The digital and circular economy is one of the themes of the K 2022 exhibition. Prior to the K2022 exhibition, the German Machinery Equipment and Manufacturers Association (VDMA) interviewed the chief executive officer of the resident Demag, GED LIEBIG. GERD LIEBIG stated in an interview that due to the low energy consumption of the entire motor, the prospects of the full power injection molding machine can be expected. 1644807834811364.jpg Sumitter Demag Global CEO GERD LIEBIGVDMA: Sumitomo Dema is part of the Japanese Sumitomo Group. Japan has been a circular economy legislation since 2000. What level of the current circular economy of Japan is at present? GERD LIEBIG: The fundamental difference between Japan and Germany is that Japan is an island country -therefore, everything is independent supervision, including incentive measures, waste classification and recycling. Japan also relies on consumers’ high self -discipline to promote the circular economy. For Japan, marine and fisheries are very important, and people are more sensitive to marine pollution. Therefore, the support of the Japanese people’s circular economy is higher than many European countries. In Europe, people pay attention to the ban, but they don’t know that without using plastic will actually increase carbon footprints. For example, it is difficult to separate the coating layer from the paper layer as a height of composite materials, which is not a feasible choice for a replacement plastic. The same is true of glass, whether in production or long -distance transportation, it consumes more energy than plastic. VDMA: How about Sustainty Development, Sumaton (SHI) Demag and his parent company cooperate with your parent company? GERD LIEBIG: The climate is neutral and played a key role in the Sumitomo Group, and the CEO of all affiliated companies must work hard to achieve sustainable development and neutral climate. The most important way to achieve this goal is that we focus on full electric machines, thereby significantly reduced carbon dioxide emissions. Ten years ago, only 20% of the machines were all electric, and now the full -power injection molding machine has accounted for 80% of the total amount of Demagstine injection machines. VDMA: Is there any other trend worth paying attention? GERD LIEBIG: Yes, due to sustainability and climate neutrality, it also involves the consumer field. I expect the demand for full electric machines to increase in this field. Five years ago, we transformed a factory in Germany into a production base for all electric injection machines. Although it was difficult to promote this change at that time -after all, it had to give up 20% of the order volume at that time, but it seems that the decision at the time was very far -sighted at the time. Our expectations for the market to stealth sustainable development and energy conservation have proven to be correct. Thanks to this early decision, we now have a huge competitive advantage. VDMA: Does the new crown epidemic make the public more aware of the benefits of plastic? GERD LIEBIG: No, at least this happened in Europe. existIn China, when people use plastic, it is mainly known to bring hygiene protection to items. However, a positive signal also appeared in Europe. For example, McDonald’s decided to replace the common packaging of one -sex cardboard to durable plastic packaging in some pilot restaurants’ depository \”deposit return system\”. If consumers change their behavior and prepare more money, then this will help plastic to achieve significant success in reuse -whether in the deposit return system or recycling. VDMA: The price of polymers has risen in the past year, which has also increased the cost of plastic parts. Can it reduce the use of raw materials by processing technology? GERD LIEBIG: We encourage innovation of various materials or processes, such as foaming technology to reduce the number of materials required and help customers produce thin -walled parts with quality compliance. VDMA: What is the current use of compost and recyclable materials? GERD LIEBIG: Basically, processors need economic incentives to use such materials. Regardless of the use of regenerative materials or degradable materials, the key is how to make the quality of the product comparable to the original material. Recycling process itself is not an unpredictable technical challenge. At present, our injection molding machine can process a variety of materials, and the category of recycling materials has also been further expanded. The challenges facing these materials are mainly to regulate uneven material characteristics through intelligent process monitoring. It is rejoicing that material manufacturers are working hard to improve material performance, which makes the application of recycling materials or degradable materials full of expectations. The use limit of recycling depends mainly on the purity of the material. VDMA: What contributions can your company make to improve the sustainable development of machinery? GERD LIEBIG: Freshly focused on full electric. In Europe, one of almost every two injection plastic machines is full of electric. The whole motor is the general trend. With their success in the field of medicine and electronics, the share of the entire motor in the packaging field is increasing, and now the entire motor is increasingly applied to the automotive field. There are fewer energy, water, lubricating oil and materials consumed by all electric injection machines, which means that it has less energy consumption. Taking a 350 -ton full motor as an example: Compared with the same lock -level hydraulic machine, the carbon dioxide generated by the entire motor a year of carbon dioxide is reduced by 40% to 80% each year.
