Abstract
A method of producing a tool or die from a model that includes producing a rigid mold from the model, forming a die shell of the model from a sheet of material in close conforming relationship over the rigid mold, and applying a reinforcing substrate to the die shell on a side of the die shell opposite that of the rigid mold. The applying step is performed while the die shell is still in close conforming relationship with the rigid mold, thereby forming the tool or die from the reinforcing substrate and die shell.
