Abstract: A method for producing a composite structure in which a foamed metal core (1) is surrounded with a metal body (3). The method includes the following steps: a) producing a foamed metal core (1) with an essentially closed surface; b) introducing the foamed metal core (1) into a pressure die-casting mold; c) filling the pressure die-casting mold at a first casting pressure (p1); d) reducing the first casting pressure (p1) before the pressure die-casting mold has been filled; e) filling the pressure die-casting mold entirely, the first casting pressure (p1) being reduced to zero or almost zero; and f) applying a second casting pressure (p2) and maintaining the second casting pressure for a predetermined holding period.
