Hollow Embossing
Innovative forming of sheet metal and film components
Embossing (commonly referred to as stamping) opens up new possibilities for functionally integrated components with minimal material usage. In our pilot facilities, we work with you to develop robust forming processes for complex geometries. Ideal for industrial prototyping and the validation of new product designs.
How Embossing Works
The process is based on the interaction between the punch (male die) and the die. In this process, the film-like semi-finished product is plastically deformed between the two halves of the die by a combination of tensile and bending stresses. The punch plunges into the cavity of the die and draws the material into the depth along the defined tool radii. The resulting recesses form the channels for the media flow in the bipolar plate.
