Analysis of the development of China's plastic machinery industry

China's plastic machinery industry basic national conditions

At present, there are more than 400 major plastic machinery manufacturing enterprises in China, most of which are distributed in the southeast coast, the Pearl River Delta and the Yangtze River Delta. Among them: injection molding machine manufacturing enterprises are mainly concentrated in Zhejiang, Guangdong, followed by Jiangsu, Shanghai, Guangxi and other places; extruder manufacturing enterprises are mainly distributed in Shandong, Liaoning, Jiangsu, Gansu, Henan, Beijing and other places; hollow molding machine manufacturing enterprises Mainly concentrated in Shaanxi, Shanghai, Jiangsu, Guangxi and other places; Tibet, Xinjiang, Qinghai, Ningxia, Hainan, Chongqing and other provinces and cities have not yet had plastic machinery manufacturing enterprises. At present, the plastic machinery that can be produced in China can basically meet the general technical equipment needed for the processing and molding of polymer synthetic materials. Generally speaking, it is equivalent to Hong Kong and Taiwan in China, and some of them have approached or reached the level of industrial developed countries, and some of them are leading the world.

In recent years, China's plastic machinery has become one of the fastest growing industries in the traditional machinery manufacturing industry, with an annual demand of 8.5 billion yuan. Experts predict that in the next 15 years, China's plastic machinery industry will continue to grow at a high speed.

China's plastic machinery industry's "Twelfth Five-Year" development plan will focus on six major areas of precision casting equipment, energy-saving plastic molding processing equipment. By 2015, China's plastic machinery industry will master a number of core technologies with independent intellectual property rights, upgrade a number of industrial clusters with distinctive and well-known brands, and realize the transformation of the plastic machinery industry from large to strong.

Plastic machine equipment has penetrated all walks of life

Building materials industry: In this industry sector, the plastic machinery industry is mainly used for the production and supply of pipes, water pipes, various decoration materials, flooring, doors and windows, materials, waterproofing coils, trunking, and line pipe.

Packaging industry: The plastic machinery industry mainly provides equipment for the production of various packaging films, sheets, bottles, cylinders, boxes, barrels, boxes, woven bags, turnover boxes, trays and other plastic packaging products. Such plastic packaging products involve a wide variety of industries, such as beverages, food, chemicals, cement, feed, aquatic products, fruits, hardware tools, clothing, pharmaceuticals and other industries that produce almost all products.

Electrical and electronic information industry: refrigerators, washing machines, air conditioners, video cameras, recorders, televisions, small appliances, computers, printers, fax machines, mobile phones, telephones, etc., casings, accessories, transmission lines and sockets, etc. Production of various types of optical discs (CD, VCD, DVD, CD-RW, DVD-R, DVD-RW, HDVD) for the production of information carriers are provided by the plastic machinery industry.

Automobiles and other transportation (trains, ships, airplanes, spaceships) Industry: automobile insurance equipment, instrument panels, special electrical appliances (audio, air conditioning), covering parts, interior trim parts, heat and pressure resistant oil resistant pipes, fuel tanks, seals The production of strips, trunks, seats, fabrics, door sills, dust slabs, airbag coverings, car floor liners, etc. are all required to be supplied by the plastics machinery industry.

Agriculture: The production of greenhouses, double-deck roofs, irrigation and drainage pipeline systems, seedling membranes, light-transmissive or shading membranes, and fertilizer-preserving membranes are required to be supplied by the plastics machinery industry.

In addition to the above, there are many departments that require plastic machinery industry to provide equipment, such as daily necessities, mechanical parts, toys, game consoles, sporting goods, medical equipment, furniture and other industries.

Overall level to be improved

Some domestic plastic machinery enterprises have seized the good opportunity in recent years and achieved leap-forward development. They not only occupy a large domestic market share, but also a considerable number of products are exported to foreign countries. However, the export products are mainly exported to developing countries. , is a medium and low-end products. As far as the overall technical level is concerned, the gap between China's plastic machinery and developed countries is more than 20 years. In recent years, the imported plastic machine equipment mainly includes: precision injection molding machine, one-step injection blow molding unit, large diameter solid wall tube and bellows production line, geomembrane production line, biaxial stretch film production line, drip irrigation pipe production line, medical catheter production line, Audio-video base and photosensitive base production line, twin-screw mixing and granulating equipment, in which large-scale twin-screw extrusion granulation equipment for petrochemical is basically completely dependent on imports. This has resulted in the sales of more than 20 foreign plastic machinery enterprises in China equal to the total sales of thousands of domestic plastic machine enterprises.

Large mechanical performance gap

Compared with foreign products, the performance of China's plastic machinery has a large gap in the injection molding, extrusion speed, precision of injection molding products and control level of processing equipment. The filling speed of injection molding machines of foreign companies can reach 500~1000m/s, the output of blow molding 250ml beverage bottles can reach ~1/hour, and the maximum output of domestic equipment is 6000~8000/hour; domestic extruder The average output of the mainframe is less than 60% of the foreign advanced level. Japan's Nissei company produces 20-360 tons of ES series electric injection molding machine, the quality deviation of molded products can be controlled within 0.00132g grams, the displacement control accuracy of the clamping mechanism can reach 0.03mm, temperature control accuracy can reach ±0.5 °C.

The level of plastic processing equipment depends to a large extent on the level of measurement and control. The control system of foreign advanced plastic machinery generally adopts programmable system with PC, PLC, PCC as the core, and adopts fuzzy control, statistical process control (SPC) and remote monitoring based on network in some high-precision production equipment. , troubleshooting and control systems. China's advanced measurement systems rely on imports.

Technological innovation promotes development

The per capita consumption of plastic products in China is only 14kg/year, ranking 70th in the world, so in the future, the demand for plastic products and plastic machinery will maintain a high growth rate, which will give China Plastic machinery companies provide a good opportunity for development.

At the same time, foreign plastic machinery companies are targeting China's highly promising market. They have provided a large number of plastic machinery for China's plastic products factory, and tried to occupy a higher market share to reduce the harmfulness of snow melting agents. However, domestic plastic machinery enterprises have invested little in technological innovation, mainly to imitate the way of domestic and foreign counterpart products, and rarely have independent intellectual property rights products. This has caused the domestic plastic machinery products to lag behind foreign countries for a long time, and the domestic products are similar. There are few specialized research institutions for plastic machinery in China, and there is a serious shortage of research and innovation funds.

With China's entry into the WTO, China's knowledge and technology property rights continue to improve, increase investment in scientific and technological innovation, attract professional and technical personnel, achieve large-scale and specialized production, and strive to shorten the huge gap in the level of plastic machinery technology at home and abroad. It has become the consensus of people of insight in the field of plastic machinery.
