Abstract (en)

Producing the castings involves the use of mold boxes (e.g. 1). Inlays (9) are heated after they have been placed in the lower box. The mold is then closed by putting the upper box in place. The molds (e.g. 2) are then cast. The inlays are heated to a temperature above the melting point of aluminum, and are still at a temperature in the region of the melting point when cast.

Abstract (de)

Zur Herstellung von Gußstücken aus Aluminium mit Einlagen aus einem anderen Werkstoff im Verbundguß werden Formsand über ein Modell in je einen von zwei die Form bildenden Formkasten verdichtet, in die Form wenigstens eines Formkastens die Einlagen und gegebenenfalls Formkerne eingelegt und beide Formkasten durch Zulegen zu einer Sandform geschlossen. Bei horizontaler Anordnung der Formkasten werden die Einlagen nach dem Einlegen in den offenen Unterkasten mittels einer externen Heizeinrichtung aufgeheizt, anschließend wird die Form durch Zulegen des Oberkastens geschlossen und daraufhin die Form mit der Aluminiumschmelze gefüllt, wobei die Einlagen soweit oberhalb der Solidustemperatur des Aluminiums aufgeheizt werden, daß ihre Temperatur beim Füllen der Form im Bereich der Solidustemperatur des Aluminiums liegt.
