Production processes

Functionally optimized springs due to thermal processing, pre-setting, grinding and surface treatment.


Coiling

The spring wire is wound through a cold winding process. It is pulled forward to pins, which, according to their settings and their positions, define the outer diameter of the spring.

Meanwhile, the pitch (distance between successive coils) is formed by the lifting wedge, a steering mechanism. Finally, the wire is cut to the predetermined length.

Thermal process

The winding creates anxiety within the material. To alleviate this tendency and allow the steel to maintain its characteristic elasticity, the springs must be tempered by heat treatment. Depending on the shape of the spring and the material we use different ovens to achieve the best possible product quality.

Composition

When the material is stressed above its elastic limit, the spring may be plastic deformed without returning to its original length after its release. This leads to a reduction in strength. To permanently stabilize the desired length and spring pitch, it is compressed for a specified period of time. This helps to avoid loss of length and strength when the spring is exposed to stress above its elastic limit in later operation.

Grinding

The ends of the compression spring must be aligned with adjacent sections to ensure optimum power transmission. The ground ends and the closed coils as ends (i.e., the reduced coil step) provide a larger contact surface at right angles to the spring axis. We use different grinding machines for different spring shapes and wire diameter.

Our springs are characterizedby lower production tolerances due to:


Therefore, we are adding the "Factory for Precision-Made Springs" as a subtitle to our company name.

We collaborate with technical universities in different research and development projects.

High precision springs are used inter alia as contact elements, energy storage elements, vibration elements, damping elements or bearing elements in many industries such as:
