For The Rotomolding Industry

Let Our Customers Speak for us.

We just wanted to let your company know how pleased we are with the Powder King® Super Mega. Its performance and output has been unparalleled to any other machine we have tried. We really enjoy the simplistic design and function of the machine and the EC200 control makes it both efficient and user friendly. We are in the process of writing a new project to hopefully purchase more Powder King® pulverizing systems.

We are extremely happy with all of our Powder King® systems: the Direct Drive, High Volume Mill Air Cooling and now the new EC200 Control System have clearly advanced Powder King® light years ahead of their competition. — Mike G.

FROM THE

PUBLISHER Susan Gibson, JSJ Productions, Inc.

Leadership: How it’s changing! To say that 2020 is year of disruption and change is obvious. We have experienced exponential change in our daily lives from education, managing our health, and working from home to simple social norms such having dinner with family and friends. We are undergoing monumental change, and we are adapting. Virtualization of the workplace, online learning, virtual health, and e-commerce lead the way. We would have, under more normal circumstances, anticipated years to make such big culture-shifting changes, however we’ve seen them take shape in just months. The backdrop at play is that the conditions for accelerating change have been building for years. Advancement in information technology, automation, human interconnectivity, artificial intelligence, and the effects among them, have created a new reality where change is much more rapid, continual, and felt by all. COVID-19 has laid bare a ‘new normal’ of life. To this end, leaders must be thinking this may well be defining our future, and leadership may well be defined by the ability to navigate this new reality. Welcome to the “Leadership” issue of RotoWorld®. Speaking of leadership, we are excited to present Centro Inc.’s story of evolution on the event of the company’s 50th year anniversary. I think you will enjoy reading President & CEO Brian Olesen’s compelling story about how this company has navigated the past 50 years and continues to grow and get better. The Iowa-based rotomolder started with humble roots and has grown into the largest custom rotational molding company in the USA. And, now Centro Inc. is in Brazil. Included in this issue are two important articles on rotomolding technology. Queen’s University researchers, led by Karem Akoul, offer all aspects of their collaborative governmentsponsored project between with CP Cases. CP Cases is a Londonbased company that manufactures high performance protective cases for the transport of high-value equipment for the media, entertainment, and commercial industry. ARM Executive Director, Dr. Nick Henwood, writes the first of his series on “What Rotomolders need to know about Polymer Chemistry”. Henwood states, “Rotomolders tend to be more mechanically minded than chemically minded, however knowledge is power and there is great benefit from a sufficient understanding of polymer chemistry, especially when they are receiving conflicting information from different suppliers.

Our Departments are instrumental to RotoWorld®. I hear from our readers all the time about how you follow certain columns and share this information with your staffs. Please take a moment and respond to these authors so they/we can offer more of what helps you in your business. In this issue, Industry 4.0 author Rob Miller calls upon you to let him know your questions, issues, and problems with regard to Industry 4.0. This is so Rob can further develop the most meaningful ‘Relationship Capital’ to benefit the industry. This is a vital topic for the future of our industry so get engaged with Rob and see what is to come! Finally, as this year rolls to a close we will be offering a survey to our readers by year end to help us better understand what is on your mind and what topics and information we should work toward providing in the coming years. We are very appreciative of our solid readership, and we are here to serve you with the best RotoWorld® magazine in print and online possible. Please keep this in mind when you shop for products and services and make your first contacts with the companies that support RotoWorld®. Thank you and wishing you safety and good health!

We are undergoing monumental change, and we are adapting.

UPFRONT United States (USA), 2020-09-30 – Emerson: Emerson Launches Unique Heat Staking Technology to Meet Growing Demand for Complex Plastic Parts Branson™ GPX platform provides greater design freedom by enabling high-quality joints and superior aesthetics in a range of challenging applications

DANBURY, CT, USA — Emerson has introduced new

heat staking technology designed to give manufacturers greater design freedom by enabling them to join more complex, delicate and sensitive components to plastic moldings. Using a unique pulse staking technology that optimizes the heat staking process, the Branson™ GPX platform produces high-quality joints, superior product aesthetics and energy savings in increasingly challenging applications. Electronics, automotive, and medical device manufacturers must produce more creative designs to meet rapidly changing market demand. This has led to an increase in challenging heat staking applications involving parts with more complex 3D geometries, closely aligned features and fragile or heat-sensitive components, such as soldered components or sensors, and using a greater number of blended, glass reinforced, chromed, and metallicized plastics. The Branson GPX platform uses PulseStaker technology to provide instantaneous heating and cooling, with adjustable cycle times for optimized, low energy heat staking. The process creates no particulates or burn marks, and enables more delicate and sensitive parts, such as those with embedded electronics, to be joined with consistently high-performance finishes. The advanced technology is suitable for all heat staking applications, including those with thermoplastic materials and metalized coated parts. A wide range of heat staking tip designs, which can be adapted to meet any stake welding requirement, and the ability to stake multiple points simultaneously provide manufacturers with greater design freedom. “The automotive, electronics, and medical industries require more complex, delicate, and sensitive components to be joined to

plastic moldings,” said Priyank Kishor, global product manager for Branson products at Emerson’s Automation Solutions business. “The unique heat staking process that the Branson GPX platform provides helps to meet this demand and offers manufacturers a broad range of benefits, such as superior product aesthetics and reduced energy use.” For more information on the Branson GPX platform, visit www.Emerson.com/Branson. https://www.emerson.com/en-us/ news/automation/20-09-branson-gpx-platform

TRAVEL UPDATES Which Countries are Reopening for Meetings? Here Are the Latest Updates from Around the World As of press time, Belgium and England have announced national lockdowns intended to curb the spread of coronavirus. Similar restrictions were introduced in France and Germany last week. Many parts of the world continue to battle new COVID-19 outbreaks, leaders have paused the reopening process and, in some cases, put in place new restrictions. Mexico and Canada have extended the closure of their borders with the United States until at least November 21. Recent spikes have led many European countries to reintroduce measures to curb the spread of infection and reimpose travel constraints on their neighbors. In response to Belgiumâ&#x20AC;&#x2122;s rise in cases, the countryâ&#x20AC;&#x2122;s leaders have introduced new restrictions. From November 2 to December 13, nonessential shops and businesses will be closed. Employees are encouraged to work from home and public gatherings cannot exceed more than four people. England also is expected to enter a four-week lockdown from November 5 to December 2. Bars and restaurants will only be allowed to serve take out. Gyms, theaters, salons, and nonessential retail businesses must shut down for the time being. On October 30, France entered a nationwide lockdown that will last until December 1. During this time, gatherings are banned, and nonessential businesses, including bars and restaurants, will close. Residents are required to fill out permission forms whenever they leave home. Meanwhile, a partial lockdown in Germany began on November 2 and is expected to remain in place until November 30. Gatherings are limited to no more than 10 people from a maximum of two households. Restaurants can only serve takeout, while bars, theaters and gyms will be forced to close. Italy implemented new restrictions on October 26 that are expected to last until November 24. Bars and restaurants must close by 6 p.m., and people are required to wear masks outdoors. On October 25, Spain declared a state of emergency and ordered a nationwide curfew. Regional leaders can modify the curfew and restrictions. Prime Minister Pedro SĂĄnchez will ask Parliament to extend the state of emergency until May. Further north, Wales entered a 17-day lockdown on October 23, and Ireland imposed its highest level of coronavirus restrictions on October 21. The rules, which prohibit all indoor and outdoor organized gatherings, are expected to last six weeks. The Netherlands government has ordered a partial lockdown beginning October 15 that is expected to last at least four weeks and includes new restrictions on bars and restaurants, gathering limits, and face-mask requirements. The government of the Czech Republic reimposed a state of emergency on October 5 and also has lowered gathering restrictions. On October 13, European Union countries approved new travel guidelines that unify testing and quarantine regulations to simplify

travel between the member nations. As part of the new approach, the E.U. has created a map that displays the COVID-19 risk levels throughout Europe, based on a traffic-light system. The map will be updated each week by the European Centre for Disease Prevention and Control. Regions will be colored green, orange, or red, depending on the total number of new COVID-19 cases per 100,000 people over the past 14 days, as well as the testing rate and test-positivity rate for the preceding week. Regions will be colored gray if not enough information is available. The map will be used to determine travel restrictions, including quarantine or testing mandates. For example, those coming from green regions will not face any travel restrictions, while travelers from orange and red regions can expect some restrictions. As some destinations have largely contained the spread of COVID-19, a few have announced plans for again allowing business events to take place. On October 8, the Hong Kong Tourism Board announced it would launch standardized hygiene and anti-epidemic protocols for tourism-related industries, in partnership with the Hong Kong Quality Assurance Agency. Beginning October 1, Singapore approved business gatherings of up to 250 participants, while Dubai reopened for international meetings on the same date. Conferences and exhibitions were also expected to return to the United Kingdom on October 1. A number of tourist destinations have moved forward with their re-openings, including Costa Rica and the Dominican Republic, which recently announced new policies making it easier for travelers to visit. www.rotoworldmag.com 25

