A compression spring is a spiral spring that bears axial pressure

Compression spring is a spiral spring that bears axial pressure. Because it can bear pressure, both ends can be open or closed, or wound flat or ground flat.

 

The cross section of the material used is mostly circular It is made of rectangular and multi strand steel coils. The spring has equal pitch and variable pitch. The shape of compression spring is cylindrical, conical, convex and concave, and a small number of non-circular or even various tail end variants.

 

The products can be shaped according to the design. There is a certain gap between the coils of the compression spring. When subjected to external load, the spring shrinks and deforms and stores the deformation energy.
