Compression springs are coil springs that are subjected to axial pressure. The cross-section of the materials used is mostly circular, and they are also rolled with rectangular and multi-strand steel. The springs are generally of equal pitch. The shapes of the compression springs are: cylindrical, conical There is a certain gap between the rings of the compression spring, and the spring shrinks and deforms when it is subjected to an external load, storing the deformation energy.

Compression springs provide resistance to external load pressure. Compression springs are generally wire coiled at equal pitches and have a fixed wire diameter. Compression springs use multiple open coils to provide resistance to external load pressure. That is, they push back against external pressure. Compression springs are generally wire coiled at equal pitches and have a fixed wire diameter.

In addition, there are also conical compression springs, or a combination of conical and linear springs. Depending on the field of application, compression springs can be used to resist pressure and store energy. Round wire is the most commonly used compression spring, but there are also compression springs made from square, rectangular, and specially shaped wires.
