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.
Claims5
A die forming method comprising the steps of:
- using an elastically deformable die having a flat surface which contacts a material being formed, said die being provided with local variations in thickness so that said flat surface is formed with prescribed concavities and convexities under elastic deformation caused by pressure from the material being formed during a forming operation;
- carrying out the forming operation and thereby causing the material to contact said flat surface under a prescribed pressure;
- and
- allowing said prescribed concavities and convexities to be formed on the flat surface off the die under the pressure from the material, whereby the material is formed with the concavities and convexities.
