The induction hardening process creates a martensitic microstructure in the surface layer while maintaining ductility in the core material. This dual-property configuration provides excellent resistance to pitting and fatigue failure. Spline teeth undergo profile grinding after heat treatment to maintain dimensional accuracy within 0.01mm tolerance. For specialized applications, we offer various surface coatings including phosphating and black oxide treatment upon request.
Backed by ISO 9001, TS 16949, and ISO 14000 certifications, our manufacturing processes undergo regular audits to ensure consistency. With direct shipments available from Shanghai, Qingdao, Tianjin, and Lianyungang ports, we efficiently serve global markets including North America, Europe, and Southeast Asia. Our 10,000-30,000 sqm production facility enables flexible batch sizes from prototypes to mass production. Experience the reliability difference – contact our engineering team today for customized solutions matching your exact transmission requirements.
