	THE PROCESSES


	Mays Pressure diecastings uses two production techniques depending primarily on the metal being cast.

Hot chamber high pressure diecasting
Used principally for casting components in zinc alloys with comparatively low melting points. The metal is melted in a crucible (integral with the diecasting process) and injected into the mould chambers by a force pump mechanism, partially submerged in the molten zinc alloy through a hollow tube (the gooseneck).

Cold chamber high pressure diecasting
Used for aluminium and its alloys which require a melting temperature too high for the hot chamber force pump mechanism to operate. The metal is melted in a totally separate furnace and transferred by ladle into an extension tube (shot sleeve) leading to the mould tool. From here it is forced into the die by a plunger.
