Die

A die is a specialized tool component within a forming die set, typically consisting of upper and lower sections that work in conjunction to deform materials through mechanical force. It contains cavities, cutting edges, or forming surfaces that impart the desired shape onto workpieces during stamping, blanking, drawing, or bending operations. Dies are engineered to withstand high cyclic loads while maintaining dimensional accuracy over thousands of production cycles.

Operates by applying compressive force between mating die components (punch and die) to plastically deform or shear materials. The workpiece is positioned between the die sections, and when the press actuates, the punch descends into the die cavity, forcing the material to conform to the die's contours or cutting it along defined edges through shear stress exceeding the material's ultimate strength.
