REMARK:

We are able to takemapping, design for clientsandmake products as per customer\'s drawingorsample excellently, also can help customer torepair the old screw and barrelby useing bimetallic-alloy processScrew structure,compression ratioandmaterialcan be changed according to differentproducts and output.Technological Processcan 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
