on any type of plastics and facilitates its oxydegradation, ensuring that it does not pose as a health hazard or threat to the environment in the long term. “As the molecular weight declines due to oxydegradation, this gives the microorganisms access to carbon and hydrogen, allowing plastics to function as a nutrient for fungi and bacterial, thus enabling complete degradation,” said R N Jagtap, Head Department of Polymer & Surface Engineering, Institute of Chemical Technology. The efforts made by the research team for nearly half a decade in a tenacious process of discovery have finally yielded results. Moreover, the metallic catalysts are not derived from toxic heavy metals, and the team is in the process of acquiring a patent for the technology that could revolutionise how plastics is looked upon at present.

TECHNOLOGY & INNOVATION

New locked blow and fill system

Light guide panels by Arburg

KHS Corpoplast, Germany, has introduced its blocked blow moulding system, a combination blower, filler and capper unit that can be used in Polyethylene Terephthalate (PET) applications. The InnoPET BloFill blocked system is designed to increase efficiency and cut costs by filling in-line after blowing. The system connects the blower directly to the filler and capper unit, cutting out the air conveyer, bottle rinser and other components. Arburg has developed a hydraulic compression moulding machine designed for a 0.5-mm-thick optical application. The light guide panels are moulded with a thin optical panel intended for use in tablets and Thin Film Transistor (TFT) screens, using Light-Emitting Diode (LED) lighting; also, the mould cavity does not close completely. The hydraulic Allrounder 630 S has a clamping force of 250 tonne and operates with a two-cavity mould. It maintains a 1-mm gap until the last 50 millisecond of the process. The mould, in turn, must be designed so that the cavity is sealed, even in the partially open state. This process helps reduce shrinkage and deformation and can accommodate precise moulding specifications. The light guide panel features nearly imperceptible ridging and changes in thickness at the edges, designed to ‘guide’ LED light from the edges of the panel. Most tablet panels are lit from behind, but the light guide panel can be lit from the edges and maintain even brightness across the entire surface of the panel.

New LVT eliminates problems in extrusion blow moulding of polyolefins The new Liquid Vehicle Technology (LV T ) developed by Clariant Masterbatches has the capability to eliminate many of the problems that have prevented wider use of liquid colour and additive concentrates in extrusion blow moulding of polyolefins (high- and low-density polyethylene and polypropylene). 34

Instead, a multi-functional star wheel conveys the bottles from blower to filler by way of a transfer block. The block separates the dry blowmoulder from the wet filler and includes an airlock with constant air flow. The base system can be used for water or other non-carbonated soft drinks and can make up to 72,000 bottles per hour. With some modification, the system can also be used for carbonated beverage applications and hot-fill applications at 185-190°F (85-88°C).

Sim-pull closures foil tamperers Two all-in-one foil closure solutions for the food industry have been launched through a licence agreement between Dorking-based Bapco Closures and Aptar. The new Simpull and Trilogy closures both feature a proprietary Bonded Aluminiumto-Plastic (BAP) technology, which claims to provide ease of opening, built-in tamper-proofing and excellent seal integrity. The Sim-pull solution has a fliplid design, allowing consumers to open lids with one hand, according to Bapco. It is designed for a diverse range of contents including snack and granular products such as nuts, crackers, baking agents and sweeteners. A variety of ring-pull configurations enable manufacturers to tailor the closure to their particular product specifications. The Trilogy is a two-piece spout and closure design.

Initial testing in monolayer containers demonstrates that these highly compatible systems allow for higher pigment loadings and lower usage rates, while practically eliminating past challenges related to screw slippage. Improved resin compatibility results in stronger weld lines in the finished container as evidenced by the scores of standard burst and compression-loading tests. The new masterbatches use a liquid vehicle system that incorporates

These new solutions meet the growing demand for re-sealable closures for on-the-go and at-home eating. These are perfect for occasions when customers want to consume a single portion of food and save the rest for later. Because of their ease of opening feature, Sim-pull and Trilogy are particularly suitable for elderly consumers and children. suspension aids, and binders have been incorporated into the new LVT masterbatches to allow for higher pigment loadings and, in most cases, lower usage rates. Additional components enhance flow and make for dramatically faster colour changes. The benefits of this technology include improved weld-line strength, better processing characteristics, faster colour changes and greater productivity.

Leading the youngest subsidiary of European machinery manufacturer Wittmann Battenfeld in India, Nandakumar outlines the core requirements of the Indian plastics industry to compete on the global front, in an exclusive conversation with Annabel Dsouza…

Modern Plastics & Polymers | July 2012

Nandakumar T

What are the current growth dynamics for the plastics industry in India? Indian plastics processors are innovative, dynamic and demanding. They require technological leadership, together with outstanding service and short response times. With this competitive spirit, the Indian plastics market has grown consistently over the last few years. But, the need of the hour is innovative automation and robotic solutions to keep pace with global developments. Most processors are aware that resins represent a significant percentage of their overall part-cost, yet they often do not realise the true cost savings available to them from efficient handling and control of resins. Material handling is an area where many processors are now looking at in order to reduce their input costs and improve overall operation without making a significant capital investment. Simplification of controls and operation of equipment is critical for processors facing a shortage of skilled personnel. As the Indian plastics industry seeks energy-efficient equipment to reduce manufacturing costs, Wittmann Battenfeld is making a great impact in delivering low-consumption, high-output solutions.

How would you describe the journey of Wittmann Battenfeld in India? Wittmann is dedicated to robotic and automation technology for the Indian plastics processing machinery market. After its formal incorporation in December 2006, Wittmann India was renamed as Wittmann Battenfeld India Pvt Ltd, after just one and a half year, reflecting our broad sales & service synergy with Wittmann’s acquisition of Battenfeld in April 2008. Since then, the Indian company has enjoyed uninterrupted growth. This does not only reflect in our marketshare, but also in the growth of our team in India. Completing five years in India, we continue our journey towards being a complete solutions provider for the Indian plastics industry. This being our core strength, we are developing better

solutions for this challenging market to further strengthen our position.

How can machinery makers overcome cost-quality pressures in India?

What are Wittmann’s R&D initiatives in India and globally?

Not only the size, but requirements for quality and efficiency are also growing in the Indian plastics market. At present, the drive for leading technology is becoming a major decision factor. Speed, consistency and energy-efficiency are the uncontested requirements for every production unit. As Indian manufacturers recognise the value of these advantages in the domestic and export market, quality scores over price as a key concern of the globally competitive manufacturer. Wittmann does not compromise on quality irrespective of the price factor. Our cost-competitive solutions are designed as per manufacturers’ specifications. We maintain a standard quality policy, thus strengthening our base in India. We believe in technology consistency and transparency across the world through all our subsidiaries.

We believe in lean production and global technology to supply the plastics processor with the best possible technology at competitive prices. Wittmann’s Research and Development (R&D) has increasingly centred on environmental aspects, with innovations to reduce energy & oil consumption and noise level by establishing a true modular concept. Once these early concepts are decided upon, we develop the prototype and study its feasibility in an increasingly competitive market. Wittmann’s R&D also focusses on simplification of controls to develop easy-to-use, open machines thereby simplifying the shop floor for the operator and manufacturer. In order to maximise equipment output and ensure standards of quality & consistency, processors are relying more on automation and reducing dependence on skilled personnel. When we launched operations in India, our priority was to adapt Wittmann’s solutions to Indian conditions of temperature, humidity and power supply. Currently, many of the software R&D projects at the Wittmann tech centre in Vienna are being developed as per Indian specifications.

What are your current focus areas and future strategy? We are currently the third largest player in the plastics processing machinery automation space in terms of market value. We are expanding our presence in India through a larger shop floor, which is likely to begin operations by mid-2012. We expect a 40-45 per cent jump in revenue through a well-defined sales and service network across India. Industrywise we are focussing on medical devices, automotives and white goods manufacturing. Due to high growth rates in these industries, and the need for precision & high productivity, we are witnessing a rapid shift from conventional manufacturing to automation & robotics. As a global player in the plastics machinery space, Wittmann Battenfeld is present in all major markets of the world. But, the Indian subsidiary has also exported to countries like Uzbekistan, South East Asia and South Africa. We remain committed to the Indian market and are currently establishing a

How important is sustainability for plastics processing machinery? Machinery manufacturers play a pivotal role in making the plastics industry competitive on the sustainability front. Energy saving is possible across the entire system by selecting the right equipment and dimensioning it as per product analysis, measurements and readjustment of the process. Wittmann supports this cause by developing energyefficient automation solutions. This needs creating a culture of energy consciousness. We have done this by putting the star rating stickers on our equipment. We are the only company in the Indian plastics industry to have this energy rating sticker.

The ability to produce light-weight, cost-effective plastic products without compromising the tensile strength makes thermoforming one of the most sought-after methods and a viable option for plastics processors. Anwesh Koley looks into the latest technologies used in this process to offer high-quality end products.

ith the rapidly rising price of commodity polymers, the scenario in the plastics market has undergone a change. Many plastics processors have entered into thermoforming through acquisition of companies in this industry in order to remain a competitive supplier of containers, particularly to the dairy market. The reason is orientation strength, which is achieved by thermoforming as it is done below the melting point of the polymer, particularly with Polypropylene (PP). Owing to these benefits, it is possible to produce containers such as those used for dairy products with much thinner walls, but having the same compression strength as their injection moulded 46

equivalents. S C Dutta, Managing Director, Shalimar Thermoforming Pvt Ltd, says, â&#x20AC;&#x153;The thermoforming industry is flourishing in India. The process finds wide applications in the day-to-day life, eg, catering items, food trays/packs, cups and glasses, beverage containers, bakery packaging and large industry applications.â&#x20AC;?

