Torsion springs, are a type of mechanical springs that work by twisting or rotating around their own axis of the elements cooperating with the spring. The primary function of torsion springs is to store and release energy under the influence of a torsional force (moment of force). They are usually made of spring steel wires that meet the requirements of EN-10270-1. Torsion springs are commonly used in various applications such as mousetraps, garage doors and laundry clips to provide torque or rotational force. These springs can come in different shapes and sizes depending on their purpose and the force they need to exert. The force a torsion spring can exert depends on its physical parameters, such as wire diameter, number of coils and, to a lesser extent, the material used.
