Fineblanking

Fineblanking is a specialty type of metal stamping that can achieve part characteristics such as flatness and a full sheared edge to a degree that is nearly impossible using a conventional metal cutting or punching process. Much like a cold extruding process, the part is pushed out of the strip while it is held very tightly between high-pressure holding plates. Fineblanking can be used on a variety of metals, including tool steel. It also is suitable for use on heavy metals up to 0.625 in. thick, even for making small holes.
