China's Top Flat Coil Spring Manufacturers

Zhejiang Lisheng Spring Co., Ltd.: Founded in 2009, it is a private enterprise specializing in the design and production of wave springs and spiral retaining rings. It has become the largest wave spring and spiral retaining ring production base in China. It can provide products of various materials, and introduce advanced equipment and software to quickly produce non-standard products.

Shandong Zhiheng Vibration Damping Technology Co., Ltd.: It is a designated manufacturer of locomotive and vehicle parts for China Railway Corporation and a designated core supplier of spiral springs for Fuxing EMUs. The spiral damping springs it produces are of stable quality and have many patents. The products are not only used in the railway field, but also involve shock-absorbing spring products such as construction and ships. However, it does not explicitly mention whether it produces flat coil springs. However, due to its technology and scale in the field of coil springs, it is possible to produce related products.

Shanghai China Spring Manufacturing Co., Ltd.: Founded in 1937, it is affiliated to Shanghai Automotive Group Co., Ltd. and is one of the earliest OEM suppliers of automotive springs in China. It mainly produces automotive suspension springs, engine valve springs, stabilizer bars and mold springs, various types of super-large coil springs, special-shaped springs and other spring products. Although it does not explicitly state that it produces flat coil springs, it is possible to produce such springs due to its rich product variety.

Henan Huihuang Spring Co., Ltd.: It can customize various flat springs, coil springs and other spring products. Its flat springs are compression springs, with various cross-sections and shapes of materials used, which can meet certain customization needs.
