Double Screw Spare Part For Extruder Screw Barrel Clasps
1. Descriptions
Using the world's advanced coating technology,to create high wear and corrosion threaded element products.
High-performance,high wear resistance of the screw element,can significantly improve product quality and
consistency effectively reduce the machine to replace the screw element frequency,will minimize production
costs.
All of our twin screw extruder elements are finished by CNC grinding after heat treatment. The surface roughness of this series is less than Ra0.8, which completely eliminates the influence of heat treatment deformation on the quality of components.
