Abstract (en)
[origin: EP1147833A2] A process for deep drawing planar sheet metal, to produce mouldings with local contours with a small radius over the base area, comprises fixing the edges of the sheet metal and forming the sheet metal using a stamper which acts against a fluid work medium. The sheet metal is formed against local mould contours which are fixed and which are elastic.
