  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.     We can make any specification of extruder screw barrel and injection screw barrel for Haitian, Demag, Engle, Nigro bossi, arburg, NPM, BOY, Husky, Fanuc, billion, Sumitomo, Nippon Steel, Toshiba, Nissei, Mitsubishi and etc. We also can supply all types of screw and barrel according to your different requirements.   Want to know more information about our products?         Mona will be very happy to answer your questions in 24 hours.        Skype:sales3@oushengda. com
