Frequently Asked Question

Do you have any question?

Our compression springs can be used in automotive hardware accessories, electrical equipment, electronic products, medical equipment, aerospace, fitness equipment parts, industrial equipment, mechanical parts, office equipment, children's toys and other fields.

Advantages of our springs: Springs have a very wide range of applications and are suitable for almost every industry. We have a wealth of raw material storage and can quickly manufacture springs. Our springs have good elasticity, high temperature resistance, environmental protection and no pollution, strong pressure resistance, corrosion resistance, suitable for Wide range and so on.

Our springs offer custom services. Including the size, material and packaging of the compression spring, it can be customized according to customer requirements.

1.The specifications of each spring are different, and the design has been determined, and the compression spring should not be easily replaced with each other when used, nor can it be modified at will. 2.When repairing and maintaining the mold, the old and new springs should not be mixed in different applications, which will cause the spring to receive uneven load, which is the failure of the spring with large load. 3.Repairers often correct the standard spring due to the lack of suitable springs in use, such as truncation, grinding the inner and outer diameters or series springs, which will cause the spring to not adhere to the original characteristics, resulting in premature failure.
