Beschreibung
Zusammenfassung:	A compound billet for extrusion by isostatic liquid pressure which has a core and a casing with a gap therebetween is produced by applying a sealing ring with greater thickness than the gap between the core and the casing around the rear end of the core, then inserting the core into the casing, and pressing the sealing ring to stick in the gap between the core and the casing so that the sealing ring and/or the casing are deformed. The rear end of the casing is beveled inwardly.
