Abstract
A hollow plastic product including a hollow main body, a reinforce member and a connector pipe is provided. Such a hollow plastic product is, for example, used advantageously as a component of an air-intake system or fuel supply system of an automobile. In one example, the hollow main body is a duct, hose or tube extending over a length, and the reinforce member is ring-shaped so that it extends around a circumference of an outer surface of the hollow main body. The reinforce member is manufactured by injection molding and is used as an insert when blow-molding the hollow main body, so that the reinforce member is integrally formed with the main body. The reinforce member has a defined welding surface formed with a first hole, to which one end surface of a connector pipe is thermally welded. Then the hollow main body is formed with a second hole in alignment with the first hole, thereby defining a fluidic communication between the hollow main body and the connector pipe.
