Abstract: In manufacturing a rod or wire of compound material from a core of aluminum or aluminum alloy and a casing of copper or copper alloy by hydrostatic extrusion, a billet is used in which the core has a smaller external diameter than the internal diameter of the casing, so as to provide clearance therebetween sufficient that at least most damage to the casing during soft-annealing and handling will not be of sufficient extent to prevent the insertion of the core into a casing. An internal space is provided at the rear of the billet to collect the air present in the gap between the core and the casing as it is displaced when the core and casing are pressed into contact with each other.

Abstract: A high pressure seal for sealing between a movable piston and the wall of a pressure chamber is formed of two rings which have oppositely sloping inward directions forming a V within which a resilient sealing strip fits. The two rings have sloping mating faces directed inwardly towards the axis of the cylinder.

Abstract: A wire or rod having an aluminum or aluminum alloy core and a copper or copper alloy casing is produced by hydrostatic extrusion of a compound billet through a die having a conical inlet with an outerpart with a cone angle between 70* and 115* and an inner part with a cone angle between 130* and 150*, the diameter of the inner part being substantially equal to the greatest dimension of the die opening.

Abstract: A press for hydrostatic extrusion of tubes includes a high pressure cylinder axially displaceable in a press stand with a die insertable into the cylinder and a pressure generating punch insertable into the cylinder to generate the pressure for extrusion. A mandrel is carried by a rod which passes through the pressure generating punch. Seals are provided between the mandrel and the pressure generating punch and between the pressure generating punch and the pressure cylinder. These seals are so located that during the actual extrusion they are arranged in the same transverse plane.

Abstract: A billet, formed of a hardenable aluminium alloy containing substantial amounts of undissolved constituents other than aluminium and which has not been solution-heat treated, is hydrostatically extruded through a die at such a rate that, considering the reduction in cross-section and the rate of extrusion, the extruded product attains a temperature greater than the dissolving temperature of the constituents. The temperature of the extruded product is kept at substantially the dissolving temperature for a time sufficient to product dissolution and is thereafter rapidly cooled.

Abstract: A press for hydrostatic extrusion of tubes has a pressure chamber containing a pressure generating fluid and a spacer element arranged in the cylinder with a mandrel axially fixed at its inner end by the spacer tube. The mandrel has a point part cooperating with the die in the cylinder. This point part of the die has a smaller cross-section than the rear part of the die, which rear part is secured to a support from which it is separate. The joint between the support and the inner end of the die is sealed. The pressure exerted by the pressure fluid on the larger part of the mandrel in a direction away from the die is greater than the frictional force between the billet being extruded and the point of the mandrel.

Abstract: In manufacturing tubes of compound material by hydrostatic extrusion through a die, the front end of the billet is formed with a taper to fit the conical inlet of the die. The mating line between the lower ends of the core and the casing is within the die, so that when extrusion starts only the casing is in contact with the die and only the core with the mandrel. This prevents any possible entry of pressure fluid between the core and the casing.

Abstract: A press for hydrostatic extrusion of tubes includes a press stand with a pressure cylinder movable therein to engage over a die supported by the press stand, and a pressure-generating punch movable in the other end of the cylinder. A sleeve slidable in the cylinder supports a mandrel which can engage through an annular billet into the die opening. A billet holder is slidable in the sleeve, the mandrel passing through it. The billet holder is so constructed that pressure fluid can pass from one side of it to the other.

Abstract: For manufacturing rod, wire or tube-shaped products of compound material, a billet which is composed of a core and a casing, of different materials, selected from aluminum and cooper and their alloys, is hydrostatically extruded through a die. Either the core or the casing or both at their facing surfaces have an amount of oxides thereon which is substantially less than the amount required to form a continuous layer of molecular thickness when the billet is extruded with a selected extrusion ratio.
