Abstract

Ein Verfahren zur Herstellung von Formteilen aus pulvermetallurgisch hergestelltem Metallschaum, beispielsweise Aluminiumschaum, umfaßt das Aufschäumen eines kompaktierten Gemisches aus Metallpulver und gasabspaltendem Treibmittel als Ausgangsmaterial (Halbzeug) in einer beheizbaren Kammer (2). Die Menge des Ausgangsmaterials wird auf die Füllung in der Gußform (8) bzw. eines Gießvorganges abgestimmt. Der Inhalt der Kammer wird nach dem Aufschäumen in die Gußform gedrückt. Dabei kann ein Zeitpunkt gewählt werden, ab dem sich die Schaumbildung in der Gußform infolge restlicher Schäumkapazität fortsetzt. Dabei verhindert der Überdruck in den Poren des entstehenden Schaumes dessen Zusammendrücken. Die Gußform (8) kann eine unbeheizte nicht metallische Form, beispielsweise eine Sandform sein (Fig. 4).
