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