Countergravity casting of metals and metal alloys provides for melting of the metallic material under subambient pressure, evacuation of a gas permeable or impermeable mold (15) under subambient pressure, and controlled, rapid filling of the mold (15) while it is maintained under the subambient pressure by applying gas pressure locally on the molten metallic material in a sealed space defined by engagement of a mold base (13) and a melting vessel with a seal therebetween. The gas pressure applied locally in the sealed space establishes a differential pressure on the molten metallic material to force it upwardly through the fill tube (16) into the mold (15).

Le coulage en contre-gravité de métaux et d'alliages métalliques permet d'assurer une fusion de la matière métallique à une pression inférieure à l'atmosphère, l'évacuation de l'air d'un moule (15) perméable ou imperméable aux gaz à une pression inférieure à l'atmosphère et un remplissage rapide et contrôlé du moule (15) à la pression inférieure à l'atmosphère, maintenue par l'application locale d'une pression gazeuse sur la matière métallique en fusion, dans un espace hermétique défini par une base (13) de moule en contact avec un récipient de fusion, un joint séparant ces deux éléments. La pression gazeuse appliquée localement dans l'espace hermétique établit un différentiel de pression sur la matière métallique en fusion qui la pousse vers le haut à travers un tuyau (16) de remplissage dans le moule (15).