“If you build it, they will come”

THE CENTRO STORY ON TH THE 50 ANNIVERSARY Brian Olesen, Centro Inc., President & CEO Long before the iconic movie Field of Dreams proclaimed “if you build it, they will come” regarding a baseball field in an Iowa cornfield, Dick Rozek bet on that same dream in a different Iowa cornfield in Oxford, Iowa. Betting that if he could build a company on a basic concept of being the best “they” (customers) would come. And come they did. After a brief MLB pitching career with the Cleveland Indians (yes, it is true he threw the first homerun ball to Mickey Mantle at Yankee Stadium) and a successful manufacturing representative career, Dick went all in on his dream to start Centro, Inc. in 1970 as a custom rotational molding company. Today, 50 years later, Centro, the largest custom rotational molding company in North America, a juggernaut as an international enterprise, employing nearly 1,000 people with 10 locations in 3 countries with deep roots in the Iowa soil while still adhering to the belief of picking one thing and always striving to be the best at it. 1970’s Fighting for Survival Focused on converting fiberglass products for John Deere Des Moines Works proved a great application for rotational molding, but the recessionary business climate fueled by the energy crisis proved challenging to the start-up business. With banks tightening lending standards, cash to fund the business just wasn’t available. In order to survive Dick sold debentures to friends and family in order to make payroll. Crosslinkable

polyethylene emerges as a material opening a major new application to rotomolding with the John Deere snowmobile fuel tanks being one of the first major applications. The crisis passed, funding was secured, and Centro was ready for growth.

Dick Rozek hitting the tank with what looks like a bat at the original Oxford building

In the late 1970’s Dick’s son Gary joined the business and as he likes to say, “learning the business from the ground up started by cleaning the restrooms, trimming parts, and running the McNeil molding machines.” It wasn’t long before Gary could see the potential that rotomolding and Centro could be and was ready to create the roadmap and vision of what it was to become.

www.rotoworldmag.com 27

Dick was a true entrepreneur and maintained that spirit of taking risks to start and grow the business. Gary had the vision and was the detailed operator that together propelled Centro’s future. Both believing that the foundation of any good business includes valuing the Associates, believing in long-term mutually beneficial relationships with their customers, suppliers, and communities. 1980’s “In like a lamb out like a lion” In the early 1980’s the farm crisis hit Iowa, Centro and the rest of the agriculture community extremely hard. Again, Centro was in a fight for survival. The company faced a pivotal crossroad and a need to diversify its business. The first step Dick and Gary pushed was expansion into the lawn and garden industry by opening a new facility in Horicon, WI to serve that market in 1984. It was clear to them, especially in rotomolding, that a proximity relationship with your customer or market is critical in order to successfully diversify, a concept that would later be perfected. They also saw an evolving need for more technical part molding and taking rotomolding from tanks to more engineered applications, which included a backhoe loader roof, interior cab ducts and dashes, which were all new territory at the time and was pivotal to the evolution of Centro into a technical parts molder for industry leading O.E.M. customers. Marching into the 1990’s believing a single, strong focus on custom technical rotational molding, in a proximity relationship with the customer would propel the business forward.

1990’s Roaring Growth but Centro loses its founder and original facility Building on the success and focus of the previous decade the 1990’s began by embracing supplier integration as the next tenet of the Centro business model. Centro’s evolving engineering strength for the technical moldings developed further by providing on-site engineering and development for customer design integration. Centro’s engineering team worked within our customers facilities to develop, design, and test the award winning and patented design conversion of John Deere Harvester corn points and decks. It became clear the power of early integration with design produced rotomolding cutting edge products and functionality. It wasn’t long after the entire industry’s combines harvesting points and decks were rotomolded. Centro built and moved to the corporate headquarters and flagship manufacturing facility in North Liberty, IA just a few years before a devastating fire consumed the founding facility in Oxford, IA. A snowy late winter followed by a rapid thaw and freeze caused a partial roof collapse over an electrical junction box which was the source of a complete loss of facility, fixtures, and molds, but fortunately no personal injuries. It’s here however that the Centro spirit supported by the rotomolding industry sprang to action. Mold builders Rivers Metal Products, Lakeland Mold, Viking, Wheeler Boyce, and Kelch all responded with unbelievable heroics building molds that normally took 6 weeks

ARM 2017 Product of the Year – Intimidator GC1K Series 4x4 Sports Utility Vehicle, which includes 11 rotomolded parts.

in 6 days. Through it all, Centro supported by many, were able to meet all production obligations without shutting any customer lines down – a devastating loss mobilized into an unbelievable successful recovery effort. Centro’s sales rose from $10 million in 1990 to over $50 million by the end of the decade requiring expansions in North Liberty, a brand new facility in North Carolina, a joint venture operation in Monticello, IN with Donaldson Company, the introduction of a focused factory in Valley City, ND, and shortly thereafter the second in Thibodaux, LA. The focused factory concept targeted the biggest waste in rotomolding of large parts – handling, packaging, and freight by putting a Centro machine and Associates in the customer facility so that Centro produced parts can be fed directly to the customers production line. This lean concept would take Centro to the next level of integration with the industry leading OEM customer base. 2000’s After the robust growth and expansion in the 1990’s, the 2000’s began with 9/11 and the resulting recession. A very familiar pattern continued; rapid sales growth, increase in capacity and then a deep recession which put an additional strain on the business. To emerge from these challenging times Centro applied Lean Manufacturing concepts and introduced Liquid Nylon rotomolding to North America. Investments were also made in technical skills development, as well as diversifying revenue sources using the extra capacity from the downturn.

Gary Rozek

Centro was evolving into an engineering company that rotomolds including a patented process called RotoLoPerm™using three-layers of materials to meet EPA and CARB emission requirements for gasoline fuel tanks. A manufacturing process to deliver the three-layers was also developed and patented. The RotoLoPerm™technology that Centro would license to other rotomolding companies that continues to this day. During this decade Centro expanded its North Carolina facility and opened 2 more focused factories in Ankeny, IA and East Moline, IL, to meet the growing demand for the technical products. In 2007, after 17 years with Centro, I became President and in 2008 CEO while Gary remained in the business as Chairman of the Board. During this period the Great Recession hit affecting the overall economy at the same time a 500-year flood devastated our local area delivering an unprecedented one-two punch to www.rotoworldmag.com 29

Future While much has changed at Centro and in the world in those 50 years, the fact remains the rotomolding industry hasn’t. Material choice, labor intensity of the process, machine design, and the overall paradigm is much the same as it was when Centro started. Despite that Centro and the industry has prospered. Rotomolding today, even in its similar design, offers value to many products, designs, and applications which makes change difficult. If we are going to continue to drive our business and industry forward, we need to embrace the many challenges that face Centro and the rotomolding industry. Productivity, automation, manufacturing plant environments, skilled and unskilled labor, Industry 4.0, material choices, and the perception of plastics are just some of the issues that need to be addressed. We are fortunate to have an industry association (Association of Rotational Molders) that can continue to provide a platform for collaboration for the betterment of all. To close, the challenge for any enduring business is to be true to your roots, culture, and the other elements that define and make a business successful while adapting to an ever-changing business landscape. For Centro we harken back to our field of dreams and founder to appreciate our successes, value our relationships, and strive to be even better tomorrow. On this 50th Anniversary we celebrate the fact that Dick did build it, and they did come – for over 50 years!

our Associates, community and business. Through it all Centro prepared for the future rallying to find a way for the business to improve during this downturn and even found a way to grow. 2010’s More Growth, More Expansion The 2010’s was a great decade for Centro’s core markets and continued growth and facility expansion was required. A focused factory in Waterloo, IA opened in 2010 and expanded twice after. Beaver Dam, WI opened a 60,000 sq/ft repurposed Green Giant facility to a 3 machine rotomolding operation to increase capacity. Many of Centro’s customers are multinational and they saw great opportunities for expansion in the BRIC (Brazil, Russia, India, and China) countries and encouraged Centro to follow them with Centro’s rotomolding capabilities. After years of evaluating BRIC country opportunities Centro decided on Brazil and took the same value proposition to Horizontina, Brazil in 2014 (and expanded in 2020). Centro also opened an engineering office in Banbridge, Northern Ireland. While Centro is consistently ranked by Plastic News as the largest custom molder in North America, a recognition that has never been the objective, but as Gary Rozek always drove home it is a result of doing a lot of other things very well – the single and strong focus, build products close to use, the long-term relationships with customer, vendors, and Centro Associates.

