FORMED MATERIAL MANUFACTURING METHOD AND FORMED MATERIAL

摘要

A molded material is manufactured by molding processing including at least one time drawing-out processing, and at least one time drawing processing performed after the drawing-out processing. A punch (31) used for the drawing-out processing has a wider width on the back end side than that on the front end side. Ironing processing is performed on a region corresponding to a flange part of a starting material metal plate by pushing the starting material metal plate, together with the punch (31), into a push-in hole (30a).
