Plastic drum manufacturers market overall level of improvement
Some domestic plastics machinery enterprises caught a good time in recent years, to achieve leapfrog development, not only occupy a larger domestic market share, there are a number of products are exported to foreign countries, however, the export products are mainly sold to developing countries, medium and low-grade products. In terms of overall technical level, the gap between China's plastic machinery and foreign developed countries is over 20 years. In recent years, imports of plastic machinery equipment mainly include: precision injection molding machine, one-step injection blowing unit, large diameter solid wall tube and corrugated pipe production line, geomembrane production line, production line for two-way stretch film, drip irrigation pipe line, medical catheter line, audio and video and photographic plates based production line and twin-screw mixing granulation equipment, including petrochemical with large twin-screw extrusion granulation equipment basically rely on imports. This has resulted in the sales of more than 20 plastic machinery enterprises in the country equal to the total sales of thousands of molding machines in China.
The mechanical performance gap is large
Compared with foreign products, the performance of plastic machinery in China has a large gap in the quality of injection molding, extrusion molding speed, precision of injection molding products and control of processing equipment. The injection molding machine of foreign companies can reach 500 ~ 1000m/s, and the single machine of the 250ml beverage bottle can reach an average of ~ an hour, while the maximum output of domestic equipment is 6000 ~ 8000 / hour. The average output of domestic extruders is less than 60% of the foreign advanced level. Japan Nissei company production of clamping force for 20 ~ 360 tons of ES series electric injection molding machine, molding products quality deviation can control within 0.00132 g g, clamping mechanism of displacement control precision can reach 0.03 mm, temperature control precision of plus or minus 0.5 ℃.
The level of plastic processing equipment depends greatly on the level of measurement and control. Foreign advanced plastic machinery control system widely adopted with PC, PLC, PCC as the core of a programmable system, and on some high precision production equipment adopted fuzzy control and statistical process control (SPC), and based on the network remote monitoring, fault diagnosis and control system. China is basically dependent on imports for advanced measurement systems.
Technological innovation is promoting development
Plastic products in China's per capita consumption is only 14 kg/year, one of the world rankings after 70, so in the future for a long time, the demand of plastic products and plastic machinery will maintain a higher growth rate, this will give our country plastic machinery enterprises provides a good opportunity for development.
At the same time, foreign plastics machinery enterprises is aimed at the the big potential market in China, they have plastic products factory provides a number of plastic machinery in China, and tried to occupy a higher market share to reduce the dangers of snowmelt agent. However, domestic plastic machinery enterprises invest very little in technological innovation, mainly making imitation of the products of domestic and foreign counterparts, with few products of independent intellectual property rights. This causes the domestic plastic machinery product to lag in the long time abroad, domestic product similar situation. There are few specialized research institutes of plastic machinery in China, and there is a serious shortage of research and innovation funds.
With China's entry into the WTO, the domestic in the intellectual property rights and technology constantly improve, increasing devotion of science innovation, professional and technical personnel, realize large-scale and specialization of production, efforts to shorten the large gap in plastic machinery technology both at home and abroad, has become the consensus of the man of insight in the field of plastic machine.
