LETTER FROM THE CHAIR

The Possibilities of Rotational Moulding Welcome to the third annual edition of the ARMO (Affiliation of rotational moulding Organisations) rotational moulding Product Showcase.

As you know the purpose of this publication is to educate the world about the possibilities of rotational moulding, but also to show people that it is possible to create attractive, innovative, practical, and economical products through this very versatile technology.

With the invaluable support of our sponsors, this publication will be used throughout the world, both within and outside the industry, to raise the profile of rotational moulding.

It is a great pleasure to see the success of this publication year after year. This is the third edition, and it is still overflowing with very interesting products.

“Education is one of ARMO’s prime objectives.”

This is a clear sign that our enterprises are continuing to invest in innovation and to develop original solutions to manufacture increasingly more complicated, more attractive, and more efficient products.

Rotational moulding is continually innovating and improving. New machinery advances with the increased use of automation is changing the image of the industry: new materials can now be moulded with rotational technology.

then we are winners. Finding the right balance among productivity, job satisfaction, and professional growth is where to go. The added value this brings to our companies allows us to grow, innovate, and stay abreast of the market. Investing in your workforce includes education. Of course, education is one of ARMO’s prime objectives.

ARMO and we affiliates must continue to educate and inform not only the international design community of the possibilities that are becoming available using the rotational moulding process, but also the people in our companies. Deepening knowledge and appreciation of the technology will help ensure its continued expansion and innovation.

ARMO currently has 12 affiliates around the world working together to advance and promote the rotational moulding process worldwide. We aim to continue doing this with passion and determination.

Sincerely,

Katia Zoppetti ARMO Chair katia.zoppetti@dramsrl.com

However, we must not forget that today, true innovation is about people being able to reinvent themselves based on their customers’ requirements. We should never undervalue the importance of knowing how to listen: we all say this but how many of us do this? In our 4.0 world our companies must keep up with our rapidly evolving markets and the way to do this is to listen to our customers, to invest in our people, and to reduce waste.

What a real challenge investing within our people is! If we can only get each person in our companies to be satisfied with their job 2019-2020 ARMO Rotational Moulding Product Showcase

Locker Wave by Prolocker ™

The most innovative storage locker of our time.

Designed and manufactured by Spincraft Mexico S de RL de CV - Mexico

Locker Wave™ is a new generation storage locker that is not only functional, but also stands out. It has been designed to inspire new sensations in its space and provide a wow-effect to its users. With lines inspired by the Mexican ocean, Locker WaveTM grants freshness and character in schools, restaurants, gyms, industry, or any place that requires an intelligent safekeeping locker solution.

With lines inspired by the Mexican ocean, Locker WaveTM grants freshness and character in schools, restaurants, gyms, industry, or any place that requires an intelligent safekeeping locker solution.

The fifth generation locker is durable, heavy-duty, low in maintenance, washable, eco-friendly, and features a digital lock – all rendering Locker Wave™ the most innovative locker of our time. Compared with traditional and cheaper steel sheet models, it is aesthetically pleasing and fulfills international standard requirements for any type of industry.

Locker Wave™ production began in 2018, utilizing the rotational molding process. This allowed many advantages to be incorporated into the design and functionality of the product including: reinforcing ribs that truly oppose the forces created when someone tries to open its doors forcefully; an initial low production volume, meeting the initial demand for the product; and the ability to change the product color from one cycle to the next (if going to a darker color). Additionally, the investment in molds was lower than with other processes, making rotational molding

the ideal process, as opposed to the traditional steel sheet option.

Prolocker has taken on a new way of thinking and manufacturing its plastic lockers by utilizing I’m Green™ Polyethylene. In doing so, they are doing their part in taking care of the global environment. I’m Green, produced from sugarcane, is a renewable raw material, while traditional polyethylene uses fossil sourced raw materials such as oil or natural gas. This improved polyethylene captures and fixes CO2 from the atmosphere during production, which helps to reduce greenhouse gas emissions. It retains the same properties, performance, and application versatility as polyethylene from fossil origin, and is recyclable within the same chain of recycling traditional polyethylene.

Galaxy Villa has a space capsule design, solar power generation on the top, and technology and environmental protection.

Nowadays, modern society is highly developed. A new connotation has been endowed to people’s pursuit to quality of life.

On one hand, the convenience in life brought by modern technology cannot be abandoned; on the other hand, people tend to pursue a life that recovers its original simplicity, hoping to experience peace brought by harmony between humans and nature. Therefore, a villa, log cabin, tent, and some other accommodation forms have become the first choices for being closer to nature. Nevertheless, the traditional log cabin and tent have their shortages in antiseismic property, fireproofing performance, and comfort, so delight in the journey may be discounted. For the purposes of comfort, safety, environmental protection, and being close to nature, Zhejiang BST Technology Co., Ltd. has cooperated with China Jiliang University to design Galaxy Villa that meets people’s dual demands in life.

Galaxy Villa is made by a new-type of rotomoulding, with an original patent for invention and intellectual property. The height of Galaxy Villa is 3.5m and its diameter is 7m.

The internal area reaches 36m2. Its panoramic sunroof and French window are designed for the product. Its bedroom, intelligent kitchen, independent toilet, bathroom, and leisure room, etc. are designed for indoors to meet people’s life demands as far as possible.

Galaxy Villa is made in modularization and standardization, so it can be assessed and moved rapidly.

In performance design, Galaxy Villa has a large transparent glass wall and panoramic sunroof to provide a wide view. A guest can lie on the bed to look up at the sky and look around

nature. Integrating with nature sufficiently, a guest can seek their true self in harmonious exchange. Galaxy Villa is designed in a space capsule shape. The solar cell panel is designed on its roof for power generation. An integrated system is set at the bottom for sewage treatment, which is both technological and environmental. Overall, an intelligent control system is used in Galaxy Villa to control the curtain, lock, and home appliances intelligently by using voice and a mobile phone. In the evening, LED lighting can be controlled to emit different lights. By programming, Galaxy Villa can move following the sun and moon. In this way, one can choose the scenery and position desired and appreciated.

All materials used in Galaxy Villa are green and environmental. The shell is food-grade rotomoulding material PE; the upholstery is green and an environmental material of blowing plastic uptake in a space capsule design philosophy. The wainscoting is made of the latest environmental bamboo fibers.

With a high-strength structure, Galaxy Villa can be used for multiple purposes. For example, it can be used as an accommodation, revolving restaurant, administrative service center, and business center.

All rotomoulding pieces can be manufactured by the equipment of diameter 2.5m. The design, development, and manufacture of molds are jointly completed by BST Technology and Wenling Rising Sun Rotomolding Technology Co., Ltd. bst-tech.cn wlxuri.com

Cabana Suite Spas A Spa with stunning looks, comfort, and convenience – everything you’ve dreamed of in a spa hot tub experience.

