The PP wood and plastic profile extrusion production lineis the use of special design of screw extruder barrel, mould and machining process production wood and plastic products.Extruder two single level directly extrusion, also can be mixed granulation two-step after extrusion, save electricity, save space, with high output, extrusion pressure stable, preheat the machine on the top, and most of the first host out wood powder residual moisture, make host for the more enrichment; Plasticizing mixed refine effect is good wait for a characteristic. Optimization design of screw shear small, is not easy to use cut wooden fiber, can make the material in time even stay in the machine. Screw extruder barrel with double metal processing, wear-resisting corrosion resistance, service life greatly extended.The PP wood and plastic profile extrusion production line line can produce PE, PP or PVC wood and plastic different profile products, mainly for the tray, packing cases, floor board, outdoor decoration materials, use very extensive. Wood powder and plant fiber add volume is high (maximum of 50-75%); Equipment, strong ability to adapt and processing PP, PE, ABS, PS, etc.
