FROM THE

PUBLISHER Susan Gibson, JSJ Productions, Inc.

Statistics Predict Growth for the Plastics Industry Statista is an online portal providing data on the global digital economy, industrial sectors, consumer markets, public opinion, media, demography, and macroeconomic trends. It uses quantitative data from 425 economic sectors in 50 countries with a range of infographic tools for analysis and visualization. In recent studies, statistics and facts, Statista reported, “The plastics industry as a whole has produced more than nine billion metric tons of plastic materials worldwide. Plastics have become a ubiquitous part of human life. The Global Plastics Market was valued at 580 billion U.S. dollars in 2020 and is expected to experience considerable growth over the next decade.” The report indicated the annual global plastic production reached a high of 368 million metric tons in 2019, having experienced a compound annual growth rate (CAGR) roughly 3. 5 percent from 2010. However, the plastics industry was disrupted in 2020 due the COVID-19 pandemic, which caused outputs to decrease by an estimated .3 percent compared to 2019. It also cited China as the leading producer of plastics, accounting for roughly 31 percent of global production, with North America as the second largest producer with plastic production the United States amounting to more than 56 million metric tons in 2019. While there are thousands of different plastics, there are approximately seven broader types of plastic produced and consumed in large quantities: polyethylene (PET); high-density polyethylene (HDPE), polyvinyl chloride (PVC), low-density polyethylene (LDPE), polypropylene (PP), polystyrene/styrofoam (PS), and other miscellaneous plastics. Polyethylene (PE) is the most widely produced plastic worldwide and is used to produce many products including those that are rotomolded. The second-most produced plastic is polypropylene (PP), of which more than 70 million metric tons produced in 2020. Despite the recent backlash against plastics due to pollution concerns, mostly due to PET bottles, plastic remains a hugely important commodity that is used in virtually all aspects of modern daily life. Thus, plastic demand is set to continue growing for the foreseeable future, with production set to reach 589 million metric tons in 2050. Recently, Plastics News reported in their important annual rotational molding ranking that average sales per company was up 10 percent over 2019, and combined sales of more than $2.6 billion for 2020. 107 firms made this year’s ranking, which was up 3.5 percent

over 2019. Proprietary molding takes the largest share with $1.5 billion (60%); custom molding comes in at $605 million; and captive at $128 million. Plastics News reported consolidations within the industry accounted for fewer firms being ranked in this year’s report. Tank Holding Corp has acquired Duracast Products, Inc., Rotational Molding Inc., Rotational Molding Utah, and Spin Products Inc. Myers Industries, Inc. has acquired Ameri-Kart Corp, Elkhart Plastics Inc., and Trilogy Plastics. Sterling Rotomolding, and Vista Plastic Solutions Inc. each acquired some assets from Acrylon Plastics Inc. However, two new companies were added to the rotational molding ranking this year including: Agri-Plastics Custom Rotomolding of Nebraska and Vista Plastic Solutions of Manitoba. The movers and shakers for the year included: Simplay3 Co.; Stern Assembly Inc., dba Stern Rotomoulding; Jer-Den Plastics Inc.; Entegris Inc.; Rotoplast Inc.; CPI Products; Faribo Manufacturing Co.; Ken Ross Inc.; Horsemen’s Pride Inc.; and California Rotational Plastics Inc. Be sure to check out the ranking in the August 23 print edition of Plastics News and see their website for the full listings. www. plasticsnews.com/rankings/rotomolders. We are pleased to bring you some great reading in Issue 4 for 2021. Ian Hansen, well-known industry consultant, writes about a new rotomolded Cloud Seat that combines the European spirit of simplicity with the elegance of the East in a new product for outside spaces. Alvin Spence writes a remarkable update on changes within the industry over the past two years as COVID-19 placed its hold of virtually every part of the world. Ian Hansen also provides an informative look at what to be aware of when designing a chemical tank fit for purpose. I want to mention that Contributing Editor Martin Coles is providing a series of excellent information regarding the issue of reducing gas dependency (see page 30). Rob Miller is continuing to address industry members’ questions regarding Industry 4.0 (see page 54). Be sure to keep up with these important columns for up-to-date information valuable to your company’s future. Looking forward to seeing you at Rotoplas!

Polyethylene (PE) is the most widely produced plastic worldwide and is used to produce many products including those that are rotomolded.

UPFRONT Redline Plastics Announces Expansion MANITOWOC, WI, USA —

Redline Plastics announces a 103,000 sq. ft. expansion to their manufacturing facility in Manitowoc, WI. This expansion will more than double the production space of their current facility, completed in December 2019. The company has broken ground on the expansion and anticipates the facility will be complete around August of this year. The additional space is needed due to rapid growth in their rotational molding and vacuum forming businesses. When Redline opened their 117,5000 sq. ft. manufacturing facility in December 2019, the company employed 75 people. The company now employs 145 with about 25 current job openings and more to come as the expansion is completed. “Redline’s incremental growth over the past several years has been nothing

short amazing. This is due to the great team and culture we have been able to form here at Redline,” said Nick Murray, Vice-President of Operations. “We had this expansion planned since the first half of the building started construction in 2019, but we did not anticipate expanding for at least a couple of years. We are lucky to be in the position we are in and continue our investment in the area, our employees, and our customers. Without all of them, our success would be limited. Future employment levels are hard to estimate, but if our growth and ability to deliver quality products on time continues, we can more than double our workforce over the next several years.” The expansion is an investment of over $6 million into the building and capital equipment.

UPFRONT Queen’s University Belfast Launches its New Advanced Rotational Moulding Automation Cell (ARMAC) The Polymer Processing Research Centre (PPRC) at Queen’s University Belfast has recently installed an Advanced Rotational Moulding Automation Cell (ARMAC) supported by its technology partner AMS Belgium BV. (www.ams-innovation. com/). The total investment in the cell and its cutting-edge technology is in the region of €500,000. ARMAC will help improve rotational moulding process efficiency, quality, and speed by utilising the latest state-of-the-art electrically heated autonomous RobomouldingTM machine. The system is up to 50% more efficient in terms of energy use compared with conventional machinery, and is the only one of its kind in the UK & Ireland. The new cell is composed of two advanced industrial robots. The larger Robomoulding machine has the capability to manufacture complex, multi-layer foam and fibre-reinforced parts, which is supporting the work of a team of 5 researchers at QUB under 2 EU funded research programmes: CITI-GENS and Renewable Engine (www.renewableengine.co.uk/). These are aimed at improving the efficiency of the rotational moulding process by targeting areas such as: (a) powder distribution simulation; (b) ultrasonic monitoring of material layup within the mould; (c) real-time sintering and densification behaviour of the polymer during moulding; and (d) automated internal mould cooling. A further PhD researcher, sponsored by ARMA (ARMCE & ARMA) is using a second smaller robot in the cell together with a vision system for part location and placement. This project

is also designing specialised end effectors to enable the robot arm to conduct pre and post moulding inspection / operations and provide crucial quality control feedback. The technology behind the two robots is unique, representing the state-of-the-art for rotational moulding technology and ARMAC will be an invaluable resource for the industry worldwide. Some of the latest research that has already begun to exploit ARMAC is in: (1) the development of multi-layer hydrogen gas liners for commercial transport / storage solutions; and (2) the testing of advanced digital manufacturing technologies for the rotational moulding process.

E.U. Recommends Travel Ban for American Tourists

Iceland

Switzerland United States

Spain Greece Jordan

Mexico

Dubai (United Arab Emirates)

Seychelles

As expected, the European Union recommended, as of August 30, that its 27 member nations reinstate travel restrictions for American tourists because of rising coronavirus infections in the United States. The European Council has decided to remove the U.S. from its ‘safe list’ of countries for nonessential travel. This is a reversal from its June decision to recommend lifting restrictions on American travelers just as the summer tourism season kicked off. However, this guidance is non-binding, so individual countries in the E.U. bloc can decide to impose their own sets of restrictions. Travelers should expect a messy patchwork of different rules and regulations across the continent, much like they encounter a mishmash of non-uniform rules and regulations across the U.S. Despite the E.U.’s recommendation, some countries in the bloc will likely continue to allow fully vaccinated Americans to visit as long as they show proof of their vaccination status. Unvaccinated U.S. travelers will likely be faced with rigorous restrictions including frequent testing and quarantines upon entry, if they are allowed to enter at all. Five other countries were also removed from the E.U.’s safe travel list today: Israel, Kosovo, Lebanon, Montenegro, and North Macedonia. The United States never reopened its own borders to E.U. tourists during the pandemic, a point of contention among many Europeans. The new recommendation, they say, reflects a certain reciprocity. The threshold for being on the E.U. safe travel list is having fewer than 75 new Covid-19 cases daily per 100,000

The Delta variant of the coronavirus has ravaged the United States all summer, leading to spikes in hospitalizations and deaths rivaling where the country was in December and January. According to the Brown School of Public Health’s risk assessment tracker, the level of infections in the U.S. is currently twice that of France, three times that of Spain, and more than five times that of Italy.

