Plastic machinery industry Is to provide important technical equipment of the mechanical manufacturing industry for plastic raw materials industry, plastic products processing industry. Plastic machinery of our country began in the late fifty's, 1958 China's first injection molding machine was born in Shanghai, opened our own manufacturing a new page of plastic machinery. But the content of the injection molding machine technology when the production is low, commodity can only use general plastics to produce low technical requirements, such as plastic boxes, plastic barrels, plastic pots etc.. With the development of petrochemical industry in China, China's plastics machinery industry has gradually formed an independent industrial sector, and a certain scale, is an important part of the national machinery industry, especially since the reform and opening up, China's plastics machinery industry has been considerable development.

The basic situation of China's plastics machinery industry

At present, China's major plastic machinery manufacturing enterprises have more than 400, mostly in the southeast coast, the Pearl River Delta, Yangtze River delta. The injection molding machine manufacturing enterprises mainly concentrated in Zhejiang, Guangdong, Shanghai, followed by Jiangsu, Guangxi and other places; extrusion machine 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, Tibet, Guangxi and other places; Xinjiang, Qinghai, Ningxia, Hainan, Chongqing and other provinces and cities so far no plastic machinery manufacturing enterprises. The main economic indicators in all of the country's one hundred and ninety-four machinery industry in the plastics machinery industry are in the forefront. At present, China's plastics machinery production, has been basically able to meet the general technical equipment for processing and molding of polymer materials needed. On the whole, Hongkong and Taiwan area China, some have been close to or reached the level of developed industrial countries, the world's leading individual.

In recent years, China's plastics machinery has become one of the most rapid development of the industry of traditional mechanical manufacturing industry, the annual demand amounted to 8 billion 500 million yuan. Experts predict that the next 15 years, China's plastics machinery industry will continue rapid growth.

Historical statistics show that the increase of plastic product LED plastic machinery sales growth. As from 1991 to 1999, the production of plastic products with an annual growth rate of 26.61% over the same period, plastic machinery sales rose 17.38%. The long-term plan for China's plastics industry of plastic products in 2005 production will reach 25 million tons, in 2015 is expected to total output doubled, reaching 50 million tons. The plastics processing industry good prospects, will continue to be the main driving force for the rapid development of Chinese plastic machinery industry.

Planning Chinese plastic machinery industry will be the twelfth five year development precision casting equipment, energy-saving plastic molding processing equipment and other six areas as the focus of development. By 2015, China's plastics machinery industry will master a number of core technologies with independent intellectual property rights, enhance the number of features and well-known brands of industrial clusters, the plastic machinery industry from big to strong.

Machine equipment has penetrated all walks of life

Building materials industry: in this industry, plastics machinery industry is mainly used for water pipe, water pipe, various decoration material, flooring, carpet, doors and windows of different materials, waterproofing materials, trunking, line pipe...... Provide equipment production.

Packaging industry: plastic machinery industry is mainly composed of a variety of packaging film, sheet, bottle, box, cylinder, barrel, box, bag, nets, turnover box, tray...... Provide equipment such as plastic packaging products production. This kind of plastic packaging products involved in various categories of the industry, such as food, beverage, chemical, cement, feed, aquatic products, fruit, clothing, hardware tools, instruments, pharmaceutical and other production sectors almost all products.

Electrical appliances, electronic information industry: refrigerator, washing machine, air conditioner, video cameras, tape recorders, TV, stereo, small appliances, computer, printer, fax machine, telephone, mobile phone...... Chassis, product components, transmission line and sockets production, all kinds of information carriers (CD, VCD, DVD, CD, CD-R, CD-RW, DVD-R, DVD-RW, HDVD) production by the plastics machinery industry to provide equipment.

Car and other traffic (train, ship, aircraft, spacecraft) industry: Automobile Insurance machinery, instrument panel, electric appliance (audio, air conditioning), drape, interior decoration, heat pressure hose, fuel tank, sealing strip, suitcase, seat, car door, Chen PU wood plate, the dust the airbag cover plate, and the carriage bottom liner...... The production of plastic machinery industry are required to provide equipment for the production.

Agriculture: greenhouse, double roof, irrigation and drainage pipeline system, seedling film, transparent or light shielding film, protecting fertilizer membrane...... The production of plastic machinery industry to provide equipment.

In addition to the above, there are still many departments are required to provide the equipment of plastic machinery industry, such as daily necessities, mechanical parts, toys, games, sports, medical appliances, furniture and other industries.

The overall level to be improved

Some of the domestic plastic machinery enterprises to seize the opportunity in recent years, to achieve leapfrog development, not only occupy a larger domestic market share, there are a considerable number of products exported to foreign countries, however, export products are mainly exported to developing countries, is in the low-end products. The overall technical level of China's plastics machinery, the gap between home and abroad in more than 20 years. In recent years, dependence on imports of machinery equipment are: precision injection molding machine, one-step injection stretch blow unit, large diameter solid wall pipe and corrugated pipe production line, geomembrane production line, two-way stretch film production line, drip irrigation pipe production line, production line, medical catheter based film and photographic film audio and video production line, double screw mixing granulating equipment, including large petrochemical double screw extruder equipment basically is completely dependent on imports. This has resulted in more than 20 foreign plastic machinery enterprises amounted to thousands of domestic plastic enterprise sales situation in the domestic sales sum.

The mechanical properties of gap

Compared with foreign products, the level of control performance of China's plastics machinery extrusion precision forming speed, injection molding and processing equipment in injection molding, which are a large gap. The foreign company of injection molding machine filling speed can reach 500 ~ 1000m/s, ~ 250ml generally reach the yield of single blow beverage bottles per hour, and the highest yield of domestic equipment is 6000 ~ 8000 / hour; domestic extruder mainframe single output on average less than 60% of the foreign advanced level. Nissei company of Japan, the clamping force of 20 to 360 tons of ES series of electric injection molding machine, molding quality deviation can be controlled at 0.00132g grams or less, the control precision of the displacement of up to 0.03mm of the locking mechanism, the temperature control precision is up to 0.5 DEG C.

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

The development of technology innovation

China's per capita consumption of plastic products is only 14kg/ years, is ranked 70 in the world, so in a very long time in the future, plastic products and plastic machinery demand will maintain a high growth rate. Provides a good opportunity for the development of plastic machinery enterprises in china. At the same time, plastic machinery enterprises abroad is aimed at China this potential big market, they have provided for China plastic products factory large plastic machinery, and try to occupy a higher market share to reduce the harm of deicing measures. While the domestic plastic machinery enterprises invested in technological innovation rarely, mainly go way of imitation products at home and abroad counterparts, have independent intellectual property products. This caused the domestic plastics machinery products long lags behind abroad, domestic situation of similar products. At the same time, the domestic plastics machinery specialized research institutions, generally there is a serious shortage of scientific research and innovation funding problems. With China's entry into WTO, domestic continuous improvement in knowledge and technology property, increase scientific and technological innovation investment, to attract professional and technical personnel, to achieve the scale and specialization of production, to shorten the gap between domestic and international level plastic machinery technology, has become the consensus of the field of plastic machine is a person with breadth of vision.
