Definitions
- indirect squeeze casting processes use a closed die to define the casting cavity. Opposing die halves are locked together rigidly by hydraulic cylinders and large toggles during the injection of metal from the shot sleeve and during the metal pressurisation period from the plunger. The only moving part of the equipment during casting is the plunger, which moves to inject metal into the fixed volume die cavity. Side cores may be used in the die to increase the complexity of the casting shape. Although the external form of the cast article may be accurately controlled, indirect squeeze castings may not be one hundred percent dense due to the presence of microporosity, particularly in regions of the casting remote from the plunger.
- the lower die part is encased in a steel bolster.
- Metering of the correct amount of liquid metal into the mould is effected through having the top half of the die 6 situated within the lower half of the die 5 so defining the mould cavity 11 but raised on, preferably adjustable, compressible separators 19 by an amount which just compensates for the volume contraction of the liquid metal on solidification and compaction by the squeezing forces of the hydraulic press 1.