Preference for the process The customer today demands lightweight packaging for most of his/her daily requirements. Thermoforming offers the advantage of manufacturing thin-walled products, which help in weight reduction. Therefore, more and more entrepreneurs are entering the thermoforming process industry. An important issue here is that entrepreneurs consciously manufacture products from quality/virgin plastics/

polymer to meet the environment norms. Plastics find various applications in every day usage. However, in manufacturing of packaging material or containers, trays and boxes, PP and Polystyrene (PS) are fast gaining ground in terms of usage, while thermoforming is the most widely used technique for making finished products. The ongoing development of new materials, equipment and tooling technology has enabled thermoforming to find applications in areas that formerly utilised paperboard, glass, metal, wood, Expanded Polystyrene (EPS) foam, etc. â&#x20AC;&#x153;Compared to other plastics processing techniques (injection moulding, blow moulding), thermoforming offers lowcost tooling, fast, inexpensive prototyping, shorter production lead times, custom designs that can be easily modified, thin-

walled products, demand flexibility and exceptionally large part capabilities. Thus, thermoforming facilitates ideas to reality,â&#x20AC;? says Dutta.

Application areas Thermoforming is a secondary shaping process, the primary process being one that produces the sheet or film. Only thermoplastics can be thermoformed, since extruded sheets of thermosetting or elastomeric polymers are cross-linked and cannot be softened by reheating. Common thermoforming plastics are PS, cellulose acetate and cellulose acetate butyrate, Acrylonitrile-Butadiene-Styrene (ABS), Polyvinyl Chloride (PVC), acrylic (polymethylmethacrylate), polyethylene and PP. Mass production with thermoforming operations is done in the packaging industry. The starting sheet or film is rapidly fed through a heating chamber, which is mechanically formed into the desired shape. The operations are often designed to produce multiple parts with each stroke of the press by using moulds with multiple punches and cavities. â&#x20AC;&#x153;In some cases, the extrusion machine that produces the sheet or film is located directly upstream from the thermoforming process, eliminating the need to reheat the plastics. For optimum efficiency, the filling process to put the consumable food item into the container is placed immediately downstream from thermoforming,â&#x20AC;? says Dutta. Thin film packaging items that are mass produced by thermoforming include blister and skin packs. These offer an attractive way to display certain commodity products such as cosmetics, toiletries, small tools and fasteners (nails, screws, etc). Thermoforming applications include large parts that can be produced from thicker sheet stock, eg, covers for business machines, boat hulls, shower stalls, diffusers for lights, advertising displays and signs, bathtubs, toys, etc. The injection moulding process is often compared with thermoforming. However, thermoforming enjoys certain advantages, which make it the preferred

choice in many applications. Injection moulding has its limitations when it comes to size of product and cost of tooling. A typical injection mould tool will cost roughly 33 per cent more than a similar thermoformed tool, and the margin increases as the parts become larger. â&#x20AC;&#x153;Injection moulding does not have a good prototype process, as typically Stereolithography (SLA) or Selective Laser Sintering (SLS) parts that are used for prototyping, which offer limited comparisons to the actual final product, can be expensive, and are not of the same material with which the final product is made. Thermoforming, on the other hand, utilises a prototype tool made from wood or epoxy that can be used to create several finished parts of the product and formed from the same material with which the final product is made,â&#x20AC;? adds Dutta. Therefore, many possible design or fit issues can be caught before going to production tooling, thus saving time and money.

Compared to other plastics processing techniques (injection moulding, blow moulding), thermoforming offers low-cost tooling, fast, inexpensive prototyping, shorter production lead times, custom designs that walled products, demand

large part capabilities. S C Dutta MD, Shalimar Thermoforming Pvt Ltd

Areas to work on Thermoforming enjoys many advantages, but the industry needs to understand certain fundamental requirements to ensure steady growth. â&#x20AC;&#x153;An important concern is that thermoforming machinery, which is expensive since it is monopolised by only few manufacturers who are concerned only up to supplies and have not considered developing the skilled workforce to facilitate growth of the entrepreneurs. The after-sales service is also not up to the mark, which should be taken care of by machinery manufacturers,â&#x20AC;? believes Dutta. Also, remote areas and states have difficulties in terms of technical know-how, logistics,

with delays in after-sales service support, thus adversely affecting the industry. â&#x20AC;&#x153;A proper advisory should be issued to the manufacturers that it is in the interest of the country to promote and help the best as well as most efficient utilisation of machinery available in the country to avoid wastage of resources,â&#x20AC;? adds Dutta.

Roadblocks ahead The key challenge for the thermoforming sector in India is that the used disposable plastic and polymer articles are not properly managed and collected for recycling to avoid hazardous effects on earth. â&#x20AC;&#x153;The government, civil society and industry together must make efforts to create awareness and pass an ordinance to ensure scientific disposal of used plastics/polymers for ensuring environment safety, otherwise thermoforming sector cannot reach the desired heights in the coming years, which would be a huge loss for both the industry and the society,â&#x20AC;? opines Dutta.

Progress through process optimisation The Indian thermoforming industry is embracing new technologies and energy-efficient heating options for the machinery, with more and more organisations becoming aware of the need for energy efficiency. Anwesh Koley highlights some of the techniques that are helping this sector to increase efficiency.

he efficiency of thermoforming technology depends on varied applications that the process enjoys. Packaging is an important area where thermoforming is used. Thermoformed packaging refers to a type of retail packaging that uses thermoforming technology. In this process, a special type of plastics is melted to liquid form and frozen to a brittle, almost glass-like state. This type of thermoformed packaging is preferred for various applications and industries, such as dairy and food packaging, as well as cold beverage cups.

The thermoforming technology provides cost-efficiency and high quality of polymers used in packaging. V Vikram, Proprietor, Sealers India Agencies, says, â&#x20AC;&#x153;Thermoformed packaging materials are stiffer than average packaging, transparent and provide a barrier against external flavours or odours, keeping the food products inside fresh. This feature keeps the package from smelling like the food product inside it. This packaging has anti-fogging characteristics and resistance to grease & oil.â&#x20AC;?

the

process that uses continuous forming of roll-fed thermoplastic sheet through an oven tunnel into a forming station, from trimming to picking and packaging. This is a more automated process than heavy gauge. Thin-gauge is used extensively in the packaging industry. The heavy-gauge division of thermoforming feeds cut thermoplastic sheets into a machine that carries the sheets through one or more heating stations to the forming station for moulding and then out of the machine. Here, secondary steps are necessary to trim the finished part. Trimming includes sawing, routing, shearing and drilling. â&#x20AC;&#x153;In the early days

of heavy-gauge thermoforming, an acrylic thermoplastic sheet was hung in an oven to absorb heat. The material was then stretched over a mould. After allowing it to cool, it was removed and trimmed. Drape forming is still used for various applications in the manufacturing of many products,” says Vikram.

Vacuum thermoforming This process utilises heat and suction to shape the plastic sheet onto the desired mould. A secondary operation is required for trimming features such as cutouts and holes. This technique is best used for large, light-weight parts or textured or coloured parts that do not require finishing. It is easy to create a mould, allowing for quick turnaround time, and is well suited for prototyping and short- to medium-run production of thick-gauge parts. Vacuum thermoforming provides the solution for simplification and aesthetics enhancement for products such as panel covers, trays, dividers, guards, pans and display cases.

Applications to improve accuracy Heavy-gauge thermoforming is serving all industries today. New applications include building and construction products, products for the electronics industry, usually replacing injection moulded parts, and products for the heavy trucking industry and automotive manufacturing. In automotive, the matched moulding system is commonly used for forming doors, headlining panels, wheel well openings and closeout panels in the boot. A variation of drape forming and match moulding (slip forming) utilises a mould with a matching plug assist where the material is free to slip into the mould configuration. Slip forming is commonly used in automotive manufacturing for forming carpeting. “Another important industry served by heavy-gauge thermoforming is sanitaryware, which includes bathtubs, shower tubs and stalls and wash basins. The materials generally used are Acrylonitrile Butadiene Styrene (ABS), vinyl, acrylic and/or acrylic over an ABS substrate. Some manufacturers use cell cast acrylic, heating the sheets in

the convection oven and using vacuum to form the part,” adds Vikram. Other methods use ABS with a co-extruded top coat of acrylic. This is usually formed on standard thermoforming equipment. The surfaces are then reinforced with fibreglass (woven or chopped fibres) or sprayed urethane foam. A new, recently introduced process uses thermoformed finished surfaces with a waffled thermoformed material back panel, reinforced with cast urethane foam between the two parts. The appliance industry uses vacuum forming to produce interior boxes and door liners in refrigerators. The common materials used here are polystyrene and ABS. The trimmings of refrigerator parts are moving from massive punch die to fiveaxis robotic router trimming. The industrial pallet industry is moving rapidly from wood boxes and pallets to twin-sheet thermoformed products. The materials used are generally high-density and high-molecular-weight polyethylene. The automotive and food industries have been driving this change because of the increasing demand for recyclable containers and pallets. This represents an excellent opportunity for plastics and thermoforming. Thermoforming technology can also be used if long packaging lines arise as a result of the output level and many functions. The principle of the jumbo tray comes into play here, as a complete array with trays is formed first. After being formed, this array is separated into individual trays with a cut across the film running direction and placed on a transmodule, which can then move through the line according to the tasks to be carried out. “If several transmodules are lined up for coupled mode, patented continuous counter-running can be utilised for picker line operation. Here, products move through the packaging line from one side and the packaging materials from the other side,” says Vikram.

Areas of growth The highest material growth in thermoforming sheet is in high-density and high-molecular-weight polyethylene.

The acceptance of welldesigned, quality built temperature-controlled forming moulds, which allow tighter control of part dimensions, residual internal stress and ability to make repeatable parts, have made heavy-gauge the preferred technique for various thermoforming requirements. V Vikram Proprietor, Sealers India Agencies

These materials have high impact, heat, chemical and weather resistance. Polypropylene is also beginning to appear in heavy-gauge thermoforming. In addition, higher temperature, higher performance engineering materials such as ABS and polycarbonate are used where standard polyethylene or polypropylene do not have sufficient properties. The heavy-gauge thermoforming technique has also grown and increased production & efficiency. It offers better quality sheet. Precision controls of the heat and forming cycles at regular timings ensure better production quality and final products. “The acceptance of well-designed, quality built temperaturecontrolled forming moulds, which allow tighter control of part dimensions, residual internal stress and the ability to make repeatable parts, have made heavygauge the preferred technique for a range of thermoforming requirements,” concludes Vikram.

