Process for producing shaped metal parts |
摘要 |
The invention relates to a process for producing shaped metal parts, in particular reduced-weight shaped parts made from metallic materials. In this process, a metal body with a surface which is closed on all sides and a hollow structure in the interior is placed into a die as a core and is then surrounded with a metal melt by casting. The surface region of the metal body has a mean density which is higher than the interior of the metal body by a factor of 1.5 to 20.
