Abstract (en)

[origin: EP0804982A2] Production of moulded parts from foamed metal, e.g. aluminium is claimed, in which a powder metallurgical preform compacted from a mix of metal powder and foaming agent is foamed by heating in a chamber (2) separate from the mould (8), the volume of the fully foamed starting material corresponds to the mould volume, and the foamed metal content of the chamber (2) is injected into the mould (8), where foaming is preferably continued with the remaining foaming capacity until the mould (8) is completely filled. Process equipment is also claimed.