“Niche packaging plays a special role in the retail space” …emphasises Franco Gornati, Managing Director and Chief Executive Officer, FNC SpA Group, the holding company of Veripack Solutions India Pvt Ltd. He highlights the recent innovations in plastics thermoforming and their relevance to the Indian packaging industry, in an exclusive conversation with Annabel Dsouza. What are the current innovations in the thermoforming industry? The Indian market is currently witnessing enormous progress, with the packaging sector moving from basic formats to more advanced technology. Today’s customer likes to have the popular formats of the developed world, eg, Modified Atmosphere Packaging (MAP) packaging, vacuum packaging, etc. Such special packaging formats have a direct correlation to the product shelf-life and aesthetic look of the final pack. Niche packaging plays a special role in the retail space and is allowing packaging manufacturers to compete with global competitors in terms of best quality and value-added solutions. Rollstock thermoform–fill–seal technology is one of the most mature packaging formats widely used in the West to achieve enhanced shelf-life; this technology ensures packaged product integrity and is also combined with high aesthetics. Generally, the machine uses two continuous rolls of film, which would be the lower thermoformable film and the upper lidding film. The benefits of this technology are enormous, not only in terms of enhanced product shelflife, but also product integrity, high convenience factor, high aesthetic quality. These features ensure that convertors stay at the top of the market and have satisfied customers at the end of the supply chain.

“Thermoforming offers a fast way to manufacture light-weight products” …asserts Vir Singh, Proprietor, Sai Thermoformers. In an exclusive interaction with Anwesh Koley, he explains the current scenario of the thermoforming industry in India and what can be expected from this industry in future. shortcomings. Many other thermoforming processes use a resin base in powder or pellet form. Vacuum forming begins further down the line with an extruded plastic sheet, which incurs an additional process, and therefore, an extra cost to reach this stage. Generally, a part of the material is cut away from the formed part, which, unless reground and recycled, has to be considered as scrap and accounted for in expenditure. However, these problems have been invariably resolved by strict control of sheet quality and intelligent mould design to minimise wastage.

What are the advantages of thermoforming over other plastics processing techniques? How do you see the performance of thermoforming industry in India? The thermoforming industry in India is witnessing a steady growth as a result of an increase in application from the packaging industry. Packaging is by far the most known application of thermoforming. This versatile process has helped modernise several industries such as automotive, medical, non-conventional energy sectors and a long list of others. Thermoformed parts have become important in two main areas – structural and functional parts and low-cost, highperformance packaging applications. The advantages of thermoforming are the significantly lower tooling costs and lead times, as compared to injection moulding or other closed-cavity methods.

How do you see the progress of this technology in India? The thermoforming industry has developed despite two fundamental 54

Modern Plastics & Polymers | July 2012

Thermoforming offers several processing advantages over other techniques such as blow moulding, rotational and injection moulding. The technique requires fairly low forming pressures, thus enabling the use of comparatively low-cost tooling and economical fabrication of relatively large-sized mouldings, which would be otherwise cost prohibitive with other processes. Since the moulds witness relatively low forces, these can be made from relatively inexpensive materials and mould fabrication time kept reasonably short. This results in comparatively short lead times. It provides the perfect solution for prototype and low-quantity requirements of large parts as well as medium-size runs utilising multiple moulds.

What are the challenges facing the sector? Chinese manufacturers are the biggest threat to us. We follow a single quality standard, while they have different

product ranges for different consumers. The customer willing to pay a high sticker price can opt for a high-quality product, while the one looking for quantity and bulk purchase also has his options, so Indian manufacturers have little to offer. International customers prefer Indian machinery, as these are of better quality, and there is scepticism regarding the quality of Chinese products. They produce in bulk, while we offer quality, and most of our customers prefer quality. The Chinese lag behind the Indian manufacturers in terms of reliability. Domestic consumers do not even prefer to buy machinery that has Chinese parts, let alone buying Chinese machines. Thus, we do not even use Chinese parts for our machinery.

What are the current key requirements for this sector in India? With cost reduction and competition, the quality of thermoformed products is feared to go down. The thickness for thermoformed products should be set and made mandatory or else, quality gets compromised. While growth is expected in the flexible packaging industry, consumers are preferring rigid containers, whose quality can be ensured only by prescribing a minimum thickness for the product. Another important factor is the confidence of investors in the sector. With rapid implementation of stringent norms by the Government, new entrepreneurs are often afraid to venture in this industry thinking that they might soon have to look for alternative business avenues. The fear of ban has been rampant for quite some time, and this hinders fresh investment in this sector. Email: anwesh.koley@infomedia18.in

Is the Indian thermoforming industry ready to compete on a global scale? Although thermoforming companies have been successful in catering to the varied requirements of packaging in India, it remains to be seen how well placed domestic companies are to meet the current demands of a market highly influenced by international trends. Anwesh Koley gauges the opinions of some industry experts on the preparedness of the market to compete on a global level. Dipak Vyas Director, Neo Pack Enterprises

Govind Bhandari

The thermoforming industry in India is witnessing an upwardmoving graph. The demand for light, recyclable, yet rigid, products is on the rise and thermoformed articles enjoy a market that is benefiting from the above characteristics. The plastics and polymer industry has a wide range of applications in the daily life of people, as it has been substituting most items for over a decade, particularly thermoformed catering items such as food trays, packages, cups, glasses, other beverage containers, bakery and sweets packaging, besides other large industry applications. Thermoforming yields a part with the same aesthetic properties as an injection-moulded part, but at a fraction of the tooling expense involved in injection moulding. In India, there is a constant need to have light-weight packaging, as it offers rigidity and is cost-effective. This renders thermoforming as a better technique. Considering the current requirements of the Indian packaging market, thermoformed products currently made are fit for the international market.

Although demand for thermoforming machinery is high, competition is increasing both at the domestic and international level. The biggest threat currently is from Chinese manufacturers. We follow a single quality standard, while they have different product ranges for different consumers. The customer willing to pay a higher price can opt for a highquality product, while the one looking for quantity and bulk purchase also has his options; thus, Indian manufacturers have little to offer. Although international customers prefer Indian machinery, which are of better quality, they are sceptical about the quality of Chinese products. It remains to be seen how far domestic technology can match up to international standards and the changing customer requirements. While the thermoforming sector faces several challenges, customer demand and global trends have a long way to go in determining the future of this industry. At present, we require more support from the government to be better prepared to face competition from international companies.

Manager, Dr Froeb (I) Pvt Ltd

Editorial take:

While the thermoforming industry is growing due to the varied applications it enjoys, new methods have enhanced the quality of finished products. This is due to the increased use of engineering plastics. Earlier, only polypropylene and polystyrene were used, but now polyvinyl chloride is also being used. With the availability of raw materials in the market and increase in competition, manufacturers are forced to offer better quality at affordable prices. Although competition has often hampered our bottom line, it enables us to understand the customer better and makes us aware of the trends in the global market. H o w e v e r, international competition in terms of technology is yet to make heavy inroads into the Indian market. As most of the sector is unorganised, our markets are limited primarily to the local demand. This is also because thermoforming technology is still an unexplored area, though it has a lot of scope. With the advent of global competition in India, we can expect domestic players to gear up in terms of quality, which will enhance the scope for the process. Email: anwesh.koley@infomedia18.in

The domestic setup for thermoforming is suited for current requirements. However, since packaging is a dynamic market, customersâ&#x20AC;&#x2122; tastes keep changing frequently. Hence, thermoformers must adapt quickly to international requirements to retain their marketshare.

INSIGHT & OUTLOOK: Electrical grade plastics

Driving potential with low-cost alternatives The advent of engineering plastics has brought about a paradigm shift in the possibilities of plastics applications. Lionel Alva assesses the role of performance additives in resins that have facilitated the use of electrical grade plastics as well as their future avenues.

he low cost of production, energyefficienc y and ability to continually harness plastic waste, while offering better malleability and flexibility than metals, have made plastics the preferred material for almost all electrical grade appliances. The light weight and high-strength characteristics of plastics are some of the factors that affect ease of use, logistics and performance. These have been possible due to the polymer compounding process, which has expanded the scope of plastics applications.

Plastics in electronics The last decade has seen a phenomenal growth in the use of engineering plastics. Especially, additives that impart thermal conductivity to plastic compounds electrically or while offering antistatic properties are much sought after. The wider acceptance of such compounds in replacing metal (particularly aluminium) and non-conductive plastics is evident in their double-digit annual growth rates over the last decade. One reason is the decline in their prices with increasing applications 62

Modern Plastics & Polymers | July 2012

in electronics, computers, medical devices, automotive, aerospace and appliances. This is remarkable since plastics by itself does not offer heat resistance, durability or high tensile strength. Additives modify the properties of plastic resins during polymer compounding, making plastics a panacea for engineering applications. An example of the achievements with plastics and additive blends is the compounded grade of Polyphenylene Oxide (PPO) used in the manufacture of chassis. A plastic chassis part for a copier device must meet multiple service requirements to be effective. The part must be rigid and flat while the paper or plastic tape moves across the surface. It should have long-term stability, as any change in dimension affects the repeatability and accuracy of copies. Any medium moving across a good insulator will build up static electricity on the insulatorâ&#x20AC;&#x2122;s surface, which can curl paper and short out the sensitive electronic circuit boards. The plastic chassis, which is a good insulator, must provide a means for removing the build-up of

Electrical grade plastics

static electricity on its surface. The surface of the part must have dry lubricating qualities to enable the paper or plastic tape slide easily across the surface. These can be achieved with PPO plastic material compounded with additives.

