Pressure Diecasting

Abstract

Pressure diecasting differs from gravity diecasting in that a positive pressure is maintained upon the metal in the mould while solidification is taking place; in most of the various pressure diecasting techniques an applied pressure is also employed to inject the metal into the mould, but this is not universally the case. Of the ten distinct techniques listed in Table 1, three are in general commercial use and, together, account for more than 95% of world diecasting production.
