Abstract

Semi-finished product foaming involves heating in a chamber using external radiation. A semi-finished product, consisting of metal powder and blowing agent powder and optionally joined to one or more cover layers, is foamed in a chamber by heating with external radiation. An Independent claim is also included for apparatus for carrying out the above process, comprising a chamber (10) with radiation transparent or translucent walls (20, 22, 24) and a chemically inert, radiation transparent or translucent protective layer (26, 28) enclosing the semi-finished product (12) to be foamed.