Thermal properties modification Electrically conductive plastics have made significant inroads in Electrostatic Dissipation (ESD) for electronics packaging and automotive fuel systems and are growing in both metal replacement and safety applications, eg, Explosive Atmosphere (ATEX) environments. The range of application has broadened to include silicon-wafer storage boxes, thermoformed trays for electronic components, storage and transport containers, air-cleaner parts, conveyors as well as protective films, foils & bags. Unlike conventional migrating antistats used in packaging, ESD applications require longer-term protection and/or lower resistivity. These are better served by ‘permanent’ antistats such as carbon black, carbon and metal fibres and nanomaterials. These additives must show rapid charge dissipation and cleanroom compatibility & and low outgassing. Carbon black compounds and concentrates offer a good priceperformance ratio and account for a major portion of conductive plastics. But, although carbon black is effective in adding electrical conductivity, its adverse effects on mechanical properties is a drawback.

One of the fastest growing areas for conductive plastics is metal replacement for weight reduction. Among the most widely used heat-conductive additives are graphite fibres and ceramics such as aluminium nitride and boron nitride. “Computer, automotive, appliance and aerospace markets are welcoming thermally conductive plastic compounds for transferring heat away from sensitive electronic components. These are increasingly specified for heat exchangers, heat sinks, heat pipes, electronic interfaces, housings and transformers. The emergence of energy-efficient lightemitting diode lighting is also fast turning into a major growth area. Most specialty compounders have added some thermally conductive materials to their portfolios, aimed primarily at metal replacement. These offer lighter weight and good chemical resistance, making them an excellent alternative to metal heat exchangers that are susceptible to failure due to corrosion,” avers Aditya Tandon, Director, Classic Polymers.

Possibilities and limitations Thermally conductive compounds are generally not considered to be direct replacements for metals, but open up a range of new opportunities for ‘thermal management’ applications. Parts moulded from this new generation of materials can replace metals and ceramics in some applications, while non-conductive plastics in others. Uses include custom-moulded heat sinks on circuit boards, as well as tubing for heat exchangers in appliances, lighting, telecommunication devices and industrial equipment used in corrosive environments. Heat sinks often involve plastics overmoulded on a metal heat pipe. Lighting applications also include reflectors, laser-diode encapsulation and fluorescent ballasts. In temperature sensors such as thermistors, thermally conductive plastic encapsulation improves the response of the temperature sensor. Thermally conductive compounds are also used to encapsulate small motors and motor bobbins. The heat-transfer requirements of ever-

These offer lighter weight and good chemical resistance, making them an excellent alternative to metal heat exchangers that are susceptible to failure due to corrosion. Aditya Tandon Director, Classic Polymers

smaller and more power-consuming electronics have opened the door for this new generation of cooling materials. While unfilled thermoplastics have a thermal conductivity of about 0.2 Watt/ meter-Kelvin (W/mK), most thermally conductive plastic compounds typically have 10-50 times higher conductivity, ie, 1-10 W/mK.

Electrifying prospects Ensuring that electronics, lighting and car engines remain cool are some of the new roles for thermoplastics that have been formulated to replace metal or ceramic. Packing more powerful microelectronics into ever smaller spaces would not be possible without heat sinks and heat spreaders moulded from new thermally conductive thermoplastic compounds. In the Indian context, this provides a tremendous opportunity for Indian plastics processors to tap a lucrative market with enormous business potential.

INSIGHT & OUTLOOK: Micromoulding solutions

MINIATURISING

with precision

With electronic products becoming smaller and portable, the plastic components inside them are constantly expanding in performance but shrinking in size. Avani Jain analyses the micromoulding technique used for moulding tiny electronic plastic components at higher speeds and lower costs.

icromoulding technique is used to make extremely small-sized parts of electronic products. These parts are measured in micron. Micromoulding has opened the door to manufacturing tiny parts relatively easily at a lower cost and higher speed, and has thus increased profitability through material conservation as less resin is used to create more parts. Amit Mahant, Director, PK Plastic International Pvt Ltd, notes, “Micromoulding is a specialised, precision injection moulding technique specifically for moulding micro-miniature electronic components.” Micromoulding is designed specifically for producing the smallest components, typically, with component weights less than 0.25 gm and even smaller. It has many advantages, eg, greater accuracy in finished parts. Its major application includes plug connectors. Since the process is designed for smaller parts, few mould cavities are used in micromoulding. Thus, the accuracy and reliability exceed those of conventional moulding. New and unconventional part geometries are also possible using micromoulding. Material choices for micromoulded components range from commodity olefins and polypropylene to exotic, high-heat materials. Generally, in micromoulding, part weight is 0.001 gm or lesser and part size is 0.075-inch of diameter or smaller.

Machining parameters In moulding of electronic components, micromoulding can offer a range of cost64

Modern Plastics & Polymers | July 2012

effective alternatives for components that are small, complex and require highprecision tolerances. Mahant notes, “The one big reason for companies using this technology is the cost savings it incurs. That is because the time taken to mould a component is a fraction of the time taken to machine a component. Another reason is that designers generally do not want to have the possibility of entry of foreign matter into their electronic devices. Micromoulding eliminates the potential failure mode of having particulates left after machining. It also gives more freedom to designers to introduce intricate features in products, thereby enhancing their ability to create more innovative products.” He adds, “As the trend for smaller components becomes greater in the Electrical & Electronic (E&E) industry, micromoulding can make it easier to machine complex geometries. In addition,

this technology offers solutions to some common manufacturing issues specifically pertaining to the electronic device field, which has embraced micromoulding as a key enabling technology for making micro-electronic components.”

Basket of offerings Micromoulding solution offers numerous benefits in the moulding of electronic components. “It can be an excellent low-cost alternative to machining. Further, small parts require high-speed automation to maintain part consistency, complex, tight tolerance and flash-free moulding, which can be only achieved by micromoulding process. In a nutshell, micro-injection moulding is a lower cost solution, leads to dimensionally stable production process and causes no particle contamination; further, complex geometries can be achieved through this process. It uses alternative resins or fillers to improve mechanical and/or electrical properties, leading to better surface finish,” notes Mahant. Some other benefits include reduced tool sizes, increased part accuracy, improved cycle times, reduced part cost and defined colours.

Moulding success Control of the mould design and build process is essential to the success of any micromoulding project. Four key factors contribute to the success of any micromoulding project, ie, mould tool design & fabrication, micromoulding equipment used, the quality of inspection equipment used and the business

strategy. Mahant asserts, â&#x20AC;&#x153;These variables are critical for obtaining a specific micromoulded component, yet individuals sourcing micromoulded components commonly overlook one or more of them. Attempts to micromould components using conventional moulding equipment often fail due to various reasons. Therefore, a buyer must have adequate understanding of the mould tooling and the capabilities of the equipment being utilised, to be able to make an informed decision on whether the micromoulder can provide a successful product.â&#x20AC;? Conventional injection moulding machine has a high shot size relative to the barrel capacity. Mahant notes, â&#x20AC;&#x153;If plastic resin is left in the screw for an extended period, it will affect the mechanical properties of the plastic resin. The conventional machine screw, depending on size, can carry several hundred shots of material in the injection barrel. This is important since many conversions use highperformance plastics in their applications. These high-performance plastic resins have a high degree of thermal degradation. One way in which moulders try to alleviate this problem is by increasing the number of cavities in the mould to increase the shot size. This resolves the issue with the shot weight. The machine specifically designed for micromoulding process addresses the issues of melt cushion size, speed and pressure.â&#x20AC;? He elaborates, â&#x20AC;&#x153;The last factor to consider, and one that is often overlooked, is the quality inspection equipment. Buyers must verify whether the suppliers have the capability to measure micromoulded components. For visual inspection, a microscope (0â&#x20AC;&#x201C;50X) is needed. For firstpiece inspection, optical measurement inspection systems are suitable (0â&#x20AC;&#x201C;200X), which can handle most of the work. For in-process inspection, the micromoulder should have a camera inspection system incorporated in the injection moulding equipment. In combination with a robot,

the equipment continuously provides 100 per cent visual inspection. This ensures that the moulded component has been inspected and separated correctly from rejects. Otherwise, an operator would have to perform a manual in-process inspection.â&#x20AC;?

Future trends At present, micromoulding machines have plunger injection, programmable controls, built-in gate cutters and needle valves. Mahant avers, â&#x20AC;&#x153;In future, these machines will see new developments in the form of small screws (14-16 mm), high-speed injection up to 700-750 mm/sec, low injection volume and shot size of 1.0 gm or smaller and development of two-stage machines, ie, screw or plunger type.â&#x20AC;? He further adds, â&#x20AC;&#x153;The use of allelectric micromoulding machines for moulding electronic components offers various benefits along with precision and accuracy. These can lead to energy savings up to 80 per cent, helping to achieve accuracy and repeatability. In future, the machines will make use of tie bar-less mould-clamping structure, which will result in much larger mould space and can be equivalent to wide platen style. The machine will come with direct lock-ball screw with cross head to ensure accuracy and stable clamping and lead to equalised force on the mould. The machines will also incorporate mechanical ejector with servo control for enhancing machine efficiency.â&#x20AC;?

A positive outlook The increasing complexity of contemporary electronic appliances has resulted in more components per appliance. This has increased the pressure on injection moulders to constantly upgrade machines to meet specialised requirements. The added features demand more part strength and miniaturisation, which has increased the demand for micromoulding solutions. Due to various benefits offered by micromoulding solutions, their demand in moulding electronic compounds and in the E&E industry will continue to increase in the future.

â&#x20AC;&#x153;The demand for engineering plastics is continuously rising in the E&E sectorâ&#x20AC;? â&#x20AC;Śopines Dr Harindu Vyas, President (Technical & Development), Signet Industries Ltd. In a conversation with Avani Jain, he highlights the growth and demand for engineering plastics in the Electrical & Electronics (E&E) sector and underlines the recent trends & innovations making headway. How is the demand for engineering plastics in E&E sector?

