Since highly efficient extrusion machine has been made by attaching cylinder screw which was processed with special materials and lastest heat treatment, the superiority is being received recognition anywhere even for the high speed extrusion as well as extruding of soft and hard P.V.C, PS foaming and P.V.C forming.

 We produce screw & barrel in order to prevent abraison caused by extruding friction through heat treatment in stages of SACM nitriding steel, and then screw
