ABSTRACT OF THE DISCLOSURE An indirect extrusion process, and apparatus therefor, for producing an extrusion product from a hot metal billet. A press container is mounted to be substantially axially stationary during extrusion of a billet. A hot billet, a die and a pressure disc are loaded into the axial throughbore of the container so that the billet is sandwiched between the die and pressure disc, with the pressure disc having a maximum outer diameter between opposite radial faces which is slightly less than the diameter of the axial throughbore to define a diametrical clearance between the pressure disc and the press container. A bolster is located adjacent the pressure disc and is axially fixed to substantially prevent axial movement of the pressure disc in a direction toward the bolster during extrusion. The bolster exerts a relatively insignificant axial force against the container. An elongated stem having an axial passage is moved into the throughbore of the container to press the die toward the bolster, causing the billet to be extruded through the die to create an extrusion product which exits the container through the axial passage in the stem, while extrusion of the billet through the diametrical clearance between the pressure disc and the container is substantially avoided. - 48 -
