FROM THE PUBLISHER

SUSAN GIBSON JSJ Productions, Inc.

What’s Coming?

There is a list of world-changing technology advances coming soon. Augmented Reality (AR) is poised to be a major tech trend, further integrating into consumer and enterprise applications. With the evolution of hardware, such as advanced AR glasses and improvements in mobile devices, AR will offer more immersive, interactive experiences.

The hot list of coming advances includes ways Artificial Intelligence (AI) is accelerating scientific research with a focus on applications in health, communication, infrastructure, and sustainability...and yes, manufacturing. We already know AI will play an integral role in the future of plastics manufacturing.

There was much information on the topic of AI shared at Rotoplas 2024. Patrick Swerdtfeger, in his keynote address, electrified the audience with his projections for the near-term reporting that we will see significant changes in the next 18-24 months. Some of the changes he cited included how we will get around. Tesla is on the cutting edge of offering autonomous cars that we’ll use like a cab and personal robots we’ll use to manage our houses and yards. Credit reports will be based on all new criterion like how charged up your mobile phone is and how accountable we are to daily functions rather than the years-old 3 bureau reporting system. According to Swerdtfeger, AI will replace jobs like customer

service, marketing, creative, design, software coding, and language translations, to mention a few. If applied, AI technology may substantially replace labor in manufacturing plants. He used the analogy of “thinking like an orchestra conductor using these tools as your employees.” He really stirred up my thinking and made me realize we had better get ready for these changes now.

“WE ALREADY KNOW AI WILL PLAY AN INTEGRAL ROLE IN THE FUTURE OF PLASTICS MANUFACTURING.” You’ll find some significant pearls of information inside including things like Transparency Market Research’s projections for the future of rotomolded fuel tanks made of acetal due to the limitations on PFAS, and the projected 5.9% growth for the rotomolding industry by the end of 2031; evidence that rotomolding associations are seeing increased attendance at their annual conferences, which bodes well for industry growth; Ian Hansen’s report on our increasing globalized business environment and how companies that expand their reach beyond borders are often finding themselves at a competitive advantage. There is so

much more so don’t skip a page!

Congratulations to ARM for such an exciting and productive 2024 Meeting and Rotoplas! It was one of the best. Congratulations to ARMA for their highly successful and memorable Rototour in Brazil (read Michelle Rose’s article inside).

Rotomolding Offers Distinct Advantages for Manufacturing Parts Used in Cleaning Robot ZHONGSHAN CITY, GUANGDONG, CHINA – Rotomolded parts are widely used in the manufacturing of cleaning robots, significantly enhancing their functionality and durability. The rotomolding process, renowned for its capability to fabricate intricate, hollow structures with consistent wall thickness, offers distinct advantages in crafting cleaning robot parts that demand both structural robustness and resistance to chemical exposure and physical impacts.

Advantages of Rotomolding for Cleaning Robot Parts 1.

3.

4.

5.

6.

7.

8.

Complex Geometries: Rotomolding can easily produce parts with complex shapes and undercuts, which are difficult or impossible to achieve with other plastic manufacturing techniques.

Durability: The process naturally produces stress-free parts due to the slow and controlled cooling phase, leading to increased durability and impact resistance.

Customization: Rotomolding allows for easy color changes and the integration of different types of plastics or additives for UV protection, flame retardancy, or improved impact strength.

Low Tooling Costs: Compared to other processes like injection molding, the tooling costs for rotomolding are relatively low, making it costeffective for lower production volumes or custom designs.

No Seams or Joints: Since the parts are formed in a single piece, there are no seams or joints, which reduces the risk of leaks or breaks.

Uniform Wall Thickness: Rotomolding ensures consistent wall thickness throughout the part, which is critical for the performance and durability of cleaning robot components.

Design Flexibility: Design modifications can be easily implemented since the molds are relatively simple and inexpensive to alter.

Corrosion Resistance: The plastics used in rotomolding, commonly polyethylene or polypropylene, offer excellent chemical resistance, making the parts suitable for harsh cleaning environments.

18 ROTOWORLD® ISSUE 5 • 2024

9.

Maintenance and Repair: In the event of damage, rotomolded parts are often easier to repair than parts made by other processes.

10. Weight Control: The process allows for precise control over part weight, which is crucial for cleaning robots where every gram counts in maintaining efficiency.

Applications in Cleaning Robots

• Housings: The main body of the cleaning robots, which encloses electronics and motors, providing protection from liquids and dust.

• Battery Compartments: Lightweight and secure enclosures for battery packs.

• Handles and Grips: Ergonomic designs for comfortable operation by users.

• Access Panels: Easy to open and close, allowing for maintenance and access to internal components.

• Fluid Tanks: For storing cleaning solutions, requiring no leaks and good chemical resistance.

• Wheels and Casters: Durable wheels that can handle the weight of the robot and the rough surfaces it encounters.

• Sensor Enclosures: Waterproof and dustproof cases for sensors and cameras.

• Filter Housings: Used in air purification systems integrated into some cleaning robots.

• Spray Nozzles and Tubing: For evenly distributing cleaning fluids.

• Agitators and Brushes: Components for scrubbing and cleaning surfaces.

• Bumpers and Guards: To protect the machine from damage during operation and collisions.

