Tianjin Wang xia Spring Co., Ltd. was founded in 2005 and located in Jinghai County, Tianjin , China . It is very convenient for transportation east of Tianjin port.
Our company is the professional manufacturers which combine a set of spring manufacturing, R & D with surface
According to the nature of the force
According to the nature of the force, the spring can be divided into a tension spring, a compression spring, a torsion spring and a bending spring. According to the shape, it can be divided into a disc spring, a ring spring, a leaf spring, a coil spring, a truncated cone scroll spring and a torsion bar spring.
According to the production process, it can be divided into a cold coil spring and a hot coil spring. Ordinary cylindrical springs are widely used because they are simple to manufacture and can be made into various types according to the load conditions. Spring manufacturing materials should generally have high elastic limit, fatigue limit, impact toughness and good heat treatment properties.
Commonly used are carbon spring steel, alloy spring steel, stainless spring steel, and copper alloy, nickel alloy and rubber. Wait. Springs are manufactured by a cold roll method and a hot roll method. The general-purpose cold-roll method in which the spring wire diameter is less than 8 mm and the hot-roll method in which the spring wire diameter is larger than 8 mm. Some springs are subjected to strong pressure or shot peening after being made to improve the load carrying capacity of the spring.
