    More on working for Herz

This is how you can benefit from Ätztechnik Herz

Low tool costs

In contour etched parts, optics are used instead of technical tools. These are ready for operation faster and are more cost-effective than metal punching tools for example.

Fully flexible when it comes to geometry

More complex means more expensive? Not with contour etched parts. They offer you new possibilities for complex structures –  for example because the metal is processed from both sides.

The most intricate structures with high precision

Ätztechnik Herz produces filigree and highly intricate structures that are not achievable with punching technology. The production process guarantees maximum precision to one hundredth of a millimeter.

Fast production

No time-consuming tool construction, efficient processes and what’s more extensive material storage. With Herz you get your finished product faster. With the Speedline service, in just 48 hours.

Burr-free and careful processing

Etching technology is a photochemical process. So the contour etched part is not impaired by burrs or deformations. A decisive advantage compared to mechanical processing.

Cleanliness in accordance with the German Association of the Automotive Industry regulation (VDA) 19

When etching metal, no metal particles are produced. In this way, Ätztechnik Herz meets the cleanliness requirements laid down in the German Association of the Automotive Industry’s regulation no. 19. Without the need for an additional cleaning process.

Etching process

Perfect process – perfect result