Here at Light Venus, we offer custom rotomolding services for both OEM and ODM customers worldwide, producing a wide range of enclosures and parts for the cleaning robot industry. We warmly invite you to inquire about our custom solutions for your specific projects.

PFAS at a Glance: Challenges and Industry Impacts VICTORIA, TX, USA – The Society of Plastics Engineers (SPE) recently hosted its annual event in Baltimore, bringing together over 150 professionals focused on the pressing issue of PFAS (Per- and polyfluoroalkyl substances).

This year’s event addressed critical topics, including legislation, PFAS characterization, and alternatives for PFAS-free solutions, highlighting the challenges facing the plastics industry as it adapts to evolving regulations.

Understanding the PFAS Challenge

One of the significant challenges for the plastics industry lies in the upcoming restrictions on PFAS compounds, especially in specialty applications where PFAS materials play essential roles. PFAS compounds consist of a carbon chain—either straight or branched—in which one or more carbon atoms are partially or fully fluorinated. While the scientific community has acknowledged that not all PFAS compounds have identical properties and risks, current legislative momentum may not reflect this nuanced understanding. Consequently, products like PTFE (polytetrafluoroethylene), which is also classified as PFAS, could soon be restricted in many applications.

everyday products. One of the FDA’s recent priorities includes phasing out PFAS-based grease-proofing agents used in paper and cardboard products.

This action aligns with broader public health goals to reduce human exposure to PFAS, particularly in consumer products that may come into direct contact with food.

Looking Ahead in Plastics Engineering

Plastics Engineering magazine will publish a series of articles to dive deeper into PFAS-related topics in the U.S. and Canada. This coverage will explore further details about the evolving regulations, detection challenges, and industry solutions as companies work to align with sustainable practices. By addressing these pressing issues, the magazine aims to support the industry’s transition to safer, PFAS-free materials while helping stakeholders stay informed on critical regulatory and scientific developments.

For more information, go to www.spe.org. R

Complexities in PFAS Detection

A key concern discussed at the event was the complexity of detecting PFAS compounds accurately.

As speakers pointed out, existing detection methods face notable limitations. For instance, the “total fluorine” detection method measures fluorine levels without identifying the source, which can lead to results that include fluorine from non-PFAS compounds. Alternatively, targeted analysis requires specific characterization methods for individual PFAS compounds, but standardized methods for many of the PFAS in existence remain insufficient.

This detection gap poses a significant challenge as companies strive to meet new regulatory requirements without the full ability to identify PFAS presence reliably.

igus® Introduces New Environmentally Friendly PFAS- and PTFE-Free Bearing Material igus® announces it has developed a new polymer bearing material called iglide® JPF that is free of both per- and polyfluoroalkyl substances (PFAS) and polytetrafluoroethylene (PTFE). This innovation marks an important step in the company’s efforts to create sustainable alternatives to conventional plain bearings.

Due to their water, heat, and dirt resistance, PFAS and PTFE are key materials in the production of self-lubricating plain bearings in a variety of industries.

However, PFAS degrade slowly, posing risks to both human health and the environment.

“USERS WHO HAVE RELIED ON IGLIDE J FOR THEIR MACHINES AND SYSTEMS CAN NOW OPT FOR A PTFE-FREE ALTERNATIVE WITH EQUIVALENT PERFORMANCE.” — Lars Butenschon, head of the iglide Plain Bearing Technology Business Unit igus ® has developed iglide JPF, a new self-lubricating plain bearing material without PFAS. (Source: igus GmbH)

Addressing these concerns, iglide® JPF is a plain bearing material delivering high wear resistance and durability without the use of PFAS or PTFE. This dryrunning, wear-resistant polymer offers comparable friction and wear performance to iglide® J, and its development is a response to growing global regulatory pressures to limit the use of harmful substances in industrial and consumer products.

“From the onset of the discussions about a potential PFAS ban in Europe, we prioritized the research and development of alternative materials,” said Dr. Magnus Orth, Head of the igus® Material Center. “Our inhouse material development and compounding capabilities enable us to quickly respond to regulatory changes and offer new solutions that meet market demands.”

“Users who have relied on iglide J for their

22 ROTOWORLD® ISSUE 5 • 2024

machines and systems can now opt for a PTFEfree alternative with equivalent performance,” said Lars Butenschön, Head of the iglide Plain Bearing Technology Business Unit. “Our goal is to transition our standard materials to PTFE-free formulations. We are already in the process of developing alternatives for materials such as iglide X and iglide W300, and early test results have been very promising.”

With the launch of iglide® JPF, igus® is reinforcing its commitment to developing sustainable products that comply with the latest regulatory standards. As igus® continues to innovate, it remains focused on providing high-performance solutions that reduce their environmental impact and meet the evolving needs of igus® customers.

2024 ROTOTOUR GOES TO BRAZIL MICHELLE ROSE, ARMA CEO

24 ROTOWORLD® ISSUE 5 4 • 2024

I’ll be honest—Brazil wasn’t exactly at the top of my travel list.

In fact, as the trip approached, I wasn’t really looking forward to it at all. It’s not the best way to start a travel article, I know, but it’s the truth! The good news is, I’m always happy to admit when I’m wrong—and wow, was I wrong!

