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

摘要

In a method and apparatus for producing a composite component comprising a hollow profile and at least one injection-molded element, a hollow profile (3) 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.

1. A composite component comprising a hollow profile formed by internal high pressure and at least one injection-molded element injected thereon; wherein:
the hollow profile is bulged by forming in an encapsulated region and is formed with a plurality of bulges; the injection-molded element extends over the encapsulated region and is formed in the shape of an annular lamella that includes a separate lamellae formed on top of each of the plurality of bulges and connected to each other by a web; and the plurality of bulges and the plurality of lamellae on top of the bulges are laterally aligned and parallel to each other.