Quarantine-free countries

As of August 15, 2021, with the implementation of the vaccine passport, many countries are easing their quarantine requirements and making allowances to accommodate international arrivals. While the following countries do provide a quarantine-free travel experience, please note that in most cases waiving the quarantine period is contingent on the testing and/or vaccination status of the traveler. The following is our selection of the top countries that do not require visitors to quarantine. Jordan Jordan’s generosity and hospitality are simply boundless—since ancient times, the land has always been welcoming to countless strangers and visitors. As such, not even the pandemic can stop you from paying your respect to Jordan’s ancient rock city of Petra.

The test result for passengers arriving from Egypt, Turkey, and Iraq must be issued by an approved laboratory, details can be found on https://www.visitjordan.gov. jo/Labs-List.html Any non-Jordanian travelers departing from India will not be granted entry unless they have stayed for 45 days outside India prior to travelling to Jordan. Additionally, travelers who have been in Nepal, Bangladesh, Pakistan, Bhutan, Myanmar, and Sri Lanka will not be granted entry. The Maldives If your vision of paradise involves an untouched tropical island with waving palm trees, white, dreamy beaches, and shimmering turquoise lagoons, the Maldives will definitely not disappoint. It’s also a haven for scuba divers with its beautiful coral reefs and teeming undersea marine environment. Unless you’re arriving from the UK, fully vaccinated travelers will not be subjected to quarantine. As for visitors from other parts of the world, no quarantine requirement is necessary, as long as they are in possession of a medical certificate with a negative Coronavirus (COVID-19) PCR test result. The test must have been taken at most 72 hours before departure from the first embarkation point. Travelers must complete a Traveller Health Declaration at most 24 hours before departure. Dubai (United Arab Emirates) Dubai is the place for you if excellent restaurants, fine spas, international shopping, luxury hotels, and alluring nightlife constitute your idea of the perfect getaway. In other words, Dubai appeals to foodies, shoppers, lovers of art, and those simply looking to have some fun. Dubai also boasts some local flavors with its laid-back ambience of the traditional souks, its art galleries, as well as local gastronomy. With its incredible array of offerings, you will find Dubai catering to both simple living and luxurious lifestyles alike. 28 ROTOWORLD® AUGUST-SEPTEMBER 2021

In the case of Dubai, foreign tourists from certain countries are allowed entry with no on-arrival quarantine imposed should they should able to meet the necessary requirements. However, tourists departing from the UAE’s list of banned countries will not be granted entry. All passengers travelling to Dubai from any other point of origin must hold a negative COVID 19 RT PCR test certificate for a test issued within 72 hours prior to departure. Depending on your country of origin, you may need to take another test upon arrival. Children under the age of 12 and passengers who have a moderate or severe disability are exempt from taking a COVID 19 RT PCR test. Seychelles This jewel in the Indian Ocean is one of the most sought-after destinations in the world. No traveler worth their salt can truly resist the temptation of sparkling beaches scattered perfectly across the country’s 115 islands. But in the off chance that the beaches fail to enchant travelers, the Seychelles lush jungle featuring scores of fascinating wildlife will surely do the trick. Seychelles is open to travelers from all over the world. However, for the time being, visitors from South Africa, Brazil, India, Pakistan, Nepal, and Bangladesh will not be granted entry. Fully vaccinated status is not mandatory, although travelers are strongly encouraged to have been fully immunized prior to travel. A Health Travel Authorization (HTA) is required for every passenger entering Seychelles along with a negative PCR test taken maximum 72 hrs before departure Mexico Mexico boasts lush tropical forests, cacti-infected deserts, as well as sandy beaches and lagoons. As such, visiting the country means availing yourself of its various activities of the great outdoors.

Reducing Gas Dependency in Rotomoulding – What Are Our Options?

Image courtesy of AMS Belgium

In the previous edition of RotoWorld® I raised the alarm that rotomoulding as we know it is under long-term threat, due to our industry’s reliance on cheap, efficient, and readily available natural gas. The world is rapidly turning away from fossil fuels and country after country is announcing new measures to reduce carbon emissions and promote greener forms of energy. A good example is New Zealand’s proposed total ban on all new installations using natural gas. What is our industry going to do? In my last article, I talked about the possibility of converting conventional rotomoulding machines from gas to electrically heated ovens. This is happening on a limited scale, but the ovens are more expensive to buy and to run and there can be practical difficulties relating to the very high electrical load requirements at start-up. There are some novel solutions being created to overcome 30 ROTOWORLD® AUGUST-SEPTEMBER 2021

some of these issues. Dhanu Patell at Reinhardt Teknik in India is developing a hybrid machine, which uses diesel or gas for the ramp-up, to avoid the connected load problem with electricity, and then the machine switches to run on electricity which is sometimes generated ‘in-house’ from solar. Another option to consider is bio-gas. This is a growing renewable source of fuel that is produced from the breaking down of organic matter, such as food scraps and animal waste. There is much talk in places like New Zealand about replacing natural gas with biogas, but clearly the infrastructure to produce this is considerable and not within the control of the rotomoulder. Biogas is also just a stepping stone to a zero-carbon world as burning this energy source still produces CO2. Are there other creative solutions? Oven-less rotomoulding? If you take away the need for the oven and you directly heat the mould then you are going to need to use less energy. Is this the solution?

AT ISSUE Heating moulds using jacketed hot oil has been done for many years and more recently electrically heated moulds have become increasingly popular. Pioneers of this technology have been Persico in Italy with their SMART machine and AMS in Belgium with their Robomould concept and other companies are working on similar concepts. These non-conventional machines are becoming more commonly used across Europe and I’m starting to see them in other parts of the world too, particularly for the production of really top-end, high value, and smaller-sized rotomoulded parts. There are many advantages, as you can have much more accurate control of temperatures which opens up the use of many more materials, and have various temperature zones across a mould which allows you to have variable wall-thicknesses in different sections. These technologies help moulders make parts with tighter tolerances and can deliver sizeable reductions in cycle times. And of course, they use much less energy. Could electrically heated mould technology be the solution to our industry’s potential energy crisis? As things stand my view is that electrically heated mould technology will continue to grow rapidly, however, the relatively high capital expenditure of the machinery, and perhaps even more importantly, the higher cost of moulds will mean that this type of process will remain niche. Currently, there are also limitations on the size of products that are being produced and there isn’t the degree of flexibility to produce short runs of products that you get with conventional equipment. For it to become more mainstream the costs would have to come down considerably and the process is simplified. Perhaps this is an opportunity for someone to develop?

exhaust; use air movers or transvectors to concentrate heat on certain parts of the mould to increase wall-thickness and use less material overall; have better air circulation within the oven; use faster sintering powder; and heat the powder before moulding. In the past, I think people were not particularly motivated to look at these kinds of things as the cost of gas has been cheap and minimising its use has not been a priority. Certainly, I’ve seen profligate wastage including witnessing a Production Manager firing up an idle rotomoulding oven so that he could heat up his pie! Perhaps attitudes will now start to change as we all become much more aware of our CO2 footprint and our responsibility

Improve efficiency and use less gas? Now, we don’t have a “silver bullet”, one solution that solves all our future problems. Whilst electrically heated moulds might be of growing importance moving forwards, what about now? I think most rotomoulders would accept that the conventional gas oven machine is energy inefficient and most open flame machines are even more wasteful. It’s been estimated that the overall efficiency of our industry (amount of energy used to process vs. kilograms of the finished product) is in the 3-8% range. So, there must be plenty of scope to improve the efficiency and waste less gas. There are many things rotomoulders can do to improve energy efficiency, such as reduce heat loss in ovens by having better seals; use more efficient burners; reuse the energy from the oven

to not squander precious finite resources and to minimise our harming of the environment. As an industry, we need to face up to the fact that we have a long way to go as far as energy efficiency is concerned – and this is going to become a much bigger issue very soon. Whilst energy efficiency is currently a “D minus” and “must do better”, rotomoulding is making many positive contributions to the environment and improving people’s lives. In the next edition of RotoWorld®, I will be examining some of these and discussing how important it is for us to promote the benefits of our industry to our customers, colleagues, and the wider world. www.rotoworldmag.com 31

