Abstract

A tool and die set and related method of use of the tool and die set in a press for the compaction of a powder metal into a preform involves an uneven amount of positional deflection of at least two lower or upper tool members. This asymmetrical elastic response under load may help to eliminate cracking of the part after the compressive load is removed.