What are the leading innovations in the sector?

Plastics in E&E applications cover the third largest plastics market in the world. Without plastics, some of the electronic or electrical applications would not be practically possible or be very expensive. In E&E applications, the contribution of thermoplastics is 75 per cent; thermoset, 15 per cent; polymer composite, 9 per cent; and others 1 per cent. Insulation is the most important property required by the material used in the E&E sector. The materials conventionally used for these applications are wood, ceramic composites, polymer composites and engineering plastics. Wood and ceramic composites have some drawbacks in comparison to engineering plastics, eg, high weight, brittle nature and high moisture absorption. To overcome these drawbacks, presently, manufacturers are using engineering plastics in the E&E industry. Thus, the demand for these plastics has increased. Also, engineering plastics are easily processable in injection moulding machines, with excellent flame resistance and dimensional stability. These have excellent electrical properties, eg, dielectric strength, insulation resistance, arc resistance, comparative tracking index, and properties for glow wire test & ball pressure test, etc. Thus, the demand of engineering plastics is continuously increasing in the E&E sector.

Research is underway to find new applications of engineering plastics in the E&E sector. Some of the leading innovations in this sector include nanofiller engineering plastic compounds to replace ceramics or thermoplastics in E&E applications, flame-retardant engineering plastics, high-dielectric strength polymer blends, etc. In Europe, Restriction of Hazardous Substances (RoHS) in electrical and electronic equipment and Waste Electrical and Electronic Equipment (WEEE) directives mandate that flame resistance be achieved without the use of halogenated components, one of the favoured areas of research.

What are the major usages of engineering plastics in E&E sector? Engineering plastics have wide applications in the E&E sector. These are used in electronic applications,

eg, CEE connectors, single-socket outlet, plug socket set, connection unit, Printed Circuit Board (PCB), electrical accessories, etc. Presently, engineering plastics are well accepted in optical cable application and its parts, microwave parts, switchgear application, telecommunication, low voltage application, etc. Electronic instruments used in medical diagnosis are unimaginable without using engineering plastics. Thus, the application of engineering plastics in the electronics sector is fast increasing.

What are the recent trends in the sector? The use of engineering plastics in the electronics sector includes PCB, switchgear applications, high-dielectric application, excellent arcing resistance, etc. Light-Emitting Diode (LED), which utilises engineering plastics, is one of the excellent innovations used across the world. Engineering plastics are also used in solar panels. Thus, almost 90 per cent of the E&E sector uses engineering plastics.

What are the future trends in engineering plastics in the E&E sector? Nano-plastic composite, clay composite, carbon fibre composite are the future of E&E sector. The demand for these materials will increase in the E&E sector, due to their numerous advantages. Depending on the electronics application, plastics is chosen for its rigidity or flexibility, toughness/durability, resistance to low or high voltage and electrical insulation or conductive properties. Ease of fabrication into complex shapes is also a requirement. Thus, in terms of usage of engineering plastics in the E&E sector, polycarbonate, acrylonitrile-butadiene-styrene, Nylon, thermoplastic polyester, polyphenylene oxide, fluoropolymers, polyacetal, polysulphones, etc, will be the future of this industry.

Polyolefins, on the other hand, have good hydrolysis properties with the ease of processing on standard plastic melt processing machines. In general, polyamides are observed to be incompatible with polyolefins. Therefore, polyamide alloy is a Polyamide (PA) 6- or PA66-based alloy with polyolefin, which offers the benefits of combined properties from polyamides and polyolefins. Orgalloy® – a type of polyamide alloy – is based on a patented technology, which ensures homogeneous mixing and ease of processing, combining the benefits of both polyolefins and polyamides. This technology also ensures consistency in the product, thus resulting in improved and consistent performance of the final product. Low moisture uptake resulting in retention of mechanical and electrical properties Excellent dimensional stability Easy to process on standard PA6 and Polyolefin processing machines incompatibles blend Good chemical resistance Low density

Good recyclability [Polypropylene (PP), Polyethylene (PE), PA, etc)] Light in weight as compared to PA6 and PA6/6; it is clearly visible to difference in density of these materials resulting in low-weight final component Excellent barrier properties against polar and non-polar gases and solvents

Multilayer film packaging A layered structure is usually used in multilayer film packaging for food items. Polyamide has been the material of choice for the barrier layer since long. In multilayer packaging, PA is often used when an enhanced barrier function is required, due to its unique combination of features: Mechanical strength Excellent impact, puncture resistance and tear resistance High transparency Thermal stability High oxygen barrier High aroma barrier

Easy thermoformability As a barrier material, PA does much more than just preventing oxygen migration into the package, which helps slows down spoiling or discolouration of the packaged material (eg, meat, cheese fruit juice packages). It also provides a barrier to aroma molecules, which helps prevent loss of aroma from the packaged material, as well as delays contamination of the package's environment by the aroma material. Some examples of packages where aroma conservation is necessary are spices, fruit juice, detergents, toothpaste, etc. Also, herbicides, pesticides and fungicides may require a barrier material, such as Nylon, to prevent migration of the active, potentially harmful ingredient as well as the organic solvent into the environment during storage. As an additional feature, a well-designed barrier material will not absorb flavour or aroma constituents from the packaged item.

solvents and gases (eg, hydrocarbons, oxygen), but, unlike polyolefins, these have poor barrier to polar solvents, eg, water and alcohol. Polyamide alloy combines the advantages of both polyolefins and polyamides, with simultaneous barrier to polar and non-polar solvents & gases. Another advantage of polyamide alloy is the ease of processing on machines designed for polyolefins. Polyamide alloy can be used to produce three-layer barrier films without using tie layer on the same machine designed for polyolefins, as polyamide alloy has good bonding with polyethylene. Polyamide alloy features good weldability at production speeds normally achieved with PE. Thus, the excellent barrier properties, mechanical properties, ease of processing and low sensitivity to moisture of polyamide alloy make it suitable for packaging applications such as cosmetics packaging, industrial packaging films, agricultural barrier films and food packaging films & containers.

Providing a unique barrier In the field of barrier packaging, polyamide alloy is a unique material that can bring about various changes without changing anything on one's standard machine. Apart from mechanical properties, low moisture pick-up and dimensional stability, this alloy has a lot to offer in packaging & films where low permeation properties are required. Ease of processing on standard extrusion and injection machines designed for polyolefins is an added advantage. Hence, polyamide alloy can be an ideal material for any application that demands barrier properties. July 2012 | Modern Plastics & Polymers

INSIGHT & OUTLOOK: Cost information in project management

Monitoring and regulating cost needs The previous two articles (Apr ’12 and June ’12) dealt with project cost control on the basis of the QRST pattern and the S-Curve & 4D Grid. This article focusses on cost information needs of project cost management. M Hariharan arious methods are used in management of project cost and schedule concerns. One of these is ‘Cost Information Need’. In cost management, there is only ‘A’ Cost, and no ‘The’ Cost, which depends on the requirement. Cost information requirements for a project may vary according to the stage of a project.

INSIGHT & OUTLOOK: Product grade transitions

Advantages of an automated approach Rising emphasis on productivity and safety in companies, particularly during crisis, has resulted in the need for an approach that could reduce energy consumption and enhance return on investment. Manufacturers, therefore, need to automate their processes and operations to attain these objectives as well as enhance productivity and profitability. Sunil Chaudhari

ypically, during a downturn, most processing companies tend to shift their priorities away from maximising throughput to minimising waste and reducing energy consumption as a means to increase return on investment. This change in focus thus leads to a stronger emphasis on the safety parameter. The experience of several polymer production plants is a case in point. In these plants, in particular, as also in other specialty chemicals facilities, processes are constantly changing, as they run on a fixed set of operating conditions. Companies continuously produce various products with different densities, viscosities and material properties. One of the key environmental challenges that organisations face is that each grade transition produces many tonnes of off-specification material. It is frequently difficult, or even impossible, to sell these intermediate grade products at a premium rate. While blending 74

Modern Plastics & Polymers | July 2012

and recycling techniques are available in this eventuality, which are more environment-friendly, these cost energy and such products thus manufactured will probably invariably have to be dumped into landfills. There are associated safety implications as well. Carrying out a transition from one product grade to another is one of the most safety-critical operations in a chemical plant.

A harmonised approach Until recently, no commercially available technologies were available to support automation and optimisation of product grade transitions. Minimising the waste created by the transition from one grade to another is something that Advanced Process Control (APC) can now help with, thanks to the innovative use of non-linear as opposed to linear control and advancements in procedural automation technology. Nevertheless, it is not only the development of the process that is important here, but equally important is orchestration of the functions of the

controller and having a technology that can coordinate and provide synchronised sequencing logic to some of the manual processes in the plant. For instance, AspenTechâ&#x20AC;&#x2122;s clients have witnessed considerable success in this area. We have been able to achieve an average of 50 per cent reduction in transition waste for them, with some clients significantly exceeding this value. This is a relatively recent but hugely significant breakthrough. Handing over the product grade transition process to an automated controller has never been taken lightly by operators who have historically not been fully convinced of the safety credentials of automated processes. Therefore, for many years, while APC was being widely deployed across ethylene and refining plants, it was not extensively used in the polymer industry. Since the collaboration was complex between what the automated controller needed to do and what operators were required to do, both on the plant and in the control room, it was not deemed safe to use the APC

Product grade transitions

technology. For instance, AspenTech has managed to tackle such problems by using a combination of sequencing technology and non-linear control. Over the past few years, the use of this method has become an expectation with companies in the sector. If a polymer company requires an advanced process control, then it expects the solution to optimise its product grade transitions. Polymer companies have moved on from being concerned only about the safety of handing over a process to a remote controller towards a situation where they recognise this as the right approach.

