ABSTRACT:
A method of die forming using an elastically deformable die is characterized by using a die provided in advance with a prescribed pattern of thickness variation, allowing the die to be elastically deformed by the pressure it receives from the material being formed during the forming operation, and forming the material to the configuration resulting from the deformation.
