Springs are a common component within a range of different applications and their manufacture is a specialist process. Springs are made using wire, which is wound around a shaft in a process known as 'coiling' which gives the spring its shape. The wire can either be hot or cold during the coiling process, depending on the material and the type of spring being manufactured.
The coiling process can place stress upon the wire, meaning that secondary processes such as heat treatment and shot peening are often required to strengthen the spring. Springs are also regularly coated to provide resistance to corrosion.
Springs are commonly made from spring steel, although stainless steel, copper, carbon steel and alloy steel are also regularly used. It is possible for springs to be manufactured in both small and large volumes, although buyers can expect to pay more per part for small batches.

Lots of scope in terms of size and materials.
Specialist process which is usually offered by dedicated spring manufacturing companies, although some suppliers may be able to offer it as part of a turnkey service.
Secondary processes will often be needed to strengthen the spring after coiling.
