Description

This production line adopts the optimal designed high-efficiency single-screw extruder and conical double-screw extruder. It can mix recycled plastic such as PE, PP, PVC and plant fiber such as sawdust, saw powder, straw, wheat bran, rice husk sufficiently, and make them into WPC board under special process craft. The main molding modes for the WPC production include extrusion molding, thermo-compression molding, injection molding, blow molding, etc. Among them, the one with prominent features, widely application and most mature technology is the extrusion molding mode. Main machinery for the WPC extrusion molding include mixing machine, granulator, single or double-screw extruder, three-roller calendaring machine, cooling bracket, haul-off machine, plate shearing machine and material reversal stacker, etc. WPC material is made from modified thermo-plasticity plastic after the strengthened treatment of wood fiber. With advantages of both wood and plastic in cost and property, it can be used to produce profiles, plates and other products after extruding and calendaring treatment. WPC products are mainly used to replace wood for its features of being water-proof, mothproof, environmental-friendly, etc.
