Abstract
A method for making a substantially tube-shaped conduit resonator having a plurality of plastic component parts, the conduit resonator having a tubular hollow body and at least one tubular molded part arranged inside the tubular hollow body and connected to the tubular hollow body, the method comprising the steps of: making a molded part via an injection molding process in an outer tool having an inner mandrel; injecting the hollow body between the molded part and a surrounding outer tool wherein the molded part along with the inner mandrel serve as an inner tool; and, thereafter, via a blow molding process, seating the hollow body on the inner wall of the outer tool and reshaping the hollow body on the outer wall of the molded part and bonding the hollow body, in part, to the outer wall of the molded part.
