1. A method for molding a plastic element, said method comprising the following steps:
providing a molding device, said molding device comprising two mold parts that can move relative to one another between an injection position, in which the two molds part are pressed against one another and define an injection cavity between them, and a stripping position, in which the two mold parts are away from one another, at least one of the mold parts having a wall defining a receiving surface, said wall comprising at least one slit extending between portions of the receiving surface; positioning a support element in the slit, said support element defining a support surface which extends substantially in the extension of the receiving surface, and further defining, with a wall of the slit, a passage; installing an insert in the injection cavity, against the receiving surface and the support surface; injecting molding material into the injection cavity, the molding material filling the cavity and penetrating the slit and the passage, the insert being pressed against the receiving surface and against the support surface under the effect of the pressure of the molding material in the injection cavity; and solidifying the molding material, the molding material contained in the injection cavity forming a body of the plastic element and the molding material contained in the slit forming a rib of the plastic element, the body and the rib being formed together integrally as a single piece, the insert extending between the body and the rib. |
