Abstract (en)
[origin: EP1097758A2] A flat blank (2) esp. a tailored blank, is subjected to e.g. a hydraulic or pneumatic medium (8) in a forming tool (3), to produce a pre-stretched semi-finished part. This part is subsequently formed to a finished part in a separate deep drawing tool. The die (5) of the forming tool has a smooth or profiled underside.