Working in tandem This paradigm shift has been driven by polymer companies themselves. In the earliest days of APC, vendors have tried to push a certain technology as being a solution rather than listening to their customers’ requirements. For example, they initially tried to promote the standard version of APC, though it did not work. Later, they shifted their focus to consider the viability of neural networks as a potential solution. Again, the sales pitch was unsuccessful, primarily because the ability of this technology to deliver precise predictions about product grade transitions can often be unreliable. Ultimately, vendors realised that the best approach was to work painstakingly with polymer companies in order to develop safe as well as reliable modelling and controller technology that closely fitted their business objectives of reducing waste not just in transitions, but also during in-grade product runs. Being able to manage this process has further environmental benefits because the ‘off-spec waste’ created by the latter process would either have to be reprocessed, with all attendant energy implications, or scrapped. The key was to gain knowledge and proofs of concepts and ensure that business needs were driving the technology development rather than vice versa.

Futuristic solutions This meticulous approach has ultimately borne fruit. Polymer companies today no longer have to be concerned about environmental and safety issues surrounding product grade transitions. They can now be confident about the resolution of the problems. Moreover, manual techniques combined with high-quality sequencing technology and non-linear controls have provided them with the solution that they have been seeking for many years.

AUTOMATION TRENDS: PC-based technology

Combining precision with cost-efficiency

Injection moulding is a widely used method for plastics processing and the technique & its applications have been refined over the years. Lionel Alva assesses how computer-aided technology has put the injection moulding process among the top techniques used in contemporary plastics manufacturing.

he advancements in computer technology and development of artificial intelligence has made it possible to greatly reduce the cost and lead times in the design & manufacture of injection moulds. This is due to the optimisation of the overall manufacturing process. However, understanding the intricacies of injection mould design is highly complex. This is because injection moulding imbibes several sub-designs related to various components of the mould, and thus needs an absolutely keen understanding of the overall manufacturing process.

Design considerations Mould design affects the productivity, mould maintenance cost, manufacturability of mould and quality of the moulded part. Until now, most of the work in mould design has been directed towards application of expert systems, knowledgebased systems and artificial intelligence to eliminate or supplement the vast amount 76

Modern Plastics & Polymers | July 2012

of human expertise required in the conventional design process. A number of studies have also been done on improving the design of specific components of an injection mould. The design principles of cavity layout and patterns of mould design can be presented easily in a knowledge-based design system. This helps build an effective system to address the complexities. Current practice for injection mould design, especially cavity layout design, depends largely on designersâ&#x20AC;&#x2122; experiences and knowledge. Therefore, one can use knowledge engineering, artificial intelligence and intelligent design techniques for generating accurately and efficiently an acceptable cavity layout design in an injection mould. The criteria to select a suitable layout pattern for design depend on working environments, conditions and requirements of customer and are based on a designerâ&#x20AC;&#x2122;s skills & experience. Intelligent design techniques should

be used in systems designed for such situations, especially for routine or innovative design. Design of an injection mould mainly involves considering the design of the certain elements or sub-systems such as mould type, number of cavities, runner system, ejector system, cooling system, venting and mounting mechanism. One cannot realistically expect a designer to keep close scrutiny on all design parameters. However, one must understand that cavity design and layout are the key factors affecting all other activities. Application of advanced knowledge based techniques to assist the designer in cavity layout and design enables effective creation and development of a capable computer-aided injection mould design & manufacturing system. â&#x20AC;&#x153;A fully integrated Enterprise Resource Planning (ERP) system should be used to enhance quality and consistency in production. Especially, in high-volume production, monitoring of

PC-based technology

In high-volume production, monitoring of the entire manufacturing process without the aid of technology is an arduous task. A keen understanding of various injection moulding parameters as well as a preand post-production analysis can help develop a highly effective ERP system.

the entire manufacturing process without the aid of technology is an arduous task. A keen understanding of various injection moulding parameters as well as a pre- and post-production analysis can help develop a highly effective ERP system,” avers Gaurav Bansal, Director, Kiran Consultants Pvt Ltd.

Challenges in India A key problem in India is investment, infrastructure and availability. The market is largely driven by Small and Medium Enterprises (SMEs) who do not possess the economies of scale that larger manufactures have. Thus, adoption of new technology becomes a major problem since it does not justify the return on investment for manufacturers. However, with recent technological developments, an ERP solution can be acquired at a much lower and affordable cost. This will greatly enhance the competitiveness of manufacturers in the Indian scenario. “In the Indian scenario, many SMEs view ERP systems as cost-prohibitive. Also, having an effective ERP system for the entire manufacturing process would require an approximate investment of ` 30-40 lakh, which many manufacturers are not willing to make. Better awareness is required regarding the advantages of ERP solutions, and it is important to consolidate the growth of the plastics industry in India. We also provide training to employees since a full-time operator is needed to monitor manufacturing activity,” observes Bansal.

Impact on quality A healthy mix of cutting-edge hardware and sophisticated software enables the creation of a highly integrated approach to injection moulding manufacturing. Since injection moulding is used for manufacturing of a wide variety of parts, the software must adapt easily to new applications. Further, optimisation of the material used ensures minimal wastage in various stages of production. Computer-assisted technology is designed to optimise the machinery parameters, including process stabilisation,

shortened cycle times and production efficiencies, which are most critical to zero-defect medical, automotive, electrical component, optical & liquid silicone rubber plastics injection moulding operations. Conventional injection moulding machinery optimisation involves time-consuming, manual trial-and-error adjustments of relevant parameters until all quality targets are met. During this phase, user experience with similar parts, materials and injection moulding machinery is critical. Online process optimisation (ie, during active production) is even more complex, as each parameter change can mean new machinery setting modifications, cycle time data recording and moulded parts measurements. “Our injection moulding systems consist of Programmable Logic Controllers (PLC), precise machining tools, temperature regulators and several highly advanced features that help in complete automation of the injection moulding process. While being an expensive proposition, the use of CAD has helped enhance the quality of our volume-driven manufacturing, while reducing energy costs,” avers Hiren Bhatt, Proprietor, Sai Shakti Plastotech.

Facilitating industry needs In the context of an injection moulding manufacturing facility, ERP may be used to facilitate on time delivery, eliminating unnecessary downtime, and ensure compliance with industry & government standards. A critical benefit is the ability to track and trace products across the supply chain. This is especially important for medical, safety and military applications. A product failure in the field can be isolated according to lot number and a replacement or repair can be pushed to all customers affected, thus allowing the manufacturer to proactively solve problems before they impact a large number of customers. Hence, in today’s fast-paced business environment, an ERP system is critical for the competitiveness of industries. Email: lionel.alva@infomedia18.in

ENERGY MANAGEMENT: Extrusion screw design

Energy savings through best-in-class processing An efficient screw design technology helps reduce considerably the energy consumed during the plastics extrusion process. With the industry continuously working on modifying the screw geometry and design, Avani Jain analyses the role and benefits of a good extrusion screw design technology in reducing energy consumption.

xtrusion can be seen as not only a final forming process, but also as an intermediate process for other processing techniques such as film blowing and injection & blow moulding. The efficient operation of extrusion screws used in the extruder is, therefore, the most essential aspect of the plastics processing industry, as these perform various tasks that enable manufacturers to achieve the desired results. Screws can be used for a plethora of applications such as conveying the polymer, mixing, shearing, compressing, degassing or heating the polymer through convection and many others. Jaymin Pithwa, Director, Konark Plastomech Pvt Ltd, notes, “For ensuring maximum energy efficiency, the machine designs have changed drastically over the years. Every company involved in plastics extrusion is trying to adopt strategies to produce maximum at a lesser energy cost. A good extrusion screw design technology can help achieve the objective of reducing the energy consumption to a large extent. Further, with each passing day, the companies are developing new technologies that can minimise mechanical losses.”

The core matter The extrusion process is highly dependent on electricity, and most of the energy used is directly related to machine operation. Various steps can be taken to reduce energy consumption of the extruder in plastic extrusion processes. The heart of the extruder is extruder screw. This is a long cylinder with a helical ﬂight wrapped around it. The screw is important because it mostly determines the conveying, heating, melting and mixing of the plastic materials. The stability of the process and quality of the extruded product depend on the screw design. The screw rotates in a cylinder that ﬁts closely around it. Extrusion screws perform four main functions – consistent feeding of the resin or axial forwarding, uniform melting of the resin, steady consistent

pumping of the melt and homogeneous mixing of the melt pool. Constraints like head pressure, throughput rate and product quality determine proper screw design for applications. These points must be considered while designing the extrusion screws.

Types of screws The field of extrusion screws has undergone tremendous development over the past decade. The screw used in extrusion processes can be classified in different ways. These can either be classified based on their methods of working or the functions they perform. Screws may also be classified based on the types of materials for which these are most suitable. Screws can be classified as single-stage or multi-stage (non- vented or vented) screws; simple

conveying screws or barrier screws or mixing screws and screws for lowviscosity polymers, medium viscosity polymers & high viscosity polymers. Some other modes of classifications could be single-flight or multi-flight screws; screws for smooth-bore extruders or grooved-feed extruders; screws for the primary extruder of foam extrusion lines and screws for the secondary extruder of foam extrusion lines (cooling screws). They may also be classified as melt-fed screws or plasticising (solid fed) screws. Barrier-type screw designs are most widely used in the extrusion industry and help in achieving energy efficiency. The advantages derived from well-designed barrier screws are improved rate, lower melt temperature and improved melt quality. Barrier screws, due to their mechanism of melting, produce higher internal pressures through the barrier section helping to increase the melting of material. In contrast, general-purpose screws do not produce as high internal pressures at the end of the transition section as do barrier screws. Primarily, barrier screws are designed so as to increase the throughput in single82

Modern Plastics & Polymers | July 2012

screw extruders and improve the melt quality. Twin screws also help in process optimisation. These are well known for their ability to offer optimisation, efficiency and flexibility in processing tasks such as mixing, compounding or reactions between polymeric materials.