Designed and manufactured by Dream Maker Spas - USA

The Syncrylic™ formulation was created to obtain the best of both worlds — the beautiful appearance of acrylic along with the tough, impactresistant qualities of polyethylene.

Step into the Suite Life with Cabana Suite Spas by Dream Maker Spas. The first in its class, Cabana Suite Spa series brings you stunning looks, comfort, and convenience — everything you’ve dreamed of in a spa hot tub experience.

• Black Diamond with Black trim and cabinets • Black Diamond with Gray Trim and Cabinets • Sahara Diamond with Coffee trim and cabinets

Available in both 2500L/S and 3500L/S models, Cabana Suite Spas include an umbrella, a cover lifter, large suite steps with sturdy handrail, storage, and planters, along with a built-in fountain and LED lighting, all included in one single design.

Inside the hot tub you’ll enjoy perfectly formed lounge or guest seats, soft contoured head rests, an entertainment table, and builtin cooler compartment.

In any combination, a Spa Suite is rotomolded with sparkling, sophisticated Black Diamond, White Diamond, or Sahara Diamond, which will blend beautifully into any outdoor or patio environment.

With help from our outstanding polyethylene resin supplier, Jerico Plastic Industries, all Cabana Suite Spas are manufactured using an innovative, high quality Syncrylic™ material.

The Syncrylic™ formulation was created to obtain the best of both worlds — the beautiful appearance of acrylic along with the tough, impact-resistant qualities of polyethylene.

The Cabana Suite Spas comes in 3 base colors with different color trim and cabinets for a total of 6 color combinations, which include: • White Diamond with Espresso trim and cabinets • White Diamond with Gray trim and cabinets • White Diamond with Taupe trim and cabinets

Previously, the most common method for producing a hot tub has been through the use of acrylics, fiberglass, and resins, requiring an internal framework of steel or wood to support the structure to keep its shape and prevent damage. By using rotational molding to manufacture their hot tubs, Dream Maker Spas is able to achieve a strong unibody design with finishes that achieve the same aesthetic appearance as acrylic, but are lighter in weight with greater durability and strength, and come at a lower cost.

For extra convenience, the Cabana 2500S offers Plug and Play compatibility and arrives ready to fill with water. For those who prefer extra therapeutic performance you can upgrade to the Premium 3500 models. These spas have an extra pump, 35 jets in total, and combine the uniqueness of the “Suite” concept to bring an exceptional consumer value. Available in both 50Hz and 60Hz. dreammakerspas.com

C Custom Coolers 3

Innovative electric remote-controlled coolers.

Designed and manufactured by Seljan Company - USA

The need for motors, speakers, headlights, and other features made the shape of this product very complex, thus a perfect fit for the rotational molding process.

C3 Coolers are equipped with a three-speed remote control, Bluetooth speakers, LED headlights, USB phone charging port, and also hold 30 cans with a twenty-pound bag of ice. They come in three product designs: The Rover; The Delivery Truck; and the Zamboni. The innovative C3 Coolers are licensed with the NFL, NHL, ZAMBONI, MLB, NCAA, and Warner Bros. Seljan Company also brands these coolers for corporations throughout the world.

Although it is a remote-controlled product, handles have been designed on both sides of the cooler, as well as front and back, to provide a comfortable means for carrying the product as needed. Accessories include cup-holders, as well as accessory shelves, which are part of the design to make room for a cell phone, the remote, etc. Other add-on features make the product even better, such as window flag brackets, roof racks, fender flares, running boards, and trailers.

All C3 Coolers are fully foamed and available in custom colors and vinyl graphics made in Seljan’s art department. Originally developed as a promotional product for a beverage company, the C3 Cooler has steadily grown into a perfect fit for the branded corporate world as well as the license community to become a highly sought-after show piece. Yearly these coolers can be seen at the NFL experience in the Super Bowl and the Calabasas Film Festival, among other events throughout the world, turning heads and making people smile. The coolers also have a large following from families and youth sport teams that are looking for a quality cooler with the convenience of the remote-control feature to help get them from point A to Point B.

The parting line was carefully located to allow for graphics to be molded-in if requested.

The drain plug is cleverly located to mimic an undercarriage oil-drain plug on a vehicle. The cooler area is a perfect storage for the few components that need to be assembled once the customer receives the product. The size of the partially assembled unit was specifically designed to allow its shipping box to meet required UPS and FedEx limits.

The C3 Cooler was designed in-house by seasoned Seljan Company product designer Aaron Smith with assistance from the company’s rotational molding and marketing professionals Dru Laws and Mark Pelchat.

One of the many unique characteristics of this exciting product is the internal electronics.

The front motor is external to the part, as is a portion of the rear drive system. The rest of the electronics are housed within the product.

This presented some challenges when post-process polyurethane foaming, which is needed for traditional cooler insulation, and it also protects the electronics. The surfaces of the cooler are intentionally smooth to provide maximum “billboard” space for private branding of the product.

Rotational molding was specified for the product’s manufacture. The need for motors, speakers, headlights, and other features made the shape of this product very complex, thus a perfect fit for the rotational molding process.

Seljan Company utilizes multiple molds to satisfy larger orders requiring a quick turnaround. Seljan not only provides the rotational molding of the product, but also most of the injection molding and steel fabrication for all the components in the assembly.

Ultimately, the product line is a perfect combination of Seljan Company’s abilities from concept to mold building and manufacturing.

Antique Ceremonial Coffin A ceremonial coffin used in state funerals for high-ranking officials or senior statesmen and ladies.

Designed by the Royal Thai Office and manufactured by SCG Rotomolding Center - Thailand

This rotomolded product is a replica of antique artifacts unique to the Kingdom of Thailand, dating back more than 200 years and still in use today for state funerals for high-ranking officials or senior statesmen and ladies. Its purpose is to store a deceased body during a religious rite, which can last from days to weeks before the body is transported in this container to the crematorium. Traditionally, the original coffin has been made of carved wood, painted with tree enamels, and coated with gold leaf. Over time, the wooden coffins become degraded and have to be replaced.

It was decided rotomolding would be the best option for producing this part, both technically and economically.

Today, such wood is rare to find, there are fewer skillful craftsmen that can recreate these types of artifacts. Therefore, the Palace Office initiated a conservation project to re-create this product with a material that is durable, light to transport, and robust for handling, yet maintains the original look and feel of the ceremonial coffin.

It was decided rotomolding would be the best option for producing this part, both technically and economically. The rotomolded antique coffin consists of five main components: (1) the base – two halves; (2) the body – two halves; (3) the wedding cake-shaped top; (4) the bell-shaped top; and (5) the Chrysler. The coffin includes about 300 smaller ornamental pieces that are compression molded. Its design faithfully follows that of the original artifacts with few modifications on the intricate details so that molding is possible. The pattern was created by craftsmen of the Thai Royal Palace Office, the mold was manufactured by Maus Gmbh – Germany, and the parts were molded at

SCG’s Rotomolding Center. The final parts were finished and decorated with colored mirrors and gold paint in the Thai Royal Palace Office’s workshop.

