Professional design PP PET ABS Extruding Machines Screw Barrel/38 CrMoALA nitriding single screw barel for plastic extruder

38 CrMoALA nitriding single screw barel for plastic extruder 1.Custom Production 2.Quality Material Used 3. Wear-resistant

Professional design PP PET ABS Extruding Machines Screw Barrel/38 CrMoALA nitriding single screw barel for plastic extruder

     Screw barrel manufactured with high-quality nitro alloy steel, applying the method of hardening and tempering and nitriding, thus it enjoys the characteristics of long working life, wear resistance, and anti corrosion. Besides, the technique of hard alloy spraying or chrome plating can be used on the working surface of screw, which will make it have better using effectiveness.