From the moment we touched down, Brazil completely blew me away. The country is vibrant, beautiful, and full of life, and the people we met were incredibly friendly and welcoming. One of the best things about our Rototours is that we don’t just stick to the usual tourist hotspots. We get to experience places that many travellers wouldn’t see—small cities, regional areas—and it’s in these places that you really get a feel for the heart of a country.

Every one of us left Brazil with a deep appreciation for the generosity of its people.

Our adventure began in Salvador, Bahia, a region known for its stunning beaches and endless sunshine. It was also where we were introduced to one of Brazil’s national treasures: the Caipirinha. This iconic cocktail, made with cachaça, sugar, lime, and ice, quickly became a favourite among our group. It’s easy to see why it’s not just a popular drink in Brazil, but also loved internationally—there’s nothing quite like sipping on a Caipirinha while soaking up the Brazilian sun!

From Salvador, we made our way to our first factory visit—FORTLEV. Now, I knew FORTLEV was a big player in the rotomoulding world, but nothing could have prepared me for the sheer size of their 170,000 sqm site. Driving past their vast yard,

We were greeted like old friends, with a line of staff and welcome signs—hugs all around! FORTLEV has been a long-time member of ARMA and a supporter of Rototour for over a decade, so it was exciting to see firsthand what they’ve achieved.

After a company introduction, we split into groups for a tour of the facility, which took a whopping three hours—yes, it’s that big.

Once we regrouped, we enjoyed a delicious lunch before heading off to our next destination—Rio de Janeiro!

Rio greeted us with open

arms, and our first stop was a Brazilian BBQ at the beautiful Assador Restaurant, right on the water’s edge. We dined outside, basking in the sunshine and gazing up at the iconic Sugarloaf Mountain. Our guide gave us some pro tips on how to make the most of a Brazilian BBQ, and we enthusiastically sampled multiple local meat dishes until we were absolutely stuffed. After lunch, we took the famous cable car up Sugarloaf Mountain, where we enjoyed breathtaking views and, of course, a cocktail to top off the day. Our evening ended at the world-renowned Copacabana Beach, where some attendees explored, while others took the chance to relax after a busy day.

The next morning, we were up bright and early for another action-packed day. Our first stop was Christ the Redeemer, one of the most iconic landmarks in the world. Standing at the base of this massive statue, looking out over Rio, was a truly awe-inspiring moment. From there, we made our way to the samba school district for a bit of Carnivale magic. We got a behind-the-scenes look at the set designs, tried on elaborate costumes, and even took a samba dance lesson! Our lunch stop was at the famous Casa de Feijoada, where we sampled Brazil’s national dish. While feijoada wasn’t to everyone’s taste, it was still an experience we’ll never forget.

Our whirlwind stop in Rio ended far too quickly, and before we knew it, we were on our way to São Paulo. The floods earlier this year had forced us to make a few changes to our factory visits, but FORTLEV kindly offered to host us again at their Itatiba site. We

“ROTOTOUR BRAZIL WAS MADE POSSIBLE BY OUR PARTNERSHIP WITH BRASKEM” were treated to a traditional lunch at a local restaurant, and it was here that we all became very familiar with Google Translate and ChatGPT, helping us bridge the language gap with the locals. The highlight of this visit was when FORTLEV’s President personally thanked ARMA and Rototour for our support in helping them grow into the industry leader they are today. It’s moments like this that remind us just how impactful our work can be.

After saying our goodbyes to FORTLEV, we headed to Rotosynergy, a relatively new company that was born from the collaboration of three different Carnivale Experience in Rio!

businesses. Despite only being in operation since 2018, they’ve made impressive strides and were more than happy to show us around. We had free reign of the facility, including their latest machine installations, and we left feeling inspired by their growth and plans for the future.

Our day ended with yet another mouth-watering BBQ—Brazilian hospitality really knows no bounds!

The next morning, we packed up and set off for Aqualimp, a company that has made waves in the industry since its founding in 2001. Originally from Mexico, Aqualimp has expanded its operations to Brazil, and it was clear from our visit that they’re constantly pushing the boundaries of innovation.

From there, we flew to Chapecó, where Rotoline hosted us for a lovely dinner. Although they weren’t officially part of the tour, we couldn’t resist the opportunity to make a quick stop at their factory. The vote among

the attendees was unanimous— everyone wanted to see what Rotoline had to offer. It may have been our fastest factory tour yet, but it was enough to give us a glimpse into their incredible impact on the Brazilian rotomoulding industry. Their machines are widely used across the country, and it’s clear that they’re seen as partners by many within the industry.

The tour continued with visits to Rotoplastyc and Tecnotri.

Rotoplastyc impressed us with their innovative products and well-organised factory layout.

One thing we noticed in Brazil that’s not common in many other countries was the large employee canteens, where three meals a day are provided. We were treated to a traditional BBQ, complete with a chef cooking outside while we enjoyed our meal inside.

At Tecnotri, we were welcomed

like old friends and treated to an unforgettable evening of live music, dancing, and plenty of food and drinks. It was one of the best nights of the tour, and I had a hard time convincing everyone to get back on the bus, knowing we had an early start the next day.