There are 120 parts required for this project.

The investment in molds is reasonable, compared to injection molding and/or blow molding. Initially, there was an attempt to fabricate this part by fiberglass hand-layup, however, the fiberglass prototype was found to be too heavy, easy to break, and poor in surface finish.

SCG’s color compound medium-density polyethylene (MDPE) with 932 density and Melt Flow Index (MFI) of 7 was chosen for this job due to its consistent dimension stability and its ability to fill-in intricate details.

Color compound MDPE is light compared to fiberglass and also durable compared to wood. It is resistant to sunlight, termites, and moisture. It can be molded to create intricate details that mimic a wood carving.

This one of a kind product may be the first antique-looking product in Southeast Asia that has been made by rotomolding. It is a demonstration of how art and engineering can be combined to create something antique-looking, but features modern day performance. It is also a showcase that rotomolding can create opportunities not only in industrial or domestic applications, but also relating to art and historical conservation. scgchemicals.com

Rotational Molding Continues to Surge

by Alvin Spence, Centro Incorporated

42 2019-2020 ARMO Rotational Moulding Product Showcase

The industry is healthy, growing, and continues to become a more technology focused process in the established regions.

While rotational molding remains a small niche in the plastics industry, it continues to provide much needed cost-effective products to both consumers and Original Equipment Manufacturers (OEMs) throughout the world.

Indeed, several OEMs have helped grow the global footprint of the rotational molding industry as they have expanded into new regions and required rotomolded products for their assembly lines. These new regions include countries such as India and China, where labor is abundant, but where the supply base for molders is not as strong as in more established regions such as Europe and the US. Nevertheless, these developing regions will help the rotational molding industry to grow a stronger global footprint and will increase the amount of polymer consumed by the process. It is interesting to note that some of the more established sectors of the world, such as Europe and the US, are challenged by escalating labor costs and/ or a labor shortage, which is impacting the competitiveness of the process. However, the reduction in polyethylene raw material costs due to an increasing global supply chain capacity is helping to offset some of the labor cost increases. Regional economic climates are also impacting the industry. For example, the current growth of the US economy has resulted in rotomolders enjoying healthy order books, even though they are struggling to find enough labor to manufacture the products. This is because the process is very labor intensive and those entering the workforce are not attracted to these types of manufacturing positions.

Therefore, the industry is relying heavily on seasoned labor which is becoming increasingly difficult to find, and more expensive.

So, what does this mean with regards to the state of our industry? Generally speaking, the industry is healthy, growing, and continues to become a more technology focused process in the established regions. It is absolutely critical that industry leaders continue to strive for efficiency improvements, as a recent article

by Dr. Peter Mooney[1] would suggest that the manufactured product value per labor hour ($/hr.) is in decline in the US. While this trend is alarming and needs to be addressed, it may well result in greater use of automation technologies that are readily available to the industry, or it may spur the development of

new methods to improve labor efficiency, which can only be good for the long-term health of the industry. Regardless of the challenges we face, the fundamentals of why rotational molding is a process of choice remain favorable in many diverse applications.

What sets us apart?

It is always a great experience to attend a gathering of industry members and this is particularly true with the rotational molding industry. It is a time of sharing knowledge, networking, and seeing what others can do with the process. Quite often there are products of high complexity on display that can challenge many of us to simply wonder “how did they do that?”. It is amazing and inspiring to see these offerings either at industry events or in industry publications such as RotoWorld®. This is the essence of rotational molding and one of the factors that really sets the industry apart. Without doubt, one of rotational molding’s greatest attributes is design freedom and the complexity of a product that can be manufactured with this process.

Compared to fabrication methods or alternate plastics processes, rotational molding offers tremendous design freedom to create the most complex of 3D geometries. The only limitations are simply the size of equipment available and the mold builder’s ability to manufacture a mold that can facilitate the loading of the raw materials and unloading of the part. When complexity of product is combined with larger part size, there are very few cost- effective alternatives to rotational molding, provided the molder is located within a reasonable shipping distance from the end user.

Mold building has been a key part of the industry and will continue to be an area of development that will help the industry to improve efficiency and grow into new market sectors. Highly complex 3D parts will ultimately be produced using molds of very high complexity, and in some cases will require dedicated processing equipment if alternate heating methods such as electricity is required.

Complex geometry can result in molds having 4, 5, or 6 pieces (or more) that slide together, combined with several loose pieces. These types of molds require highly skilled operators to carefully manage the loading and unloading steps. They also require a regular maintenance

schedule to ensure the mold functions as intended. For applications requiring precise wall thickness control, electrically heated molds are a viable option, providing the ability to have specific heating zones on the mold. For example, if a part has a deep core or a large molded-in metal ring or insert, more heat can be applied to these areas of the mold resulting in better material coverage. Conventional cast or CNC cut molds can compete with electrically heated molds, but it will require a lot more effort by the molder to get the required material distribution if the geometry is more challenging. However, much can be accomplished by using thermal pins, shielding, air movers, varying mold thickness, etc. to achieve the desired outcome.

I believe there is another factor that helps to set rotational molders apart from others, and that is an ability to improvise and find creative solutions to solve problems. Many rotomolders possess this entrepreneurial spirit. This is apparent in designs that utilize novel geometry to overcome the mechanical limitations of the raw material or designs that combine materials to meet the functional needs of the application.

What products identify rotational molding?

There are several product categories that combine to represent a lot of what identifies rotational molding. These products really tell the story of where and why rotational molding competes favorably with all other manufacturing processes. Here are several product families that are typically rotationally molded: Water and chemical storage tanks Water and chemical storage tanks come in a wide 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. Product design plays an important role to ensure the geometry has sufficient structure to support the tank contents load in the environment in which it operates. Quite often ribs are employed to enhance stiffness of the wall and/or wall thickness is targeted to areas of the tank that are subjected to the highest deflective loads.

Typically, HDPE materials are used for larger tanks with sufficient hoop strength to meet the functional requirements. Often carousel

machines or rock and roll machines are used to manufacture these products. The applications for this type of product family include water storage or harvesting, static fuel storage, and chemical storage.

Toys, fitness equipment, and playground structures Toys, fitness equipment, and playground structures are extremely common rotomolded applications. For soft touch and flexible products, poly vinyl chloride is used. This material can replicate the most intricate of details, as seen in PVC doll heads.

Other toy products are manufactured from LLDPE such as the Cozy Car, kitchen play sets, wagons, etc. These products 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, and therefore molders of these products are either highly automated and/or embrace a culture of lean manufacturing. Playground structures are also a very common global rotational molding application because of the durability and weatherability of the PE material used.

