The invention concerns a process and apparatus for continuous hydrostatic extrusion wherein the pressure of the hydrostatic fluid is used to apply the blank to be extruded firmly against the walls or the bottom of a groove provided in a rotor, in such a way that the blank is entrained by the rotor without slipping to an extrusion chamber from which the blank is spontaneously extruded through a die. The invention finds use in particular for continuous extrusion of metal and alloys, including those which have a low degree of ductility.
