The wave spring, an innovative design originating in the United States in the 1970s, stands out for its two significant advantages. First, under identical load conditions, its working stroke can be reduced by up to 50%, effectively saving space while reducing its own weight by 70%. Second, this spring is manufactured from thin steel strips through specialized processing techniques, allowing production in both single-layer and multi-layer configurations; whether wave springs or flat-ring wave springs, they meet various application requirements. Additionally, its design effectively prevents excessive outer diameter expansion during compression, thereby avoiding interference with workpieces.

Jiangsu Sunzo's wave springs are widely used in various fields such as aerospace, nuclear power, high-speed rail, and new energy vehicle drive motors. In the aerospace sector, wave springs provide stable elastic support for precision components of spacecraft, ensuring reliability under extreme conditions; in nuclear power applications, they are employed in critical reactor equipment to guarantee safe operation of nuclear facilities; in high-speed rail systems, they serve as essential components of braking systems, ensuring effective train braking; in new energy vehicle drive motors, their compact structure and superior performance significantly reduce internal motor space while enhancing efficiency and reliability.
