Abstract
Methods for casting thin-walled structural elements made of alloy for automobile bodies using the diecasting, thixocasting, or thixoforming methods, as well as corresponding structural elements are described. In order to produce by these methods in particular body side wall parts including the A, B and C pillars, the castings are cast in several casting slices. The casting slices of a casting are cast, staggered timewise in succession using the same method and from the same alloy but in different casting molds or different parts of a casting mold. At the seams, the casting slices are cast together along a defined shapewise contour. The casting slices can be case together indirectly with interposition of a separate seam strip. However, they can also be cast onto one another, with an already cast first casting slice being placed in a second casting mold and cast together therein with the second casting slice. Complete body side wall parts are cast in three casting slices, with the seams being located in the roof and sill areas.
