The extruder can extrude plastic directly after double-stage mixing, also can extrude in double-stage method after pelletizing, which save electricity and space, features high extrusion capacity and stable extrusion pressure. The preheat feeding device is installed on the top of the main machine, which can extract most of the moist in the wood powder, make a better feeding, with excellent melting effect. The optimized screw design results in a small shear, which makes it hard to cut the wood fiber, therefore, enables a stable dwell time of the material in the machine. The screw and barrel were under of bimetal treatment, so they have the advantages of corrosion-resistance, wear-resistance, and long service life.
This production line is able to produce PE, PP or PVC with Wood profile products. The WPC profile is a new type environment friendly product, because it uses plastic and waste wood fiber powder as the raw material, add certain proportions of auxiliary additives, foamed agent. The composite profile is extruded under high temperature and pressure, therefore the production line is used to produce pallets, package box or board, window sills, decorating floor and outdoor decorating product, which are widely used these days. The wood or nature fiber powder can account a high proportion (at most 50-70%); The production line is multi-functional, which can also be used to produce PP, PE, PVC, ABS and PS products.
