The lack of independent research and development o

The lack of independent research and development of core technologies in the plastic machinery industry is the key.

at present, the overall technical level of the main products of China's plastic machinery is equivalent to that of the international technologically advanced countries in the early 1980s, some products reached the level of the middle and late 1980s, and a few products are close to the level of the 1990s. Not only that, the typical performance of China's plastic machinery industry is that there is no core technology

"plastic machinery provides processing equipment for plastic products. It is also the field that can best reflect the core technology value in the whole plastic industry. But in this field, we hardly have important core technology." Wang Xingtian, a professor at Beijing University of chemical technology, said

Wang Xingtian pointed out that at present, Zhao Ping, director of the International Trade Research Department of the Research Institute of the China Council for the promotion of international trade, said that the gap between China's plastic machinery industry and foreign countries in terms of high-end models is still very obvious, especially in terms of precision machinery. Compared with industrial developed countries, such as Germany, Japan, Italy and other countries, there is a big gap, mainly manifested in fewer varieties, high energy consumption, low control level, unstable performance and so on. For example, the development of the electronic information industry puts forward high requirements for the refinement of plastic parts. The control accuracy and product repetition accuracy of domestic plastic machines are more than half lower than the world's advanced level. 60% of the plastic machines imported by China every year are precision injection molding machine equipment. In addition, the energy consumption level of plastic machinery in China is more than twice that of foreign advanced level; The measurement and control technology is 10 ~ 15 years behind foreign countries; The service life is half lower than that of foreign countries; The noise needs to speed up the basic processing technology of ultra-high molecular weight polyethylene, the implementation and utilization of CO2 supercritical foaming process, and the promotion of electromagnetic induction energy-saving technology, so as to break the foreign monopoly and replace the import as the target line. The average level is more than 10 dB higher than that of foreign countries

in order to make China's plastic machinery level in line with the world as soon as possible, it is not enough to simply rely on the introduction of foreign technology for effective installation. We must start with the independent research and development of cutting-edge technology, change the backward situation of China's plastic machinery level, and enhance our competitiveness in the international market

to develop the core technology of domestic plastic machinery and improve its technical level requires the joint efforts of all parties. Plastic raw materials and products manufacturing enterprises can not only be satisfied with a small fortune, but can live on the line. At present, the industry lacks precision large-scale injection molding machines, composite and large-scale hollow molding machines, and the application and development of microelectronics technology in plastic machinery. These high-end products and control technologies need breakthroughs in core technologies

therefore, if conditions permit, we should continue to learn from foreign advanced products, processes and equipment to develop China's plastic machinery and improve the technical level through various ways, including joint ventures and cooperation. This will not only help to improve the overall level of the industry, but also help the whole industry to develop in the direction of social specialization and cooperation, and improve its international competitiveness
