    摘要: A method of producing a composite component, in which a hollow section is expanded, at least in regions, by internal high pressure. In a first step a region of the hollow section is expanded until it comes to lie against an edge region of a cavity of a combined hydroforming and injection mold. In a second step the cavity is filled with an injection molding compound. In a third step the hollow section, at least in regions, is expanded further, which increases the internal high pressure.

    摘要: In a method and apparatus for producing a composite component, a tubular hollow section blank is placed into a die cavity of a combination tool comprising an inner high-pressure shaping tool and an injection-molding tool. The combination tool is filled with a fluid in such a way that the blank is wetted from the inside by the fluid, and the ends of the combination tool are sealed by two axial molding plugs. The filled blank is then expanded under pressure . The finished hollow section is plastic-coated in the same tool. The hollow section is emptied after shaping in the sealed state, at least until it is no longer dripping, the pressurized fluid being expelled under pressure from the hollow section through at least one discharge channel formed in the axial molding plugs.

    摘要: The invention relates to a method and device (1) for producing a composite component, wherein a tubular, hollow section blank (5) is placed into the die cavity (3) of a combination tool comprising an inner high-pressure shaping tool (2) and an injection-molding tool, the combination tool is filled with a fluid in such a way that the blank (5) is wetted from the inside by the fluid, and the ends of the combination tool are sealed by two axial molding plugs (6 and 7). The filled blank (5) under pressure is then widened. The finished hollow section (22) is then plastic-coated in the same tool. In order to produce the composite component in a relatively simple manner and by a reliable process, it is suggested to empty the hollow section (22) after shaping in the sealed state at least until it is no longer dripping, wherein the pressurized fluid (19) is expelled under pressure from the hollow section (22) through at least one discharge channel formed in the axial molding plugs (6 and 7).