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

For example, agricultural fuel 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. These types of applications can include several inserts, bosses, drain plug, graphics, sending units, etc., all of which must be leakproof. The material of choice for these applications is Crosslinked Polyethylene 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

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

excellent resistant to hydrocarbon emissions, to reduce fuel weight loss from gasoline tank applications. Many small off-road engines and marine fuel tanks benefit from this material combination to meet environmental regulations.

Floatation & insulated products Flotation of plastic has now become a household topic and a serious problem for the plastics industry. However, 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 handling, waste disposal products & 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.

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 (typically from Nylon 6 or 11), urea tanks, roofs, fenders, consoles, display cabinets, road barriers, traffic signs, laundry carts, furniture, plant pots, mannequins, hoppers, rickshaws, to name a few.

Development of the industry During the past 20-30 years the industry has experienced several technological developments that have helped to advance the state-of-the-art from being somewhat of a “black art” to having much more process control. One of the most significant developments to accomplish this was the discovery of the importance of the mold’s internal air temperature measurement as being the key to providing real-time process control. This development allows molders to quickly determine optimal processing parameters, avoiding unnecessary scrap by trial and error. The benefits of measuring the mold’s internal air temperature are now well known and understood, but it is disappointing that this is not a standard operating procedure for the majority of molders, and remains more of a diagnostics tool when needed. If the industry is to continue to advance, then control of the mold’s internal temperature (and pressure) must be something that equipment and mold manufacturers make more readily available to molders.

Another area of great opportunity and much talked about over the years is the limited palette of materials that are suitable for the long sintering cycle required for this process.

Rotational molding could benefit greatly from a moldable material with a scratch resistant surface. This type of material would open up a host of opportunities for molders all over the world. Even though rotational molding represents a small niche, it is surprising that more effort by material suppliers is not focused on fulfilling this need, either with a single layer material or a multi-layer system backed with polyethylene. There is no doubt that a cost-effective solution could yield a significant growth opportunity for the industry.

While rotational molding needs to continue to utilize more process control and expand its material offerings, it also needs to become more efficient and less labor intensive. As labor costs rise, and as labor becomes less available is some regions, it is imperative that molders find suitable technologies to either reduce the amount of labor required or reduce the skills needed to yield the finished product.

For example, the application of a release agent to a particular mold requires an operator to

have some skill and knowledge regarding how much release to apply, where to apply it and how frequently. This decision making can be eliminated if a permanent release mechanism is applied to the surface of the mold, yielding a more consistent product. Another efficiency opportunity is to minimize machine downtime due to mold changes. This is something that all molders are faced with and can result in loss of productivity of the machine and the labor assigned to finishing parts off the machine.

If molds can be changed and arms balanced inside the load/unload cycle time, then great gains can be made in overall equipment efficiency and the revenue produced per labor hour. While rotational molding will always be a labor-intensive process, the industry must find ways to minimize the effect of escalating labor costs and labor shortages by employing automation where it makes viable economic sense. In some regions of the world the future of the industry’s competitiveness will depend on its ability to apply technologies that improve labor efficiency.

Future of the industry As the rotational molding industry continues to develop, there is no doubt that its future remains extremely bright. That is because the process is highly capable of cost-effectively manufacturing the most complex of products, with a wide variety of size and wall thickness.

Designers are excited about the process’s ability to replace metal components with plastic in functional applications for light-weighting of parts or to add styling and contours. Rotational molding really fits well with these types of opportunities as well as being able to combine several parts into one, yielding a much lower product cost. With mold costs being very attractive compared to other plastic processes, there is a lot to get excited about when considering the rotational molding process.

As the variety of applications for the process continues to expand, and as the process continues to develop, it will be exciting to see the increase in global growth for the industry over the next decade and beyond.

Blending Lifelong

Passions with Outstanding Design and Business Leadership

All these products share one thing in common, they are rotationally molded.

Jackson fishing kayak

Most of us work to pay bills and provide for our families. Within this population is a small portion of us who enjoy our work and gain satisfaction from our jobs. Then there is a very small elite group of workers who have managed to derive a living from their passions blurring the boundaries between work and lifestyle. Jackson Kayak is a company started by Eric Jackson who has managed to realize his dreams by co-founding a kayak company which has successfully flourished as one of the world’s preeminent kayak manufacturers.

Mr. Jackson is a four-time Whitewater freestyle world champion whose talents and skills have been passed on to his children who have also been recognized as world champions in kayaking and whitewater sports.

The entire Jackson family is dedicated to whitewater kayaking and outdoor sports as part of their lifestyle as well as their business.

This deep-rooted connection between passion and business has enabled Jackson Kayak to evolve as the world’s leading kayak manufacturer. Their products are designed and developed based on a personal love of the sport as well as a keen perception of all the subs-tiles associated at every level of detail. Therefore, this is an article about this company, it’s designers, it’s design philosophy, and its outstanding products.

I have personally designed hundreds of products in an equal number of diverse markets throughout my career. Many of these products have been extremely complex systems based on state-of-theart technologies involving hundreds of components and intricate parts. This does not mean I could proficiently design a kayak.

A matter of fact, designing a kayak is very complicated due to the highly integrated

relationship between the user and the product at every level of detail. The design of recreational products such as kayaks, surfboards, skis, or skateboards all require a special intimate knowledge, which can only be gained with extensive experience during use. Simply executing a design based on aesthetics or technical engineering skills is not enough to proficiently design any of these products. This is also true of a musical instrument such as a violin or piano.

A master violinist or pianist has developed his or her skills to a level at which their fingers can feel subtle differences in surface

texture, the touch of a key on the keyboard, or the subtle shape of a violin neck. These perceptions are imperceptible to a nonmusical designer who would find it difficult to address these design details in a satisfactory manner. That is why Jackson’s product line attracted my attention.

The remainder of this article will discuss the unique staff and design methodology, which has set Jackson Kayak apart from its competitors. Many of the people employed at Jackson Kayak are avid outdoorsmen with a passion for hunting, fishing, kayaking, and whitewater sports. In fact, my interview of Damon Bungard, product and brand manager, who generously provided me with all the information for this article, is also a professional hunter, fisherman, and kayaker.

His passion and experience provide him with

invaluable insight to help refine Jackson products with unique features setting them far apart from their competitors.

The company has expanded its product line from recreational and whitewater kayaks to fishing kayaks, catamarans, as well as high end hunting coolers. All these products share one thing in common, they are rotationally molded. Another common and more important similarity is a very distinctive identity that immediately is associated with the Jackson brand. Although product branding is overused to a point of being clichÊ, it is truly integral to Jackson’s product line and marketing strategy. Jackson has cleverly captured a lifestyle of excitement, appreciation of nature, sport fishing, and good health within their advertisements, graphics, as well as all their products.