Rotate for the

Clouds

Ian Hansen, Rota Consult

38 ROTOWORLD® AUGUST-SEPTEMBER 2021

Two clouds chairs, one white and one blue, located in the central White Cloud Court. 两张云朵座椅位于中央的白云庭院，一白一蓝。

The cloud seat, designed for Starway in China, combines perfectly European spirit of simplicity and elegance of the East, to produce a sense of luxury to outside spaces. 20 yrs ago the China rotomoulding industry was basic containers and tanks, mainly using simple equipment and moulds. In 2005 representatives from SPE Rotomolding Division, ARM, ARMA and what is known today as StAR, attended the first China rotomoulding forum in Shanghai. This is when China founded their own national rotomoulding committee, (RPC-CPPIA) as a separate association within their national plastics association. One of their primary goals was to catch up with the rest of the rotomoulding world. I would like to give you a glimpse of their progress. The China rotational moulding industry has been changing rapidly since 2005. I have attended multiple rotomoulding conferences and ‘Rototours’ within China to improve my understanding of the local industry. ARMA began holding annual conferences in the Asian region in 1997, beginning with Indonesia. In 2005 the ARMA annual conference was in Hong Kong, which coincided with one of the first ARMA organised tours of China rotomoulding factories. Regular readers of Rotoworld® may recall that Bill Spencley of Flexahopper Plastics wrote an article in the July-August 2015 issue highlighting the

由中国的星威国际家居股份有限公司设计的云朵座椅，完美地结合了东方简约与欧式优雅，由内而外得带来一种奢华感。 20年前，中国的滚塑行业主要使用简单的设备和模具来制作比较基础的容器和水箱。2005年，来自SPE滚塑部门、ARM（美国滚塑协会）、ARMA（大洋洲滚塑协会）和StAR（印度滚塑协会）的代表参加了在上海举办的首届中国滚塑论坛。正是在这个时候，中国成立了自己的滚塑协会，即中国塑料加工协会滚塑专委会(RPC-CPPIA)。该协会是中国塑料加工协会下属的一个独立协会，主要目标之一就是要追赶世界范围内的其他滚塑公司。我来为你们简单介绍一下他们的进展。自2005年以来，中国滚塑行业一直在快速变化。我数次拜访中国，并参加了多次滚塑会议和实地企业考察，以提高我对当地行业的理解。ARMA从1997年开始在亚洲地区举行年会，最早在印度尼西亚举行。2005年，ARMA年会在香港举行，这是ARMA 第一次组织参观中国的滚塑工厂。Rotoworld的老读者可能还记得Flexahopper Plastics的Bill Spencley在2015年7 - 8月的一期上写过一篇文章，强调了中国滚塑行业的成长和发展。2017年ARM/ ARMA在夏威夷联合举行论坛之前，ARMA再一次组织全球滚塑精英及专家到中国参观工厂。2021年，中国显然已经有越来越多的企业宣称自己正在赶上世界其他地区的滚塑发展。星威国际家居股份有限公司（以下简称星威家居）是一家集研发、设计、制造、销售为一体的现代化企业。产品涵盖塑料家具、木制家具和软垫家具三大领域。公司总部位于中国浙江省。 www.rotoworldmag.com 39

growth and development of the rotomoulding industry in China. ARMA returned to tour China factories in 2017, prior to the ARM/ARMA Joint Forum in Hawaii. In 2021 it is clear that there are more and more businesses in China who can claim they catching up with the rest of the world. Xingwei International Home Furnishing Co., Ltd. (Starway) is a modern business integrating R&D, design, manufacturing and sales. Its products cover three major areas: plastic furniture, wooden furniture and upholstered furniture. The company is headquartered in Zhejiang Province, China. It has more than 1,000 employees and an annual turnover of more than USD75 Million. Starway’s innovation legacy began in 1988 with a plastic chair, and for the past 3 decades they have employed a design led philosophy, using new technology and new material to stay on the forefront of product design for the furniture industry. Bringing European inspired outdoor furniture to China, and the world, was the heart of Starway’s beginnings in 1988. Since then, they have worked alongside some of the worlds’s

公司现有员工1000多人，年营业额超过7500万美元。星威家居的创新传统始于1988年的塑料椅子。在过去的30年里，他们坚守以设计为主导的理念，依靠新技术和新材料在家居行业产品设计领域保持前沿优势。将欧洲风格的户外家具带到中国和世界，是星威家居于1988 年创立的核心。从那时起，他们与Stefano Giovannoni, Derby Xu, Enrique Marti等世界领先的设计师合作，建立了一家提供现代和卓越的室内及室外家具的公司。大约15年前，上海的建筑师们开始摆脱上世纪90年代建筑热潮期间盛行的西式风格，开始寻找适合21世纪中国自己的建筑代名词和特色。与大多数伟大的设计一样，云朵座椅设计乍一看可能很简单，但在项目开发中投入了大量的时间和精力。俞挺，2013年Wutopia Lab的联合创始人，为朵云系列书店提供了建筑设计，包括朵云在上海的旗舰店。该旗舰店位于上海最高建筑上海中心大厦52层，面积达2230平方米，是一家真正在云端的书店。 “建筑是我们的思想理念与设计完美糅合碰撞的好机会。通过新材料，我们试图给人们带来美丽的空间。这份工作最有价

leading designers such as Stefano Giovannoni, Derby Xu, Enrique Marti, to build a company that delivers contemporary and exceptional indoor and outdoor furniture. About 15 years ago architects in Shanghai began to break away from western imitation, which had been prevalent during the 1990’s building boom, and began to search for their own architectural vocabulary and characteristics for 21st century China. Like most great designs the cloud seat design may appear simple at first glance, but there was a lot of time and effort invested in project development. Yu Ting, co-founder of Wutopia Lab in 2013, has designed stores for Duoyun Books, (Cloud Books) including their 24,000 sq ft flagship store which is located literally above the clouds on the 52nd floor of Shanghai’s tallest building, Shanghai Tower. “Hospitality is a good opportunity for us to link our thoughts and designs. Through new materials, we are trying to bring people beautiful spaces. The most rewarding part of the job is that you can make your imagination come true.” Yu Ting explains. Wutopia recently designed a 2 level 18,500sq ft Duoyun Bookstore in Huangyan, which opened for business in June 2021. Yu Ting had a vision of a cloud slowly rising over and above the Yongning River, where the bookstore is located. The building is wrapped in white aluminium panels to give the feeling of looking at a drifting cloud from a distance. The cloud shaped seats used inside the central courtyard and outside on the riverside terrace are designed to immerse the customer in a dream, where the busy outside world ceases to exist. Two coloured cloud seats were a part of the vision, one white and one blue.

值的地方在于，你可以让你的想象变成现实。”俞挺解释道。 Wutopia Lab最近在浙江黄岩设计了一个2层的共计 17200平方米的朵云书店，该书店已经于2021年6月开业。站在永宁江畔，俞挺仿佛看到了缓缓升起的云朵。于是，他改造了外立面，白色帷幕仿佛纯净的面纱，将三栋建筑包裹起来，给人一种从远处看到飘浮的云的感觉。放置于中央庭院内和外面河边露台上的云朵座椅，旨在让顾客沉浸在一个梦想中。在那里，繁忙的外部世界不再存在。两个彩色的云朵座椅是画面的一部分，一个白色，一个蓝色。星威家居确认了云朵座椅的滚塑成型可能性后，联系了中国浙江省温岭市旭日滚塑科技有限公司(以下简称旭日滚塑)。星威家居已经有滚塑成型加工经验，并拥有由旭日滚塑生产的塔转式3臂滚塑设备3A-2500，所以很熟悉滚塑成型的优势。两家公司共同完成了云朵座椅的设计，其中包含两种不同的尺寸，也完美结合了独特的白色和蓝色斑点。星威家居提供了云朵座椅的设计概念给旭日滚塑，旭日滚塑的团队据此设计出最终的模具结构细节，以适 www.rotoworldmag.com 41

Starway was able to imagine the possibilities of rotational moulding for the design, and contacted Wenling Rising Sun Rotomolding Technology Co., Ltd (Rising Sun) in Zhejiang Province, China. Starway already had a 3 arm 2.5m (98”) Rising Sun carousel oven, so were familiar with the advantages of rotomoulding. Working together they finalised the cloud seat design, in two different sizes incorporating a unique speckled white and speckled blue colour. The design brief revolved around the customer requirement for only a very few seats, as the seat compliments the new Duoyun bookstore designs. Starway provided the cloud seat design concept to Rising Sun engineers who helped work out the final mould construction

