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.

Volute Springs are used as compression springs and made from flat material coiled to a volute. The coils of the material overlap each other and are guided radially by each other during compression, thus giving the spring a stability against buckling that cannot be achieved with conventional compression springs.
