Compound dies are advanced tooling systems that perform multiple operations—typically blanking and piercing—in a single press stroke at the same die station. This results in superior dimensional accuracy, flatness, and clean part edges, making them ideal for disc-shaped, flat, or symmetric components requiring high repeatability.

Unlike progressive dies where the workpiece moves through multiple stations, compound dies perform all operations at a single station. This makes them exceptionally efficient for certain types of parts where dimensional relationships between features are critical.