After an early breakfast and a 6am departure, we embarked on a four-hour drive to Braskem’s Technology Centre. A special thanks to Eliomar Pimenta and the Braskem team, who not only helped us coordinate the entire tour but also joined us on the bus to assist with the logistics.

Braskem is Brazil’s leading resin supplier, and their labs and pilot plants were nothing short of impressive. We also spent time at their Rotomoulding Research Centre, where they’ve installed a Rotoline machine.

Our final factory visit in Brazil was at Resiplastic. In a unique

twist, they set up our introduction session right in the factory, and we were free to explore the facility at our own pace. The staff were eager to share their knowledge, and the attendees left with notebooks full of ideas and inspiration.

After a quick refresh back at the hotel, we enjoyed dinner in Brazil at a local pub with live music—a perfect way to cap off an incredible journey.

The next day, we flew back to São Paulo for dinner at the Skye Restaurant, where we said our goodbyes to those not joining us for the next leg of the tour to Rotoplas in Chicago. For those continuing on, we made sure to take care of our attendees with access to the United lounge, where they could relax, shower, and even enjoy a massage before boarding our flight.

In Chicago, we settled in for a

with acrobats, strongmen, and comedians. It was a night full of laughter and a fitting end to an incredible journey.

The next day, we visited Royal Basket Trucks and Plasticraft as part of Rotoplas, with attendees

raving about the factory tours. We wrapped up the tour with a few more dinners, including plenty of Chicago’s famous deep-dish pizza.

Rototour Brazil 2024 brought together 23 attendees from 10 different countries, and on behalf of everyone, I’d like to extend my heartfelt thanks to the factories and companies that hosted us.

Your hospitality and willingness to share your knowledge made this tour unforgettable.

scope of the industry’s reach. It facilitates automotive, marine, medical, leisure, agriculture, and technology sectors along with countless others. While many Rotomolded products are beautiful in their own right, others are truly works of art, noting the Tulip chairs in urban Holland, the Swirly Top chairs in Mid-Town Manhattan, and the Giraffe in Love in Italy. Rotomolded products are in factories, businesses, high end hotels, and the homes of celebrities. But above all of that, “This is an industry that matters,” she said. “It is an industry of

stability and possibility,” she said.

Gibson ended with saying, “It is my hope that our industry magazine has in some meaningful way, blessed you, your company, your career, and your products.

It has been my pleasure to raise the profile and showcase the capability of a simply amazing industry.”

Martin Coles

Martin Coles joined the global Rotomolding industry in the 1980s working for the Italian Polyethylene producer EniChem.

For the last 38 years, he has championed the process and the industry. He founded Matrix Polymers in the UK with fellow Hall of Famer Dr Nick Henwood 32 years ago. Today the company is one of the largest material suppliers in the world dedicated solely to Rotomolding, with six

manufacturing sites located across three continents and more than 250 employees. Martin presents at conferences in Europe, Asia, Africa, Australia, and the US. He and his staff frequently provide workshops at conferences and open-day forums at multiple facilities to demonstrate new technology and progress in the industry. He is a Contributing Editor to RotoWorld®, writing articles focused on energy efficiency, developing young talent to support the future, and how the benefits of the process can be more broadly used. He has also sparked the industry to respond more aggressively to the issues of recycling, plastic pollution, and environmental impact.

Driven by a deeply held purpose of promoting the industry and putting major resources from his company behind it, he is a genuine ambassador for the rotomolding

industry worldwide.

In his acceptance speech, Coles said that he felt humbled to receive such a prestigious award and thanked ARM. He also paid tribute to fellow Hall of Famer Dr Nick Henwood, with whom he co-founded Matrix Polymers 32 years ago, with the ambition to build a polymer supply company that was fully focused on Rotational Molding materials.

Coles then went on to say that Matrix has been successful and has been able to grow into a global supplier with 6 compounding and pulverizing plants around the world. This means as CEO he is fortunate to travel and have the opportunity to gain a unique insight into the Rotomolding industry in different parts of the world.

Coles said that most issues facing the industry are common across the world, but the urgency

www.rotoworldmag.com 33

Martin Coles and Dr Paul Nugent

to address these varied depending on the region.

A key concern he sees is the long-term sustainability of the Rotomolding process, with major challenges in several areas. The first one he highlighted was the very high energy consumption and the poor efficiency of the process, with typically only 5-8% of the energy used being converted into making the actual part. He mentioned the importance of developing technology, which significantly reduces the amount of energy needed. He said he is particularly excited to learn about work being done to develop lowcost solutions using electrically heated molds. This technology could also potentially revolutionize the process and open the use of different polymers.

Pollution and problems with plastic in the environment was the

34 ROTOWORLD® ISSUE 5 • 2024

next issue Coles mentioned, which is a global issue. He implored the audience to sign up to Operation Clean Sweep. His message was that we all must take responsibly and “do our bit”.

Finally, Coles highlighted the issue of recycling and reuse of polymers in the Rotomolding sector. He said that there was big confusion about what we mean by recycled materials, with some molders believing that reprocessed production waste from scrap parts and off-cuts could be described as recycle.

Coles stated that the average person on the street would likely not perceive it as recycling.

They would expect claims about parts being made from recycled materials to align with their common understanding of the term.

