Plastic Machinery is an important pillar of the development of the plastics industry, plastics industry, it provides advanced technical equipment, its development is the basis for the development of the plastics industry, but also by the plastics industry development. From a global perspective, three main varieties of plastic machinery, followed by injection molding machine, extruder / extrusion lines and blow molding machine, plastic machinery output which accounts for more than 80%, which accounted for three types of mechanical injection molding machine combined more than half. The industry believes that these three plastics machinery market prospects. Injection molding machine as the development of rapid injection molding machine a few years ago, and now in addition to the mainframe, the general specifications of the injection molding machine has exceeded demand and the sales will remain at the peak of the 1 / 3 of the already very good. But some high-tech injection molding machines, the market demand is gradually strengthened. First fully electric, hydraulic injection molding machine precision class. These products main market is the electronic communications, audio and video, home appliances, automobiles, processing conditions require high demands on precision injection molding machine also increased, these industries are rising industry, there is much room for growth. Second, the rapid development of hollow injection molding machine. This is because the plastic parts in the vibration of the stress destruction of all plastics in automotive and other applications on the large number of engineering problems, and a variety of rubber and plastic material with hollow injection technology combined with application, can effectively improve the defects. Third, with the aid of air, water injection molding machine of new assistive devices. Such technologies have significant near-term market, especially the appearance of higher, long-lived products, such as home appliances, automotive, construction and other more attractive. Extruder machine market as the market continued to expand applications and technical breakthroughs, but also to maintain the overall momentum of rise slightly, but the domestic market prices fall extruder has been difficult to avoid, especially bad, and the price war has affected the domestic presses the overall image and market competitiveness, but also hindered the development of plastic processing industry. The last two years, only Germany Claus? Maffei, a company that deal with the arrival of China's more than 100 different profiles production line, plastic doors, windows and pipe processing industries most powerful enterprises to seek imports of equipment, which can not be said that the domestic the failure of manufacturers. Extruder production line host and technical content of the future market will be upgrading the direction of lower prices. Domestic hosts now essentially a conical twin-screw extruder and single screw extruder-based technology is relatively mature and has the largest sales market, but the general specifications of these products has exceeded demand and the market can only be maintained peak of around 50% -60%. The focus of future development of the host parallel to the twin-screw extruder different for a large amount of extrusion molding extrusion. Parallel twin screw extruder to the sixth and seventh-generation high-speed, large aspect ratio direction. Single screw extruder is the development direction of large diameter, large aspect ratio, exhaust and smooth. In fact, the single-screw extruder is a low-power, low-cost model, as long as the technology properly, it can basically achieve the performance of twin-screw extruder, such as the United States is now used on most of the plastic extrusion machine is a single screw, due to high technology to replace the twin-screw extruder. Blow molding machine blow molding equipment for lower prices (about 1/3-1/2 injection), low energy consumption (injection molding, the mold cavity pressure for the 15-140MPa, while the parison when the winds blow inflation pressure is generally lower than 1MPa), adaptability (can be formed complex, double-wall of the workpiece), which make up the shortcomings of injection molding, molding of industrial workpieces with a high degree of integrity, good overall performance, value-added High, low cost. Thus, although the current blow molding machinery in the three lowest proportion of presses, but in the future will maintain strong momentum, is the fastest growing and most development potential of the model. Plastics industry in China ,2000-2005 long-term planning for plastic products, the average annual growth rate of about 10% ,2006-2015 annual growth rate of 8%. By 2005 the output of plastic products will reach 25 million t, plastic products output is expected to double by 2015, to 50,000,000 tons. Plastics processing industry will continue to be good prospects for the development of plastic machinery manufacturing industry in China source for the rapid development, projected 2001-2010, China's demand for plastic machinery 6% average annual growth rate is expected to 14.5 billion in 2010 element.
