  • Patent number: 5298215
    Abstract: In a method for the injection molding of objects of at least two independent parts, which are connected nondetachably but mutually rotatably, the subsequently produced part being injected at least partially into a mold recess of the previously produced part or injected at least partially about the previously produced part, an approximately hollow, cylindrical element (1) is molded to the part produced first in the region connecting this part to a rotatable part (18) that is to be produced subsequently, which hollow, cylindrical element (1) is thereupon surrounded by a mold (10) for the subsequent part (18) and, for the production of this part (18), either the outer space of the hollow, cylindrical element (1), which is closed off by a core, or the inner space (9) of this hollow, cylindrical element (1), which is not closed off, is injected for the production of this part (18), the part produced first being deformed in the region of the hollow cylinder (1) into an undercut with rotational symmetry by the press
