Abstract

The semi-finished car part (1), consisting of porous metallic foam material (2) has the same thickness in all areas. With a specific device (17), the part is provided by pressure with an indent (15) which later will serve as the joint area for the attachment of further body parts. The thinner area (15) can be of various shapes depending on its purpose.
