REMARK:
- We are able to take mapping, design for clients and make products as per customer's drawing or sample excellently , also can help customer to repair the old screw and barrel by useing bimetallic-alloy process
- Screw structure, compression ratio and material can be changed according to different products and output.
- Technological Process can be chosed acoodring to your requirments.
- Commonly used materials: 38crMoAIA, nitrogen treatment . Various high quality alloy steels , 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
The foreign material we used as following:
