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. This abstract is neither intended to define the invention disclosed in this specification nor intended to limit the scope of the invention in any way.

The present application claims priority under 35 U.S.C. §119 of Austrian Patent Application No. A 610/2002, filed on Apr. 19, 2002, the disclosure of which is expressly incorporated by reference herein in its entirety.
1. Field of the Invention
The invention relates to a lightweight part. The invention also relates to a process and a device for producing the lightweight part.
The present invention is further described in the detailed description which follows, in reference to the noted plurality of drawings by way of non-limiting exemplary embodiments of the present invention, in which like reference numerals represent similar parts throughout the several views of the drawings, and wherein:
FIG. 1 shows a lightweight part according to the invention;
FIG. 2 shows a core part casting mold that can be used to make the light weight part;
The particulars shown herein are by way of example and for purposes of illustrative discussion of the embodiments of the present invention only and are presented in the cause of providing what is believed to be the most useful and readily understood description of the principles and conceptual aspects of the present invention. In this regard, no attempt is made to show structural details of the present invention in more detail than is necessary for the fundamental understanding of the present invention, the description taken with the drawings making apparent to those skilled in the art how the several forms of the present invention may be embodied in practice.
With reference to FIG. 1, a lightweight part 1 has a core part 10 and an outer wall body 12 that has a thickness D. This thickness D can vary or be constant as desired. A dense closed core surface layer 14 is arranged adjacent the outer wall body 12 and between the core part 10 and the body 12. The core part 10 has an inner area 13 and a core inner part 15 that is formed from metal foam. A clamping area 17 is also provided. The outer wall body 12 can also include contours 16, 16′, 16″, 16′″ that can serve to hold or guide the part relative to other, structures (not shown). Contours 16, 16′ and 16′″ have the form of projections or projecting portions. On the other hand, contour 16″ has the form of a recess or indentation.
FIG. 2 to FIG. 5 illustrate the stages that can be used to manufacture a core part.
