Abstract
A press for shaping a sheet metal blank in a cavity with a forming tool which determines the shape of the finished product. The sheet is pressed against the tool by a diaphragm which is influenced by a pressure medium on the side facing away from the cavity. The forming tool consists of an inexpensive casting material supported in a cup-shaped container. The space between the bottom and sides of the container and the bottom and sides of the cavity is filled with an elastic material.
