In a method and apparatus for producing a composite component comprising a hollow profile and at least one injection-molded element, a hollow profile () is formed by means of internal high pressure fluid forming and is encapsulated with an injection molding material to form the injection-molded element. The hollow profile is expanded by means of internal high pressure in a closed combination tool comprising an internal high pressure forming tool element and an injection molding tool element, before it is encapsulated. The hollow profile is pressed on the tool engraving only locally in the region of the location to be encapsulated, keeping the outlet of the injection molding channel opening into the tool engraving clear.

Composite component and a method and device for producing the composite component

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.
