Process for increasing the stiffness of a metal component at least in sections with a hollow space accessible from the outside useful in metal processing avoids the high cost and possible component damage of previous processes

摘要

Process for increasing the stiffness of a metal component at least in sections with a hollow space accessible from the outside involving introduction of a profiled part, e.g. a foamed plastic part, of dimensions adapted to those of the hollow space into the hollow space. An independent claim is included for a metal component with a hollow space accessible from the outside.
