Plastic extrusion molding process on how to improve the dimensional accuracy of the product

　　Need to increase production, reduce energy consumption, low temperature extrusion, longer machine life. Since the installation of the extruder the polymer melt pump, the pressure is transferred to the function of the extruder gear pump is completed, the extruder can be operated at low temperature and pressure state, the leakage flow is greatly reduced, the yield is improved. Gear pump more efficiently than the extruder head pressure established, and reduce the back pressure of the extruder, the screw withstand axial forces fall and prolong life.