应成型需求。因为书店需要的云朵座椅数据非常有限，所以滚塑成型以及滚塑钣金模具是最理想的加工方式。模具上旭日滚塑采用低碳钢制作，容易成型，而且交期相对较短。为了满足客户不同规格的座椅要求，旭日滚塑共制作了两套模具。一套模具用于制作小型的云朵座椅，而另一套模具是由三个独立的不同形状的模具组成，其相应的成型塑料件连接在一起，会变成一个更大尺寸的朵云座椅。旭日滚塑不仅制造滚塑设备和模具，他们也为客户提供代工服务，以帮助企业把他们的设计变成现实。对于星威家居目前拥有的设备来说，云朵模具尺寸较大，所以无法在他们自己的设备的生产。因此他们委托旭日滚塑来帮忙生产，旭日也在他们的穿梭4m滚塑设备上完成了产品的加工。穿梭式滚塑设备是生产小批量产品最理想的设备，适用于多层产品

details to suit the moulding process. The limited production number was ideally suited to rotomoulding and favored a fabricated sheet metal mould. Using mild steel, the shape was easy to form and enabled a quick mould lead time. Two different mould designs were manufactured to meet the customers specifications. One mould was fabricated in one piece to make the small seat while another set of moulds were fabricated in two separate pieces. 3 moulded segments are joined together to make one larger cloud seat. Rising Sun not only manufacture moulds, and rotational moulding machines, they also offer a contract moulding service to assist businesses turn their designs into reality. 42 ROTOWORLD® AUGUST-SEPTEMBER 2021

生产，复杂的脱模或重新装料。该产品选用的树脂为常规的LLDPE聚乙烯。然而，为了达到设计师所要求的色彩深度，产品由多次投料加工而成，即产品为多层。蓝色座椅由蓝色树脂和可回收材料组合而成，而白色座椅也由白色树脂和可回收材料组合而成。将回收材料与滚塑成型工艺完美结合，反映了设计师在其创作中可持续设计意识的日益增长。星威家居与旭日滚塑有着非常牢固的合作关系，他们专注于质量，开发和改进工艺，也对滚塑成型有着非常深刻的了解。虽然这篇文章是关于星威家居和他们使用滚塑成型制作的户外家具，但是我们滚塑行业应该记住，随着新技术的持续问世，我们也必须投资产品的质量研究，从而利用新技术保持竞

The cloud mould was too big for the Starway carousel oven so Rising Sun moulded the parts in their own 4.0m (157”) shuttle oven, specifically available for contract moulding situations like this. Shuttle machines are ideal for short production runs multilayer materials or complex demoulding or reloading processes. The resin selected for the part was a general purpose LLDPE polyethylene. However, it was a multiple layer system to achieve the colour depth required by the designer. The blue seat has a combination of blue resin and recycled material while the white seat also has a combination of white resin and recycled material. The requirement for recycled material to be included in the rotomoulding process reflects the growing awareness of designers to express sustainable designs in their creations. Starway are an example of a business which builds strong relationships with manufacturing partners, focusing on quality, developing and improving processes, while embracing the advantages of new technologies - such as rotational moulding. While this article is about Starway and their use of the rotational moulding process for outdoor furniture, our rotomoulding industry should remember that as new technology continues to emerge we must also invest in quality research so we can utilise new technology to remain competitive. In Rotoworld® Issue 6 2020 Paul Nugent reminded us of the late Prof Roy Crawford’s “Vision 2020” published in 2000. Nugent highlighted innovations like wireless mould temperature control, (introduced in 1990 by Crawford and Nugent with the Rotolog system), has had low industry adoption and utilisation. In China, rotomoulding companies like Rising Sun have also recognised the value of this technology and from 2015 they started to offer their own wireless internal air temperature measurement system to their customers. Some Chinese companies are indeed catching up with the rest of the rotomoulding world. Rising Sun was established almost two decades ago, in 2003. They now manufacture and export a wide variety of machines from basic Rock & Roll open flame to high performance shuttle and carousel biaxial ovens up to 6.5m diameter. Rising Sun attend or exhibit at rotomoulding conferences around the world, and are members of industry associations such as ARM, ARMA, and their own national RPC-CPPIA.

争力。在《Rotoworld》2020年第6期中，保罗·纽金特(Paul Nugent)让我们想起已故罗伊·克劳福德教授(Prof . Roy Crawford) 2000年发表的《愿景2020》。纽金特强调了一些创新，如无线模具温度控制(由克劳福德和纽金特于1990年通过Rotolog系统引入)，但其工业采用率和利用率很低。在中国，像旭日滚塑这样的滚塑公司也认识到了这项技术的价值，并于2015年开始向客户提供了自己的无线内部测温系统。我们可以说一些中国企业确实在追赶世界范围内的其他滚塑企业。旭日滚塑成立于2003年，距今已近20年。他们生产和出口各种各样的机器，从基本的摇滚明火到高性能的穿梭和塔转式滚塑设备，最大的烘箱直径达6.5米。旭日滚塑在世界范围内都非常活跃，他们积极参与世界各地的滚塑会议，并且也是ARM, ARMA 的成员，也是他们自己的国家RPC-CPPIA的副主任单位。来自他们公司的Sharon Zhu也是RPC-CPPIA秘书处的秘书之一。伊恩·汉森在滚塑成型行业有超过30年的经验。他是ARMA 的前任主席和公认的行业偶像。他曾在世界各地的滚塑成型会议上发表演讲，经常以罐体设计标准、质量和安全为主题。他目前通过他的咨询公司Rota consulting为全球滚塑应用提供咨询服务 www.rotoworldmag.com 43

A lot has happened in the rotational molding industry over the past 2 years. During this time COVID-19 caused a stranglehold of virtually every country and economy around the world.

“It would take a brave person to predict the future of our industry, or any industry for that matter, during these volatile times. What we do know is that demand remains strong and what sets us apart has not changed.”

Prior to COVID, the rotational molding industry was in a strong position, with many sectors enjoying healthy growth. Material prices were reasonably stable, helping molders to be competitive with other processes. The industry was surging and the future looked good, with one major exception being the tight labor markets in the established regions of the world making it exceptionally difficult to fill open positions. Also, the manufactured product value per labor hour ($/hr.) was in decline in the US and there was much discussion about the need to automate to reduce labor content and improve efficiencies. In early 2020, the world as we knew it changed as the coronavirus spread and death tolls started to rise. It was a moment in time that we will never forget as the tragic stories of the victims emerged, many of whom were elderly and/or had pre-existing medical conditions. Sadly, some well-known figures within our industry lost loved ones. At that time manufacturing in general was greatly impacted, as the spread of the virus resulted in the need to protect employees. World economies started to rapidly slow down and many molders quickly went from normal business levels to a significant reduction in orders. Having enough labor was no longer an issue and the situation remarkably switched to having too much labor. Molders had to realign staffing levels to new reduced demand levels. This helped to sustain profitability for many companies during 2020, but the economic environment was about to change again and molders had to react quickly to meet the challenges.

The Challenges of COVID-19 and the Bounce Back! The remarks to follow will focus mainly on what has happened in the US but could well apply to many other regions of the world.

I suspect most molders have found the last 12-18 months to be some of the most challenging times in their company’s history. It’s been a remarkable period of time, as we all have had to react to a dynamically changing environment, much of which has been out of our control and not predicable. Looking back, it really has been an incredible journey filled with lots of unknowns that we have had to navigate our way through. Here are some that come to mind: How COVID was initially managed in the workplace Between February and April of 2020 everyone had to come to terms

with the new world we now lived in, dominated by the news of the spreading “Coronavirus” or “COVID-19” and rising death tolls. Italy was one of the first countries hit hard by the virus and the newscasts from the northern region of Italy being shared across the world were horrifying. One of our industry’s leading mold makers (Persico) was right in the middle of the epicenter and many of their associates tragically lost loved ones. Every business in the world quickly began to focus on trying to understand what COVID-19 is, how contagious is it and how should businesses continue to operate while providing a safe and healthy work environment for employees? This was something new that no one had dealt with www.rotoworldmag.com 45

before. There was no playbook for a pandemic, we had to create our own and learn from others around us. In many ways it became a “common cause” that team members rallied behind. We were all in this together, everyone’s health became the priority and we needed to establish guidelines for our associates to protect them and protect our businesses. Every business understands the need to continue to manufacture in order to remain solvent. Over the next few months everyone’s business changed in some way to meet regional government guidelines and to protect their workforce. A period of moderate stability! During the fall/winter of 2020 we all began to embrace “the new