My introduction to Jackson Kayak took place in Cancun while I was attending a Roto Polymers conference during which time I saw their recently introduced fishing catamaran, kayak, and cooler being displayed to the attendees. Every one of these products was designed exceptionally well at every level of detail. I was extremely impressed with how

the design team optimally balanced form and function with every product feature. All the products were obviously manufactured by the same company, which skillfully unified all the products with a distinctive style, graphics, and aggressive color combinations within a variety of marbleized patterns. I think Jackson’s product line exemplifies great design by combining collective personal experiences with the product line, market vision, attention to detail, and outstanding engineering.

During my interview with Damon I asked him how kayaks and other watercraft products were developed, and he surprised me with his answer. Although the initial designs began conventionally, starting with a basic overall concept which was sketched and eventually partially developed in CAD, the remainder of the development was unique compared to current design development.

According to Damon, Eric Jackson and David Knight collaboratively develop the basic hull designs and an overall theme for the kayak. The hull design is then refined in 3D CAD with numerous iterations until a desired form is attained. This CAD model is then used to machine a physical full-scale foam

plug which is sealed, sanded, and refinished.

A fiberglass mold is fabricated from the plug, and eventually used to rotationally mold two to three prototype hulls, which are tested under actual use conditions. Jackson does not own or use large scale water flow tanks to test hull designs. These prototype hulls are verified by expert kayakers who provide first hand critical performance reviews based on use. Hull designs are modified based on suggestions for improving stability, maneuverability, rigidity, and the ability to withstand harsh impact forces experienced during whitewater activities.

Jackson employs some of the world’s best kayakers to evaluate the design, providing their personal comments pertaining to “feel” and performance. These completely subjective critiques are seriously considered by the design team to hone the design to an optimized level of performance. Damon informed me that Jackson is always improving designs with each new product introduction, which Jackson considers a prototype of the next generation product.

This endless pursuit of perfection has enabled Jackson to be regarded as one of the world’s best kayak brands. Since major improvements in many of the product lines have reached a plateau for the past twenty years, new product design improvements are now focused on subtle details, improvements in material specifications, and product branding. Jackson continually searches for resins with improved UV resistance, abrasion resistance, and impact strength. Jackson’s design team typically designs kayak hulls with a minimum of .150” up to .220”, which is quite a bit thicker than lower cost products, which range in thickness from .120” to .150”.

Jackson’s product lines are segregated into different divisions, which are staffed with

personnel familiar with the specific product line. In 2010, Jackson started a fishing watercraft division which introduced a river fishing boat. These products are surprisingly not designed using CAD, but are fully designed and developed by hand sculpting full scale foam plugs which are created by a very talented industrial designer by the name of Tony Lee. Tony brings a unique set of skills to Jackson with his experience as a surfer, industrial designer, and outdoorsman.

He works with individuals like Damon to transform a raw block of foam into a fully detailed functional pattern from which a production rotational mold is eventually cast.

These fishing boats are highly specialized since some are specifically designed for river fishing while others are designed for fly fishing. Design considerations which distinguish one type of craft from another include the type of body of water, deck features, hull design, and requirements, water conditions including waves or glassy surfaces, and wind conditions. These criteria must be balanced with tradeoffs of speed verses maneuverability which influence length, width hull shape, and keel shape, all directly affecting design.

Transforming a raw block of foam into fully detailed functional pattern from which a production rotational mold is cast.

Damon’s secondary profession as a hunter and fisherman provides him with special insights for designing fishing craft, which are highly influenced by his experience.

When I asked him how the Mayfly kayak fly fishing boat design was developed, he began by explaining one of the major problems experienced by fly fishermen is entanglement of casting line on boat decks.

Therefore, the design team was instructed to design a clutter free deck by eliminating all protrusions, which could entangle fishing line. Foot pegs, which are small ears that protrude from the gunnels, were eliminated

and all knob designs were changed to skirted geometry versus undercuts.

Tackle boxes were also located in areas that would not interfere with casting lines.

Identifying critical design requirements and creatively translating them into distinctive product features is what sets Jackson products apart from their competitors.

This design process requires a closelyknit team of cooperative and talented individuals working together with a passion for designing a high-quality product. A closer examination of the Mayfly kayak for example will underscore the near perfect balance of form and function. Every feature has a purpose, which has been deliberately designed and crafted to benefit the user while being aesthetically detailed to visually contribute to the entire product’s image.

The Mayfly kayak includes a custom designed seat, which was optimized with this particular craft. A tank well compartment

located behind the seat was designed to securely store a fishing crate, cooler, or gear bag. A pair of standing pads located in front of the seat have been designed to provide the fisherman with a slip proof surface when standing. Adjustable foot rests straddling the pads, provide the fisherman comfort during paddling. The bow of the kayak includes a Hypalon strap which was designed to secure and isolate paddles during casting. Jackson has been able to successfully private label this same product for Orvis with their own colors and graphics. The hull’s uniquely distinctive contours were developed to optimize paddling through water with a sharp V-bow and maximize stability with a wide center area. Jackson’s fishing kayak designs have been optimized for specific types of fishing including river, ocean, fly, big game, and even specific species of fish. These different conditions influence kayak design based on the distance one must paddle, fishing stance (standing or sitting), kayak stability, and even the amount of tackle used.

Jackson’s product line offers great examples of high quality rotationally molded products, which have been designed to optimize the benefits of the process, material, function, and appearance, offering customers high value.

Designed to optimize the benefits of the process, material, function, and appearance.

Jackson Kayak products demonstrate the importance of good design.

I hope this article demonstrates the importance of good design, which is much more than CAD work. Good design is not limited to adhering to basic design principles or being familiar with rotational molding design guidelines or even executing excellent engineering skills. Good design includes all of these skills plus understanding the end user and the market. Great products are designed by individuals or teams who share a common vision and culture. They require individuals to creatively seek design excellence without compromise or excuses.

Although technical skills are required at every level of development to translate concepts into real solutions, imagination, and vision are essential talents to attain great design solutions. Rotational molding has enabled Jackson to cost effectively offer its customers a diverse product line, but innovation, passion, and imagination have propelled it to the top of the market.

A company cannot expect to be an industry leader by simply offering the lowest cost

product or a carbon copy alternative to a competitive product. Market leaders must see an opportunity and intelligently invest in good design to establish themselves as number one.

I hope this article has inspired you to reach for excellence in your next product and make the proper investment in market research, design, tooling, and production quality.

Contrary to most people’s misconception, design is NOT limited to CAD work. Design requires thought, knowledge, experience, passion, intelligence, and imagination. CAD is simply a means to an end. The Jackson product line exists because of its talented staff of people and the unique benefits offered by rotational molding. Rotational molding is the only manufacturing process that can provide large high-quality products with complex shapes as a single part cost effectively. Just imagine what can be done with your product line when you combine vision, imagination, and excellent engineering skills with this versatile process. The boundaries are truly limitless.

