Specification:‘Fielding’ 50/30 MKII Hydrostatic Extrusion Press
Description:The MKII machine incorporates a self-contained intensifier unit complete with its own pump equipment, supply tanks, piping and controls and will deliver hydrostatic fluid at 50 tons/sq. in. (78.7 kg./sq. mm).  The extrusion chamber is normally mounted alongside the intensifier unit as shown on our Drg. No. 114/67/E (currently at Rhodes Interform).  This allows the customer to install an additional extrusion chamber, if required, which can be isolated from the intensifier unit by high pressure shut-off valves.
With the standard extrusion chamber, billets of 4″ (100 mm) dia. x 9″ (230mm) long may be simply hydrostatically extruded into atmosphere.  Alternatively, using differential extrusion tubes, also available, brittle material may be extruded into a pressure behind the die or simple hydrostatic extrusion of long billets may be carried out. (Billets 1 1/2″ dia. x 10′ 0″ long).
Standard tooling equipment is available for use in conjunction with this intensifier unit but this may be re-designed to meet customers own requirements, at a revised cost.
In addition to the above tooling equipment, we are able to supply a small tooling unit to fit inside the 4 3/8″ dia. x 10″ long chamber, that will allow extrusion pressures of 200 tons/sq. in. (315 kg/ to be reached.  The billet size that can be accommodated within this tool set is approximately 5/8″ (16 mm.) dia. x 1 1/4″ (32 mm.) long.
Semi-continuous and augmented tool sets may also be used with the intensifier unit, but at this stage they do not form part of our standard tooling.
