Material can be extruded out directly after two grades of mixing, and it can also be extruded by two steps after pelleting. The lne is of characteristics of energy and space saving, high output, stable performance etc. Preheating feeder is installed at the top of extruder, which will dry the wood power firstly, thus perfect plasticization is guaranteed, special-design screw will minimize cutting force, which provents wooden fiber from being damaged. Both screw and barrel are speacial-treated, which are featured of abrasion proff and long life-span.

This production line is consisted of conical twin-screw extruder, vacuum calibration table, haul-off unit and stacker, and also coordinated with different kinds of moulds to produce PVC door & window profiles, foamed special-shaped profiles, decoration plates etc.

The products PP/PP or PVC wood plastic compound profiles are of wide appliaction, which are mainly be used for trays, box boards, flooring, ourdoor decorative materials and so on, the wood and plant fiber increasing rate is very high (up to 50-70%), and the line is of good adoptabillity, which can be used for process different materials such as PP/PE/PVC/ABS/PS and so on.
