2016-11-21  505

Plastic machinery industry is a machinery manufacturing industry that provides important technical equipment for plastic raw material industry and plastic product processing industry. China's plastic machinery began in the late 1950s. In 1958, China's first injection molding machine was born in Shanghai, opening a new page in China's own manufacturing of plastic machinery. However, the technology content of the injection molding machine produced at that time was low, and only general plastics could be used to produce daily necessities with low technical requirements, such as plastic boxes, plastic barrels, plastic basins, etc. With the development of China's petrochemical industry, China's plastic machinery industry has gradually formed an independent industrial department and begun to take shape. It is an important part of the national machinery industry. Especially since the reform and opening up, China's plastic machinery industry has made great progress.

Basic national conditions of China's Plastic Machinery Industry

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 and 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 forming machine manufacturing enterprises are mainly concentrated in Shaanxi, Shanghai, Jiangsu, Guangxi and other places; So far, there are no plastic machinery manufacturing enterprises in Tibet, Xinjiang, Qinghai, Ningxia, Hainan, Chongqing and other provinces and cities. Among all 194 machinery industries in China, the main economic indicators of the plastic machinery industry rank in the forefront. At present, the plastic machinery that can be produced in China can basically meet the general technical equipment required for the processing and molding of polymer synthetic materials. On the whole, it is equivalent to Hong Kong and Taiwan. Some have approached or reached the level of industrial developed countries, and some are leading in the world.

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

Historical statistics show that the growth in the output of plastic products has led to the growth in the sales of plastic machinery. For example, from 1991 to 1999, the average annual output of plastic products increased by 26.61%, and the sales of plastic machinery increased by 17.38% in the same period. The long-term plan of China's plastic industry is that the output of plastic products will reach 25 million tons by 2005, and the total output is expected to double to 50 million tons in 2015. The good development prospect of plastic processing industry will still be the main driving force for the rapid development of China's plastic machinery industry.

The 12th Five year development plan of China's plastic machinery industry will focus on six areas, such as precision casting equipment and energy-saving plastic molding and processing equipment. By 2015, China's plastic machinery industry will master a number of core technologies with independent intellectual property rights, improve a number of industrial clusters with characteristics and well-known brands, and realize the transformation of the plastic machinery industry from big 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 to provide equipment for the production of sewer pipes, water supply pipes, various decoration materials, floors, carpets, different materials for doors and windows, waterproof coiled materials, trunking, conduit, etc.

Packaging industry: the plastic machinery industry mainly provides equipment for the production of plastic packaging products such as various packaging films, sheets, bottles, cylinders, boxes, barrels, boxes, woven bags, mesh sets, turnover boxes, pallets, etc. This kind of plastic packaging products involves a wide range of industries, such as beverage, food, chemical industry, cement, feed, aquatic products, fruits, hardware tools, clothing, instruments, pharmaceuticals and other industries producing almost all products.

Electrical and electronic information industry: production of enclosures, components, transmission lines and sockets of refrigerators, washing machines, air conditioners, video recorders, tape recorders, televisions, stereos, small appliances, computers, printers, fax machines, mobile phones, telephones, etc., and various optical discs (CD, VCD, DVD, CD-R, CD-RW, DVD-R, DVD-RW, hddd) of information carriers Our production is equipped by the plastic machinery industry.

Automobile and other transportation (train, ship, aircraft, spacecraft) industries: automobile safety equipment, instrument panel, special electrical appliances (audio, air conditioning), covering parts, interior decoration parts, heat and pressure resistant oil pipe, fuel tank, sealing strip, trunk, seat, paving materials, door panel, dust plate, airbag covering glue The production of car bottom liner... Needs the production equipment provided by the plastic machinery industry.

Agriculture: the production of greenhouse, double-layer shed roof, drainage and irrigation pipeline system, seedling film, transparent or shading film, fertilizer and medicine protection film, etc. requires the equipment provided by the plastic machinery industry.

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

The overall level needs to be improved

Some domestic plastic machinery enterprises have seized the great opportunity in recent years and achieved leapfrog development. They not only occupy a large domestic market share, but also export a considerable number of products abroad. However, the export products are mainly sold to developing countries, which are medium and low-grade products. In terms of the overall technical level, the gap between China's plastic machinery and foreign developed countries is more than 20 years. In recent years, the imported plastic machines and equipment mainly include: precision injection molding machine, one-step injection, drawing and blowing unit, large-diameter solid wall pipe and bellows production line, geomembrane production line, biaxial tensile film production line, drip irrigation pipe production line, medical catheter production line, audio-visual film base and photosensitive film base production line, twin-screw mixing and granulation equipment, Among them, the large-scale twin-screw extrusion granulation equipment for petrochemical industry basically depends on imports. This has resulted in the situation that the sales of more than 20 foreign plastic machinery enterprises in China are equal to the total sales of thousands of domestic plastic machinery enterprises.

Large gap in mechanical properties

Compared with foreign products, there is a big gap in the performance of plastic machinery in China in terms of injection molding, extrusion molding 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 single machine output of blow molding 250ml beverage bottles can generally reach ~ per hour, while the maximum output of domestic equipment is 6000 ~ 8000 per hour; The average output of single extruder in China is less than 60% of the foreign advanced level. The ES series electric injection molding machine with mold locking force of 20 ~ 360 tons produced by Nissei company in Japan can control the quality deviation of molded products within 0.00132g g g, the displacement control accuracy of clamping mechanism can reach 0.03mm, and the temperature control accuracy can reach ± 0.5 ℃.

The level of plastic processing equipment largely depends on the level of measurement and control. The control system of foreign advanced plastic machinery generally adopts the programmable system with PC, PLC and PCC as the core, and adopts fuzzy control, statistical process control (SPC), and network-based remote monitoring, fault diagnosis and control system in some high-precision production equipment. In terms of advanced measurement systems, China basically depends on imports.

Technological innovation promotes development

The per capita consumption of plastic products in China is only 14kg / year, ranking behind the 70th in the world. Therefore, the demand for plastic products and plastic machinery will maintain a high growth rate for a long time in the future. This provides a good development opportunity for China's plastic machinery enterprises. At the same time, foreign plastic machinery enterprises are aiming at China, a large potential market. They have provided a large number of plastic machinery for China's plastic products factories and tried to occupy a higher market share and take measures to reduce the harm of snow melting agent. However, domestic plastic machinery enterprises have little investment in technological innovation, mainly by imitating the products of their peers at home and abroad, and there are few products with independent intellectual property rights. This leads to the situation that domestic plastic machinery products lag behind foreign countries for a long time and domestic products are the same. At the same time, there are few specialized research institutions of plastic machinery in China, and there is a serious shortage of scientific research and innovation funds. With China's entry into WTO, China has continuously improved its intellectual and technological property rights. It has become the consensus of people of insight in the field of plastic machinery to increase investment in scientific and technological innovation, attract professional and technical talents, realize large-scale and professional production, and strive to shorten the huge gap in the technical level of plastic machinery at home and abroad.
