Springs which work in twisting motion are known as Torsion Springs applying a resistance in the twist (a torque). Generally, torsion springs are used when the spring tightens. Problems can occur if the spring is used in an opening twist and is not recommended.

We manufacture open or closed wound torsion springs in wire diameters from 0.1mm – 3.20mm (0.0004″ – 0.125”) on CNC machines and up to 5mm on coiling lathes, all with specified spring ends to meet all applications and assembly situations. Torsion springs can be produced with multiple bends and double torsion. All processes are subject to quality control at every stage of production.

The advent of CNC wire forming machines has enabled engineers to design myriads of end forms. Torsion springs can be single coiled body or double bodied known as double torsion.

There are a wide range of uses for torsion springs and are normally used over a mandrel. Acme Springs manufacture and supply a wide range of torsion springs from small torsion springs used in electrical equipment and up to large diameter springs used in hinges and lids.
