Quality Nitrided Screw for Plastic Injection and Extrusion

 

Quality Nitrided Screw For Plastic Injection and Extrusion

 

Our nitriding screw barrels have excellent thermal conductivity, which can help to optimize the plasticizing process and reduce energy consumption.

They are widely used in various plastic machinery, such as injection molding machines, extruders, and blow molding machines. Also, they have been widely recognized by the plastic industry due to their outstanding performance, especially in the processing of high-temperature and high-viscosity materials.
