Fine Blanking / Blanking / Stamping - voestalpine HPM Division

Fine Blanking is used in many industries where precision parts need to be produced with high efficiency. Especially the automotive industry uses this process to produce parts like seat belts, brake systems or airbags.

This is an extremely challenging application as often high strength materials need to be processed and therefore often only powder metallurgically produced steels can ensure the required tolerances. It is important to understand in detail the customer requirements and hence often an intensive dialog is needed to select the optimal tooling materials and the most suitable heat treatment and PVD-coatings. We believe that in fine blanking, it is crucial to rely on the right partner with extensive process knowledge. Customers face significant challenges as these parts are very complex. Therefore, it is important to avoid downtime and damage. Overall, fine blanking ensures higher productivity.

The most important feature of fine blanking is the smooth cut edges and higher precision of the finished part. The advantages are a long product lifetime and that no additional finishing is required, which is not the case with normal stamped parts. To ensure quality and precision, we recommend using a high-performance tool steel as well as PVD coating. In addition, the choice of the right steel is a decisive factor in reducing maintenance costs.
