Patent number: 7137433Abstract: A lightweight part and process and device of making the same, the lightweight part including an inner core including a metal foam. A dense core surface layer is metallically joined to the inner core. An outer wall includes an essentially pore-free cast metal layer that is at least one of positively engaged with the dense core surface layer and surrounding the inner core, and metallically joined to the dense core surface layer and surrounding the inner core. The process includes creating a core part by forming the dense core surface layer, forming the inner core of a metal foam, and metallically joining together the inner core and the dense core surface layer. The process further includes creating a finished part by positioning the core part in a casting mold, feeding a melt material into the casting mold, and allowing the melt material to solidify so as to form the outer wall.Type: GrantFiled: April 16, 2003Date of Patent: November 21, 2006Assignee: Huette Klein-Reichenbach Gesellschaft m.b.H.Inventors: Franz Dobesberger, Herbert Flankl, Dietmar Leitlmeier, Alois Birgmann
