Abstract
The invention relates to a method for producing a tubular component as an article from a thermoplastic synthetic material while using an injection-molding device having a tool that forms an article cavity, having means for filling the article cavity with a thermoplastic molding compound, and having an injection device for injecting a fluid into the article cavity, wherein the injection device comprises a nozzle body, wherein the method provides that the nozzle body is used as a mold core for molding the shape of an end of the article, that the nozzle body is used as a carrier for an additional component to be incorporated into the article, wherein: a) the nozzle body first equipped with the additional component, b) the nozzle body is introduced into the closed article cavity, or the tool is closed around the nozzle body, c) the article cavity in a further method step is at least partially filled with the thermoplastic molding compound, d) a pressurized fluid is then induced into the article cavity by means of the injection device, wherein part of the molding compound is displaced into a secondary cavity, and e) the article is de-molded. The invention furthermore relates to an injection-molding device for carrying out the method.