Design Details How many times have you seen a great concept rendering for a new product and experienced major disappointment when you saw the first production assembly based on that inspirational design? It happens frequently so you shouldn’t feel alone. There is an adage; “The devil’s in the details” which becomes much more significant as one gains experience designing and developing products. When I was much younger, I didn’t pay much attention to this advice and learned that design details is the magic which distinguishes great product design from mediocrity. All visually appealing designs share a few common traits. The number one most significant trait is simplicity. Industrial designers always try to unify many unrelated components, features, and parts into a single overall dominant form which expresses the product’s function. This can be a very challenging task, especially when a product is comprised of many parts and distinctly different components. The challenge lies in the creative expression of the product based on an overall shape which defines its function based on an appearance which brands the company’s identity. After an overall simple form has been created, it will remain somewhat boring because of its lack of details. A few great examples are flat screen TVs, cell phones, and computers. All these products are essentially flat rectangular forms. They would all be indistinguishable from one another without their specific details. The same holds true for the same product manufactured by different companies. Differentiating one flat screen TV from another is much more difficult than distinguishing one X-ray machine from another because the state of the art and number of parts. As products become simpler, your eye focuses on smaller details, which would typically go unnoticed in a more complicated assembly. Rotational molding is expanding into markets where appearance and quality are critical to a product’s market appeal. Since many of these products are expensive, consumers expect their purchase to be of high quality, highly reliable, and exceptional performance. The covers and overall structure must be molded with excellent surface finish, precision fits, and

These are examples of design details. Part quality is dependent on the designer as well as the mold maker, molder and resin supplier. All these stakeholders must work together as a unified team with a common vision. The designer is a critical participant in this process. He or she must motivate the team to attain the highest levels of design excellence without impacting production efficiency or increasing part cost. This requires a keen understanding of the process, tooling methods, and materials, which must be accommodated in all the design details. Examples might include specifying machined tools with an etched surface texture or the specific split line for parting the mold. Another might include the details for a joint between two parts based on reasonable clearances and required radii along edges. Although this brief editorial only scratched the surface of design details, I hope it made an impact on you. The next time you develop a product, you’ll hopefully realize all the time, cost and energy invested in design goes into part detailing. The concept is only 15-20% of the overall product development or success in the market. www.rotoworldmag.com 31

CP Cases, based in London, England is a vibrant, fast growing company that designs and manufactures high-performance protective cases for the storage and transport of high-value equipment for the media, entertainment and commercial industry. The company has over 45 years of experience in the design and production of cases and containers in plastics, welded aluminium, specialist rugged textiles and foam engineering. For the past 18 months CP Cases has been collaborating with the Polymer Processing Research Centre, School of Mechanical & Aerospace Engineering, Queen’s University, Belfast (QUB) as part of a 30-month UK Government (Innovate UK) sponsored Knowledge Transfer Partnership project, known as KTP. The project is specifically aimed at introducing and embedding the rotational moulding process into CP Cases production capabilities. The rapidly changing market demand has driven the project team to consider data acquisition in the early stages of planning. This article describes aspects of the project where the use of Virtual Reality (VR) techniques has been used to benefit and optimise the new rotomoulding factory set up, layout and design. Industry 4.0 and Virtual Reality Data acquisition, ubiquitous connectivity and real-time communication are changing how manufacturing companies function and operate. Is it a revolution or just the common-sense strategic deployment of new technology? There is now a growing understanding that elements of what we call “Industry 4.0” can be deployed at a relatively low cost and deliver immediate benefits. Industry 4.0 technologies and their increased use of digital and analytics are already improving manufacturing productivity, efficiency, and effectiveness. Digital advances and better human-machine interfaces are enhancing problem solving, operator training, and overall production performance. Lower automation costs are fundamentally changing discussions about when and how to use automation in manufacturing. There is growing consensus that the core concept, which hinges around the deployment of automation technologies and smart use of data, is critical to the future of manufacturing operations, large and small. Industrial production was transformed by steam power in the nineteenth century, electricity in the early twentieth century, and automation in the 1970s. Today, manufacturing is experiencing a fourth wave of technological advancement; the rise of new digital industrial technologies that are collectively known as Industry 4.0. Factory layout planning is a long-standing area in production engineering that sees great potentials of VR integration. It is 32 ROTOWORLD® OCTOBER-NOVEMBER 2020

getting wider attention in both research and practice as the virtual environment allows designers and planners to test out “what if ” scenarios with relative ease. Benefits of Factory Layout Planning One of the main benefits of building a 3D Model of a proposed new factory and using VR to visualize it is overcoming the distances between the project’s stakeholders. The richness and flexibility provided by a virtual model allows a ‘common view’ and better understanding for all of the planning team which improves and accelerates the decision-making processes. The decision making is also promoted by the ease of getting opinions and ideas from all levels of engineering and management by the simple platform that the VR layout provides. Another main benefit of Virtual Layout Planning is that it increases the amount of knowledge and understanding for cross functional teams at early stages of the project. 2D layouts could

sometimes be sufficient to evaluate some quantitative measures, such as footprint, travel distance and product flow. However, they are often only understood by ‘experts’. 3D representation on the other hand and virtual visualisation helped bridge the gap between areas of expertise. In addition to the quantitative measures, virtual layout plan allows assessing some qualitative measures prior to execution such as factory safety, ergonomics and operator preferences. In any design process, the designers have the largest freedom of choice at the very early stages whilst the cost of change is still negligible. However, the knowledge and experience the designer has is relatively low at this stage. Virtual planning boosts the level of knowledge at the planning stage (see Figure 1). Having a live and continuously updated CAD model, allows for running mini Six Sigma® and continuous improvement projects, and gives the chance to access its feasibility and efficiency prior to execution.

the machine. The ease of moving the machine in the virtual model is very efficient in determining the optimum position and gives the planning team a realistic appreciation of the actual size of equipment. It would be very costly and physically difficult to change the position of the machine after installation which is further discussed in the next section. The carrousel machine being considered had limited layout drawings. Therefore, it was very necessary to create models that could be easily integrated with the factory layout and viewed with VR to get a clearer appreciation of the actual footprint and size of the machine. Viewing the machine, positioned in the right place, together with utilities and ancillary equipment greatly assisted the planning and design teams, particularly Figure 2: Demonstration of the Use of VR with spotting some problems that have headset to navigate the Factory 3D Model a high chance of occurring and avoid them at an early stage. An example here was related is the positioning of the Gas meter and making sure it is in a safe and accessible position in case of emergency.

Other issues such as the obstruction of the pathway of the forklift and inaccessibility of the critical positions of the machine during maintenance, where also considered, evaluated and avoided at this early stage.

