From punching and lasering flat springs

The most common methods for manufacturing technical flat springs are stamping or stamping and bending as well as laser cutting. Anyone who relies on the quality and functionality of individual moulded springs also trusts the manufacturer's expertise in the shaping production methods. This article provides information on what plays a role here.

Whether in medical or electrical engineering, mechanical engineering, aircraft construction or precision mechanics: across all industries Stamped-bent parts in the form of flat springs are among the most commonly used components. The range extends from spring clips and spring clips to simpler moulded metal parts, retaining springs, spring contacts and even EMC contact springs.

In "sensitive" areas of application such as medical laboratories or in electrotechnical applications, there are special requirements for the smoothness and hardness of the surface or for electrical conductivity, which are already decisive when selecting the material.

In other areas, temperature insensitivity or extremely high continuous use play a role. In order to fulfil these requirements, there is a Variety of materials and material processing methodswhich still provides an efficient solution to every individual problem.

Almost all qualities play a part in the concert of materials: From Flat steel, stainless steel or flat strip become Flat and moulded springs Laser-cut, punched, bent, screwed, bevelled, welded or riveted and made suitable for special purposes with special alloys.

For high quantities, stamped-bent parts impress with their Cost-efficient production. But they are also convincing in smaller batch sizes thanks to their inexhaustible mouldability, which can be used for individual technical springs is particularly in demand.

Even with complicated bending geometries on several levels, the Stamped and bent partswhich can also be precisely customised to individual requirements through subsequent surface treatments. The machinery used is highly precise, both in terms of the complex moulding and with regard to the surface treatments or alloys for specific applications.

Medical purity, special resistance, electrical conductivity or a special suspension characteristic are examples of a precise solution to this demanding task.

Surface treatments such as burnishing, gilding or galvanising are further options from an almost inexhaustible portfolio of possibilities. These are complemented by the effective options that result from the use of state-of-the-art lasers and laser cutting machines. Precision and complete freedom from contours are the keywords here.

The complexity of the different processes makes it clear that only manufacturers who have been tried and tested in practice and who have "learnt the ropes" can deliver the top quality that is required to work with Small parts have a big effect to achieve. Schaaf has many years of experience and the expertise to utilise state-of-the-art machinery cost-effectively and efficiently in all trades.
