Our company specializes in manufacturing various types of Leaf Springs for commercial vehicles, passenger cars, and trailers. With over more years of experience in the automotive suspension industry, we provide durable, high-load-bearing solutions that ensure vehicle stability and riding comfort.
A leaf spring is a simple form of suspension, commonly used for heavy-duty vehicles. It is designed to absorb shocks, maintain ride comfort, and support the vehicle's axle and load. Our leaf springs are engineered to provide optimal stability and longevity.

Corrosion-resistant and rust-proof
Vehicle Applications:
Shearing & Punching: Steel bars are precisely cut and punched to form the initial shape of the leaf.
Heat Treatment (Quenching & Tempering): Leaves are heated to austenitizing temperature and rapidly quenched in oil, followed by high-temperature tempering. This critical process enhances the spring's tensile strength and resilience. We utilize fully automated CNC heat treatment lines to ensure temperature uniformity.
Shot Peening: The surface of the spring is bombarded with small steel shots. This process induces compressive residual stress, significantly reducing the risk of crack formation and extending fatigue life by up to 300%.
Scragging (Pre-setting): Springs are compressed to the solid height to set them permanently. This prevents settling during actual vehicle use.
Assembly: Leaves are assembled with center bolts, clips (rebound clips), and bushings. The clips are tightly clinched to prevent leaf separation.