Energy consumption A high percentage of the total energy requirement (up to 30 per cent) for moulding and extrusion equipment is used to plasticise material. Screw design is the most important feature on extrusion machines. Screw design technology is constantly evolving and the processors are always involved in gauging the appropriate screw diameter, geometry and length-to-diameter ratio appropriate to a specific material and plasticising rate. Energy savings of 20-30 per cent are claimed in some instances. If the rate of machine use is high and production demands are predictable, a screw replacement may be warranted. Screws and barrels should be checked every five to six months. Worn screws must be replaced or repaired as the payback is quick (ie, a few weeks).

Fixing the screw design Poor screw design is a common cause of overheating of plastics and is usually the reason why barrel cooling is needed. Operations where multiple extruder zones are cooled at 100 per cent are inherently inefficient. Pithwa notes, “The most energy-efficient extrusion operations are those where most of the heat is supplied by the extruder screw, with only a small amount of heating by the barrel and die heaters and without the need for cooling of the extruder.” The best solution to overheating caused by poor screw design is to change the screw geometry. If an extruder with poor screw design runs at 0.25 kWh/kg and with a good screw design at 0.20 kWh/kg, the energy savings will be $ 36,000/year at $ 0.10/kWh and a throughput of 1,000 kg/hr running 24 hr/day and 300 days/year. Thus, a

well-designed extruder screw can recover the costs faster. It also offers various benefits such as lower melt temperatures, less degradation of the plastics, better physical properties in the extruded product, better product appearance and consistency. Thus, irrespective of the age of the machine, it is essential to get the right extruder for the job and the screw diameter & design should be checked to ascertain that they are appropriate for the polymer product. Pithwa notes, “One must decide on the screw design and diameter right at the design stage. A well-designed extruder screw can cover up for the high prices relatively quickly, based only on reduced energy cost.”

The right design With energy management concerns rising worldwide, the companies in future will have to adopt various other measures for decreasing their energy consumption in plastics extrusion process. For this, the first step is to get the extruder right. If the extruder runs at optimum conditions, the need for downstream cooling and calibration will be minimised. To achieve this, deciding on the appropriate screw design right at the design stage will be beneficial. Thus, the companies need to increasingly adopt strategies to ensure a good screw design technology that helps minimise energy consumption. The ideal screws will fulfill the performance criterion to deliver maximum output for the available motor power with minimum frictional heat generation. Ideally, there should be no need for barrel cooling. These two criteria ensure that energy consumption remains at the lowest. These are only some of the steps for reducing energy consumption through extrusion screw design technology. But, a complete extrusion process has several other components that consume large amounts of energy, such as dryer, resin conveying system, water-cooling and circulation system. Various steps should be taken to reduce the energy consumption of these components as well. Email: avani.jain@infomedia18.in

POLICIES & REGULATIONS: Plastic waste management

Need for a holistic regulatory framework A growing population and vibrant economy brings with it the issue of increasing waste. Since plastic waste is considered hazardous to public health, Lionel Alva assesses the importance of having a strong regulatory framework to manage this waste.

he ability of India to become a major world player in all aspects depends greatly on how well it uses its most abundant resource – its population. The huge population of the country as well as the economic developments have created numerous issues, one of which is waste disposal – particularly non-biodegradable plastic waste. The emergence of supermarkets and mall culture has brought to the fore increasing utilisation and ubiquitous applications of plastics, right from packaging food stuff and electronics to automobiles & construction. Since any threat to public health must be viewed with urgency, there is a pertinent need to understand effective waste disposal methods to ensure sustainable and healthy growth in India.

Modern Plastics & Polymers | July 2012

Since the Indian industry is still in the initial stages of the retail and consumer revolution, it is possible to bring in a tenable policy and regulatory framework for the management of plastic waste. The most effective way to do this is to make a concerted effort at all levels, by including the Government, the plastics industry and even the consumers to some extent. Thus, there is a need to build better awareness and promote responsible behaviour on part of plastics manufacturers as well as those concerned with the plastics industry. With the help of an effective strategy, the country would be able to achieve a manufacturing consonance to ensure that the promise that this industry holds does not get affected. It would also lead to an amenable environment

for industrial growth, which is the need of the hour, considering India’s below average performance during this fiscal quarter.

Key challenges Plastic waste forms a significant part of the total Municipal Solid Waste (MSW). It is estimated that approximately 10,000 Tonne Per Day (TPD) of plastic waste is generated in the country, ie, 9 per cent of 1.20 lakh TPD of MSW. The plastic waste constitutes two major category of plastics – thermoplastics and thermoset plastics. Thermoplastics constitutes 80 per cent and thermoset, about 20 per cent of total post-consumer plastic waste generated in India. Thermoplastics are recyclable plastics, eg, Polyethylene Terephthalate (PET), Low-Density Polyethylene (LDPE), Polyvinyl Chloride (PVC), High-Density Polyethylene (HDPE), Polypropylene (PP) and Polystyrene (PS). Thermoset plastics are alkyd, epoxy, ester, melamine formaldehyde, phenolic formaldehyde, silicon, urea formaldehyde, polyurethane and metalised & multilayer plastics. The environmental hazards resulting from the mismanagement of plastic waste include the following aspects: Littered plastics spoils the beauty of cities and chokes drains, making public places filthy Burning of garbage containing plastics emits polluting gases and causes respiratory diseases Garbage mixed with plastics interferes in waste processing facilities and may cause difficulties in landfill operations Recycling industries operating in nonconforming areas result in unhygienic conditions

Plastic waste management

“In terms of post-consumer waste, especially with flexible packaging (eg, heavily printed, multilayer/laminated/ vacuum metalised pouches), currently, there is no efficient and professional waste disposal system in India. The challenges arise at various levels, since there are no sorting methods available at source, which results in waste disposed at an individual’s convenience,” avers Deepak V Mehta, Partner, Leevams Inc. He adds, “The advent of malls, super stores, mega stores, etc, in every city and town will further increase the use of convenient flexible packaging, while the waste disposal system will further deteriorate. Effective means of waste collection, disposal and recycling is the only resort to respect the growing consumption rates.”

Need for regulations Plastic waste is recycled in India in an unorganised way. Almost 60 per cent of the plastic waste collected and segregated is recycled back into materials for further processing into consumer products, while the remaining is left unutilised. Regulations and legislations are being enforced in two states of India, viz, Haryana and Himachal Pradesh, while a National Plastic Waste Management Council Task Force has been set up by the Ministry of Environment & Forests, Government of India, in association with Department of Petroleum and Chemicals, Ministry of Urban Affairs, Municipal Corporation of Delhi and various groups/associations of plastics manufacturers. There is scope for recycling/management of plastic waste as an organised activity in India. Mehta says, “Plastic Waste (Management and Handling) Rules, 2011, has certainly come into force; however, its understanding and implementation in the true sense will take time considering the diverse spread of the industry and huge population of the nation. The real effect can only be seen after the move is made in the right spirit and perspective.” At present, no penalties are imposed on plastics manufacturers for improper handling of plastic waste. This move would help improve the image of the plastics industry by making it more environmentally responsible, thus setting

a landmark precedent that would actually improve its prospects in India. The National Plastic Waste Management Council Task Force has recommended a strategy and action programme for Plastic Waste Management in India. The Ministry of Environment and Forests, Government of India, has issued criteria for labeling plastic products as environment-friendly under its ‘Ecomark’ Scheme, in association with the Bureau of Indian Standards (BIS). One of the requirements for plastic products is that the material used for packaging should be recyclable or biodegradable. The BIS has issued specific criteria for recycling of plastic waste while providing instructions on how waste should be classified and collected; further, there is a will and desire among Government bodies as well as Non-Government Organisations (NGOs) to make the existing guidelines stringent. However, while formulating Indian standard specifications for various plastic products used for critical applications such as plastic piping system, water-storage tanks and packaging for food articles, a clause is included, which reads – ‘No recycled plastic waste shall be used’. The Ministry of Environment and Forest in association with BIS has carried out an exercise to include the use of recycled plastic waste where appropriate in the manufacture of plastic products, and this should be specified accordingly in the relevant Indian waste disposal guidelines.

Plastic Waste (Management and Handling) Rules, 2011, has certainly come into force; however, its understanding and implementation in the true sense will take time considering the diverse spread of the industry and huge population of the nation. Deepak V Mehta Partner, Leevams Inc

Preventing wastage Plastic waste has several facets involving various stages where waste occurs, and it is important to bring about an effective strategy to deal with different types of waste. Recycled polymers are finding new avenues for application. If the waste is not handled in an effective manner, then it could lead to a serious situation. The implications of bringing in better regulations would ensure that plastics manufacturers utilise waste in a proper manner. Alternative strategies such as the use of non-recyclable waste for roads and power generation can also be explored, which could lead to innovative methods for waste management while enhancing the prospects for the industry in the global arena.

STRATEGY: Operator-friendly machines

An imperative for reducing labour costs With growing emphasis on automation and demand for operatorfriendly machines in the plastics processing segment, many companies in the country are employing machines with PC-based automation or control systems. Avani Jain finds out how the use of such machines helps in reducing the labour costs.

he Indian plastics processing machinery industry is incessantly setting up new highs year over year, due to the enhanced ability of Indian machinery suppliers to accommodate innovative technology. Evolved over the years, the plastics processing industry has seen some major innovations recently, which have a long-term impact on the functioning of machines. With overall cost reduction including labour costs and quality improvement as the main driving forces, the plastics processing industry offers a comprehensive choice of technologies and application techniques. Some of the major trends for increasing the operating efficiency and reducing costs in all sectors of the plastics processing machinery segment such as injection moulding, blow moulding and extrusion include the use of Supervisory Control And Data Acquisition (SCADA) system, Programmable Logic Controller (PLC) and PC-based control systems. Location courtesy: Parikh Packaging Pvt Ltd Praveen Sharma, Proprietor, Photo: Aamir Quadri Hind Machineries, notes, “Today, customers want highly automatic and synchronised systems to improve their product quality & efficiency and reduce overall costs. Although priced slightly higher, these machines are high in demand, as they help reduce the overhead cost of manufacturers, thus eliminating the need to employ a large number of workers to perform common tasks.” 88

User-friendly machinery The main aim of the control system for any equipment in the plastics industry is to provide a simple, but powerful user interface. Its function must be intuitive and easy-to-use; further, depending on the familiarity level of the user, the complexity of the functions can increase. Currently, machines with PC-based control systems are the most operator-friendly machines available in the market. PC-based automation includes a PC platform with Windows operating system. It ensures a host of benefits to the plastics industry, ranging from higher quality parts, through improved equipment uptime, faster cycle time and more predictable production flow to reduce employee turnover. A PC-based system solution offers a style of operation similar to desktop PC applications, which any individual can use today. This has a direct impact on the humanoperator performance considering the rules of behavioural science. Further, software such as colourful Graphical User Interface (GUI) can be installed on PCs, which not only makes machine operations interesting and motivating for operators, but also shortens the learning curve for them. Thus, machine operations become more enjoyable at the shopfloor.