looking to the outdoors as a source of relaxation and enjoyment. It resulted in many people being attracted to “safe” outdoors sports and activities such as boating, canoeing, kayaking, camping, use of RVs and many other pursuits. Molders, mold builders and material suppliers who supported these industries realized an unexpected market surge which they gratefully responded to. There was also a great consumer transition to online shopping, and molders who supported these markets also boomed during this time, while other sectors such as agriculture and construction saw a decline. It was a mixed bag, and no one really knew what the future held. For those who were busy, labor was reasonably available (at least in the US). However, as the year came to an end, there were growing concerns globally for rotational molders that material pricing was on the rise, and no one knew when this might change. The turbulence of the last 9 months It’s hard to put into words the turbulence of the last 18 months and especially the last 9 months. For many, the last 9 months have

norm”! Life had changed, manufacturing had changed, masks were commonplace, in-person interaction was difficult, virtual meetings were common and working from home was available to many who were not directly involved in manufacturing. We all adapted and moved forward, doing the best we could to manufacture to reduced order levels – at least for some molders. At this time there were certain market sectors that boomed. These included lawn & garden, as well as the outdoor and consumer product groups. With many people either not allowed to travel or not willing to risk traveling, this led to many focusing on home and yard improvements and 46 ROTOWORLD® AUGUST-SEPTEMBER 2021

thankfully seen a surge in business, but this increase in demand has not been without its challenges. Normally business growth is something to embrace and enjoy, as it is healthy and important for any business to grow. However, growth during the current economic climate is probably more challenging than at any time in the past. There are several reasons for this: • The speed of change – part of the problem is the speed at which economies and business demand have changed. Initially many businesses had a very quick slowdown in trade. Now, many product sectors are back to full volumes and several with increased annual volumes. With rotational molding being labor intensive, it is very challenging to staff up quickly, add capacity and develop the necessary workforce skills to be operationally successful.

• Government incentives – during the pandemic, many people lost Complex products require complex molds. Mold makers are their jobs and were dependent on welfare from the states. This becoming more and more creative as they find ways to provide clearly has been a difficult time for many people in many ways. the industry with the complexity of tooling required. CNC molds The government stimulus package resulted in unemployment continue to grow in popularity, typically providing the highest benefits being boosted. While well intentioned, these increased quality of mold. Electrically heated molds offer more precise heating, benefits quickly became counter-productive, as employers providing molders with options to minimize the amount of raw desperately needed more workers, only to find that typical pay material required to produce the part, reducing part price. For very rates could barely match the unemployment benefits. As a result, complex geometries the mold may need to be manufactured from many potential workers opted to receive unemployment benefits several pieces to allow demolding of the part. These loose pieces can rather than return to the workforce. be mounted on sliding guides to minimize parting line wear. • Resin pricing – the primary cost driver of any rotomolded part Polyethylene (PE) continues to dominate the type of raw material is typically the polymer used to produce it. For the past 9 months most used by the industry. As we all know PE has its limitations, or more, the cost of resin has increased monthly. This has been but there are a wide variety of grades available which have helped driven by material shortages and some unexpected capacity to establish the industry in several market sectors. These sectors issues in the supply chain due to inclement winter weather and include water and chemical storage tanks, toys, playgrounds and manufacturing plant mechanical issues. Molders literally have never experienced anything like the current price escalation. The knock-on effect is how to pass this on to customers quickly enough to sustain profitability. With no relaxation of resin pricing this continues to be one of the greatest challenges that molders must work through to remain solvent. • The uncertain supply chain – as if escalating resin pricing is not enough, many molders have been battling supply chain issues. Just like rotomolders, the supply base has struggled to react quickly enough to the increases in demand that many are experiencing, combined with the shortage of labor. Many of us who have been involved in manufacturing for a long time are familiar with the term “force majeure”, but I suspect we have not heard it used with such frequency as we have during the past 9 months. Not having the materials we need when we need them, drives tremendous chaos into the workplace, forcing mold changes, downtime, and “Yes, there are no doubt great challenges ahead undesirable line-down situations. This is becoming for the industry, but there are also great rewards more accepted, and it remains uncertain as to when this situation is likely to change. for those who can find solutions to the problems

What does our future hold?

that we face and make rotational molding jobs more appealing to the younger generations, while minimizing the need to work overtime to meet production schedules.”

It would take a brave person to predict the future of our industry, or any industry for that matter, during these volatile times. What we do know is that demand remains strong and what sets us apart has not changed. We are blessed with a process that has a special niche in the plastics world, with certain capabilities that are not easily matched. Many rotationally molded products are either too complex or too large for other processes to competitively manufacture. Rotomolded products can be highly complex, 3D geometries, as a result of product designers combining several components into one roto part, creating a high value product. 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 their customers.

fitness equipment, fuel tanks, floatation, and insulated products, material handling, waste disposal, and floor cleaning products [1]. The real challenge! 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. Remarkably, having gone through what we have experienced in the last 18 months, the industry now finds itself back at the exact same position as 2 years ago, not www.rotoworldmag.com 47

having enough labor to manufacture the parts. As labor costs rise and as labor becomes less available in 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. Another efficiency opportunity is to minimize machine downtime due to mold changes. This is something that all molders are faced with, that results in lost productivity from the machine and of 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 manage 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. While automation is not always easy or straight forward, the justification to make these investments will become easier as labor costs rise, production demand increases, and as labor becomes less and less available for these types of manufacturing positions. Hopefully the coming months will see a reduction of resin pricing to help the industry stay competitive, as many fear the increases in product costs that have been passed on to customers in recent months will result in a loss of business long-term.

Yes, there are no doubt great challenges ahead for the industry, but there are also great rewards for those who can find solutions to the problems that we face and make rotational molding jobs more appealing to the younger generations, while minimizing the need to work overtime to meet production schedules. Molders who want to survive and even grow during these challenging times are simply going to have to pay more to attract the right talent for these types of manufacturing positions. Staffing, managing the impact of rising labor cost, resin costs and other inflationary costs are the real challenges that the industry faces, as automation will never be a complete solution for many molders/applications due to part size, complexity, variation, low volume etc. Therefore, focusing on the work environment, production methods, training, equipment/tools, ergonomics, engagement, teamwork, career growth and compensation needs to be a greater priority to attract good employees and make them feel that manufacturing is a career worth pursuing. Rotomolding truly is one of the few industries where someone can leave high school and build a career to become a successful manufacturing operations leader with great reward potential!

DESIGN

COMMENT

Michael Paloian, Integrated Design Systems, Inc.

Designing for the Long Term Product design is very fulfilling as well as challenging. It feels great to be able to think of something, sketch it out on a piece of paper, maybe make a model, then translate your idea into an actual product! One of the most challenging responsibilities for a designer or engineer is designing a product for the long term. This process requires in-depth knowledge in materials science, manufacturing, physics, mechanics, aesthetics, human factors, and application. It would help if you had a crystal ball when designing a product to last for 5, 10, or 20 years. Unfortunately, none of us have a reliable means of looking into the future unless you subscribe to a fortuneteller. So how do you design a product to last for a specified minimum timeframe? There are a few basic requirements for designing long-lasting products as listed below: • Know your material • Understand the product application • Manage stresses and loads • Always account for the environment • Never assume anything Understanding Material Properties Knowledge of material properties cannot be over-emphasized. Long-term performance is highly dependent on material properties, and how well matched they are to the applied loads, chemicals, radiation, and thermal conditions to which they are subjected. Engineers need to evaluate the extremes of these parameters based on the specified material and anticipated operating conditions. Although this may appear to be straightforward, it is quite the opposite. An engineer must carefully expect every possible use condition for a given product and evaluate its performance based on a combination of conditions. Unfortunately, most published material data is limited to immediate loads. This limitation requires product designers to conduct accelerated testing based on sound engineering principles. Understand the Product Application Although this may appear to be elementary, it is a critical and often overlooked step in product design. Understanding the application requires understanding the interrelationships between product use, misuse, use environments, maintenance, and safety. For example, a product exposed to sunlight for up to ten years requires excellent UV resistance. Specifying a UV 10 grade of polyethylene means that it will retain a minimum of 50% of its tensile strength and impact after this exposure period. Therefore your device should be designed to withstand a minimum of two times the loads from time zero.

