Abstract
A method is disclosed for making a duct assembly including an internal component part such as a silencer is disclosed. The duct assembly may be made in a blow-molding operation in which first and second duct parts are formed from a single parison as a combined part that is then split apart to receive a component part in a housing and subsequently closed by a closure part. Alternatively, the first and second housing parts may be separately formed and a component part may be inserted into a housing defined by one or both of the first and second duct parts. The first and second duct parts may be joined and sealed by injection molding a ring over telescopically assembled ends of the first and second parts.
