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 mold and is left to solidify, whereby the
ambient pressure is reduced at least temporarily.
