A molded article, e.g., a cross car beam (3), which includes a rigid support (a) having a plurality of perforations, e.g., rigid support (12), and a rigid hollow thermoplastic member (b), e.g., an air duct (15), attached thereto is described. A portion of the thermoplastic material of rigid hollow member (b) extends through at least some of the perforations of rigid support (a), embedding the edges of the perforations therein. The thermoplastic material extending through the perforations forms an attachment element, e.g., an attachment head (24), that serves to fixedly attach rigid hollow member (b) to rigid support (a). Also described is a method of preparing the molded article of the present invention, in which the rigid hollow member (b) is fixedly attached to the rigid support (a) during the blow mold fabrication of rigid hollow member (b).
