摘要

A process for producing a lightweight molded part, comprising introducing a gas into a particle-containing molten metal to produce a metal foam having voids with a monomodal distribution of their dimensions, introducing the metal foam into a casting die, and compressing it therein essentially under all-round pressure; and the molded part made by this process.
