Each leaf spring is unique

Examples of individually manufactured leaf springs

Typical applications of a leaf spring

A leaf spring creates the connection between components that require different forces: for example, holding, pulling, pushing or clamping. In addition, leaf springs also create electrical contacts as spring contacts. Since these functions can overlap - the spring in a normal flashlight holds the battery and closes the circuit at the same time - it is difficult to determine clear assignments.

 

According to the different functions, general 4 categories of leaf springs differentiate:

flat springs & shaped springs / Steel springs / Spring clips / contact springs

Customised solutions for leaf springs

Our customers often have special requirements for leaf springs. We offer customised solutions that are precisely tailored to your needs. We are also happy to support you in finding the optimum solution for your requirements. Simply contact us if you require specific leaf spring designs - we look forward to receiving your enquiry!

 

Do you already have an idea of what your leaf spring should look like, or do you already have a sketch or CAD drawing? You know what you need and we'll take care of the rest. Send us your drawing or a sample and we will optimise the right leaf spring for you. Together we will select the right material, the right production technology and the surface finish.

No two leaf springs are the same

Although it may not be obvious at first glance, the leaf spring is the result of complex calculations and careful material selection using extensive technical expertise. The following are taken into account Requirements in terms of weight, size and electrical conductivity as well as, for example, an exact balance of forcesto hold components in a certain position. It is always a special geometry that takes the complex requirement profile into account.

As leaf springs are generally used in industrial and commercial applications, particularly high demands are placed on their robustness, reliability and durability. This problem is also taken into account in the development of a technical spring.

Schaaf tests leaf springs 100,000 times in individual cases

Blood collection tubes are an example of maximum robustness in a sensitive area. As different in diameter as the ampoules and tubes are, they all have to fit easily into trays with compartments of the same size. A tube must neither wobble nor be crooked, even if it is already on its third label, which is quickly applied by hand.

The special retaining spring from Schaaf is tested for these requirements with 100,000 strokes!

Universal and customised - leaf springs from Schaaf

Whether it's a special option for cost-effective wheel suspension in a commercial vehicle or a special spring geometry for PCB testing, the high-quality solution usually comes from our company. We develop customised products together with our customers, die mit einem der modernsten Maschinenparks realisiert werden. Dabei werden unterschiedlichste Werkstoffe wie Federstahl, Stahl, Edelstahl und NE-Metalle verarbeitet. Die Techniken, die wir bei unserer Qualitätsproduktion einsetzen, reichen von Stanzen und Prägen über Schleifen bis zu Lasern. In der Oberflächentechnik können Sie zwischen unterschiedlichen Optionen für die Bearbeitung unserer maßgeschneiderten Blattfedern wählen: Das Phosphatieren steht Ihnen ebenso zur Auswahl wie das Gleitschleifen (Trowalisieren®), Verzinken, Lackieren und Brünieren. Am Ende steht immer eines: Die hochwertige, zuverlässige und nachhaltige Lösung Ihres Problems!