Coles suggested that ARM

and the other Rotomolding associations around the world should get together and create some clear definitions and standards around recycled materials that the global Rotomolding industry could adhere to. He stated that all these issues around sustainability are not going to go away and will become bigger and more important. “It is incumbent on all of us in the industry to work to find solutions,” he said.

Coles ended by saying that despite all the industry’s challenges, Rotomolders are a very resourceful and enterprising breed of people. He is optimistic that the solutions that will be developed will help drive efficiency, increase the range of products made, and ensure the continued growth of the process. R

Selecting the Best Material for Your Application A LV I N S P E N C E , C E N T R O , I N C .

Selecting the right material for an application is one of the most important decisions a molder will make at the start of a project. This important factor can single-handedly govern the success or failure of the product. To make a good decision it is vital that as much information about the fit, form and function of the application is garnered and understood prior to finalizing the design and purchasing tooling. The designer must thoroughly understand functionality and environmental conditions that the product will operate in. For example:

the best solution to any molding challenges by improving appearance and reducing bubble count.

However, if the product requires good mechanical properties such as stiffness, impact strength and tensile strength, then the lowest possible Melt Index

• What are the temperature requirements?

• Will the product have direct sunlight exposure?

• What are the cosmetic and appearance requirements?

• What are the load bearing requirements?

• What are the impact requirements?

• What abrasion resistance is required?

• What chemicals will the product come in contact with?

• What are the dimensional requirements?

• What are the specifications of the mating pieces?

From some basic investigative work, enough understanding can be gleaned to help identify material options for the application, which will in turn dictate the raw material cost, the shot weight and the processing time required to make the product.

Figure 1: Effects of Melt Index and Density on Properties

The Influence of Melt Index on Material Selection

For many applications polyethylene (PE) is the material of choice for the rotational molding process.

One of the most important decisions when selecting a suitable PE grade is what Melt Index (MI) to use. This decision can affect the: • Ability to reproduce the surface detail of the mold • Ability to mold some features such as threads, tight radii or geometry with close wall proximity • Cosmetic appearance of the part, and elimination of surface porosity • Bubble content in the wall of the part • Mechanical strength (impact, tensile, flexural) In general, a higher Melt Index material will provide

combined with an appropriate density will yield the best result. This combination of MI and density is critical in determining the products ability to meet functional and environmental needs. The material selection should never be based on MI alone, as the influence of density is too significant. Figure 1 shows how these characteristics influence the material’s properties[1].

How to Identify the Most Suitable Material with the Lowest Melt Index

When trying to determine the most suitable lowest MI material it is important to understand what the acceptable bubble content is in the finished product.

www.rotoworldmag.com 45

wall may be an indicator of excessive cure cycle time/temperature that could result in oxidation of the inner surface of the part, and poor physical properties.

The Relationship Between Melt Index and Viscosity

Figure 2: Powder Densification and Bubble Diffusion

The reason for this is that in general, the material’s ability to diffuse air bubbles during processing will greatly influence the cosmetic appearance and the mechanical properties. However, as shown in Figure 1, increasing the density can compensate for some property reduction that is caused by bubbles trapped in the wall of the material.

The influence of air bubbles trapped during the powder sintering process cannot be underestimated.

Bubbles form as powder particles melt and fuse together, as shown in Figure 2. If the molding cycle yields a part with a high density of bubbles throughout the wall, then the material properties will not be optimized and may not be adequate for the application. Ideally, the curing cycle should yield a product with a few small bubbles towards the inner layer of the part, so that the mechanical

In order to identify the lowest suitable MI material for an application it is important to realize that the Melt Index measurement is not a true representation of the material’s viscous characteristics when molten. Rotational molding is a “zero shear” process, and one method to assess viscosity at near zero shear is to use a parallel plate, controlled stress rheometer. Research carried out at Queen’s University Belfast[2] using such a rheometer applying very low shear stress provided some insight

into the relationship between temperature and viscosity for natural (unpigmented) materials with a wide range of MIs. The data shown in Figure 3 illustrates the results from these experiments.

The viscosity data in Figure 3 is as expected. As the temperature of the material increases, the viscosity decreases (making it more water-like). Also, high MI materials (i.e. better flowing materials) exhibit lower viscosity measurements, and vice versa for low MI materials. While viscosity measurements are interesting, they only become useful if they are

a diffusion rate for each material at a specific temperature was estimated and listed in Table 1.

The values for bubble diffusion in Table 1 were plotted against viscosity (see Figure 5). From the limited amount of data, it would appear that once the approximate zero shear rate of the polymer is below 3,000 Pa.s, then bubble diffusion will take place. As the viscosity decreases further (with additional heat), the rate of diffusion continues to increase, which helps to diminish the bubble size more quickly, which in turn improves the mechanical properties of the material.

correlated to what happens to bubbles that form during the molding process. Bubble measurement and analysis is possible by using a hot plate test to observe how rotomolding grades melt and form bubbles which diminish in size over time.

When the materials in Figure 3 were observed using a hot plate test, as illustrated in Figure 4, there were some interesting observations: • Materials with MIs above 8 g/10 mins formed a homogenous melt with no bubbles • Materials with MIs of 8 g/10 mins and below formed bubbles which gradually diminished in size • Bubble diffusion was accelerated by increasing the temperature of the polymer melt.

