A torsion spring generates torsional torque, or moment, from the central axis of the coil. The spring is wound in a cylindrical shape. It is used to apply force in the direction in which the spring is twisted relative to the coil’s axis. Aoi Spring has the latest equipment to work the arm into complex shapes, such as a curve or hook. A double torsion spring helps reduce parts and boost operation efficiency in situations where two springs would normally be used and wound in opposite directions.