RS Sailing Teaching the World to Sail

by Martin Spencer, Unique Roto

RS Sailing, the world’s largest small sailboat manufacturer, launched the RS Feva sailing dinghy in 2002. Developed by the firm as a double-handed sailing dinghy for youngsters, the craft was designed by Paul Handley and moulded by Rototek Ltd in the UK. The Feva was recognized by World Sailing as an international racing class in 2003 and was the first rotationally moulded sailing dinghy to attain that distinction. Several years ago, rotational moulding expert Persico started working with RS Sailing to aim for the highest-quality and most cost-effective mouldmaking.

RS Feva was the first in the RS range of rotationally moulded dinghies, which are now in use all around the world. The class has many thousands of users worldwide with more than 27 national class associations and annual world championships.

Key decision to go with rotomoulding In 2002, most sailing dinghies raced at the club level were manufactured from glass fibre. They were quite expensive and prone to be easily damaged, particularly when

used by young inexperienced crews. RS Sailing and Paul Handley took the unusual step of choosing rotational moulding as the preferred construction method. This gave them a much tougher damage-resistant hull, which was ideal for training and introducing youngsters to competitive sailing. The threelayer Comptec hulls gave the boats a stiff durable hull with a weight comparable to many glass-fibre boats.

Hull construction: stiff and impact-resistant yet lightweight The hulls of all these boats are rotationally moulded with three-layer foam sandwich construction to provide the stiffness required for competitive sailing, while keeping them light and easy-to-handle. The outer layer is high-density super-linear polyethylene to produce a high-gloss, pinhole-free, scratchresistant and very stiff moulded surface.

The middle layer is a specially formulated polyethylene foam to give maximum stiffness, whereas the third layer is a lower density polyethylene to ensure integrity and improve the impact resistance of the overall sandwich construction.

Rotational moulding provided a much tougher, damage resistant hull.

(Top-left) CNC machined moulds for the stern and hull (Top-right) RS Cat 14

Persico Rotomoulding offers its expertise The original RS Feva was produced from a cast aluminium mould made from a handfinished fibreglass model and has been in use ever since. As the range progressed, Persico began working with RS Sailing to achieve the best quality moulds possible. Since the dinghies are one-design class racing boats, the dimensions need to be accurately reproducible. In the early days, the design model and tool were hand finished, so there were no accurate 3D files for the designs.

Later on, 3D CAD was used for designing, with models and prototypes CNC machined from foam. The moulds were then cast in aluminium and hand finished.

Precision mouldmaking The latest generation of dinghies is fully designed in 3D CAD. Persico engineers work with this data to produce CAM (computer aided machining) files, which are then used

by Persico moulding specialists to machine the hull and deck moulds from large solid blocks of aluminium. The moulds are finished to a very high standard with much of the surface highly polished. Next, the machined tools are mounted in steel frames, and detail is added to allow the moulding in and fitting of many special components, including numerous specifically designed, in-moulded threaded inserts.

Then, the completed Persico tool is used to rotationally mould the hulls on a large rock-and-roll oven at Rototek, using very sophisticated software to ensure that the 3-layer sandwich construction meets the

superior quality standards required. Internal and mould temperature monitoring are used to control and record the process at every stage. This gives full process traceability on every hull. Once moulded, the hulls are subjected to rigid checks on wall thickness and class dimensional tolerances in order to be acceptable for sale and competition.

Latest generation moulds: longer-lasting yet cost-effective The latest CNC-machined moulds for the RS Tera and the RS Zest dinghies will be longer lasting, while maintaining the finish and tolerance standards better than the original cast aluminium tool that launched the range back in 2002. RS Sailing and Persico have cooperated on many other sailing dinghy moulds, making RS Sailing one of the most comprehensive and best-selling ranges of rotationally moulded sailing dinghies available worldwide. The cost-effective construction method produces boats that are ideal for training and introductory racing, thus opening up sailing to a much wider audience.

The collaboration between RS Sailing, Persico, and Rototek on the RS Feva range of boats has helped RS Sailing become a leader in sailing training and introductory racing across the globe. The range includes dinghies from 2.87 m to 6 m in length and can accommodate crews of just one child up to 4 adults. rssailing.com persico.com rototek.com

releases the potential of the production process to create something unique in polyethylene.

Rotational molding is one the Italian excellences.

Lorenzo Bozzoli brings woven leather to life through rotational molding.

The new concept of the brand is thinking about the future in the key of a contemporary and sustainable luxury. SLIDE brings the ‘Made in Italy’ concept all over the world, thanks to three important factors: the internal production, the collaborations with famous Italian designers, and the inspiration from ancient Italian tradition.

Rotational molding is one of the Italian excellences and SlideÂŽ engages its research to find an innovative processing production process for polyethylene. Thanks to the development and internal engineering, Slide presents a collection that broadens the boundaries of design. Thanks to refined texture and amazing finishing, SLIDE

The first factor is the real Made in Italy: since its birth, in 2002, Slide established its factory near Milan, Italy, and chose all its suppliers from nearby areas. The second factor is the Italian genius: the new collection is created by Italian famous designers, such as Fabio Novembre, Paola Navone, Lorenza Bozzoli, and Roberto Paoli. The third and most important factor is that SLIDE is inspired by Italian craft work.

SLIDE staff believes in polyethylene potential and loves the environment. Indeed, polyethylene is an unbelievable versatile material, perfect to create countless possibilities and have a strong potential.

Thanks to these features, SLIDE found new production methods that can change the perception of the material directly during the production, and not only on the surface in post-production. Furthermore, polyethylene is a green material: every product is 100% recyclable and some colours of the catalogue are recycled.

sentence, which also bears the entire description that the designer himself makes of his product: “Sometimes a spin is needed to make a pure shape vibrate�.

Thanks to the ARMO Showcase, we are pleased to highlight the two best novelties presented by SLIDE in 2019: Spin Hanging Lamp by Fabio Novembre and Mara Collection by Lorenza Bozzoli. These two products show the world the importance of research on material and the techniques of rotational moulding.

F. Novembre: First of all, it must be said that Italy in the plastic field is one of the world excellences, thanks to the Nobel Prize winner Giulio Natta studies. The rotational moulding process has an interesting history because it was created for the creation of empty, containment tanks. Only later came the designs with all its aesthetic claims.

For the first time, Fabio Novembre collaborated with SLIDE, and together with the engineering office of Slide gave birth to Spin, a thin lamp with an elegant design that is simply unique and ideal to light up with amazement and discretion in settings of any size, thanks to its modularity.

C. Bolognino: When was the first time you used rotational moulding in your career and for which project?

Spin Hanging Lamp comes from the twist of a square-based parallelepiped element. The modularity allows the design to obtain long and sinuous elements that can vary in terms of composition, based on the aggregation method. Fabio Novembre’s inspiration when he designed the shape was the following

Fabio Novembre told us why he chose to work with rotational moulding and his experiences: C. Bolognino: Rotational moulding is a special technique that has disadvantages and advantages. What do you think of this process?