Figure 5: How Viscosity Affects Bubble Diffusion Rate

Figure 7: Zero Shear Viscosity for Black and Natural 5 MI Resin

By closely observing bubbles in the 3.2 and 5 MI materials during a series of hot plate tests and recording and measuring bubble size at specific temperatures, a rate at which bubbles diffuse can be calculated for each condition. Bubble sizes were initially measured, and the polymer held at a set temperature for a period of time before re-measuring the bubbles again. From these measurements

When considering the original viscosity data presented in Figure 3, an imaginary diffusion line (see Figure 6) can be added to highlight the processing temperature that must be reached in order for bubble diffusion to take place with some of the lower MI resins.

This provides the molder with some approximate mold internal air temperature targets that must be reached to allow diffusion to take place. There are several

www.rotoworldmag.com 47

cycle parameters that will influence the amount of diffusion that will ultimately take place, and some experimentation will likely be needed to determine if the majority of the bubbles will have time to diffuse using the molding cycle preferred by the molder.

Generally speaking, understanding how bubble diffusion relates to viscosity, MI, and temperature would suggest that a bubble free part will be produced with a MI of approximately 5 g/10 mins or greater (depending on the cure cycle). However, this conclusion can be influenced by other factors such as pigmentation. For the 5 MI resin used in these experiments, a black pigmented version was also available. When the same zero shear viscosity measurements were performed on the black pigmented grade, the viscosity was noticeably higher across the same temperature range (see Figure 7). Therefore, when comparing the viscosity curve for the 3.2 MI (natural) resin and the 5 MI (black) resin it is assumed that these materials would have similar bubble diffusion rates. This can only be an assumption as there is no way to measure bubble diffusion in a pigmented resin.

If surface porosity and bubbles in the wall are not so critical, then lower MIs can be used. Also, if the part wall thickness is such that longer processing cycles are required then this will allow more time for diffusion of bubbles in lower MI resin, improving physical properties.

Examples of Typical MIs for Rotomolded Applications

Ultimately the molder has to make a material selection for each application, trying to find the right balance of MI and density. Here are a few examples[3] of suggested material MIs for some typical rotomolded products with very specific functional and environmental requirements.

Water and Chemical Storage Tanks

Water and chemical storage tanks come in a range of shapes and sizes and are globally manufactured using the rotational molding process. Tank volumes can be substantial, up to tens of thousands of gallons. These products are typically outdoor products, with a lot of direct sunlight in diverse climates. Product design plays an important role to ensure the geometry has sufficient structure to support the tank content’s load in the environment in which it operates. Quite often ribs are employed

48 ROTOWORLD® ISSUE 5 • 2024

to enhance stiffness in areas of the tank that are subjected to the highest deflective loads.

Material selection

Typically, HDPE materials are used for these applications, with a low MI (1.5 - 4 g/10 mins) and sufficient hoop strength to meet the functional requirements. A high UV rated material is desirable (e.g. UV-15) to help with sunlight exposure. Also, depending on the wall thickness and cycle time a good antioxidant package is required to ensure the material does not thermally degrade during processing. Crosslinked PE (XLPE) may need to be considered, depending on the chemical being contained in the tank.

Toys, Fitness Equipment, and Playground Structures

Toys, fitness equipment, and playground structures are extremely common rotomolded applications.

Products such as dolls take advantage of the process’s ability to reproduce complex 3-D geometries. Other toy products such as the Cozy Coupe, kitchen play sets, wagons, etc., tend to be brightly colored thin wall applications with rounded corners that are relatively easy to manufacture.

However, to be competitive with other processes the cycle time for these products has to be very aggressive. Playground structures are also a very common global rotational molding application because of the durability and weatherability of the PE material used.

Material selection: For soft touch and flexible products, Poly Vinyl Chloride is used. This material can replicate the most intricate of details, as seen in PVC dolls heads/bodies. Other toy products are manufactured from LLDPE such as the Cozy Coupe, kitchen play sets, wagons, etc., with a medium to high MI (5 - 7 g/10 mins) to aid good flow, ease of processing and removal of bubbles quickly, which is desirable for cosmetic reasons.

Fuel Tanks

Fuel tanks for tractors, construction equipment, trucks, marine engines, generators, compressors, lawn and garden equipment, etc. represents a significant rotomolding sector. Many of these products can be extremely complex in design and include an array of assembled components. For example, agricultural fuels tanks are typically one of

the last components to be designed for the vehicle, which results in a very complex geometry to take advantage of any available space to maximize the tank’s holding capacity.

Material selection: The material of choice for these applications is XLPE because of its UV stability, low temperature impact strength, environment stress crack resistance and its ability to pass various test requirements such as ECE 34. Crosslinked PE has also been used in combination with other materials that provide excellent resistance to hydrocarbon emissions, to reduce fuel weigh loss from gasoline tank applications. Prior to crosslinking, the crosslinkable grades available to the industry will flow very well as they are typically manufactured from a high MI resin (upwards of 20 g/10 mins), giving these materials the ability to reproduce difficult to fill geometries such as thread profiles.

