By applying bends, 3-dimensional functional features can be realized on the component. Through the targeted application of bends, several functions can be realized in one component.

We are able to eliminate the need for additional components such as pins and pins by means of appropriately designed interpolations. Mechanical or sensory interrogations can be carried out if through-positions are designed as ramps or cams. Through holes can be used for positioning the component or for mounting with other components. Possible through holes up to 1.5 times the material thickness

Thanks to a targeted tool design, we are able to reduce the punch feed, which is normally 15-20% of the material thickness. This leads to an increase in the cut area. The material thickness can thus be reduced while maintaining the same surface pressure. The smallest possible indentation corresponds to 5% of the material thickness.

Burrs are reduced to a minimum during the punching process by embossing them in the tool. This eliminates subsequent deburring processes and shortens the production time. The maximum burr height must not exceed 0.05 mm.

Drawing enables high-precision metal forming. This process can be used to produce optimum guide lengths, precisely coordinated spacing and targeted clearances. These elements ensure stability, dimensional accuracy and enable complex shapes without additional components. The maximum draw-through height is 2.5 times the material thickness.

The targeted nesting of several components in the punching strip can achieve considerable material savings. The result is a targeted, sustainable use of material.

Thanks to our innovative tool systems, the base wall thickness can be thickened in a targeted manner. The base wall thickness can be thickened by up to 150%. This means you benefit from a sustainable use of materials.

Thanks to our innovative tool systems, the base wall thickness can be reduced in a targeted manner. The result of this is a targeted reduction in weight. Material thickness reductions of up to 80% are possible.

Thread forming in the tool enables the precise production of internal threads during the stamping process, eliminating the need for additional processing steps.
