Product Description Our Main Products:screw and barrel for extrusion machine screw and barrel for injection molding machine screw and barrel for food machine screw and barrel for rubber machine conical twin screw and barrel parallel twin screw and barrel bimetallic screw and barrel full-hard screw and other plastic machinery parts... Screw Barrel for Film Blowing MachineThe best single screw barrel for extruder in ZHONGYANG:The main advantage of screw barrel: A. Advanced Nitriding Technology B. Anti-corrosion and Wear-resisting Duplex Metal Spraying Technoloy C. We uses special alloy powders being sprayed and welded on the screw's ridge, and uses different alloy and welding methods for the screw of different functions.
