Abstract

Die Erfindung betrifft ein Verfahren zum Feingießen eines metallischen Formteiles oder mehrerer vorzugsweise dimensionsgleicher metallischer Formteile, bei welchem eine metallische Schmelze in eine keramische Gießform abgegossen wird, wonach die metallische Schmelze erstarren gelassen wird. Um insbesondere auch bei einer verstärkten Abkühlung der Schmelze bei der Erstarrung ein lunkerfreies Gefüge zu erhalten, ist erfindungsgemäß vorgeschlagen, dass die abgegossene Schmelze unter Ausübung eines Druckes auf die Schmelze verstärkt abgekühlt wird, wobei Druckausübung und verstärktes Abkühlen zumindest bis zur Formbeständigkeit des erstarrenden Formteiles bzw. der Formteile aufrechterhalten werden.The invention relates to a method for investment casting of a metallic molded part or more preferably dimensionally similar metallic moldings, in which a metallic melt is poured into a ceramic mold, after which the metallic melt is allowed to solidify. In order to obtain a void-free structure especially in the case of increased cooling of the melt during solidification, it is proposed according to the invention that the cast-off melt be intensively cooled while exerting a pressure on the melt, pressure being exerted and increased cooling at least until the dimensional stability of the solidifying molded part resp The moldings are maintained.

Weiter betrifft die Erfindung eine Vorrichtung zum Feingießen eines metallischen Formteiles oder mehrerer dimensionsgleicher metallischer Formteile.
