What are the advantages and disadvantages of compound dies?

Compound dies are commonly run as single hit dies but can be run continuously with a feeder provided the part can be removed in a timely manner.

The advantages of building a compound die are;

1) Requires minimal space in the press.

2) Leaves all burrs in one direction.

3) Superior accuracy between holes and trim edges.

4) More economical to build than a progressive die.

A disadvantage of building a compound blank die is the limitedspace which ends to leave die components thin and weak. This concentrates the load and shock on punches and matrixes resultingin tooling failures.
