Scope of application
WPC sheet,pallets,pinch,pipe,profiles,soft pvc,pvc foam sheet,etc.
We are able to take mapping, design for clients and make products as per customer's drawing or existing sample. For good plasticizing effect,we have different design of screw & barrel to meet your requirements
Material:
Commonly used material is 38crMoAIA(nitrogen treatment),it can be changed as per your requirements. According to different usage, the choose for alloy is different, some require for abrasion-resistant while some require for corrsion-resistant. For standard, we have Fe-based, Ni-based, W2C alloy,Tunsten alloy etc for choice
Screw structure and compression ratio can be designed according to different products and mixtures