Controllers speak In a PC-based system, at the press of a button, the set-up person can select a completely different procedure or adopt its function to the required procedure. The ‘simple view’ wide selections of tried-and-tested standard procedures are available to the operator in the controller for different automation applications. The set-up person does not require any programming knowhow; he/she can simply select a procedure and adopt the process sequences to the requirements demanded by changing variants. All the settings necessary for a sequence (position, speed

movement sequences for linear robots can thus learn to program articulated arm robots within minimum time. Thus, all tasks can be performed by just clicking the button, reducing the need of labour for performing each task manually.

Although priced slightly higher, these machines are high in demand, as these help reduce the overhead cost of companies, thus eliminating the need to employ a large number of workers to perform the tasks. Praveen Sharma Proprietor, Hind Machineries

and time) are displayed on a clearly arranged setting page. Commands to be inserted are simply selected from an extensive functions list and placed at the desired point in the sequence. Pressing the symbols in the sequence editor immediately calls up the respective screen page on which the parameters can be set. Even complex sequences can be quickly configured. An operator able to create

The ‘soft’ware touch One of the key benefits of process control system based on PC technology is ease of use because the software is running on a familiar platform, and that makes it cost-effective as well. An operator can be trained to use a well-designed touchscreen control system in a few hours. And because these systems are software based, these are more powerful and flexible. PC-based systems are inherently user-friendly and operation can be very intuitive. The biggest convenience for users is the ability to see the ‘big picture.’ Instead of viewing process conditions in isolation, this type of system allows users to readily view data from all equipment from a single, central monitoring station and view that data over time via trending screens.

Human Machine Interface (HMI) Today, machines with PC-based controls come equipped with HMI, which is operator-friendly and easily accessible for process parameters. It provides excellent troubleshooting guidelines, along with the help and alarm menu pages. It has several features: functionally oriented screen

layouts; process parameter monitoring in real-time and feeding value on absolute basis; simple & pictorial diagrams to enable operator understanding; auto temperature and profile selection for homogenous melt from the first shot; extruder over-run for uninterrupted auto cycle; auto heating start, shut down and standby to save time & energy during operation; intrusion insert moulding, gasassisted interface, core pulling, etc for multitasking utilisation; auto purging for smooth shutdown; mould cooling, mould gate option, sprue break, nozzle shut-off valve, cold slug remove, etc for various applications; as well as smart input/output for uninterrupted production.

Reducing labour dependence At present, the controls use microprocessor-controlled high-speed PLC systems, which also help reduce labour cost. Sharma says, “The PLC systems help in reducing labour costs to a large extent, as only one skilled personnel is required to set the parameter once and then the operations can be repeated automatically, thereby minimising manual labour.” Hence, machines with PC-based controls can reduce the labour cost of the company considerably.

Future trends The plastics processing industry is in the midst of a transformation in terms of machine construction and system engineering, leading to development of versatile and innovative control technology. Further, despite increasing complexity, the user-friendliness of the systems and processes not only need to be maintained, but also improved. The operator must only be confronted with a central operating concept and user interface. Therefore, control systems that facilitate integration of peripherals, a uniform operating concept, simple programming and clear representation of complex processes with all important parameters, a high degree of process reliability and comprehensive motoring functions for quality assurance are required to increase the user-friendliness of the machine, which, in turn, will lead to reduction of labour costs.

TIPS & TRICKS: Mould maintenance

Steps to a

healthy machine life Regular maintenance can prolong a mouldâ&#x20AC;&#x2122;s life, reduce interruptions, and hence save time, money and problems in the long run. Anwesh Koley lists some pointers that are a must for ensuring proper functioning of plastics machinery through regular maintenance of moulds.

lastics moulding machinery are the most important of all processing equipment, as mould quality is directly related to the merits of the quality of products. Moreover, as the importance

of the mould during the processing of plastics is high and involves a high cost to the company, these should be paid special attention. Therefore, it is important to spruce up the quality of moulds as well as

their maintenance in order to increase the life of the machinery and ensure seamless output quality. Email: anwesh.koley@infomedia18.in With inputs from: Gaurav Anand, Director, AB Diachem Systems Pvt Ltd

Following are some of the pointers for ensuring regular mould maintenance:

In-house tool abuse should be reduced by having a clean operation using well maintained machines and the right tools. One should avoid the use of hard tools such as screw drivers, hammers, punches and knives on any moulding surface, parting or shutoff surface. Use soft tooling like rubber mallets, punches and pliers made from plastics, copper or brass to avoid damaging the mould.

Aluminium or soft tools suffer wear and tear faster than tools made of steel. Plastic materials having fillers are abrasive and wash away the mould steel after some cycles. Plastics with high melt temperature expose the mould to more heat and increase wear. Some materials emit excess residue or corrosive gasses, resulting in the need for regular mould cleaning.

Preventive maintenance should be done every time the mould goes into operation and every time it comes out of the press. Inspection must note small problems and have the repair done. This type of maintenance should be performed by a lead operator in the tool room after about 20,000 cycles, 10 production days or at the end of a production run, whichever comes first.

Use soft or treated water in cooling systems. Blowing out or draining the tool when it is pulled from the machine will enhance its life. Avoid excessive clamp pressures, high injection pressures and over-packing or flashing the mould. The press should not be operated such that the mould is rapidly jerked open and closed, and the appropriate components should be well lubricated.

Extreme care should be taken not to crash the mould closed or close up on partially ejected parts. Seal the work area and mould storage area from the external environment. Moulds with intricate mechanisms or parts requiring unusually high tolerances will require more maintenance than a simple open-and-shut mould, making a low tolerance part.

All components determined and authorised to be replaced should be removed and new components constructed and installed in accordance to the original designs, if previously certified spare components are not available. Worn leader pins, bushings and all bearing moving surfaces such as wear plates and wedge blocks, should be checked for wear and replaced or repaired as required.

BOOK REVIEW

EPOXY POLYMERS Editors : Jean-Pierre Pascault and Roberto J J Williams Price : ` 6,595

Epoxy polymers are considered as mature polymers since the fundamental knowledge of these thermosetting polymers has been well established during the 1970s and 1980s. The industry, however, continued developing new formulations, processing techniques and applications in the areas of adhesives, coatings & composites, which extend to sectors such as building, electronics, sports goods, automobile and aircraft among others. Towards the end of 1990s, the world had begun to recognise the word â&#x20AC;&#x2DC;nanoâ&#x20AC;&#x2122;, and this book covers the new work done with nanoclays, Polyhedral Oligomeric Silsesquioxanes (POSS), block co-polymers and carbon nanotubes. Serious readers from the industry and students can benefit from this exhaustive compilation. The book has a chapter on â&#x20AC;&#x2DC;Green Chemistryâ&#x20AC;&#x2122; describing different monomers derived from various natural products that are now available commercially. It also has a chapter on thermoplastic epoxies, which can be processed like thermoplastics and cured like thermosets. There is a good inclusion of advanced functional materials such as self-healing, shape memory and transparent opaque transitions with formulations based on epoxy polymers.

PLASTICS AND RESIN COMPOSITIONS Editor : W Gordon Simpson Price : ` 7,275

Polymers are the building blocks of a vast number of natural and synthetic raw materials, which when mixed together and with other materials produce a variety of products such as plastics and resin-based articles, adhesives and many other coating formulations. Three basic mechanisms, either alone or in combination, can be present in mixing processes. This book briefly describes the mixing equipment and the process where mixing is achieved by a combination of shear and circulation. Blade mixers achieve the mixing by kneading the material continuously, tearing, folding and compressing it between heavy rotating blades. The blades are available in various designs, but are commonly Z-shaped, and while rotating their paths, overlap or cross to achieve the required degree of mixing. The book gives a view of high-pressure laminates, which play an important role in engineering industries. Other important features include in great detail the high-pressure laminates and copper-clad laminates that are used as printed circuit boards. The topics covered at length in this book are remarkable, such as the use of paints, additives such as anti-oxidant, surfactants, anti-foams, fungicides and curing catalysts. This book is excellent for the library for general information on plastics and resin compositions and even demands space on the shelf of industries even remotely related.

PRODUCT S

Water heater

Air-cooled compressor

The model STM-MW water heater is used to heat up the mould and maintain constant temperature. High-temperature water from the mould is returned to the cooling tank and cooled by direct cooling. It is then pressurised by the high-pressure pump, sent to the heating tank and, finally, to the mould with a constant temperature. The water heater adopts magnetic pump instead of mechanical pump to reduce the leakage of media water. It employs brand new controller, which ensures stable temperature controlling and abundant expandable function.

A unique range of air-cooled compressors is offered for industries that demand oil-free air at their application point. The non-lubricated compressor offers advantages of low energy consumption and low running costs. The aircooled design eliminates the need for water cooling systems, thereby saving industrial water costs. Two-stage air-cooled aftercooler has a 0.25 kW single-phase motor driving a cooling fan.This eliminates the need for cooling towers, water circulation pumps and the associated piping, thus reducing the initial investment. This also reduces the installed power.
