Scope of application
WPC sheet,pallets,pinch,pipe,profiles,soft pvc,pvc foam sheet,film,tape,recycled,tape tube,water pipe,drainage pipe,etc.
For good plasticizing effect,we have different designs of screw and barrel for extruder or injection to meet customer’s demand. Our factory manufactures with high-quality material, applying the method of hardening and tempering and nitriding, thus it enjoys the characteristics of long working life, wear resistance, and anti corrosion. Besides, the technique of hard alloy spraying or chrome plating can be used on the working surface of screw, which will make it have better using effectiveness.
Competitive Advantage:
All dimensions including out diameter, Hole size tolerance, Root diameter,Parallelism of end surface,Verticality are in accordance with technical data.
