High Pressure Die Casting enables economical quantity production of castings at a rapid rate. These castings can comprise of various holes, screw threads, recesses, and are characterized by a high dimensional accuracy and good surface finish. They enable good economy of metal and require little or no surface finishing. The principal on which pressure die casting is based, consists of forcing molten metal into a mold or the die, under considerable pressure. The machines which are used for this purpose operate on one or two systems:
Hot Chamber Machines (for metals with a low melting point)
