Abstract
A method for die casting a metal alloy in a cavity, implementing a mold comprising an induction heater to heat the molding surfaces of the cavity. The cavity is filled with the metal alloy by injection and preheated to a nominal preheating temperature T1. The metal in the cavity is solidified. The mold is opened and the part is ejected therefrom. The molding surfaces of the cavity are heated by induction while the part is no longer in contact with said surfaces. The molding surfaces of the cavity are sprayed, the mold being opened, by a release agent. The mold is closed and the cavity is heated the temperature T1.
