In the heat treatment should pay attention to their deformation problem, think of a way to put, so as to choose a more suitable heat treatment device. Under the premise of being able to repair, several times of tempering and hot pressing can be carried out, and the cable distance can be adjusted as required during winding. The screw distance can be 3 ~14 times the diameter of steel wire, but it is better when it can be 8 ~13 times as normal.

There are also a lot of precautions in the use of special-shaped spring, such as how to prevent failure, spring under the combined action of cyclic load and corrosive medium fracture, under the combined action of tensile stress and corrosive medium spring fracture phenomenon, so customers should pay more attention to.

Stretch spring manufacturers, torsion spring manufacturers, shaped spring manufacturers