Financial Analysis Despite all the aforementioned benefits of using VR in factory layout planning, some still doubt the return on investment of using such a system, because the capital cost and modelling time required. The main reason for these doubts is that the estimated cost saving of making the change using VR during planning is always intangible. However, if we were to evaluate the feasibility of the system, we can evaluate repositioning of the machine as a case study.

project, the cost of the physical change and the expertise and knowledge of the planning team. Future Work When the project is successfully executed and the production starts at the new factory, the use of CAD and VR will still continue to support and optimize production; those activities would include: • Design of cooling jigs and frames and testing the operators’ ergonomics and preferences before manufacturing. • The mass properties of CAD software could be used to design self-balancing arms without the continuous need of manual arm balancing. Figure 6: Safe operating height virtual assessment

Figure 7: Raw material storage virtual assessment

Firstly, the virtual planning approach used requires a desktop and a SolidWorks license, both already present and available in the design department. In addition, an HTC Vive VR headset was purchased for this purpose at $650. This project required 4 months for planning, which included 4 weeks of modelling at a cost of $5000. Therefore, the total cost of the VR analysis was approximately $5650 (not including the computer hardware and CAD software). For every design change such as repositioning the machine, the team spent about half a day to discuss, model and evaluate the change. This resulted in an additional cost per iteration of approximately $300. If the repositioning was carried out after the machine installation and during the testing, that would require at least 1 working week of physical reconstruction, with a cost of at least $12,000, which is 40 times the cost of change during the early stages. If the repositioning was carried out after factory commissioning and start of production, that would add the cost of stopping production for 1 week, in addition to the cost of moving the machine, which would yield a total cost of $20,000, which is 65 times the cost of the virtual change. So, generally speaking, the financial gain of using VR in virtual layout planning is dependent on the complexity of the

Virtual Fall Meeting I am happy to report that ARM’s first virtual meeting is successfully behind us. As with any untested method, there’s a certain level of anxiety that comes with the territory, and this was no different. While the Forums and Programs Committee put together another excellent slate of presentations, the unknown of the unknown weighed heavily on our minds. Would people participate when balancing the meeting with their daily duties? Would the technology work as intended? The results from the meeting show that 98% of attendees reported that the meeting met or exceeded their expectations. Generally speaking, the technology worked, the presentations were on target, and members felt their time was spent in a beneficial way. We also heard that this format exposed more individuals to ARM than previous meetings since meeting attendance did not require travel expenses. This is all great feedback that will be taken into consideration for future meetings. Another result of moving our meeting online was that our virtual exhibit hall remains open at bit.ly/alltheroto There you can learn about more than 50 exhibitors and watch dozens of new videos from our suppliers, sharing the newest machines, materials, and more. 36 ROTOWORLD® OCTOBER-NOVEMBER 2020

While this format worked, we also understand that it is difficult, if not impossible to replace faceto-face meetings. Although our next planned faceto-face meeting is Rotoplas 2021, it remains a key objective to host a live meeting once it can be done safely and responsibly. North American Rotomolding Industry SWOT Analysis ARM conducted a SWOT analysis of the rotomolding industry for our online Annual Meeting. The goal was to get a baseline for the rotomolding process that rotomolders can use as they implement Industry 4.0 technology. This way we can compare where rotomolding is today with where the rest of the manufacturing world is going. We sent a freeform text survey asking for feedback. Many of our supplier members also work within other industries with manufacturers who use different plastic processes. Their critical feedback compares rotational molding with other processes. Strengths The strengths are in the eye of the beholder. Short runs, low cost tools, and creative parts are seen as the strengths of rotomolding but the folks on the shop floor don’t necessarily love them. Survey respondents noted the flexibility of the process, the shapes we can make, the ability for us to change colors, and the ease of tooling are all strengths. Many respondents also

ARM

REPORT mentioned low cost tools, which is definitely true in comparison to other plastic processes, and short runs. Durable parts are hugely important. There is a lot of talk about plastics being bad. The fact that our products are reusable, can be repurposed, and are durable goods, which puts us in a different category than other plastics processes. Other strengths include low capital needs for entry, and our capability of making very large parts. Some of our members are making incredibly large fluid holding tanks. So, what do our non-molder members say about us? They’re talking not as much about the process itself as they are the industry. Non-members commented on strengths such as the closeness of the industry, networking, and that it is the most cooperative industry to work in. We are unique in that rotomolders are very open and honest with each other. I think that really stems from the entrepreneurial feel that the industry still has. We are a lot of small, agile companies run by passionate business owners.

available, as an industry we choose to run primarily linear polyethylenes. Labor is one of the Achilles heels of the industry. We have a very manually driven process that requires almost a craftsman, more than a button pusher, to run our presses and perform secondary operations. Attracting labor, finding people who will work hard, and the general availability of labor, are all becoming more of an issue as we compete against people who are frankly automating their business and making the work easier. Our non-molder members talked about resistance to change, not embracing new resins, and focus on material cost rather than value. From talking to other molders and suppliers, and from being around the industry, I think this is accurate. There is a certain stubbornness associated with entrepreneurs and some molders out there are resisting change. This can be seen when you’re looking at materials and automation. There are more materials out there than linear polyethylene. However, based on cost and other factors,

In the recent Plastics News, where they list the top rotomolders from 2019, the top 20 molders make up about 50% of the market. The other 400 molders in North America make up the remaining 50% or about $3,500,000 of revenue per business. The entrepreneurial spirit also breeds creativity and fosters sharing. This industry feels a lot like craft beer, the other business that I’m involved with. One of the similarities is market reach. Because rotomolded products are large hollow parts they are difficult to ship very long distances, just like craft beer. That may be one thing that’s playing into this cooperative industry.

some people choose not to use them. There are also a lot of people choosing not to use automation, so I think there’s some pretty fair criticisms or ideas of what the weaknesses are within the industry.

Weaknesses One of the most common weaknesses mentioned is that we have a slow process with a higher cost. This really hits home. A number of years ago, a friend who used rotomolding as a very small part of their business summed up rotomolding as “cheap tools, expensive parts.” There are material limitations. We do have fewer materials to run than other plastics processes. While there are other materials

Opportunities Within a SWOT analysis, your strengths and your weaknesses are both internal looking. The opportunities and threats are viewed on a macro level. Some of the opportunities our members mentioned are conversions, automation, new materials, and customer market awareness. Conversions from metal, concrete, and wood are always discussed as we look for the next big product that is a takeaway from another industry. It gets us thinking creatively: what is the product and how are we going to make it? When we look at some of the weaknesses and threats, automation resolves many of those issues. As an industry, it’s a real opportunity for us to understand how we will make the most of automation. www.rotoworldmag.com 37

ARM

REPORT At our 2019 Annual Meeting, Toter shared a video of one of their automated machines, where there were 30 - 40 molds on a single machine. Both the molding and trimming operations were being run by a single operator. They accomplished this by leveraging automation. It’s interesting that our members labeled new materials as an opportunity because one of our weaknesses was material limitations. Our suppliers are telling us there are more materials that we are resistant to use. Determining what types of materials the market needs, and how to bring those to market will be very important in the future. Only a few respondents mentioned consumer market awareness, but it is a very interesting point. Our non-molder members commented that we need to educate the OEMs and designers on what we sell and the durability of our parts. I think these comments speak to expanding market awareness. Kayaks and coolers are the more popular consumer-facing markets for rotomolding. The premium cooler has done a really good job of promoting the process. Many manufacturers tout the process capability of rotational molding in making an almost indestructible product as why our process is superior to other processes. For an opportunity, how do we leverage that? We now have a group of consumers in the market who understand what rotational molding is and, more importantly, they understand the benefit that it has to create a robust product that they love using. We need to leverage that consumer awareness in the future. Though it wasn’t mentioned in our survey, I think our relatively small market size, coupled with the ingenuity and creativity of some of our entrepreneurs, could really lead to additional opportunities. Threats While there are a lot of external threats that are plaguing rotational molding, we are going to focus on those specific to our process. Obviously, we’re not going to mention things like pandemics because what are the odds of that actually happening? Lower cost and competitive processes were some of the most frequent results. We know there are other plastic processes out there that are becoming more competitive through automation. We’re seeing blow molders who can make larger and more intricate parts. The speed at which 3D printing is coming into the market and expanding is staggering. We’re also seeing competition with injection molding. The next biggest threat that was mentioned was labor availability and skill. As discussed, we are a very manual process and makes it difficult to find people to do the work that we need. When you do hire people, do they have the skills to be able to perform the work? How many rotomolders are hiring people who have never run a drill before? How many people don’t know the difference between certain tools? 38 ROTOWORLD® OCTOBER-NOVEMBER 2020

