WPC PULVERIZING + MIXER SYSTEM In the production process of Wood Plastic Composite (WPC), natural fiber can mix with 30%-80% of the polymer. Therefore, the selection of natural fiber (sawmill, chipboard, rice husk, etc.) is important. All natural fiber must pulverize as 40mesh~120mesh of particle size. WPC PRODUCTION LINE The use of natural fibers in extruded profiles is becoming increasingly popular. Attempts have been made to develop new features of finished wood-plastic composites (WPC), such as PP/PE resin mixing 40-80% natural fiber or PVC mixing 40-70% natural fiber. To meet the quality requirements, Everplast has developed a segmented twin screw extruder with special single screw extruder line as well as a parallel twin screw extruder with special single screw extrusion line combining tooling die head and all downstream equipment. WPC MOLDS The WPC profile mold design divides into hot extrusion molding and cold extrusion molding. The hot extrusion molding line speed is approximately 0.3~1 m/min. The special design of a sink insulation system is capable of increasing the production speed; as the high wood powder content reaches 60%, the cold extrusion molding technology can ensure that the center thermoplastic wood material does not penetrate through the skin layer. As a result of a slow production speed (0.3~1m/min), the rear end pulls without dragging the whole thing off. Hot extrusion molding: the average temperature of plastic mold is greater than the melting point (Tm). For the first sizing mold, the skin temperature (T) must be lower than the curing temperature (Ts),
