Abstract
The invention relates to a process for producing metal/metal foam composite components, wherein a flat or shaped metal part is introduced into the cavity of a die, the cavity being at least partially delimited by the metal part, and then a mixture comprising a metal melt and a blowing agent which is solid at room temperature is introduced into the cavity, where it is foamed.
Claims16
A process for producing a metal/metal foam composite component, wherein said metal/metal foam composite component comprises a flat or shaped metal part and a metal foam, in a high pressure injection die-casting machine comprising a die cavity, said method comprises placing the flat or shaped metal part into the die cavity so that the flat or shaped metal part at least partially delimits the die cavity;
- and forming a mixture comprising a metal melt and a blowing agent, which is solid at room temperature, in the die cavity, where the foaming takes place.