The last threat is environmental. For our industry, people always think of plastics being bad for the environment. You’re not seeing playground equipment and large stock tanks and things of that nature floating in the Pacific. We may not be a part of “Plastic Islands” but we do have microplastics. We do have our resins and our pellets that are washing out of our dumpsters and into the water stream. There’s absolutely an environmental impact we can have but when we talk about threats, one of the biggest environmental impacts we’re going to have is this emergence of electric engines versus combustion engines. We’re seeing more cars going electric. We’re seeing more components on machinery go from hydraulic to electric. There will probably always be a place for the combustion engine, but as electric motors become more powerful, as battery storage becomes less of an issue, I see this being a real threat to rotational molders, especially considering gasoline tanks, diesel tanks, diesel emission, fluid tanks, hydraulic reservoirs, overflow tanks. That’s a big part of our businesses. Our non-molder members had interesting feedback about threats to our industry related to rotomolders’ views on tolerances. One of the other really interesting comments made was by a supplier who talked about corporations and holding companies continuing to purchase rotational molding companies, and that the organizations are becoming less entrepreneurial and more corporate. The question or the opportunity we have with that is how do we keep larger corporations engaged? How do we keep larger companies coming to meetings and sharing information, and how can we do that in a way that doesn’t pose a threat to our members? What’s Next? I hope you’ll think about the feedback we received on the SWOT survey. What do you agree or disagree with? From your company standpoint, how do you compete? How do you match up against some of the stereotypes of rotomolding that came up? As you take a look at your internal direction for your business, what should you be doing more of, what should you be doing less of? What do you need to do to change the industry? How do you keep growing your businesses in terms of cost, quality, delivery, and ease of doing business? Its pretty clear what other industries are doing and I think there’s some legitimate opportunities and threats within our businesses that we need to take very seriously. In conclusion, I think there’s a lot of great things going on within the market. I think there’s a lot of room to improve. I think there’s a lot of opportunity on the horizon and it’s going to be very interesting in the upcoming years to see how people respond. Rick Carlsen ARM President

ARM

REPORT Technical Director Nick Henwood on Long-Term Material ARM recently held its Annual Meeting as a virtual event and this new format seemed to be a great success. Obviously, we all missed the normal human contact; the chance to meet contacts, former colleagues, and friends, in person. However, as a way of presenting information and opening up discussion, the on-line format certainly seemed to work. As part of the main event, we organized a technical session with presentations around a common theme, which was “Long-term Properties of Rotomolding Materials.” There was an introductory keynote, followed by four groups of expert speakers, plus a Q&A session. I would encourage any of you who missed out on this session to revisit it via the ARM website, where we now have recordings of all parts of the session available to all members. Some aspects of the same subject were also recently covered during our Design Webinar Series (Module 5), which is also available in recorded format. Does Long-Term Properties seem a subject which is rather esoteric and strictly for the “techies” amongst us? Possibly, but it really shouldn’t! There are several good reasons why any rotomolder should be aware of the basics of this subject, if not all the detail. As rotomolders, we’re invariably in the business of making durable products. Our customers expect that rotomolded parts will be made to last for years, if not many decades. Therefore, we need to be confident that our parts will meet service expectations over an extended period. Most rotomolded products are ultimately used in an outdoor environment, so the weatherability of the polymers we use and the stability of the colors we create are both very important. Whilst the choice of additives and pigment can generally provide adequate protection, we shouldn’t ever assume that this is a “given”. The most popular material used in roto is polyethylene (PE), a material that we all know and love. Whilst PE has many excellent properties, some of its long-term properties are less than optimal. As a semi-crystalline polymer, PE has relatively poor resistance to creep. When PE is subjected to load, it stretches, and this behavior is often described using tensile and flexural data. However, bear in mind that the usual tests stated on Data Sheets are only measuring these effects in the short-term. If the load is sustained for an extended period, PE continues to stretch; this is what is known as creep.

Another important issue, which is slowly gaining recognition in rotomolding, is crack propagation. Practical rotomolded parts will contain micro-defects (e.g. air bubbles and pigment clusters); under conditions of continuous or cyclic loading, these defects may act as sites for the growth of microcracks that can lead to sudden part failure after several years of use. Tests exist that will help us evaluate our materials by measuring long-term data. In principle, we should be able to build this into our Finite Element Analysis programs, or we can recommend Factors of Safety that should be applied. However, our industry does not yet have agreed testing protocols that have been proved to be reliable and robust in a rotomolding context. One of my missions, as ARM Technical Director, is to encourage and support the kind of research and development that will answer real problems and address practical issues. Fortunately, rotomolding has many talented and committed technical professionals that are willing to work together to help. This has always been a characteristic of our industry, as evidenced by the success of organizations such as ARM. “Knowledge is power,” so the first step is to raise awareness of the issues involved and their practical importance. Look out for future initiatives by ARM in this area and, if you haven’t already done so, I recommend that you make use of the existing educational resources that already exist. Happy rotomolding! Dr Nick Henwood serves as the Technical Director for the Association of Rotational Molders. He has more than 30 years of experience in rotomolding, specializing in the fields of materials development and process control. He operates as a consultant, researcher and educator through his own company, Rotomotive Limited, based in UK.

INDUSTRY 4.0

EPISODE 5

Rob Miller, Wittmann Battenfeld Canada Inc. / ROTOLOADTM

Perhaps it’s your Turn I have spent quite some time pondering the direction for the next few episodes. Not that there is any shortage of Industry 4.0 topics, ideas, principles… actually, quite significantly the opposite. If you ask 20 experts, you will for sure get at least 25 answers… I have had a number of interactions with other industry colleagues, discussing primary machinery, mold technology, downstream/post molding processes, considering where there might be opportunity to leverage Industry 4.0 to the greatest potential financial gain. One of the things that I did as I was planning was to go back and read through my previous episode submissions. As I did, it was quickly evident to me that each of the Industrial Revolutions made physical labor substantially easier. The primary purpose of each of the four major monumental shifts of thought seemed to have the main purpose of reducing or making more efficient the labor content of any manufacturing process. Therefore, in the end, I believe that the human aspect of our manufacturing has the greatest potential gain in efficiency from Industry 4.0 concepts. To be totally honest, I am not sure how many episodes it may take to fully examine some of these ideas and concepts, but I believe it to be very beneficial to work through some of this. I would like to start by taking a brief minute to introduce three common terms used in manufacturing, technology, economic, and business discussions, HUMAN, STRUCTURAL, and RELATIONSHIP Capital. HUMAN CAPITAL is your people. The description can go much deeper, to include your employee experience and knowledge, the relationship that the company has with those employees,

training policies and procedures, and employee satisfaction…do they enjoy their jobs and the company that they work for. STRUCTURAL CAPITAL relates to your legacy processes, policies, vision, and mission statement that all contribute to the culture of the organization. RELATIONAL CAPITAL is essentially as it sounds. It is the relationships that you share with your customers, suppliers, employees, investors, etc. The intent is to suggest that there is a point where these three factors within your organization intersect, and at that intersection is where you really experience the highest level of value. You may be asking…where is he going with this? Please stick with me, and I assure you that I will land the plane. (that is what my kid’s say anyways)

40 ROTOWORLD® OCTOBER-NOVEMBER 2020

There was an economist back in the late 1800’s, Mr. Alfred Marshall, and one of his quotes is the following. “The most valuable of all capital, is that which is invested in human beings”. Mr. Marshall was known for the original theory of Supply and Demand, as well as contributions to the theory of marginal productivity. Marginal Productivity essentially states that if you are paying an employee a certain wage, that your business revenue should increase by the same value, at the same rate, for the work produced by that same employee. Now, a lot has changed since the late 19th century, and some of these prominent theories of the time don’t really apply any longer, or at least are disputed. As I explored this topic, I was left to wonder if each of our employees actually add their hourly wage in comparable value to our bottom line?

INDUSTRY 4.0

EPISODE 5 Fast forward a hundred years or so, and we find another economist, Mr. Thomas A. Stewart. One of the quotes that I found quite interesting when applied to these theories was “Human capital grows two ways: When an organization uses more of what people know, and when more people know more stuff that is useful to the organization.” I will begin to lower my landing gear now… I think one of the most common statements that I have ever heard in this ROTO industry, is that every facility that I have ever visited or discussed could use more people. If this lack of available labor is one of the most common barriers to our meet our production needs, and even more important, our true potential capacity, then why are we not leveraging our RELATIONSHIP CAPITAL, along with our HUMAN CAPITAL, to build the STRUCTURAL CAPITAL of our organizations. Final approach… Our people often already know what can be done to make the process easier, more cost efficient, less labor intensive, safer, better, and in every way, improving the bottom line! If there is a manual labor process in our facility, it can be almost guaranteed that our team (Relationship Capital) can help us make it more efficient. This definitely includes some of our trusted employees, but also extends beyond to find valuable supplier relationships, and to open up communication with our customers to get a feeling for what they would see as beneficial, but also what they may be willing to pay for. Not that we should be asking our customers to pay for our automation, however, there are perhaps benefits that they may see an advantage from, and therefore, continue to be a valuable contributing partner. This is where the Industry 4.0 principles begin to take shape.

