The production line can produce PE, PP or PVC wood plastic profile products, mainly used for pallets, packing boxes, floors, outdoor decoration materials, etc., and has a wide range of uses. Wood powder and plant fiber are high (up to 50-75%); the equipment has strong adaptability. Special designed screw barrel, die and extruder are used to produce wood plastic products. Extruder single two-stage mixing direct extrusion, or two-step extrusion after granulation, saving power and space, with high output, stable extrusion pressure, preheating feeder placed on the top of the main machine, first extract most of the residual moisture in wood flour, so that the feeding section of the main machine is more substantial; good plasticizing mixing effect. The optimized screw design makes the cutting small, not easy to cut off the wood fiber, and can make the material stay in the machine evenly. The screw barrel adopts bimetallic treatment, which is wear-resistant and corrosion-resistant, and its service life is greatly prolonged.
