REMARK:

We are able to take mapping, design for clients and make products as percustomer's drawing or sample excellently , also can help customer to repair theold screw and barrel by useing bimetallic-alloy process
Screw structure, compression ratio and material can be changed according todifferent products and output.
Technological Process can be chosed acoodring to your requirments.
Commonly used materials: 38crMoAIA, nitrogen treatment . Various highquality alloy steels , according to different usage, the choose for alloy isdifferent, some require for abrasion-resistant while some require forcorrsion-resistant. For standard, we have Fe-based, Ni-based, W2C alloy,Tunstenalloy etc for choice
