Factory Direct Shock Absorber Piston for Reliable Performance

XIAYI specializes in the development and manufacturing of shock absorber components, providing precision solutions for global automotive and motorcycle suppliers. With extensive experience in powder metallurgy, automated production, and suspension component manufacturing, XIAYI supports customers from product development to mass production.

The Shock Absorber Piston manufactured by XIAYI is designed as a key internal component of hydraulic suspension systems. Through precision forming, machining, and surface treatment processes, the piston helps regulate oil flow, maintain damping force, and improve suspension response under different driving conditions.

Working Function

Hydraulic Flow Control

Inside a shock absorber, the piston controls the movement of hydraulic oil between chambers through designed oil passages and valve structures. Accurate piston design directly affects damping performance and driving comfort.

Damping Force Adjustment

Different vehicles require different damping characteristics. XIAYI develops piston structures according to customer requirements, helping suspension systems achieve suitable balance between stability, comfort, and handling performance.

Product Structure Design

Oil Passage Design

The number, size, and position of oil holes influence hydraulic resistance and oil circulation efficiency. XIAYI optimizes internal structures based on application conditions to achieve stable operating performance.

Precision Dimension Control

Accurate outer diameter, thickness, and groove dimensions are important for proper assembly with other shock absorber parts. Strict dimensional control helps reduce fitting problems and improves overall reliability.

Material and Manufacturing

Powder Metallurgy Production

Many pistons are manufactured through powder metallurgy processes because this technology provides good material utilization, stable density, and suitable mechanical properties for repeated movement applications.

Surface Performance Improvement

According to customer requirements, XIAYI applies suitable finishing processes to improve wear resistance and surface durability, allowing products to maintain stable performance during long-term operation.
