Shanxi Jianing Forging adopts mature precision die forging processes, capable of producing gears, valve bodies, automotive swing arms, piston rods, and impeller die forgings. It offers high dimensional accuracy, and can be processed from carbon steel, stainless steel, and alloy steel, meeting the needs of multiple industries.
Does your coupling frequently fail due to insufficient strength or precision deviations, leading to frequent equipment failures and high maintenance costs? Jianing Forging uses fine die forging technology to solve the problems of traditional couplings prone to deformation and short service life from the source, providing you with highly reliable, long-service coupling die forgings.

Coupling die forgings are relatively high-strength transmission components made from high-quality alloy steel, finely forged, heat-treated, and machined. With mature die forging technology, Jianing Forging achieves dense internal structure, complete streamlines, and high dimensional accuracy, meeting the high torque transmission and coaxiality requirements of various mechanical transmission systems. We support customers in customizing according to drawings, with full control over the entire process from materials to finished products, ensuring consistent quality in every batch.
Superior materials: Selected from high-quality alloy steels such as 40Cr, 42CrMo, and 20CrMnTi, rigorously re-inspected for stable mechanical properties.
Fine die forging: Uses closed die forging technology, resulting in no flash and small allowance, with dimensional tolerances up to ±0.3mm, reducing subsequent processing.
Performance enhancement: After forging, quenching, tempering, or carburizing and quenching treatments balance tooth hardness and core toughness, significantly improving fatigue resistance and lifespan.
Surface treatment: Available with anti-rust processes such as bluishing, phosphating, and galvanizing, suitable for environments with high salt spray and humidity.
