Three types of plastics machinery market prospects look good Injection molding machine accounts for
Plastics machinery is the important pillar of the plastics industry development, which provides advanced technology and equipment for the plastics industry, its development is the foundation for the development of the plastics industry, are also affected by plastic industrial development. Around the world, of the three categories of plastic machinery varieties was followed by injection molding machine, extruder/extrusion production line and blow molding machine, they are more than 80% of the total output value of the plastic machinery, including injection molding machine for this more than half of the sum of the three kinds of machinery. The personage inside course of study thinks, the three types of plastics machinery market prospects look good.
A high content of science and technology injection molding machine needs strengthening. Due to injection molding machine before a few years development too fast, now in addition to the mainframe, injection molding machine has an oversupply of general specification, sales at about a third of the peak has been very good. But some of the injection molding machine with high content of science and technology, market demand is gradually strengthened. It is all electric, hydraulic precision injection molding machine. This kind of product main market is electronic communications, audio and video, home appliances, automobile, etc., processing conditions the demand is higher, it also improved precision requirements of the injection molding machine, these industries are sunrise industry, has the very big rise space. The second is the rapid development of hollow plastic injection machine. This is because the plastic parts under vibration condition of stress damage problems are car all plastic and some other big problems in engineering application, and combined with a variety of rubber and plastic materials with the use of hollow plastic injection technology, which can effectively improve the above defects. Three is auxiliary air, water, auxiliary device of new type of injection molding machine. This kind of technology has a lot of recent market, especially the appearance of the demand is higher, longer service life of products, such as household appliances, automobiles, building more attractive.
Domestic extruder lack of competitiveness. Extruder market due to the expanding of application market and technological breakthroughs, still can maintain a small change in the momentum on the whole, but domestic extruder market prices have been hard to avoid, churning out and price war has affected the whole image of the molding machine and domestic market competition, also hindered the development of plastic processing industry. The last two years, only a German Klaus? Murphy that a company can clinch a deal with China the arrival of more than one hundred production line, plastic doors and Windows and tubing processing most powerful enterprises to seek import equipment, it is the failure of the domestic manufacturer. Extrusion machine and production line in the future market will be to develop in the direction of technical content increase, the price is lower.
Domestic host now basically with conical twin-screw extruder and single screw extruder, the technology is mature, the market sales is the largest, but this kind of product has an oversupply of general specifications, can only maintain the market peak of 50% ~ 50%. The host in the future will focus on developing parallel to the twin screw extruder, is suitable for large amount of extrusion forming extrusion. Direction parallel double screw extrusion machine to the sixth and seventh generation high speed, with large length to diameter ratio. The development direction of single screw extruder is large diameter, large length to diameter ratio and exhaust flow. In fact, single screw extruder is a kind of low energy consumption, low cost, as long as the technology properly, it can basically achieve the performance of twin-screw extruder, such as the United States now use plastic extruder is most single screw, due to the high technical content, replaced the twin screw extruder.
The most development potential blow molding machine. Blow molding equipment prices low injection (about 1/3 ~ 1/2), low energy consumption (injection molding, the pressure inside the mold cavity is 15 ~ 140 mpa, and blow molding parison swell when pressure is generally less than 1 mpa), adaptive (forming complex structure, double-wall parts), it made up for the inadequacy of injection molding processing way, forming industrial parts with high integrity, good comprehensive performance, high added value, low cost
