Conical Twin Screw Barrel

Twin screw and barrel are made of high quality 38CrMoAIA, 42CrMo, 304 stainless steel and other materials from well-known manufacturers in domestic and abroad. The advanced nitriding process, corrosion resistant and wear-resistant bimetal spraying process are adopted to meet the technical requirements and improve the wear resistance of screw, prolong the service life.
