China's plastic machinery urgently needs to improve core technology

At present, the gap between China's plastics machinery industry and foreign countries in high-end models is still very obvious, especially in precision machinery. Compared with industrialized countries such as Germany, Japan, and Italy, there is a big gap between them. High consumption, low control level, and unstable performance. The development of the electronic information industry places extremely high demands on the refinement of plastic parts. The control accuracy and the level of repeatability of products made by domestic presses are more than half lower than the world’s advanced level. 60% of the presses imported from China each year are Precision injection molding machine equipment. In addition, the energy consumption level of China's plastic machinery is more than double the advanced level in foreign countries; the measurement and control technology is 10 to 15 years behind the foreign countries; the service life is half lower than that in foreign countries; the average noise level is more than 10 dB higher than that of foreign countries. .

It is impracticable to rely solely on the introduction of foreign technologies to bring our country's presses standards into line with the world as quickly as possible. We must start from the independent research and development of cutting-edge technologies to change the backwardness of China's plastics machinery and enhance its competitiveness in the international market.

The development of the core technologies of domestic plastics machinery and the improvement of its technological level require the joint efforts of all parties. The industry lacks sophisticated large-scale injection molding machines, composite and large-scale hollow molding machines, and lacks the development of microelectronics technology in plastics machinery. These high-end products and control technologies all require breakthroughs in core technologies. Therefore, domestic plastics machinery enterprises can continue to learn from foreign advanced products and processes and equipment through various methods, including joint ventures and cooperation, to develop our country's presses and improve the technological level. This will not only help improve the overall level of the industry, but also help the industry to develop in the direction of social specialization and enhance international competitiveness.
