Can work hardening of the aluminum alloy stamping tool sheet material is gradually postage finally print shape in a succession of metal stamping operation. A piece of blank paper annealing starting material into at least the first precast block shape heating metal stamping tool formed between a precast block shape and subsequent preform shape annealing work. In one or more annealing precast block shape is gradually realize, and finally preform shape is cooling, if necessary, and postage to the final print shape between no heating metal stamping tool.
Automobile body panel and other sheet metal products have been made of a suitable steel alloy metal stamping process at ambient temperature. A steel plate edge blank are dependent on a binding mechanism, and attracted a blow to general metal concave the formation of a surface. Usually a steel alloy is available, it is appropriate formable and metal stretch into a Medium duty casters complex shape, such as body, no tear, wrinkling or destroy the table. The progress of a sequence of metal stamping, for example, puncture and cutting action may be successively in single executive steel plate to do a group, each step is in a few seconds.