Floatation & Insulated Products

Polyethylene’s buoyance, water resistance, weatherability and toughness, all help to make it an excellent choice for rotationally molded flotation products. Fishing buoys, boat ramps, and floating docks are all common rotomolded products. Some floating docks incorporate PE foam to fill the cavity and/or increase buoyance. Kayaks and canoes are also commonly rotationally molded and often include PE foam and are molded using a rock and roll machine because of their geometry. In recent years there has been a notable move towards rotational molding for insulated coolers. Several of these products include PU foam between the external and internal PE layer. This provides excellent insulation properties, allowing the contents of the cooler to remain chilled for several days.

Material selection: The material of choice for these applications is polyethylene with lower density materials providing better bouyancy. The addition of foam will further enhance bouyancy. These products will benefit from a material with a good UV package and good impact properties. Typically, LLDPE materials would be used for these applications with a MI in the range of 3 - 7 g/10 mins.

Material Handling, Waste Disposal Products, and Floor Cleaning Containers, pallets, IBCs, totes, trash cans, dumpsters, etc. can all be common rotationally molded products. Cases and containers can be

highly sophisticated for the purpose of carrying and protecting valuable goods. IBCs are commonly used for transportation of chemical products. Trash cans and dumpsters are also common applications for the process and can often incorporate recycled material. Single piece septic tanks can be manufactured using the rotational molding process.

Floor cleaning equipment benefits from the process’s ability to mold highly complex geometries that are capable of holding cleaning fluids at elevated temperatures.

Material selection: The material of choice for these applications is polyethylene. However, IBCs may require a stiffer HDPE material because of the load carrying requirements for this product. Also, XLPE may be required depending on the chemical being contained in the tank. Waste disposal and floor cleaning products can be manufactured from LLDPE material, with a density in the 935–939 kg/m3 range and a MI in the range of 2 - 5 g/10 mins.

Custom Applications

In addition to those previously mentioned, there are many other industries and applications that utilize the rotational molding process. These include: air ducts, cargo beds, blower housing, hydraulic tanks, urea tanks, roofs, fenders, consoles, display cabinets, road barriers, traffic signs, laundry carts, furniture, plant-pots, mannequins, hoppers, rickshaws, etc.

Material selection: The material of choice for the majority of these applications is polyethylene.

Typically, with a LLDPE material, with a density in the 935–939 kg/m3 range and a MI in the range of 3 - 7 g/10 mins. However, hydraulic tanks will be subjected to higher temperatures when in use and depending on the maximum temperature requirements will need to use either a XLPE, XL11 (XLPE/Nylon 11 combination), Nylon 11 or Nylon 6.

Nylon 6 will have the highest temperature range for these applications.

ALDO QUARATINO Matrix Polymers

Revolutionizing Rotomoulding: The Intersection of Sustainability, Innovation, and Cycle Time As the global interest in rotomoulding continues to grow, this versatile polymer processing method remains constrained by persistent challenges. Despite its widespread application, the process still suffers from long cycle times, a limited range of materials, and inefficient heat transfer mechanisms. These issues—pinholes, voids, clogged breathing systems, and basic

design errors—are the same hurdles faced by moulders decades ago. While advances in technology have reshaped many other manufacturing processes, rotomoulding has yet to experience a revolutionary shift that fully addresses these limitations.

Cycle time remains a critical concern. Compared to other plastic processing methods, rotomoulding’s lengthy cycles hinder productivity

and efficiency. This inefficiency, largely stemming from poor heat exchange between the burner, air, mould, and polymer powder, exacerbates energy consumption and environmental impact. A primary opportunity for innovation lies in reducing cycle times without sacrificing product quality—an outcome that would not only boost productivity but also decrease the industry’s carbon footprint.

Formation of Pinholes

One of the major challenges during the rotomoulding process is the formation of pinholes. As the mould rotates in the oven, the heat causes the outer surface of the polymer powder to become tacky, allowing the particles to coalesce against the mould wall during the sintering phase. During this phase, pockets of air can become trapped between the powder particles, eventually forming bubbles or pinholes. While these air pockets will gradually diminish over time under heat, eliminating them can require extended oven time. However, keeping the polymer in the oven for too long risks degrading the material’s

mechanical and physical properties, such as impact strength and flexibility, resulting in brittle final products.

Managing the balance between adequate heating and avoiding overexposure is crucial. Too short a heating cycle leaves the polymer under-sintered, with insufficient coalescence of the powder, while excessive heating leads to degradation. In commercial production, moulders often check for pinholes by shaving through the part’s thickness.

Too many pinholes indicate undercooking, while no pinholes might suggest overcooking, which causes brittleness. The goal is a mould with minimal pinholes near the part’s interior, ensuring optimal performance without compromising the material’s durability.

Rethinking Cycle Time and Thermal Efficiency

The extended sintering phase is a direct consequence of the absence of pressure in the rotomoulding process. Reducing the sintering time would significantly shorten the overall cycle time, leading to greater efficiency. Extensive research on this topic has led to the development of faster cycling materials. Matrix Polymers introduced such technology years ago, and many moulders have since benefited from these innovations. However, there is still untapped potential for further advancements.

Education and awareness of these technological breakthroughs are vital for the industry’s future.

Training new moulders on the latest material and process innovations should be a priority,

as informed moulders are better equipped to make sound decisions on material selection and process optimization. The introduction of advanced material solutions is only part of the solution.