As I have commented several times, Industry 4.0 is all about the data. If we can leverage our STRUCTURAL, HUMAN, and RELATIONSHIP capital, and use simple technologies to inexpensively collect DATA that will help us and our teams make productive, efficient, and quality improving decisions about our processes, why would we not want to move forward in these initiatives? If we go back a few paragraphs, we can look at this from the “marginal productivity” perspective, but more related to the technology investment, rather than the hourly wage. Any investment in technology should have a return on investment strategy that allows each aspect of your labor profile to generate significantly more than your project, or hourly investment. So… I have realized that I am one thousand words into this episode, and not discussed any specifics. The more that I thought, wanted to explain and write, it was clear to me that we need to start on a common thought process before we get into any specific realworld applications and how to solve them. I have some thoughts of my own, but I

would really like to do an experiment. In this new reality of travel challenges, we don’t have the ability to meet face to face, and to tour your facilities to discuss these important topics. I would really appreciate the challenge of looking deeper into your questions, issues, and problems, to leverage the RELATIONSHIP CAPITAL that I have developed. That way, I can work with your challenges to sketch out high level outlines, and present detailed propositions as to how Industry 4.0 can solve and improve your labor challenges. Would you be willing to please consider writing to me by email at rob.miller@ wittmann-group.ca. The source of all questions/comments will be kept expressly confidential, unless otherwise given permission. That way, it won’t be my thoughts, ideas, and solutions, but those that are generated by you and important to you, the innovative, experienced and sometimes challenged molders that are experiencing labor related issues on a daily basis. Thanks in advance for your participation, and I look forward to hearing from you soon! Until next issue, please stay healthy! www.rotoworldmag.com 41

What Rotomolders Need to Know about Polymer Chemistry – Part 1 “How Comonomer Type Influences Polymer Properties” Dr. Nick Henwood, Rotomotive Limited

Rotomolders tend to be more mechanically minded than chemically minded and typically they do not have a deep understanding of polymer chemistry. Fortunately, the technical experts within polymer supply companies can often help with material selection decisions and resolve performance issues. While this approach usually works from a practical standpoint, “knowledge is power” and molders will benefit from sufficient understanding of polymer chemistry to make the right choices, especially when they are receiving conflicting advice from different suppliers! The Association of Rotational Molders (ARM) frequently receives queries from members who are trying to navigate their way through a maze of information to make the right choices. As ARM’s Technical Director, most of these queries land on my desk. I always try to provide the most direct and straightforward answers that I can, but often a little background information is required to explain my comments and recommendations. In this series of articles, I will seek to provide useful insight without getting readers too immersed in unnecessary detail, concentrating on some of the more common questions that I get asked. One such question relates to the function and effect of comonomers in different polyethylene (PE) grades. Most often this comes down to questions like “what’s the difference between a rotomolding resin made from butene versus one made from hexene?” Butene and hexene (strictly speaking: butene-1 and hexene-1) are examples of comonomers that are used during the production of different PE grades, including roto grades. They do essentially the same thing for PE, but their presence can cause some differences in grade performance. PE is a semicrystalline material; in its solid state, the molecules contained in PE may exist in one of three different configurations. • Some molecules will be folded up in regular structures; these are in the crystalline phase. • Some molecules will not be folded up and are present in a more irregular arrangement; these are in the amorphous phase. • A few molecules may stretch between different crystalline regions, with their ends embedded into two different regions; these are called tie molecules (see Figure 1). The proportion of crystalline versus amorphous phases will have a big effect on PE characteristics. High crystallinity grades are stiff and relatively brittle, while low crystallinity 42 ROTOWORLD® OCTOBER-NOVEMBER 2020

Figure 1: Tie Molecules

grades are more flexible and resistant to impact. In simplistic terms, the crystalline phase is what gives PE its stiffness and the amorphous phase is what gives PE its toughness. Selecting an appropriate grade for an application will involve finding a balance between stiffness and toughness needs. Crystalline PE is denser than amorphous PE, so measuring the density of the overall material will provide a good indication of the relative proportions of crystalline and amorphous phases. Roto grades in the density region 0.935-0.945 g/cm3 represent a roughly equal balance between crystalline and amorphous phases; they are reasonably stiff and reasonably tough. Injection molding PE grades have a significantly higher density (>0.950 g/cm3) and are stiffer, but generally more brittle. Cast and blown film grade PE’s mostly have a lower density (<0.925 g/cm3) and are less stiff (i.e. more flexible) and significantly more tough. A word of caution should be struck regarding terminology. The most technically accurate term for roto grade PE would be “linear medium density polyethylene” (LMDPE). However, custom and usage in different geographic areas of the world has resulted in some confusion in terms. For example, in North America, roto grade PE is often referred to as “linear low density polyethylene” (LLDPE) or as “high density polyethylene” (HDPE). While this confusion is unhelpful, we have to acknowledge that it exists! During the manufacture of PE, comonomers are introduced into polyethylene reactors to reduce and control the density of the PE grade being made. With no comonomer, the reactor product will be so-called “homopolymer” HDPE: a very stiff material with a density >0.963 g/cm3. This product cannot be easily rotomolded, but it can be used for other polymer processes, such as injection molding. Comonomers control the balance between the crystalline and amorphous phases in a PE grade. The more comonomer that is incorporated in the PE, the lower its density will be. The

comonomer molecules work by forming branches on the main PE backbone chains. These branches partially prevent the PE chains from folding into regular structures, which lowers the crystallinity, as well as the density of the PE produced. The inferiority or superiority (depending on which property is being considered) of PE grades made with different comonomers is the subject of considerable discussion amongst the various technical authorities in rotomolding. My personal viewpoint has been established by my own tests and work carried out in a variety of different geographical areas, where practice can vary. This has been quite instructive. In the European roto market for example, rotomolding PE grades are offered that utilize all three common comonomer types: Butene-1

4 Carbon atoms present in the comonomer

Hexene-1

6 Carbon atoms present in the comonomer

Octene-1

8 Carbon atoms present in the comonomer

there are many rotomolded products made successfully with butene-based grades. However, this also depends on other factors. The main area where we may see differences between similar Melt Index (MI)/density combinations is related to the long-term properties of PE grades. The normal measure we use for long-term properties is Environmental Stress Crack Resistance (ESCR) and here we do see differences in performance between grades made with different comonomers. The most common ESCR test method used for roto grades of PE is ASTM D1693. Sample coupons are notched (to provide a point of stress concentration), bent almost double (to provide a constant sample strain) and immersed in a stress-cracking agent at an elevated temperature (to significantly accelerate sample failure). Sample coupons are monitored, and the time taken for them to fail is expressed in hours. Figure 2 shows samples that have “passed” and “failed”. As a test, the standard ASTM ESCR evaluation method has its faults, the main one being that it can only provide a rough differentiation between grades. It offers relatively low precision,

In contrast, most of the PE roto grades offered in North America utilize hexene-1. Similarly, roto markets in Australasia and South Africa predominantly use hexene-1 grades, because their local suppliers have chosen to utilize this particular comonomer in their production of PE generally. Markets in South Asia, India and China tend to use butene-1 grades; once again, the practice of local suppliers sets the tone. Given this geographic diversity, what are the real differences between PE grades made from different comonomers? It should be stressed that the comments and conclusions in this article relate specifically to the PE grades used for rotomolding. The assessment would be different Figure 2: Passed/Failed ESCR Samples if we were looking at extruded and cast film applications (which mainly use much lower density PE grades) or injection molding but it does enable grades to be classified into long-term property applications (which mainly use much higher density PE grades). groupings such as “poor”, “good” or “excellent”. PE roto grades Comonomer choice is likely to make much more of a difference with a MI of 5 g/10mins and above will generally have “poor” with lower density PE grades, simply because so much more of ESCR, whatever the comonomer choice. This is because the MI it is needed to achieve the required density (normally at <0.925 has a greater effect on ESCR than any other factor. PE grades g/cm3). With the higher density PE grades used, for example, in with a lower MI (2 – 4 g/10mins) will have “good” to “excellent” injection molding (0.950-0.965 g/cm3), there will be a smaller ESCR properties and this is the area where there are measurable levels of comonomer, or even zero comonomer. differences due to comonomer choice. For roto grade PEs in this Rotomolding grades are mostly in the range 0.935 – 0.945 g/ MI range, hexene-1 grades tend to exhibit higher ESCR values cm3. Therefore, the choice of comonomer is likely to have a more than butene-1 grades. The further benefit of octene-1 compared limited effect on properties. This is what is generally observed; to hexene-1 is harder to observe in the roto grade range. www.rotoworldmag.com 43

