  • Method of producing molded bodies of a metal foam
    Patent number: 5865237
    Abstract: A method of making castings of metal foam in which compacts of the metal, e.g. aluminum, and a gas-producing foaming agent are heated in a chamber from which the foaming mass is driven completely into the mold cavity so that some residual foaming can complete the distribution of the foam in the mold cavity. The volume of the compacts is selected such that upon complete foaming, it will fill the mold cavity.
