Abstract:
A method for producing a filled hollow structure includes producing an open hollow structure of a first material, positioning the open hollow structure on a tool adapted to hold the open hollow structure, filling the open hollow structure with a filler medium, and closing the filled open hollow structure with a second material. A hollow structure may be produced by such method, and a tool may be structured to perform such method.
