ABSTRACT:
In the hydrostatic extrusion of tubes in a press which has a pressure chamber containing a high pressure cylinder, a pressure generating portion insertable into the cylinder, a die arranged in the cylinder and a mandrel axially fixed in relation to the die and composed of a carrier portion and a tip, and in which the tip forms with the opening in the die a gap in which a tubular billet is shaped into a tube by hydrostatic extrusion, in connection with the insertion of the tubular billet, a seal is produced initially between the mandrel and the hole in the billet at a point between the front part of the mandrel carrier and the hollow wall of the billet. This may be done by producing a constriction of the front end of the hole in the billet before the mandrel is inserted therein or by upsetting the billet against the die.
