We are able to take mapping, design for clients and make products as per customer's drawing or existing sample
- 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