Enhancing heat transfer and improving thermal distribution are equally essential steps toward reducing CO2 emissions and streamlining shop floor operations.

The Path Forward: A Sustainable Future for Rotomoulding

As the world moves toward a more sustainable future, the rotomoulding industry must play its part. Reducing cycle time and improving energy efficiency are critical steps toward minimizing the environmental impact of production. Every incremental improvement in heat transfer, material selection and process control contributes to a greener, more sustainable rotomoulding industry.

Incorporating these advances into standard practice requires leadership and a commitment to change. Business leaders in the field must prioritize sustainable innovations and seek out ways to reduce their resource consumption. Educating the next generation of moulders on these principles is key to ensuring that the industry thrives while minimizing its carbon footprint.

By embracing innovation and sustainability, the rotomoulding industry can evolve, becoming more efficient and eco-friendly while meeting the demands of an ever-changing market. Each step we take today brings us closer to a more sustainable tomorrow. R

ROTO AROUND THE WORLD

INTERNATIONAL PARTNERSHIPS In today’s increasingly globalized business environment, companies that expand their reach beyond borders often find themselves at a competitive advantage.

Collaborating with international partners can open doors to a range of opportunities that are otherwise inaccessible within a single domestic market.

While you may be able to successfully export your product without the need to develop a business relationship with a foreign company, in this article I will discuss some of the advantages of having your

proprietary product manufactured and sold in an overseas country.

Why get your product moulded overseas Some of the key benefits of collaborating with an international rotomoulding partner can be identified as: (1) Gaining quicker and easier access to new markets.

International partnerships allow businesses to expand their reach into new countries, tapping into diverse customer bases and boosting revenue potential.

(2) Tapping into diverse expertise and innovation. Different markets

and cultures often bring with it different perspectives.

International partnerships encourages innovation and offers different ideas for problem solving and product development. (3) Cost efficiency. Many rotomoulded products are large or bulky, which means shipping overseas can be an expensive additional freight cost either reducing your profit margin or increasing your costs making it uncompetitive. Moulding the product overseas avoids these extra international transport costs, longer delivery lead times, and potential tariffs or import

taxes. (4) Enhanced competitiveness. Collaborating with international partners can help your business stay current with global trends and best practices, improving your competitive edge.

Globalised economy

Vadodara, in the northwestern coastal Indian state of Gujarat. However, Baroda also rotomould a range of their own products.

Their 14,000sqm (150,000sqft) factory produces a wide range of products which are sold domestically and exported around the world. These include kayaks, boats, pipe floats, furniture, planters, silos, agricultural tanks, water tanks, and industrial tanks.

Baroda has been in business for over 30 years and operate Reinhardt Teknik rotomoulding equipment, with swing sizes ranging from 2.5m (98”) to 6.4m (251”).

There may be limitations when dealing with international partners, for example, poor proximity to specific raw materials or inadequate manufacturing capabilities. Or conversely, you may find working with overseas rotomoulding partners provides a wider range of suppliers to choose from, and potentially higher quality or lower cost components than your own country, which may enable your product to be sold at an attractive price point overseas which helps to grow everyone’s overall business revenue.

Many countries around the world promote the concept of manufacturing products domestically instead of importing them. In 1986, Australia launched an “Australian Made” initiative. The “Make in India” initiative was launched by Indian government in 2014. In 2015 the “Made in Britian” initiative was launched to promote British manufacturing. The list goes on as each independent government seeks to boost YOLO Kayaks its manufacturing sector to increase selfreliance – to varying degrees of success.

Baroda Polyform Private Limited (Baroda) has some Since the end of 2021, the entire Baroda Polyform different international partnerships in action. Baroda power consumption has become green consumption, is primarily a custom rotomoulder operating from reducing their carbon footprint.

They have a 575KW solar plant installed on their factory roof. This coincided with commissioning their first Reinhardt RSX-e series 27 Green machine with a swing of 2.5m (98”) running 100% on solar power.

In 2015 Superior Jetties LLP – India, was born in a joint venture between Baroda and Superior Jetties, another Australian business.

Superior Jetties is a Queensland business based on the Gold Coast who have over 30 years experience providing comprehensive design and construction services, specialising in engineering, manufacture, and installation of marine structures.

The goal of Superior Jetties LLP is to revolutionise water transport infrastructure in India combining the extensive practical marina experience of Superior Jetties Australia and the rotational moulding expertise of Baroda to supply docking solutions within India and its neighbouring countries. These include marinas, private pontoons, pump floats, pipe floats, boatlifts, boardwalks, and marine piling.

All products sold under the banner of Superior Jetties LLP are being manufactured exclusively by Baroda for Superior Jetties LLP using the Australian technical knowledge.

Importantly this arrangement has enabled Superior Jetties LLP to implement the “Make in India” initiative by the Indian government.

World of opportunity

Boat parking dock

The kayak business in India became so successful that Baroda eventually acquired all the capital equipment and technology from the Australian company and in 2018 re-launched the kayaks under its own YOLO brand.

After 20 yrs of experience Baroda had their own design team specialising in marine craft and were developing their own new kayaks for the domestic and international market.

In 2021 they began manufacturing and marketing their own boat designs, up to 4m (13ft) in length.
