In the Chinese market, single screw plastic extruder as a pillar industry in the plastic machinery, occupies the very big development advantages, more stronger gradually in the market, it has a simple structure, strong and durable, easy maintenance, low cost, easy operation etc., and in the process of developing, technology upgrading, development in the direction of high quality, high efficiency and more functional.
Plastics machinery is a pillar industry in the development of plastic industry, 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, varieties of plastics machinery is mainly composed of injection molding machine/extrusion line, plastic extrusion machine and blow molding machine of three categories of products, they are more than 80% of the total output value of the plastic machinery, market popularity at the top. The injection molding machine and accounts for more than half of these three kinds of mechanical combined.
Due to injection molding machine before a few years development too fast, now in addition to the mainframe, general specifications of the injection molding machine has an oversupply, but some of the injection molding machine with high content of science and technology, market demand is gradually strengthened. Basically has the following models:
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 great development space.
The second is 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 (HotTag) injection molding 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 new type of injection molding machine has a very large market, especially for cosmetic requirements higher, longer service life of products, such as household appliances, automobiles, building more attractive.
After the industry technology, research and development personnel to the joint efforts of some of the major special models such as exhaust extruder, tandem mill screw extruder, reciprocating pin extruder of snail, foaming extrusion machine, with the melt gear pump extruder, tandem multistage extrusion machine, planetary screw extruder are manufacturers in China, has the independent research and development ability, and enjoy independent intellectual property rights.
Plastic extrusion machine and production line in the future market will be developed to the direction of high technical content, 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.
