Steel-rule-die blanking is a shearing process in which a punch and die set is
used to cut a part from stock material. The die consists of a thin strip
of steel (formed to the contour of the part) supported on its edge. The
punch is a flat surface made of steel, wood, or rubber.
Process Characteristics
Uses thin strip steel knives as shearing dies
Is often limited to short production runs
Is predominantly used for nonmetallic material
Is used for nonmetallics and thin gage to half hard
sheet metals
Reduces die design and fabrication costs over
conventional dies
