          The products are used in a corotating twin screw extruder, is the same to the main vulnerable parallel twin-screw extruder parts and accessories. Screw element is the main component of twin screw extruder, extrusion materialquality stability depends entirely on the quality of screw element.

          The material selection of high quality W6MO5CR4V2 materials and nitriding steel (38CRMOALA) after quenching and tempering, inspection, high temperature vacuum quenching (nitrogen), Seiko polishing process ofproduction, has the characteristics of precision, wear resistance, corrosion resistance and oxidation resistance at high temperature, long service life. To ensure that customers will extrusion machine downtime to a minimum.According to the space meshing principle, screw thread of screw elements andkneading block engagement surface curve, generated by computer optimization design method and AutoCAD, to ensure the high speed with twoscrew to maintain the minimum backlash on the same, the residence time of the materials can accurately control and narrow distribution and uniform, andself-cleaning properties very good.