Manage stresses and loads Stresses and loads should also account for creep, which is time and temperature-dependent. For example, a water tank can be filled and perform well at room temperature and time zero. However, it could fail after two or five years under constant load and higher temperatures. This phenomenon is attributed to creep. Creep is a change in modulus over time under constant load. Always account for the environment The environments of use are critical to assess when designing for the long term. Product environments could include harsh chemicals, which could rapidly degrade plastics. Environmental conditions also influence radiation such as UV, or X-rays, gamma rays, etc. Thermal conditions are another common environmental consideration. Electrical energy is also crucial since it will affect designs requiring insulation which is dependent upon dielectric strength. Never assume anything The last important consideration for designing for the long term is never to assume anything. Assumptions often lead to a false sense of security based on omissions of critical design considerations. Omissions lead to errors and premature product failures, which is why the US courts are backlogged with thousands of lawsuits every year based on “Errors and Omissions.” Critical due diligence is essential in any design methodology where long-term product performance is required. I hope this brief editorial was informative and somewhat enlightening. It is intended to alert you to the challenges associated with designing products to last long periods. This topic would be an excellent subject for a book. If you have any comments or would like to reach me, please feel free to contact me at paloian@idsys.com. www.rotoworldmag.com 49

Chemical Tanks: Knowledge is Power Ian Hansen, Rota Consult

When it comes to chemical or industrial storage tanks, many rotomoulders use their existing water tank moulds to make tanks to store a variety of chemicals, usually with minor design changes. This article attempts to provide information and guidance primarily on the polymer properties which moulders should be aware of when designing a chemical tank fit for purpose. In the beginning When tank capacities are small, the risks are relatively small. When the tank size increases in capacity, then any small deficiencies in design can become magnified. A tank designed to hold 3,000L (800USG) of water (or chemicals) will almost by accident rather than design, have a greater design factor of safety than a 30,000L (8,000USG) tank. Polyethylene tanks are used around the world for the bulk storage of industrial chemicals, including dangerous and corrosive chemicals like hypochlorite solution (liquid ‘pool chlorine’) and hydrochloric acid. Bulk storage tanks for diesel, liquid fertilisers and molasses are commonly used by the agriculture industry. When storing chemicals, the damage (real cost) caused by failure (leak) can be significantly greater than for a leaking water tank. In countries that have robust rotomoulding tank standards for material, design, manufacture and postproduction testing of tanks, the suitability of the tank structure would be assessed using finite element analysis (FEA) to ensure

the tank is fit for purpose (see Figure 1). AS/NZS4766 is an example of such a comprehensive tank standard. Some standards provide general guidance about chemical tanks. Typically, the suitability of the polymer for chemical storage should be based on relevant chemical resistance data from polymer manufacturers. Moulders relatively new to chemical storage tanks need to be aware that ESCR (stress-cracking test) is not recommended to be used as an indicator of general chemical resistance of a polymer. The moulder should maintain relevant chemical resistance/performance data demonstrating the tank’s suitability for the intended application. Responsibility Generally speaking, the manufacturer of the storage tank is normally responsible for the evaluation of both the tank design and chemical resistance of the polymer material to ensure the tank can withstand chemical attack, with minimal change in appearance, dimensions, mechanical properties, and weight over a period of time. The degree of responsibility in the event of product failure will depend on the regulations and legal precedents of the region the tank is produced or sold into. To put this into perspective, there have been a couple of major court cases where moulders have unsuccessfully claimed the polyethylene supplied had: • inadequate environmental stress cracking resistance. 2008 judgement, US$70M claim [1] • inadequate ultra-violet light (UV) resistance. 2012, US$50M [2] These expensive disputes, involving combined claims of about US$120M, highlighted the primary importance of design, processing and quality control which the moulders were found responsible for, not the quality of material used. This article provides an introduction to the design changes to consider in managing the effects of storing bulk chemicals rather than water. Chemical Effects Chemical resistance encompasses the total effect a product would have on a storage tank. The 3 key factors that make up the overall compatibility of a chemical to a polyethylene tank are: i. Chemical Attack - Oxidation ii. Stress Cracking - ESCR iii. Permeation – Plasticisation

Figure 1: FEA highlighting acceptable stress around tank and unacceptable peak stress at the outlet

50 ROTOWORLD® AUGUST-SEPTEMBER 2021

(i) Chemical Attack Oxidising agents undertake a chemical attack by chemically degrading the polyethylene. This can be a breaking of molecular chains and/or an addition of chemical groups to the molecule.

Oxidisation causes the eventual loss of properties with the plastic becoming brittle and the tank not fit for use. This would be similar to steel rusting/failing or wine turning into vinegar. Chemical effects may be gradual and may not be measurable over the short term. Examples of strong oxidizers which potentially may be unsuitable for long term exposure to polyethylene include nitric acid & sulphuric acid.

grades approved for storage of diesel (ECE-R34) still require the moulder to consider design and wall thickness changes to manage the softening of the polyethylene. Figure 3 illustrates a diesel approved grade of polyethylene after more than 5 years of service. Examples of plasticising chemicals which may be unsuitable for long term exposure to PE include petroleum, gasoline, benzene or other aromatic hydrocarbons.

(ii) Stress Cracking Environmental stress cracking is the cracking of a polyethylene part under stress when in contact with a medium, e.g. kerosene, in the absence of which surface initiated micro cracks or fractures do not occur under the same conditions of stress. The polymer’s resistance to such failures is called environmental stress crack resistance (ESCR). A diluted chemical (10%) will normally have a greater effect than a full strength (100%) chemical. Consider diluted detergents such as dish washing liquid. This stress cracking can often be accelerated when combined with elevated operating temperatures. Figure 2 illustrates an example of a stress crack failure. Examples of known stress cracking agents which may be unsuitable for long term exposure to polyethylene include detergents, surfactants and vegetable oils. Figure 3: Diesel fuel permeation (brown) in a 10,000L (2,640 USG) tank

Environmental Effects Extreme temperatures can also have a negative effect on tank performance, especially hot ambient temperatures. This can be a result of external heat from the sun, or it can be internal from hot liquids entering the tank. Polyethylene, which is a flexible material, becomes even more flexible when heated. Figure 4 illustrates the bulging effect that can occur when a tank is subjected to elevated temperatures, instead of room temperature (23°C or 73°F).

Figure 2: Stress crack failure [3]

Remember, these stress cracking agents do not chemically attack the polymer. Stress on the polyethylene comes from applied forces (hydrostatic stress), part design (tight radii) and residue stress (warpage or deformation). (iii) Permeation Permeation involves the physical absorption of the chemical into the polyethylene, causing the plastic part to lose stiffness or rigidity. Additional effects include swelling, weight gain, reduction in tensile strength and loss of long-term creep resistance. Normally, absorption does not prohibit the storage of the chemical. The property losses due to permeation can usually be offset by increasing the design wall thickness of the tank or changing the type of polymer for the application. Hydrocarbon fuels such as diesel are well known to permeate into, and pass through, polyethylene over time. Even polyethylene

Figure 4: Bulging 8,000USG tank wall at elevated temperatures

The rigidity or stiffness of polyethylene is measured at a standardised temperature of 23°C. Figure 5 shows that the rigidity of polyethylene will decrease by 35% when the temperature of the material is increased from 23°C to 40°C. If a storage tank is to operate in elevated ambient temperatures, or with a liquid operating at elevated temperature, then consideration should be given to increasing the wall thickness of the product to compensate for the reduction in rigidity. Material selection The basic parameters for material selection are: i. Density (crystallinity) ii. Melt index (molecular weight) iii. Comonomer type (octene, hexene, butene)

(ii) Melt Index The influence of viscosity and melt index on material selection has been outlined in a RotoWorld® article by Alvin Spence [5]. Lower melt index materials will typically have improved stress crack resistance and chemical resistance. (iii) Comonomer The influence of comonomer type on material performance has also been previously outlined in another RotoWorld article by Nick Henwood [6]. When using low melt index material (<3.5MI) increasing from butene to hexene or butene to octene will make a significant improvement in long-term performance like stress crack resistance. When selecting a material consider the best combination of stiffness (hydrostatic load), melt index (processibility) as well as commoner (chemical resistance) to meet the functional needs of the application. Questions to ask the customer When designing any product, it is critical to have a fundamental understanding of the product’s functional requirements for the chemical tank and the customer’s intended use. • • • • • •

Figure 5: Effect of temperature on rigidity [4]

Large capacity tanks using higher density and lower melt flow polyethylene will normally have enhanced chemical resistance, while IBC’s using lower density and higher melt flow PE will have enhanced stress crack resistance. Figure 6 illustrates the two different tank applications. It is important to be aware of the advantages and disadvantages of different grades of material.