F. Novembre: For Him & Her Seats. It was a very long process in which we started from casts of real bodies and then landed at the 3D scan, and finally at the mould. But we really reached a body plasticity in a strict sense.

C. Bolognino: Spin is your latest project for SLIDE, and it brings rotational moulding into the lighting sector. Was it a complex process?

F. Novembre: Spin takes full advantage of the rotational technique with an interesting point of view. In fact, in addition to the twist, the lamp has recesses along the longitudinal axis that naturally should be in shadow, or at least darker than the more external profile.

But thanks to the work done by the SLIDE engineers, we were able to reverse the perception at its remaining brighter inside.

The effect is magnificent.

Another particularity of Spin is the special mosaic finish that can be made on request.

To further enhance the lighting effects of the hanging lamp, Fabio Novembre and

SLIDE also worked on the raw material for the production process. In this case, polyethylene is not in powder but in bigger pearl, that melt together during the production process and remains visible.

The second amazing product we want to discuss is Mara Collection by Lorenza Bozzoli. Woven leather comes to life in all the texture of the Mara Collection structure, consisting of a Sofa, an Armchair, and a Pouf. Lorenza Bozzoli’s years in the fashion sector lead her to reproduce also from plastic material the imperfect and tactile interweaving typical of leather hand manufacturing. The unique texture is combined with the soft cushions in waterproof fabric suitable for outdoor use. The comfortable seat makes the Mara Collection ideal for rooftops, gardens, and interior and outdoor contract projects.

Another amazing specification, created for the collection, is the Mahogany Leather and Saddle Leather colours. These two new colours are obtained thanks to a special polyethylene mix of different powders that reproduces the colour of leather and enhances the weaving of the structure. The woven leather comes directly to the mould.

product, for indoor spaces.

To achieve this goal, as well as in the careful study of shapes and sizes, I concentrated on creating a texture that resembled braided leather, covering the perception of plastic material of the rotationally moulded products and transmitting the warmth of the natural material.

The weaving of the leather is reproduced thanks to an exclusive texture on the mould, so Mara Collection can’t exist without its unique texture. This is the object lessons about the continuous research on production methods that can change the perception of the material directly during the production and not only on the surface in postproduction.

SLIDE is very proud to create a new perception of plastic material, respecting market trends and pushing to create richer and more refined furnishings, perfect for outdoor and indoor. Indeed, today, the indoor spaces are often divided from the outdoor ones only by a glass window. Not forgetting its first soul, SLIDE creates a collection that changes the perception of plastic and enhances all the potential of rotational moulding. The new essence was possible thanks to the collaboration and imagination of two very important Italian designers, such as Fabio Novembre and Lorenza Bozzoli.

C. Bolognino: In a short interview, I asked Lorenza Bozzoli to talk about her inspiration when she decided to create Mara Collection:

World-renown designer Lorenzo Bozzoli

L. Bozzoli: The idea of the Mara Sofa was to create an object that could be placed in the outdoors as well as generally for this type of 2019-2020 ARMO Rotational Moulding Product Showcase

Creating New Roto Applications with Matrix’s Advanced Polyamide 6 (PA6) Powders

by Martin Coles, Matrix Polymers

The late Professor Roy Crawford once said that “..the full potential of the rotational moulding process will never be realised until a full palette of plastics materials is available to the designer.”

This is a comment that Matrix Polymers took to heart and at the ARMO Rotomoulding conference in Nottingham in 2015, the company presented their vision for the future of the industry – https://www. youtube.com/watch?v=mGf2RyH63bI It is clear that the industry has been ‘held back’ by the almost total dominance of Polyethylene and the lack of easy to use and cost-effective alternative materials. Whilst polyethylene is a fantastic, tough, forgiving to use, easy to grind, readily available, and very low-cost material, it still has a lot of limitations – such as poor scratch resistance, lack of stiffness, is difficult to decorate, and has poor high temperature resistance.

Air Duct

So, Matrix announced a new focus on the

60 2019-2020 ARMO Rotational Moulding Product Showcase

Research & Development of alternative nonpolyethylene materials for rotomoulding.

This was backed up with new investment in plant and equipment, such as cryogenic grinding to produce powders out of difficult to grind materials, to help make this vision a reality.

During the development of new materials, a big emphasis has been made on making them practical, easy to mould, and able to be used in conventional Rotomoulding machines.

One of product groups that has come out of this programme is Polyamide 6 (PA6) powder, which has now become fully commercialised. There are two grades available, a standard version and a higher cost impact-modified one. Both, with care, can be moulded on conventional rotomoulding equipment and do not require any complicated additional processes, such as drying or needing an inert atmosphere or blanket within the mould. The material

can also be moulded in traditional steel or aluminium moulds.

A new high-performance application for a high performance PA6 material A luxury European car manufacturer was looking to have an air duct produced by rotomoulding for their new and very powerful iconic sports car. They turned to Maus GmbH, the premier rotomoulding mould maker in Germany, to help develop the application and CNC mould, and Maus involved Matrix in discussions regarding the best material to use for this new product.

The ducting is needed to collect cold air and deliver this to the ceramic braking discs, so they do not overheat during extreme braking.

The production volumes are small, but the requirements for aesthetic look, tolerances, and performance are very high.

The mouldings have to withstand high temperatures, especially near the ceramic brakes, and they have to be tough, stiff, be light-weight, and be made to very tight and exacting tolerances.

Additionally, the inner surface of the mouldings is fully visible at the front of the sports car, so they need to be as black and glossy as possible.

Matrix Polymers compound powder Revolve PA HIU Black

Maus manufactured the CNC machined aluminium moulds

and produced the jigs for CNC routing of the openings, as well as providing milling programmes for the post moulding operations.

The impact modified black version of Matrix’s PA6 material, Revolve PA HIU, met all the criteria demanded by the OEM and underwent rigorous testing before the start of production.

High operating temperatures Being able to cope with continuously high operating temperatures was a critical requirement for this application and PA HIU scores well in this area. The physical properties of all polymers are affected by temperature. At elevated temperatures they become soft and lose strength and rigidity. Figure 1 shows the tensile modulus

Figure 1 High Temperature Tensile Modulus (stiffness) for Revolve PA HIU

(stiffness) of PA HIU at temperatures ranging from 100 to 150 degrees C. Even at 150 degrees C this material still performs well and retains good rigidity. In comparison, any polyethylene material at this temperature would have completely melted.

Great stiffness, shot-weight reduction and light-weight parts Another crucial requirement was that the material had good stiffness so that parts can be made with as little material as possible to keep weight down to a minimum.

This is a common request in the automotive sector.

PA HIU is an extremely stiff Rotomoulding material and has 4 times the flexural modulus (stiffness) than a typical medium density polyethylene (at ambient conditions – 23 degrees C, per ISO 178) – see Figure 2. This means that mouldings can be made with the minimum of powder, saving weight, and cost.

