The production of plastic raw materials and plastic products cannot be separated from plastic machinery. With the rapid development of China's plastics industry, plastic machinery has become one of the fastest growing industries in the machinery industry. In recent years, the growth rate has been about 30%. The annual manufacturing capacity has reached about 200,000 sets (sets), ranking first in the world. The output accounts for 25% of the world's total output, but the output value only accounts for 9% of the world total output value. China's plastic machinery still has a market gap of 10 billion yuan each year, and 60% of high-end plastic machinery products need to be imported. So far, the plastic granulation units in China's large-scale ethylene projects, the precision injection molding machines needed in electronics and communication engineering, the large-scale injection molding machines and large-scale multi-layer blow molding machines needed in the automotive industry, are used in large quantities in the packaging industry. The biaxially stretched film production equipment, multi-layer blow molding machines, and precision extruders required in the medical and health field basically rely on imports.
The majority of domestic plastic machinery is still low-end products, can not meet the need to produce high-end plastic products, mainly due to the lack of technology with independent intellectual property rights, the lack of "Chinese core." There is a saying in the press industry that if we remove the imported key components and core technologies, only a pile of steel will remain.
"If workers want to do good things, they must first sharpen their tools." The domestic plastic machinery technology content is not high, the product is of low grade, lack of core technology, which restricts the upgrading of China's plastics industry. As the relevant experts pointed out, the market for plastics machinery is mainly in the field of plastics processing, and a considerable part of the domestic product companies only produce basic daily-use plastic products and simple industrial supplies, and lack the ability to use high-tech presses to improve product quality. Only satisfied with general processing equipment. There is no demand for product companies, and it is difficult for the press makers' technological innovation to obtain market response. The innovation ability of R&D core technology of presses companies will naturally be greatly inhibited.
In general, the core technology of press manufacturing is to provide the most reasonable technological conditions and process routes for plastic products. The innovation of plastic presses is inseparable from the formulation and process conditions of plastic raw materials, but due to historical reasons, from the industrial management to the manufacture of machinery and products, it is in a serious state of separation. Mechanical manufacturing companies emphasize the introduction of mechanical and electrical talents and the improvement of mechanical processing conditions, ignoring the research on plastics processing technology. Without accurately grasping the characteristics of different raw materials and their processing conditions, there is no technological innovation in plastics machinery manufacturing.
The development of the core technologies of domestic plastics machinery and the improvement of its technological level require the joint efforts of all parties. Plastics raw materials and products manufacturing enterprises can not only be satisfied with the production of some low-end products, whether it is from the community or from the company's own needs, to improve product quality is a must. As a press company, it should be closely integrated with plastic production, increase technical investment, and develop new technologies and new products, such as the development of sophisticated large-scale injection molding machines, composites, and large-scale hollow molding machines. At the same time, we must do a good job in the application of microelectronics technology in plastics machinery, and gradually realize the computer control of injection molding, extrusion, hollowing, calendering, and other basic molding processing machine mainframes and subsequent equipment programs to improve the control level of plastics machinery. These high-end products and control technologies all require breakthroughs in core technologies and are the only way for the development of China's press industry.
