<p>A metal foam molding, has one or more channels for temperature control fluid passage. An Independent claim is also included for production of a molded part having one or more regions (9) in which a metal foam material is foamed after molding of the molded part (30a), the metal foam material being internally temperature controlled by a temperature control fluid during foaming. Preferred Features: The or each channel (18) may be perforated and may be connected in thermally conductive contact with a temperature control sheet (19d) having closely adjacent pockets. The metal foam molded part (30a) includes a structural part (3) of a material which ensures structural stability before foaming. Each channel may comprise an outer flow channel (18) surrounding an inner flow channel which terminates in front of a closed end of the outer channel, the inner flow channel having a spiral tape winding. The inner and outer channels consist of a heat and pressure resistant composite fiber material which includes highly thermally conductive fibers. After foaming of the metal foam material, the or each channel is filled with plastic.</p> |