Thai Government Hatchery Utilizes Rotomolded Parts to increase populations of the Blue Crab Oceanâ&#x20AC;&#x2122;s natural resources have been dramatically depleted in recent decades due to over-fishing and indiscriminate catches. This causes a disruption in the natural life cycle of marine animals and leads to reduced marine life population. Without some type of human intervention, it is unlikely that nature can heal itself back to the same sustainable level. In this issue, we will discuss a case study about a government hatchery center that utilizes rotomolded tanks and bins to increase the population of ocean blue crabs. This hatchery is located in Chantaburi, a coastal province in eastern seaboard of Thailand. It was found about 23 years ago by the vision of late King Rama 9.

Blue crab populations in the Gulf of Thailand have drastically decreased over the years. Blue crab is a local marine life commonly found worldwide. It is quite a popular delicacy both in homes and restaurants. There is also a large commercial fishing of blue crabs for its meat to be processed as frozen seafoods. As a result, blue crab populations in the Gulf of Thailand have drastically decreased over the years. In the natural environment, blue crabs take about 4-5 months to grow and mature into adults. One mother crab can produce about 300,000-700,000 eggs but less than one percent (or 3,000 crabs) will survive and grow into adulthood. In the past,

SPEAKING local fishermen would keep all the crabs (including pregnant crabs with external eggs) they could catch even though these mature eggs are not edible. As a result, blue crabs never had a chance to reproduce and replenish the ocean— causing huge reduction in blue crabs population in the Gulf of Thailand. Sea Farming Demonstration Unit in Kungkrabaen Bay in cooperation with a Pack Foods Public Co. Ltd. started a program called “Crab Eggs Loan” to borrow pregnant crabs from local catches, harvest their eggs, and return these crabs to the fishermen. Collecting these eggs is done by hand by using nylon brushes to gently scrub the bottom-side of pregnant crabs with external eggs, which can vary from orange to dark brown. Orange color indicates that the eggs are still young and will take a few days to hatch while dark brown mean these eggs can catch within hours. These harvested eggs are entered into Circulation and Separation Hatching Technique (CASHT), which consists of seven (7) blowmolded HDPE 150liter tanks connected in series, a water circulating pump, and oxygen pump. At the end of the line, there is a rotomolded cone-shape bottom hopper, where separation of crab eggs and baby crabs take place. Air is added into the tank to cause baby crabs to rise to the top and crab eggs to sink to the bottom. Crab eggs are suctioned back to Tank Number 1 and recirculated continuously until they hatch. Baby crabs, which float to top, will overflow to an open-mouth rotomolded rectangular bin, where they are caught in a receiving net. Remaining water is also circulated back to the system. These tiny crabs are then collected to be released into open water at night between 9 p.m. and 3 a.m. for highest chance of survival. The rotomolded separation unit was manufactured by Ocean Plastics Co. Ltd. (Thailand) with general-purpose grade medium-density polyethylene (0.932 density and MI 4.0). Originally, it was designed to be a beer dispenser.

SPEAKING Since the program has started, there is a noticeable rise in blue crab population in the Kungkrabaen Bay and nearby coastline. This indicates that the program has a positive impact in restoring local marine life as well as livelihoods of fishermen in the area. As a result, there is an easy cooperation from both local fishermen and surrounding communities to voluntarily donate pregnant crabs to the program. Since September 2012 until August 2020, it is estimated that the Center has processed 431,000 pregnant crabs, whose eggs of about 9.8 metric tons have been collected and released back to the nature. In summary, simple rotomolded tanks and bins with the right design and accessories can be great affordable tools to restore the well-being of both marine life and local fishing community.

ROTOCONNECT

Final Report from Graeme Hall The Outgoing President of ARMA RotoConnect I am honoured to include my final report as President. The production of this report is a key requirement of a not for profit industry association, so we hope you find it informative and can garner great insight into ARMA RotoConnect and its activities over the last 12 months. A short reminder of what we are about. ARMA is the premier organisation for rotational moulders and suppliers throughout New Zealand, Asia, and Australia. ARMA RotoConnect offers opportunities to engage directly with change makers all around the world within the rotational moulding industry. RotoConnect is our global brand that offers limited membership/support and is open to moulders around the world outside of Australasia. It provides key benefits that can assist your business globally. I am sure it has been the case for many, that most of 2020 has been significantly impacted by the COVID-19 pandemic. Irrespective of political and social views on how the management of this worldwide pandemic has developed, it has had a significant impact on ARMA’s operations and the broader rotational moulding industry. The postponement of our annual conference, Rototour, and Master Classes have affected the operation of the association. To continue to provide the high level of support we all currently enjoy, we need ongoing revenue. As most of you are aware this comes predominately from two places - subscriptions and events. With events suspended this has impacted ARMA RotoConnect as it has many associations around the world. The ARMA RotoConnect team has done an amazing job in mitigating the financial impact and have managed to maintain a high level of service. Demonstrating considerable fiscal responsibility, professional standards, and personal sacrifice. Ongoing support of our members has been the constant in a rapidly changing world. Although we were not able to get together in Hobart as planned, the team managed to put together the first Rotomould online event that was hugely successful. Our thanks go out to Michelle Rose for leading the event and assembling the content and ultimately managing a very engaging program. 48 ROTOWORLD® OCTOBER-NOVEMBER 2020

In amongst the turmoil of 2020, ARMA RotoConnect has managed to see the completion of a comprehensive review of the tank standard ASNZS4766:2006. ARMA was the champion of the revision, facilitating the inclusion of chemical tanks and buried tanks and can be very proud of the publication of ASNZS4766:2020. There is a massive amount of work gone into this updated standard and we thank everyone for their effort, experience, and the knowledge that they contributed to this great outcome. I know the energy Leisa put into the entire exercise and it was an amazing achievement. Encapsulating industry needs and translating a vast array of data. For the industry experts that contributed so much time, we cannot thank you enough. ARMA RotoConnect has sometimes been accused of being a little water tank focused. Which is understandable when you consider the number of tank moulders and the volume of material that is generated through this industry sector. However, I want you to consider the broader benefit that the tank standard brings to the wider rotational moulding industry. The testing of materials, analysis of design, and process controls provide a significant foundation for the broader non-tank rotational moulders. It generally lifts the requirements and capability of the wider industry. As moulders and suppliers, you should be using some if not all of the standard in your business. In the final months of my presidency I can reflect on the wonderful support of the board of directors and I offer my personal thanks for their selfless contribution and effort. I’m very proud to be given the opportunity to sit as chair of the association and although it has been a strange year, I’m sure the association is well placed to continue into the future with the ongoing efforts of the ARMA RotoConnect team and board of directors. During this financial year we also have two of our board members stepping away. Lester Ferry and David Garland who have been very good contributors and thoughtful and considerate members of the ARMA RotoConnect Board of Directors. On behalf of the board, staff, and members I wish to pass on our thanks for their contribution. As a not for profit they have freely given their time and it is greatly appreciated. David has worked

ARMA RotoConnect CEO’s Report for 2020 It almost seems necessary to divide this year’s report into two separate sections. As with most of our lives, 2020 seems a different century to 2019. In 2019 ARMA RotoConnect held a very successful face-to-face conference, an amazing Rototour, and finally another excellent Masterclass and we were kicking the goals our members expect of us. Work on the standard took the majority of my professional time right up until March 2020 when the final draft was submitted along with work on the Flame Retardant & Ultrasonic Cure Tests and in March I was lucky enough to spend time in South and Central America preparing for Rototour 2020. Like the rest of the world, our industry has been impacted by Covid, however unlike so many other sectors many of our members are thriving and all are surviving at the time of writing this. Of course, it is impossible to predict the outcome of this year however it is reassuring to know that for our moulders and suppliers, business has been able to continue. For ARMA RotoConnect itself, things have proven just a bit more challenging. As we have progressed through the middle months of 2020 it has become obvious that the Board has needed to use strong judgement and critical thinking to ensure a stable future for the industry body.

