The invention relates to a method for producing a metal foam body, according to which a molten material containing gas is prepared and said molten material is left to solidify, thus forming a metal foam body. The aim of the invention is to produce high-quality metal foam bodies with a desired shape, without requiring complex equipment and whilst reducing the safety risk for the operating personnel. To achieve this, the material used is fused under atmospheric pressure and gas is simultaneously and/or subsequently introduced into the molten metal. The latter is then poured into a mould and is left to solidify, whereby the ambient pressure is reduced at least temporarily.
L'invention concerne un procédé pour fabriquer un élément en mousse métallique, selon lequel on prépare une matière fondue chargée en gaz, laquelle se solidifie en formant un élément en mousse métallique. L'invention vise à fabriquer des éléments en mousse métallique de formes déterminées et de grande qualité sans appareillage trop complexe et en réduisant les risques en termes de sécurité du personnel. A cet effet, la matière employée est fondue sous pression atmosphérique et du gaz est introduit dans le métal liquide pendant et/ou après l'opération de fonte. Ensuite, le métal liquide est mis dans un moule et il se solidifie, la pression environnante étant réduite au moins de temps à autre.
