How to choose good quality segment screw element

Double screw extruder has good plasticizing performance and stable extrusion and other advantages. The surface of segment screw element is usually sprayed with double alloy, which can effectively extend the service life of the screw. Here today, we will share how to choose good quality segment screw element with you. 

1. Check the raw materials of the screw. High quality segment screw element is made from high quality raw materials, which can provide sustained, stable high-yield. 

2. Check the surface of the segment screw element. High quality segment screw element is usually sprayed with nickel-based alloy powder or tungsten carbide alloy powder, which can greatly improve the wear resistance of the screw to extend the service life. 

3. Check the manufacturing process. High quality segment screw element needs go through multi- processes to reach the technical requirements. 

4. Check the capability of segment screw element manufacturer. Professional segment screw element manufacturers can fully absorb the advanced technology to design specific requirements for customers.
