Abstract

Die Erfindung betrifft ein Verfahren zur Herstellung von Gussteilen aus leichtmetallischen Legierungen, insbesondere unter Nutzung eines Druckgießverfahrens, wobei gewichtsreduzierte Gussteile hergestellt werden sollen. DOLLAR A Dies wird dadurch gelöst, dass nach der Füllung der Formkavität (2) mit Metallschmelze und Erstarrung einer Randschicht, in die verbliebene Schmelze ein Gas eingeleitet wird und die Schmelze unter Bildung eines Hohlraumes (5) aus der Formkavität (2) verdrängt wird.The invention relates to a method for the production of castings from light metal alloys, in particular using a die casting process, wherein weight-reduced castings are to be produced. DOLLAR A This is achieved in that after the filling of the mold cavity (2) with molten metal and solidification of an edge layer, in the remaining melt, a gas is introduced and the melt is displaced to form a cavity (5) from the mold cavity (2).
