Abstract

A system for annealing a formable panel includes a stamping press configured to pre-form the panel using a first die and a second die. The system also includes a transfer device configured to engage the pre-formed panel and transfer the panel from the stamping press. The transfer device includes a heating element configured to anneal the pre-formed panel. The heating element anneals the pre-formed panel in the stamping press after the first die is disengaged from the panel and while the panel is being supported by the second die. A method of processing a formable panel and a method of processing a pre-formed panel in a multi-stage stamping operation, each using the system, are also disclosed.
