Volute Springs

Wire forms can have a shape that is limited almost only by fantasy. Many of them have some kind of spring functionality, for example some quick fastening applications. In most products, the material is stressed in bending and they can be looked upon as leaf springs made from wire. Wire forms are manufactur

Multi-coil wave springs are made from flat-rolled spring wire that is coiled to a helical shape and the coils are at the same time given a sinus shaped wave form. The force-deflection relation is created by flattening out the wave form when the spring is compressed. The function is hence like a helically shaped leaf spring.

Many applications require two similar springs, but with one right-hand coiled and one left-hand coiled. In some cases, these two springs can be combined into a double spring, which has one right and one left-hand coiled spring body connected to each other.

Torsion bar springs is a good alternative to clock springs or helical torsion springs, when a rotational torque is needed in applications where the spring shall fit into a space that is limited radially, but with lots of space axially.
