As the twin screw extruder moves toward high speed and high torque, higher requirements are placed on the strength (especially thermal strength) and accuracy of the twin screw extruder shaft, Through extensive research and painstaking research, our company adopts impots impoted pre-hard alloy tool steel from Germany. The spline processing adopts cold rolling processing of imported CNC equipment form Europe. The products have been tested by customers and fully meet the performance quality requirements of similar imported high end products.
