Zusammenfassung:A press tool for closed die forging a blank into a product is described. Said tool including upper and lower centre members and first and second side members. Said members define a cavity with the form of the product. In a two-step closed die forge process the blank is placed between said upper and lower centre members. The first and second side members are forced against the blank horizontally upsetting the outer edges of the blank. Then, the centre members are forced vertically into the blank, until the material in the blank has substantially filled the cavity.
