Compound Die
A die that performs multiple operations (e.g., blank and pierce) in a single press stroke at one station.
What it means on the floor
A compound die completes two or more cutting operations simultaneously at one station in a single stroke, producing a flat part with excellent flatness and hole-to-edge accuracy.
Because everything happens at once in one station, compound dies give superior dimensional control compared with progressive dies, but they are limited to relatively simple, flat parts.

Applying the term
Interpret Compound Die in the context of the drawing, governing standard, and customer requirement in front of you — the same word can carry different limits in design, quality, and production documents. Check whether a stated value is nominal, minimum, maximum, or reference-only, and whether it applies before forming, after forming, or after heat treatment.
