For cars, reducing their weight has important implications for fuel economy. According to statistics, the quality of the car itself is reduced by 10%, and fuel consumption can be reduced by 6% to 8%. With today's high oil prices, major automakers are pursuing the reduction of the weight of automobiles, and they are also pushing for the constant innovation of engineering plastics. Engineering plastics have superior mechanical properties, electrical properties and dimensional stability than ordinary plastics. Modified, special engineering plastics have excellent chemical resistance, heat resistance, abrasion resistance, weather resistance, etc. Some physicochemical properties even exceed metal materials, but the quality is lighter than metal, not only easy to shape and energy consumption during processing Small, can greatly reduce the weight of the car.
Jin Guozhen, honorary chairman of the China Engineering Plastics Industry Association, believes that automobiles are an important platform for promoting the development of engineering plastics technology. The association’s secretary-general Zheng Wei believes that the automotive industry is the largest potential market for engineering plastics and plays an important role in improving the overall technology level of the engineering plastics industry.
According to Tian Yamei, general manager of China Auto Parts Industry (Group) Co., Ltd., the development of the automotive industry has expanded the variety and application of automotive plastics, but at present there is a big gap between China's automotive engineering plastics and developed countries. At present, China's economy cars have 50 to 60 kilograms of plastic for each vehicle, and 80 kilograms for heavy trucks, far behind the average amount of 300 kilograms per vehicle in developed countries and accounting for 20% of the total vehicle quality. The amount of plastic used in China's mid- and high-class cars has only reached the level of the developed countries in the 1990s, and each vehicle is 100-130 kg. With the development trend of lightweight vehicles, it is expected that by 2030, the average amount of plastic used by each vehicle in developed countries will reach 500 kg or more. It can be seen that the application prospect of engineering plastics in the automotive industry is very broad.
Jin Guozhen also believes that at present, the application of engineering plastics in the automotive industry is still not satisfactory. China's automotive engineering plastics are mainly due to the late start, the lack of special resin brands and the backward production process, and they mainly rely on imports. At the same time, automotive plastic parts companies are small in scale and lack unified automotive plastic parts specifications and standards; corporate production, testing and testing equipment are not perfect, and cannot guarantee and accurately reflect the final performance of products; the application of computer-aided design and manufacturing technology The gap between foreign advanced industries is very large; the awareness and the degree of environmental protection of companies are not enough, and there is a lack of consideration of the research on material recycling and recycling.
Zheng Zheng believes that the reason that domestic engineering plastics are difficult to apply to the automotive industry is mainly due to the lack of adequate communication and cooperation between upstream and downstream. In addition to the lack of technical standards for auto parts in China, and the procurement or production of parts and components by automakers with corporate standards, it is difficult for engineering plastics companies to enter the automotive market. The neglect of the application of materials by engineering plastics companies is also one of the important reasons. Most foreign companies are tailor-made for automotive users in advance. In the initial stage of component design, material suppliers begin to intervene until the products are produced. However, domestic companies rarely do this.
Zheng Hao said that at present, the automotive industry to strengthen recycling is a good opportunity for engineering plastics companies to enter the field. The State has formulated the "Recycling and Utilization Technology Policy for Automobile Products". If the problem of waste utilization cannot be solved, according to this policy, car manufacturers will be eliminated. Therefore, how to cooperate with and help OEMs to unify materials, serialize work research, and formulate relevant technical standards is a good opportunity for the engineering plastics industry to communicate with automotive manufacturers. Engineering plastics companies must use this opportunity to lay the foundation for interactive development.
Tian Yamei also said that from the perspective of product development trends, automotive plastic parts show a trend of modular supply, specialized production, higher technological content, and environmentally friendly products. Zheng Zheng said that domestic engineering plastics enterprises should seize the opportunity of the development of the global automotive market, keep up with the trend of lightweight cars, and achieve an overall improvement of the industry.
Engineering plastics help the automotive industry to save energy and reduce emissions
In response to the current rapid rise in international oil prices, China's gasoline (trails) price has risen by 1,000 yuan per ton since June 20. As the main user of gasoline (chai diesel oil), the energy conservation and emission reduction of the automotive industry has once again received attention from people. The continuous innovation of engineering plastics can make outstanding contributions to the energy conservation and emission reduction of the automotive industry.
