High Pressure Die Casting

Method of producing precision castings with a high level of automation, and hence high productivity.  A permanent mould or die, made up of several parts has liquid metal injected into it, using a hydraulic piston, at pressures typically between 20 and 100MPa, depending on the alloy.  The mould abdorbs the stresses of injection, dissipates the heat, and ejects the casting before resetting for the next casting cycle.
