摘要： The invention relates to a method for simultaneously producing at least two separate workpieces (6, 7) by means of internal high pressure forming. According to said method, a blank is inserted into a form tool (2), the inner wall (3) of said blank comprising at least one dividing gap (8) which is respectively arranged between two negative moulds (4, 5), extends over the entire circumference of the workpieces (6, 7) and is defined by two interspaced, free cutting edges (9, 10). During the forming, the blank penetrates the region of the at least one dividing gap (8) such that the cutting edges (9, 10) respectively cut out a section (15) between two workpieces (6, 7).
