  • Method of producing a composite component
    Patent number: 9387609
    Abstract: 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.
