ABSTRACT:
A method of die casting high melting point metals such as ferrous metals by introducing a shot of molten metal under pressure into a die cavity in which the molten metal for each shot is produced by melting a slug in an induction furnace and wherein the melting is done in two stages in the first stage there being applied a relatively great heat input to the charge at a relatively high rate and in the second stage there being applied a reduced heat input to the charge at a reduced rate.
