Steel-rule-die blanking
Steel-rule-die blanking is a stamping process in which a
custom tool
is used to cut a part from sheet material.
The tool consists of a thin strip of steel formed to the contour of the
part. The tool is a flat surface made of steel, wood, or rubber. As the press closes, the steel rule penetrates the workpiece causing the workpiece to shear at the point where the steel rule
meets the material.
Possible shapes
2D shapes including cutouts.
Steel-rule-die blanking Guidelines
Minimize number of cutouts. Avoid intricate shapes.

Example parts
Gaskets, plates.
Advantages of Steel-rule-die blanking
Reduces die design and fabrication costs over conventional dies.
