New plastic extruder and production line future market will be to high technology content, price reduction in the direction of development, domestic plastic extruder is now basically tapered twin-screw extruder and single screw extruder mainly, technology is more mature, the largest market sales, but the general specifications of such products have exceeded demand, can only maintain the peak market period of 50% ~60%.
Plastic extruder in the future, the emphasis is on the development of parallel twin-screw extruder, suitable for large extrusion molding extrusion, parallel twin screw extruder to the sixth generation, the seventh generation of high-speed, large length-diameter ratio direction. The development direction of single screw extruder is large diameter, large length diameter ratio and smooth exhaust.
In fact, single screw extruder is a kind of low energy consumption, low-cost models, as long as the technology is appropriate, it can basically achieve the performance of twin-screw extruder, such as the United States now used plastic extruder on most of the single screw, due to high technical content, replaced by twin-screw extruder.
