Material: Base material 38CrMoAlA, Welded inlay on the flight, prolong life of screw. Easy wearing parts of barrel feed inlet made from imported anti-wear alloy can be improvde abrasion performance
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 changed according to different products and output
Technological Process can be chosed acoodring to your requirements