Figure 2 Flexural Modulus (stiffness) for Revolve PA HIU, compared to LLDPE

Figure 3 Impact Strength for Revolve PA HIU compared with LLDPE (ARM test at 5mm wall thickness)

It is worth mentioning that this stiffness and light-weighting potential gives the rotational moulder the opportunity to reduce wall thicknesses, which in turn can improve the value proposition to the end user, particularly in the automotive sector.

Good toughness and impact strength Most rotomoulding applications require a good level of toughness and impact strength and this application is no different. PA HIU has a comparable impact strength to general purpose medium density polyethylene at 23 degrees C. It is less good at minus 40 degrees C, but the performance is still acceptable – see Figure 3.

How easy is it to mould PA HIU? Matrix has designed this material to be easy to Rotomould and it does not require

any complicated processing and there is no need for an inert atmosphere. Revolve PA HIU is pre-dried and can be moulded on conventional Rotomoulding equipment and with traditional steel or aluminium moulds.

As with any material it is very important to find the right moulding conditions to achieve optimum mechanical and physical properties. It is best to monitor the internal air temperature to ensure that the powder has fully sintered and melted out. In internal testing on Matrix’s Ferry 190 carousel machine in the company’s Rotomoulding Technical Centre in the UK, it was found that optimum properties were achieved with a Peak Internal Air Temperature (PIAT) of around 230-235 degrees C – see Figure 4.

This material flows well and as this application demonstrates, mouldings can be produced with good wall thickness distribution and internal surface finish with minimal pin-holing.

62 2019-2020 ARMO Rotational Moulding Product Showcase

New materials help create new applications Whilst Matrix’s Polyamide 6 (PA6) powders have been developed primarily for the automotive sector, this material can also be used for other applications. As well as the key features of high temperature resistance (140-150 degrees C), very high stiffness (4 times the stiffness of medium density Figure 4 Internal Air Temperature trace for Revolve PA HIU – polyethylene), and the fact Matrix Tech Centre that they can be moulded on conventional rotomoulding equipment, these materials also exhibit other benefits such as high scratch resistance and paintability.

Opportunities include the substitution of Liquid PA6 for making fuel tanks and the replacement of existing rotomoulding products made from other materials. There is also a whole world of products being made from traditional materials, such a steel, which require stiffness, hardness and high temperature resistance that have up until now been beyond the scope of rotomoulding.

Matrix Polymers is happy to work with any rotomoulders or OEMs about potential new rotomoulding applications and to listen to thoughts and ideas about new materials.

Creating new materials must be the way forward for our industry and Matrix is committed to investing in Research and Development to make the company’s vision become reality.

Persico gets to the Core of the Problem through Smart Rotomoulding

by Persico Industrial

In the last decade, manufacturing applications for composites have been expanding rapidly.

Composites now make up numerous parts in aeroplanes, racing cars, and many other vehicles, and are commonly used in the construction sector.

these technologies can produce only a solid single skin composite. If hollow components are required, they must either be assembled from multiple parts or moulded around a core of some type, similar to the casting process for metals.

Along with automotive, industrial, marine, and aerospace, Persico Group is engaged in the composites industry, where it has been providing design, tooling, and moulding presses since the 1970s. The Group is continually working on developing innovative solutions to yield composite parts with better performance and lighter weight.

Composite core production processes During the manufacturing process, composite material is typically wrapped around a shaped core to give the composite the desired contour and support while it is being cured.

In some processes, the core needs to be rigid to withstand moulding pressure and temperature, whereas, in others, a flexible core is used with balanced pressure. Once the composite is cured, the core needs to be sufficiently lightweight, if it is to remain inside the finished product; otherwise, it has to be removed either by collapsing and extracting it through a hole in the composite or by dissolving it away.

Numerous composite production technologies Composite parts can be made using a number of different production methods: RTM (resin transfer method), vacuum bag/autoclave, vacuum infusion, compression moulding, and filament winding, to name just a few. Most of

Persico researchers have rotomoulded cores from a variety of thermoplastics, as shown in the photo.

Persico Smart DTH rotomoulded cores Some years ago, Persico realized that rotational moulding had the potential to help solve many of the problems associated with hollow composite parts. Hence, the Group’s composite and rotational moulding engineers have worked together to design and test diverse types of core that can be used with different composite production methods.

The engineering team quickly determined that conventional rotational moulding machines

moulding process, enabling the use of many difficult-to-mould materials.

Persico’s R&D engineers have tested numerous potential core materials in house.

The cores are moulded and then wrapped or coated with composites; after curing, the cores can then be removed for final composite product testing.

would have great difficulty consistently moulding the various available core materials with controlled wall thickness. However, they believed the Persico Smart Rotomoulding Machine – developed through the cooperation of Persico Rotomoulding and Persico Automotive engineers – would be ideal for the purpose. The Smart Machine uses electric DTH (direct tool heating), allowing mould heating to be divided into zones, with each zone separately monitored and controlled. The separate temperature zones ensure accurate and repeatable control over the wall thickness of the moulded parts. The internal void in the tool can also be subjected to pressure, vacuum, or inert atmosphere during the

Persico rotomoulded cores now in production Commercially, Persico has produced tooling and started up the production of rotomoulded cores for a well-known supercar brand.

The Group has also teamed up with seven other European companies to engineer a process (HP-RTM) to manufacture composite motorcycle parts using water-soluble rotomoulded cores.

Persico has several Smart Machines around the world producing cores on a daily basis for composite production. It is currently working with a high technology component manufacturer on a Smart Machine and multiple DTH tools for specialized cores.

wound CNG (compressed natural gas) tanks with varying degrees of success, allowing for consistent moulding of polymer around incorporated metal components. With the advent of hydrogen fuelled vehicles, the problem of gas migration through the moulded plastic has become more difficult to solve. Persico DTH technology on a Smart Machine permits thin layers of different materials to be moulded, so as to provide the required barrier properties.

Persico rotomoulded cores for all needs Persico has tested many materials – including EVOH, PVA, special PE grades, PP, ABS, PA, and PBT – for cores moulded with DTH electrically heated tooling and machines.

By exploiting the properties of these varied polymers, Persico specialists can produce a wide range of different cores:

• Cores for LP-RTM processes where the cores are inflated to withstand pressure.

• Cores to be dissolved away from the inside of the cured part using water or chemicals (see photo).

• Cores designed to collapse under a vacuum to allow for removal through holes in the finished composite parts.

• Low cost cores using very thin layers of standard materials that can then be left inside finished products.

• Cores for prepreg in autoclave systems to withstand moulding and curing pressure.

Persico: continuously innovating production technologies The possibilities are endless and, thanks to the collaboration among Persico’s departments and divisions, advanced techniques from many different industries are being brought together to engineer new solutions.

Persico Group is leading the way in many specialized technologies to provide innovative manufacturing solutions.
