Walzenprägen

Walzenprägen is a metal forming process used to impart a decorative or functional pattern onto a metal surface. It involves passing a sheet or strip of metal through a pair of rotating rollers, at least one of which is engraved with the desired pattern. As the metal passes between the rollers, the engraved pattern is pressed into its surface, creating a raised or recessed design. This technique is distinct from calendering, which typically uses smooth rollers to control thickness or achieve a smooth finish.

The depth and clarity of the impression depend on several factors, including the material's malleability, the pressure applied by the rollers, and the precision of the engraved die. Walzenprägen can be applied to a variety of metals, such as steel, aluminum, brass, and copper, and is often used for decorative purposes on products like packaging, architectural elements, and consumer goods. Functionally, it can be used to improve grip, enhance structural rigidity, or create specific surface textures for applications like flooring or automotive interiors. The process is highly repeatable and efficient, making it suitable for high-volume production.
