[origin: WO2006056410A1] The invention relates to an improved vacuum die-casting method, in particular for metals and metal alloys which contain Al, Mg, Zn and Cu. According to the invention, a vacuum in the casting chamber and die cavity chamber is produced in several phases of the die-casting process in order to improve the quality of the component. The invention also relates to the uses of the novel method for cold chamber diecasting and also for warm chamber die-casting.
