ABSTRACT OF THE DISCLOSURE: A method for generating a holding force to retain a billet and die pressed against a die supported in a pressure chamber in a hydrostatic extrusion press comprising the steps of: supplying a pressure medium in the space at the end of the pressure chamber where the pressure-generating piston is inserted during the insertion of a billet therein while closing the pressure chamber; and creating the only holding force for the billet through the pressure drop of the pressure medium flow in a gap between the billet and a surrounding constructional element in the pressure chamber the gap having a radial dimension of less than lmm. The apparatus for generating such holding force comprises a pressure chamber including means for introducing a pressure medium therein; a die means for supporting a billet; die support means for supporting the die means and billet; the billet and the inner surface of the pressure chamber forming a gap therebetween enabling the escape of pressure medium therethrough during the insertion of a billet within the pressure chamber while the pressure chamber is being closed, the gap having a radial dimension of less than lmm.
