A method for casting an article composed of a foamed metal includes positioning a die (36) with a die cavity (38) above a bath (32) of a molten metal (34) and pressurizing the bath to cause the molten metal to fill the die cavity. A gas is then bubbled through the molten metal to form a foam. The foam is formed in the die cavity. Once the foam in the die cavity is solidified, the pressure in the bath is released and the formed article is removed. An apparatus for the method includes a die positioned above the bath, the die having a die cavity in fluid communication with the bath. The bath is provided with a pressurizing means (40) and a venting means (40) as well as a gas supply port (42) for forming the foam.

L'invention concerne un procédé de moulage d'un article constitué d'une mousse de métal. Ledit procédé consiste à placer une coquille pourvue d'une cavité au-dessus d'un bain de métal fondu et à mettre le bain sous pression, de manière à remplir ladite cavité avec le métal fondu. On fait alors barboter un gaz à travers le métal fondu pour former une mousse. La mousse est alors formée dans la cavité de la coquille. Une fois que la mousse de la cavité est solidifiée, la pression dans le bain est rela^chée et l'article formé est retiré. Un appareil conçu pour la mise en oeuvre de ce procédé comprend une coquille placée au-dessus du bain, ladite coquille comportant une cavité en communication fluidique avec le bain. Le bain est muni d'un dispositif de mise sous pression et d'un dispositif d'évacuation de gaz, ainsi que d'un orifice alimentation en gaz servant à former la mousse.
