DYMACHINE Factory Customized Metal Springs -compression，extension，torsion

According to the nature of the force, hardware springs can be divided into tension springs, compression springs, torsion springs, and special-shaped springs.

Compression spring (compression spring) is a spiral spring that bears axial pressure, usually coiled with metal wire of equal pitch and fixed wire diameter. Compression springs use multiple open coils to provide resistance to external pressure.

The working principle of a extension spring is opposite to that of a compression spring. Compression springs act in the opposite direction when compressed, while tension springs act in the opposite direction when extended or pulled apart. When the two ends of the stretching spring are pulled apart, the spring will attempt to pull them back together.

Torsion springs belong to spiral springs. The end of the torsion spring is fixed to other components, and when the other components rotate around the center of the spring, the spring pulls them back to their initial position, generating torque or rotational force. A torsion spring can store and release angular energy or statically fix a device by rotating the force arm around the central axis of the spring body.

The difference between irregular springs and conventional springs is that the spring itself is irregular, with bending and a large number of complex angle designs. Suitable for some special occasions.
