METHOD FOR QUALIFYING DIE MATERIAL AND TESTING DIES

A method (10) for acquiring material for use within a die and for determining whether a die has certain characteristics which would allow the die to have a relatively long operating life. The method (10) requires that a suppler of a die provide certain material which is analyzed to determine whether the supplied material has a certain toughness. If the material has the requisite toughness, a material signature is created and used to evaluate further materials and dies produced and/or provided by the supplier.
