The most common processes for manufacturing technical flat springs are stamping or stamping and bending, lasering or laser cutting. Anyone who relies on the quality and functionality of individual shaped springs also trusts the manufacturer's competence in the shaping production methods. This article explains what plays a role in this.
Whether in medical or electrical engineering, mechanical or aircraft construction or in precision engineering: stamped and bent parts in the form of flat springs are among the most commonly used components across all industries. The range extends from spring clamps and spring clips to simpler molded metal parts, to retaining springs, spring contacts and even EMC contact springs.
In "sensitive" areas of application such as medical laboratories or in electrical engineering, there are special requirements for the smoothness and hardness of the surface or for the electrical conductivity, which are already decisive when selecting the material.
In other areas, insensitivity to temperature or extremely long-term use play a role. In order to meet the requirements, there is a variety of materials and material processing methods, which still provide an efficient solution for every individual problem.
Almost all qualities play a role in the concert of material materials: flat and shaped springs are lasered, punched, bent, screwed, folded, welded or riveted from flat steel, stainless steel or flat strip and made suitable for special purposes with special alloys.
With large quantities, stamped and bent parts convince with their cost-efficient production. But even in smaller batch sizes, they impress with their inexhaustible formability, which is particularly important for individual technical springs.
Even with complicated bending geometries on several levels, stamped and bent parts prove their worth, which can also be precisely adapted to individual requirements through subsequent surface treatments. The machinery used works with high precision, both in terms of the complicated shape and with regard to the treatments or alloys of the surface for specific applications.
Medical cleanliness, special resilience, electrical conductivity or special spring characteristics are examples of a precise solution to a demanding task.
Surface treatments such as burnishing, gold plating or galvanizing are further options from an almost inexhaustible portfolio of possibilities. This is supported by the effective options that result from the use of the most modern lasers and laser cutting machines. Precision and complete freedom of contour are the keywords here.
The complexity of the different processes makes it clear that only tried-and-tested manufacturers who have "all the experience" can deliver the top quality that is required to achieve a big effect with small parts. Schaaf has many years of experience and the expertise to use state-of-the-art machinery in all trades cost-effectively and efficiently.
