XIAYI’s Uniform Hardness Finished Base Valve is a precision powder metallurgy component designed for shock absorber manufacturers seeking ready-to-assemble quality and lower secondary processing costs. Made from FC-0208 iron-copper material, it combines uniform hardness control, precision sizing and finished surface machining, with dimensional tolerance up to ±0.005mm and flatness ≤0.007mm.

Based on nearly 20 years of powder metallurgy research and manufacturing experience, XIAYI has developed the Steam-Treated Base Valve with Stable Hydraulic Damping for automotive, motorcycle and new energy vehicle shock absorber applications. By combining FC-0208 iron-copper powder metallurgy materials with professional steam treatment technology, XIAYI improves structural density, surface durability and hydraulic stability.

The accuracy of hydraulic oil flow control, sealing surface quality and internal component consistency directly affects vehicle handling, driving comfort and product service life. Developed by XIAYI, the Deburr-Free Base Valve with Optimized Orifice Layout adopts advanced powder metallurgy technology, optimized hydraulic channel design and precision manufacturing processes to improve oil flow stability and assembly reliability.

Designed for demanding shock absorber applications, XiaYi Corrosion-Resistant Stamped Spring Seat is manufactured by an experienced automotive component supplier in China. Using high-strength steel stamping and durable anti-corrosion surface treatment, it maintains reliable load support, rust protection and structural integrity in humid and harsh environments. XiaYi delivers customized spring seat solutions for passenger vehicles, EVs, commercial vehicles and engineering machinery.

The Uniform Hardness Sintered Rod Guide from XIAYI is designed for shock absorber applications where consistent wear and long-term stability are critical. Using FC0208 powder metallurgy material, controlled sintering and uniform hardening technology, it maintains a hardness range of 70--90HRB across the working area. This helps reduce localized wear, friction variation and premature performance loss during repeated piston movement.

The Optimized Dimension Rod Guide For Oil Seal Matching from XIAYI is developed around one critical requirement of shock absorber assembly: achieving a reliable dimensional interface between the rod guide and oil seal. Instead of using a universal tolerance range for every application, XIAYI evaluates key fitting dimensions, concentricity, end-face geometry and chamfer design according to different sealing requirements. This approach helps reduce installation interference, uneven sealing pressure and oil seal lip damage during piston rod movement.
