Abstract: A press for the hydrostatic extrusion of long billets has a stand with a pressure generating chamber and a pressure generating plunger insertable in the pressure generating chamber to generate high pressure in a pressure medium contained therein. A pressure chamber is arranged in line and communicates with the pressure generating chamber. A stationary support table is provided to take up axial forces on a die, and is spaced from the opening of the pressure chamber so that a die can be inserted into alignment with the opening of the pressure chamber. The support table contains a piston which is movable in the direction of the pressure chamber and on which the die support is carried for movement of the die into the opening of the pressure chamber opening.