Previous Boards’ work in establishing and securing a buffer of operational funds has been instrumental in allowing time to consider the full impact of COVID-19. Without that investment we would have joined the many other industry and non-profit bodies that have had difficulty maintaining their staff and services. Careful consideration and budgeting, as well as some innovative thinking and support from the staff at all levels will ensure that ARMA RotoConnect does continue to provide a network for industry, an overseeing eye for training development, the establishment or representation on various industry standards, and leadership for the sector in sourcing new markets and managing our product life cycle. It’s a very big job for a very small team and we look now to our industry to continue to support ARMA RotoConnect through 2021 while we reinvent many of our usual face to face activities and we think you’ll be delighted and surprised by some of the results. The whole team at ARMA is passionately engaged in providing whatever our members need to succeed and we all thoroughly enjoy sharing both your challenges and your successes.

ARMA

ROTOCONNECT ARMA Working Groups 2019 was the start of several ARMA working groups working on topics and projects that impact the rotational moulding industry and most groups were implementing tasks right into the second quarter of the year. From that time, our members needed to focus more on their own business, so while the groups are on hold, it will be full steam ahead when possible. Environment Group: This group is one of the most active with real solutions already developed to assist the industry when it comes to the environment. The Environment Group was established to focus on differentiating our industry from the single use plastics that have constant negative media surrounding it. From this first initiative came the ARMA Recycling Logo which was launched earlier in the year and is already on websites and products within the membership and growing each day. The next initiative was partnering with Operation Clean Sweep to promote zero pellet and powder loss within the industry. This can be by way of self-audits although New Zealand members

are able to access paid audits through Plastics New Zealand and ARMA RotoConnect will offer this service to Australian members in the future. Integrity Group: This group is a quiet achiever that responds to industry complaints of all kinds and have spent time this year putting together better and stronger guidance for moulders on what they should and shouldnâ&#x20AC;&#x2122;t say to sell their products, how they should deal with warranty issues and how to clearly define their standards compliance claims; Research & Technical Committee: This work to identify possible solutions in flame retardant materials that will allow the industry to access new markets continues. The test nondestructive postproduction tests which look through the walls of products with ultrasound is almost complete with outstanding results. Finally, the group will be providing guidance for our new PhD Student working at Queens University in Belfast in a joint project between ARMA & ARM-Central Europe.

ARMA RotoConnect 2021 & Beyond

At the end of 2019 we were extremely busy with the development of subcommittees and the finalisation of the tank standard and as we headed into 2020, an exceptionally busy year was ahead. And then everything changed. While our ongoing projects are still going ahead, with the finalisation of the tank standard and the QUB research project still moving ahead, it has been at a 50 ROTOWORLDÂŽ OCTOBER-NOVEMBER 2020

slower pace than normal with closures around the world. With the loss of major events, it has changed how the staff of ARMA RotoConnect work and what they work on but we have a positive outlook for 2021, with the advancement of hybrid events a way of the future and we hope to be able to meet with our industry friends in the near future!

NEWS BRITISH PLASTICS FEDERATION ROTATIONAL MOULDING GROUP • BPF

BPF Highlights the Plastic Industry’s Impressive Response to COVID-19 The British Plastics Federation (BPF) has released a document highlighting the important contribution of the plastics industry in the fight against COVID-19 through the manufacture of PPE and critical infrastructure materials. Over the past year, the BPF has helped many organisations, including the UK government, Scottish Government, and Welsh Government to source vital supplies of PPE for frontline healthcare workers.

International Trade (DIT) and the Department of Health and Social Care, and has held regular meetings with the Department for Business, Energy, and Industrial Strategy (BEIS) to share key information. BPF members around the country have provided hospitals with plastic parts for ventilators, clinical waste sacks, aprons, face shields, visors, and millions of bottles for muchneeded hand sanitiser.

The BPF has also assisted a number of UK government departments, including the Cabinet Office, the Department for

The trade association’s visual document highlights key facts about the role of the plastics industry in the fight against

HOW THE PLASTICS INDUSTRY RESPONDED TO COVID-19 Prior to COVID-19, less than 1% of PPE was manufactured in the UK but by December 2020 domestic supply is anticipated to meet 70% of forecasted demand in England for all categories of PPE.*

British Plastics Federation

HAND SANITISER BOTTLES

EMERGENCY INFRASTRUCTURE

Typically made from PET. During the height of COVID-19, plastics companies were called upon to deliver over 50,000 bottles of hand sanitiser per week to the NHS. Over 20 BPF members are able to manufacture hand sanitiser bottles. Hand sanitiser bottles can be put in your recycling bin.

Everything from a testing site to a Nightingale hospital requires a steady supply of plastic, including road barriers and construction products like flooring, insulation, pipes, windows and roofing.

APRONS

FACE VISORS

100+ companies in the UK produce the sheet itself, which is often LDPE or LLDPE. There are now at least four UK apron manufacturers. These companies repurposed their factories in response to COVID-19. BPF research shows that the UK has capacity to manufacture more than 100 million aprons per month.

Typically made from PETG or PC. Over 30 UK companies manufacture the plastic screen itself, with a smaller number who construct the visors. UK plastics companies have the capacity to deliver over 3 million visors per week to the NHS.

CLINICAL WASTE SACKS

FACE MASKS

Heavy duty sacks that are able to seal clinical waste safely are vital in times of emergency. Demand for these sacks has increased 170% since the start of COVID-19.

There are multiple grades of facemasks, with FFP3 providing the most protection. A highly specialised ‘melt-blown’ fabric material is used for many masks. Just one company in the UK makes FFP3 masks, with production beginning in mid-2020 in response to COVID-19.

PLASTIC SCREENS VENTILATORS

These are mainly acrylic and have been used in shops and businesses around the UK. Over 20 BPF members can supply the sheet material, with several who manufacturer the final screens.

*Excluding gloves

54 ROTOWORLD® OCTOBER-NOVEMBER 2020

Plastic is used in ventilators and other medical devices because it is biologically inert, lightweight and strong. Hospitals had 7400 ventilators at the start of the , lockdown and now have more than 30,000. UK plastic companies have been supplying parts, including tuning knobs and breathing tubing.

COVID-19, which will also be disseminated widely on social media where the organisation has a strong presence. These include: • During the height of COVID-19, plastics companies were called upon to deliver over 50,000 bottles of hand sanitiser per week to the NHS. • UK plastics companies have the capacity to deliver over three million visors per week to the NHS. • BPF research shows that the UK has capacity to manufacture more than 100 million aprons per month. • Demand for clinical waste sacks has increased 170% since the start of COVID-19. • Everything from a testing site to a Nightingale hospital requires a steady supply of plastic, including road barriers and construction products like flooring, insulation, pipes, windows, and roofing. • Prior to COVID-19, less than 1% of PPE was manufactured in the UK but by December 2020 domestic supply is anticipated to meet 70% of forecasted demand in England for all categories of PPE except gloves, according to government research. BPF members have been integral to this achievement and the trade association produced online resources during the height of the pandemic, which aggregated key information for the industry to help businesses run effectively and safely, as well as a hosted an online ‘find a supplier’ service for companies and organisations in need of vital supplies.

Members of the BPF were also recently praised for their work in response to the pandemic by the Parliamentary Under Secretary of State at BEIS Nadhim Zahawi at the trade association’s ‘virtual’ Annual Dinner in October. Director General of the BPF Philip Law states: “Since the start of the COVID-19 pandemic, the BPF and its members have helped to meet the challenges faced by the NHS and industries across the country as they try to provide a safe environment for their staff, patients, or customers. Many BPF members have transformed and expanded their manufacturing operations, working longer and harder to ensure we can provide the protective equipment and medical supplies the UK needs. Over 100 of our members now manufacture PPE or the materials that supply PPE and we will continue to play our part in the fight against COVID-19.” ‘How the Plastics Industry Responded to COVID-19’ will be disseminated to BPF members and is available to download to help the industry communicate its achievements to key decision makers, customers, the public and staff.
