METHODS FOR MANUFACTURING FLANGED ARTICLE

摘要

A method for manufacturing a work (W) having a peripheral flange (ml) by pressing a sheet material (M) including half die cutting the material so as to simultaneously form inner and outer circumferential surface of the peripheral flange (ml) while the peripheral flange is simultaneously subjected to isostatic pressures that are directed from the flange inner surface to the flange outer surface or from the flange outer surface to the flange inner surface.
