Design requirements of double alloy screw barrelDesign requirements of double alloy screw barrel
The bimetallic screw barrel bimetallic process is a more commonly used process combination product with excellent corrosion resistance and wear resistance in recent years. It adopts HVOF high-speed spraying equipment to melt spray spray the surface of the screw to obtain a densely structured bimetallic screw. ; The bimetallic barrel adopts the method of melt casting, casting the alloy with high tungsten carbide content into the barrel body, using special engineering technology, precision molding.
Advantages of double alloy screw barrel: more wear-resistant, good mixing effect, good dispersion.
Screw diameter: φ15-φ300
Aspect ratio: 15-46
Product type: For different plastic products, screw can be used: ordinary type, pin type, barrier type, separation type, exhaust type, etc.
Treatment process: heat treatment, nitriding treatment.
