Abstract
A forming press for forming a sheet-like blank has a first thermally insulated frame part having a die with a negative engraving and a second thermally insulated frame part defining a chamber and having a punch movably disposed in the chamber. The sheet-like blank rests in a sealing manner on the second frame part and covers the punch so as to define a pressure chamber with the punch therein. A pressure generator provides a pressurized gas to the pressure chamber during a forming process.