Figure 6: Different tanks usually require different performance characteristics

(i) Density Higher density materials tend to have lower stress crack resistance but are more notch sensitive than medium density materials. That is, they are typically less able to deform or yield upon impact and cannot resist crack propagation once it is initiated. 52 ROTOWORLD® AUGUST-SEPTEMBER 2021

What is the chemical being stored in the tank? What is the % concentration of the chemical? What is the Specific Gravity of the liquid? What is the service temperature range? What regulatory standards apply? What capacity is required?

While these appear to be basic questions, overlooking any one of them may result in a catastrophic failure. Therefore, it is critical to have a complete understanding of the end use application and functional requirements in order to determine the best design and optimal material/wall thickness for the application. Be aware that the moulder will normally be deemed the chemical tank manufacturing expert, not the customer. Chemical Concentration It is important to have access to chemical resistance tables which list chemicals and concentrations. Identification of multiple sources of information is also important as there may well be conflicting data and/or various concentration levels of chemicals listed. Liquid fertilizers are commonly made with nitric acid (HNO3) and are stored in bulk for agricultural use. Chemical resistance tables usually indicate nitric acid is satisfactory to be stored at lower concentrations, but not satisfactory at higher concentrations. The concentration of liquid nitrogen fertilizer, in the form of nitrate, ammonium and urea will be written on the SDS/MSDS (Safety Data Sheet/Material Safety Data Sheet). Chemical resistance tables provide general advice for polyethylene. However, not all grades of polyethylene perform the same. TOTAL compared elongation after 3 weeks of exposure to HN03, at 55% concentration, at 40°C (104°F). The polyethylene grades compared were M3421UV = mPE, XLPE = crosslinked PE, ZN-LLDPE = conventional PE. Figure 7 illustrates the performance

difference between polyethylene grades. The metallocene polyethylene (MPE) outperformed the crosslinked and standard polyethylene grades by a significant amount. This is an example of why it is important to get your polymer supplier to provide their advice on the suitability and performance of their material for your customers application. If you have a written record of this, you also have supporting evidence about the suitability of the material for a specific application. Always ensure the material supplier has all of the pertinent information relating to the application. Specific Gravity (SG) Another critical factor is the weight of the liquid chemical to be stored in the tank. Many chemicals increase in weight as the concentration of chemical increases. Some, like diesel, decrease in weight. The specific gravity of chemical concentrations should be

Figure 7: TOTAL Petrochemicals, ARMA Rotomould Conference 2008 [7]

written on the SDS/MSDS. Sodium hypochlorite (NaCIO), known as chlorine or bleach, is a chemical commonly stored around the world in many different concentrations. • 8% has SG of about 1.12 • 10% has SG of about 1.16 • 15% has SG of about 1.25 In simple terms, if your tank design required a wall thickness of 6.5mm (0.26 inch) to store water, you would need to increase it to 8mm (0.32 inch), a 25% increase, to store sodium hypochlorite at 15% concentration. This design change is just to manage the increase in weight. Note that NaCIO is also an oxidizing agent. Service Temperature A simple method most moulders use to manage the elevated temperature is to make a small increase in the wall thickness to offset the negative effect of elevated temperatures. Increasing wall thickness 25%, say from 8mm to 10mm, (0.32 inch to 0.39 inch) will yield approximately a 100% increase in rigidity (as rigidity is proportional to wall thickness cubed). Having access to performance data at elevated temperatures for the polyethylene being used, will help to correctly determine the increase in wall thickness. The material properties published by polymer suppliers are normally generated at 23°C (73°F). The good news is that most polymer suppliers will have short term tensile properties at 23°C

(73°F) and 40C (104°F). Some polymer suppliers also have longterm tensile creep properties at 23°C and 40°C. Moulders need to request this information to better predict performance at elevated temperatures. Summary Chemical effects on polyethylene that you need to understand can be divided into three categories: i. Oxidation ii. Stress cracking iii. Plasticisation Tank design and processing (optimal moulding) are interacting factors which influence chemical resistance & stress cracking resistance. Experienced moulders should already understand that some of the many factors which must be controlled for successful production of chemical storage tanks include chemical compatibility, chemical concentration, stress crack resistance, regulatory standards, operating temperature, impact resistance, vacuum or pressure conditions, duration and type (intermittent versus continuous) of operation, weatherability, design features of tank, customer installation, recyclability, overall cost, etc. This article provides a guide to some of the complex and technical issues which moulders need to consider when undertaking the risk/benefit equation presented by the storage of chemicals in tanks. For information on material selection, I would recommend you contact your material supplier for their advice on each new chemical storage application. When designing high performance chemical tanks versus water storage tanks, always design in adequate safety margins to ensure the product is fit for the application. References 1.

Mold Use Intelligence

Hopefully, answering the question…at least partially. When this issue is in your hands, we will all be meeting, sharing in our stories, our struggles, our successes, and the pleasure of all being together once again. For refresher, here again is the original question… Q: Can Industry 4.0 be used to provide the intelligence to define which molds should be run with which other molds, or combination thereof, on which arm/cart, through which oven, at what molding parameters, to achieve the best possible outcome, efficiency, part quality, and overall production results. A: I have had several discussions related to the questions that arose in the last incomplete episode 8 part 1. To come full circle, this term “Mold Compatibility” seems to be at the root of this discussion. There can be a lot of varied opinions on the factors that make molds compatible, but in the end, if a grouping of similar or dissimilar molds, seem to be compatible, then this is THE key piece of information. Evidently, it seems that in some cases, very different molds 54 ROTOWORLD® AUGUST-SEPTEMBER 2021

could indeed have similar processing windows, and therefore can be considered compatible. So…to get back to the answer for the original question. I do believe that this is an application for Industry 4.0 principles, and programming / communication from machine to machine. While this automated MOLD COMPATIBILITY platform is not yet developed and therefore not yet available, it is possible to use automation to ultimately define compatibility of a range of different molds and primary machinery. Firstly, in its eventual intended form, I believe that it could be classed as AUTOMATION as it can do what is currently achieved by a human. (automatically controlled operation of an apparatus, process, or system by mechanical or electronic devices that take the place of human labor. (An automatically controlled process or system” could be used to define this application.” While I may personally want to dispute this and argue this point, in the end it can be considered automation). While this application is not replacing physical human labor, it is replacing human thought, gut feel, and ingenuity, which is largely how this process works currently. HOWEVER, at least

INDUSTRY 4.0

EPISODE 8 Part 2

from my perspective, there still seems to be a lot of questions for exactly how to make this process and application function well. As I said in the last episode, I am not a molder. I look at the range of different molds, and the laundry list of details about each mold, and frankly speaking, walk myself quite far into the weeds, trying to find the simple solution. I could easily define a list of 10-12 mold characteristics that may contribute to some formulation of compatibility. But, indeed, this may be going too far. Some items in that list may be of great importance, and some may be less critical to the success of this platform. The primary machinery and its related capabilities also have a significant role to play in the equation. As does your customer demands on your production capabilities, schedules, and requirements. I do not believe that it is any molders goal to have machines not being used to their maximum capabilities. Let me rephrase that with a more positive spin…every molder wants every machine to be used at its maximum production capabilities, and compatibilities. As I try to narrow this down, and work towards some level of simplification, I see the potential to use three more generalized terms: • Mold Compatibility – how molds in your facility have similar characteristics and compatible process windows so that they can run successfully with a specific list of other molds. • Machine Compatibility – which molds can run on which machines, and with which list of specific molds as listed above. • Production Compatibility – what is in your production schedule and how can you ensure maximum production efficiency.

this type of application. If equations and molding parameters can be automatically communicated, and automatically updated to the primary machinery in the event of a process or mold change, and the primary machinery makes the necessary adjustments to maximize efficiency…this is Machinery communicating with Machinery, the real intention of Industry 4.0. This could continue to be expanded with other support equipment, such as environmental monitoring, process monitoring, resin management, labor control, and potential direct communication with ERP or MRP systems for maximum long-term control and cost management. I hope that this has affirmed that there is potential for this

If the expectation is for an application to take these three categories of information and apply that to a simple A+B+C = D, then we have achieved the end game. The potential of this Industry 4.0 application comes with the next step when “D” gets communicated directly to the Primary Machinery, without human intervention, to make the necessary adjustments to maximize performance of all the moving parts. This for me is the exciting and most beneficial purpose and eventual intention of

type of platform to exist, and to be developed. I am anxious to know your thoughts, and to discuss this in detail with whoever is willing. The more knowledge that we can gain together, the better our collective minds can solve the problems, and accomplish great things! Please send your questions. I am looking forward to the next challenge. Come and see me at our booth, grab me in the hall, lets grab a beverage of choice.

