The Direction of the Development of Plastic Extruder Machine
The future market of new Plastic Extruder Machine
and production lines will develop in the direction of high technical content and low price. Domestic extruders are now mainly based on conical twin-screw extruders and single-screw extruders. The technology is relatively mature and the market sales are also the largest, but the general specifications of such products have been
oversupplied and can only maintain the peak of the market.
The future focus of plastic extruder line
is to develop parallel counter-rotating twin-screw extruders for forming extrusions with large extrusion volumes. Parallel co-rotating twin-screw extruders should be developed in the direction of the sixth and seventh generations of high speed and large aspect ratio. The development direction of the single-screw extruder is large diameter, large aspect ratio, and smooth exhaust. In fact, the single-screw extruder is a low-energy, low-cost machine. As long as the technology is right, it can basically achieve the performance of the twin-screw extruder. For example, the plastic extruders currently used in the United States are mostly Single screw, because of the high technical content, replaced the twin screw extruder.
The new high-end plastic extruder has the advantages of high efficiency and high productivity, which enables investors to obtain larger output and high return with lower investment, but the precision of auxiliary equipment and control system must be improved, screw and barrel The increased wear and tear requires high wear resistance and ultra-high wear-resistant materials, and the reducer and bearing improve their life at mature high speed operation.
