Punching Stanze

A simple forming process, punching involves the use of a punch press to force a tool through a piece of metal to create a hole through shearing. It is a cost-effective method of creating holes in sheet materials in high-volume production processes.

Typically, a die is positioned on the opposite side of the steel from the punch. This supports the metal around the hole and helps to localize the shearing forces for a cleaner edge. The die and punch are often made of hardened steel or tungsten carbide.

Punching is often a high-speed process, and so requires an automated, real-time monitoring solution. This will inspect the steel to ensure effective punching, and detect any surface or edge defects caused by incorrect forming.