ASSOCIATION OF ROTATIONAL MOULDERS AUSTRALASIA LTD • ARMA

ARMA Webinar on Use of Robotics for the Application of Mould in Graphics This webinar is an industry update on the project that ARMA has funded along with ARMCE and in conjunction with the Queens University Belfast. It forms part of a PhD project at Queen’s University on the development, simulation, and optimisation of an Advanced Robotic Manufacturing Cell for the rotational moulding process. This project aims to develop

the level of automation and technology use in the rotational moulding process and the webinar provided insight into the development of the project around using automation for the application of graphics and was presented by the QUB PhD student, Conor Moore.

ARMA Networking Events a Success With the postponement of our annual conference and the limited travel allowed within Australia and New Zealand, the decision was made to host a series of networking events in Australia and New Zealand in conjunction with the launch of the online Masterclass at the Machine video series. Starting with a breakfast in Brisbane, then a brunch in Melbourne, and a luncheon in Auckland, over 85 attendees took the time to get together, for the first time in 2 years. Based around the opportunity to network in a casual environment, there were presentations from Masterclass Sponsors, PSI Brand, Qenos, Matrix Polymers & Micropellets Australia as well as insight into where ARMA is heading over the next 2 years. The first of the Masterclass at the Machine technical video series was then played as everyone enjoyed their meal and took the time to catch up.

The feedback was extremely positive and smaller, localised events will be organised over the next 12 months, as we strive to open up and hopefully be able to conference again in 2022

Safety Takes Priority for ARMA The Safety Working Group started coming together at the beginning of this year, kicking off with a review of the Large Product Delivery Guide. This guide outlines the responsibilities that relate to the loading and unloading of large products and is designed to help support the respective safety journey of our members and supporters. They are now reviewing the ARMA

NEWS 100% of ARMA Members & Supporters to be Pledge Zero Pellet Loss by 2023 The Environment Group have set some big goals this year and one of them is that all our members and supporters have been through the Operation Clean Sweep audit process and have pledged their commitment. It’s one way that our industry can do their part in ensuring the best environment and water ways for the future. It an easy process within our partnership with Operation Clean Sweep. The Plastics Industry Association introduced the Operation Clean Sweep® program to the USA in 1992. Since then, it has also been successfully implemented in over 22 jurisdictions including Europe, New Zealand, and Canada. The message is simple: Resin pellets should be contained, reclaimed, and/or disposed of properly. The program has now been introduced to Australia and is funded through the Victorian Government’s Litter Hotspots Program. Operation Clean Sweep® aligns with the United Nations Sustainable Development Goals. The Sustainable Development Goals are a call for action by all countries – poor, rich, and middle-income – to promote prosperity while protecting the planet. They recognise that ending poverty must go together with strategies that build economic growth and address a range

of social needs including education, health, social protection, and job opportunities, while tackling climate change and environmental protection. Specifically, Operation Clean Sweep® links to the following Sustainable Development Goals: • • • • •

Industry, Innovation & Infrastructure Sustainable Cities & Communities Responsible Consumption & Production Life Below Water Partnerships For The Goals

The program with its self-audit process is being promoted through the membership and assisted audits are currently offered in New Zealand and will soon be available in Australia too.

ARMA Working With RHA Around Changes To Water Tank Legislation ARMA believes that working partnerships with other associations support our industry in a beneficial way and our relationship with Rainwater Harvesting Australia and its industry groups is one way we are developing this. Currently the NSW Government is considering recommendations to remove the rainwater harvesting requirement from BASIX (Building Sustainability Index), which has a major impact on the industry in NSW, but also lays a foundation that could spread throughout Australia. BASIX was introduced in 2004 to ensure new homes and major renovations were sustainable and we were protecting our water and energy resources. “One of the key findings of the original BASIX research was that builders don’t receive any benefit from installing water efficient equipment, which would result in lower water bills as well as reducing the need for expensive infrastructure for water efficiency. As a result, builders are generally opposed to BASIX as it adds to their time and costs. The water industry would also much prefer customers to use utility water rather than rainwater as they are in the business of building and maintaining water infrastructure. This situation is a clear demonstration of ‘market failure’ and explains why the economically efficient BASIX was a critical

intervention by government. Another serious problem is the combination of more buildings and road coverings. This combined with the heavier predicted rainfall in our cities will increase localised ‘flash’ flooding damaging our precious natural waterways. It should be noted that since BASIX was introduced, rainwater harvesting has been recognised as an important engineering solution for stormwater management and will be increasingly important in the future as stormwater runoff increases with further urban and regional development. In the next drought we will find that the water infrastructure we invested in so heavily is now insufficient to meet demand as the water from our rooves goes down the gutter to cause flooding and increase insurance premiums. Today’s politicians have largely forgotten the lessons of the Millennium drought.” (published on the RHA website, https://rainwaterharvesting.org.au/ from article “Basix must be retained to secure or water future, August 5th.) ARMA is working alongside RHA and other organisations to collate a response from the rainwater industry to local government as well as the decision makers around this legislative change. www.rotoworldmag.com 57

NEWS BRITISH PLASTICS FEDERATION ROTATIONAL MOULDING GROUP • BPF

BPF Launches PolymerJobs.co.uk to Promote Plastics Industry Jobs

The British Plastics Federation (BPF) has recently launched PolymerJobs.co.uk, a new website that lists available positions within the industry. The website specialises in plastics jobs, such as toolmakers, shift engineers, sales managers, project engineers, technicians, and many other roles critical to the industry. Companies are invited to submit their jobs to be posted on the site by filling out a form which asks important details about the role, a service that is initially free to BPF member firms. The plastics industry has in previous years reported that finding skilled staff is a key area of focus for many companies, with a recent BPF survey finding that 42% of plastics companies report difficulty recruiting new staff. The new website is an initiative by the BPF to help recruit skilled individuals into the industry by helping to promote the excellent range of roles and opportunities to jobseekers. Alongside the opportunity to post jobs, companies will also have the option to have their job featured and highlighted at the top of the search results page. Director General of the British Plastics Federation, Philip Law, states: 58 ROTOWORLD® AUGUST-SEPTEMBER 2021

“Led by the BPF Education and Skills Committee, this initiative is an important effort to help promote the great range of roles the plastics industry offers skilled individuals. For the industry’s continued and heathy growth, it is of course vital that individuals with key skills are matched up to the important roles that exist today. We hope that polymerjobs.co.uk can help contribute in this area, and the BPF will continue its work to help promote recruitment in the industry.” The BPF continues to work closely with its members to promote the plastics industry and more information on these efforts, such as a spotlight on different plastic careers, as well as a new polymer careers video, can be found at www.polymerzone.co.uk.

NEWS The BPF Launches Online Recycling Resource with Plastics Europe & RECOUP The British Plastics Federation (BPF), in conjunction with PlasticsEurope and RECOUP, has launched a new online recycling resource kit aimed at educating students about recycling plastics and the science of polymers. Tied to the national curriculum and featuring a simple but informative ‘sink-float’ experiment, the new resource aims to turn students into ‘recycling champions’. The resource can be found on the Times Educational Supplement (TES) website as well as on the BPF’s PolymerZone.co.uk. Teachers can use the free online kit to help students learn how the recycling system works, as well as to explore the scientific properties of different polymers. The sink-float experiment is a hands-on way of learning how recyclers correctly sort distinct types of plastic. The kit is designed for Key Stage 2 students aged between 7 and 11 years old and the materials needed for the experiments are simple to source. These can be found from milk cartons, empty bottles, and plastic bags. British Plastics Federation Director General Philip Law states: “Working closely with PlasticsEurope and RECOUP, we are very proud to launch this special plastic recycling resource for schools. Understanding recycling plastic has never been more vital. We hope educating young students about the interesting science behind collecting, sorting and reprocessing plastic waste will help

encourage positive participation in recycling and allow young people to see how their actions at home benefit the environment and make a real difference.” PlasticsEurope Resource Efficiency Senior Manager Adrian Whyle added: “We have welcomed the opportunity to be part of creating this unique plastic recycling resource for schools. Our aim is that by using this valuable resource young citizens will understand the importance of their contribution in driving up recycling rates and the associated reductions in littering. Equipped with this knowledge they too can become agents for change in helping society reach its Circular Economy objectives whilst at the same time mitigating against climate change”. Anne Hitch, Head of Citizen and Stakeholder Strategy, at RECOUP added: “These experiments are an engaging way to educating young people about plastics and challenge students to think about the material in a scientific way. This type of education is crucial if we are to recruit the innovative plastics scientists of tomorrow. I hope that the students will thoroughly enjoy taking part in this free online resource.” In addition to this free online kit, other free resources for teachers, parents, and students are available at www. polymerzone.co.uk.
