Abstract: In order to simplify the manufacture of an insert part, which has two web structures, each of which forms a plurality of webs, it is proposed that the insert part is manufactured by a molding process in such a way that the two web structures touch each other in respective contact surfaces, but nevertheless remain separated from each other by a mold parting plane. This has the technical advantage that the respective outer contour of the webs of the respective web structure can be defined exclusively with a respective mold part without an offset of the respective other mold part having a negative effect on the shaping of the webs.
