Abstract
1428444 Extruding ALLMANNA SVENSKA ELEKTRISKA AB 11 June 1973 [12 June 1972] 27672/73 Heading B3P The description is identical with Specification 1,428,443 but the invention relates to a hydrostatic extrusion method using a press with an axially movable high-pressure cylinder 5, a tubular pressure generating punch 10, and a rod 14a, 14b passing through the punch and acting as a mandrel, wherein the billet 22 to be extruded has a smaller inner dimension 36 at its end nearer the die 21 than the dimension of the rod. The rod thus cannot move through the billet and pushes the billet and die gainst the crosshead 2 of the press stand ready for the cylinder 5 to be moved thereover.
