ABSTRACT:
A fuel tank having an integrally molded heat shield. An insulating material is secured to one surface of a pad made from foamed high density polyethylene (PE). The heat shield is placed within a blow-molding apparatus. A hot pliable HDPE parison is extruded adjacent a second surface of the pad. The parison contacts the second surface and causes the second surface to heat and partially melt. The parison is urged against the pad. HDPE material from the pad and parison intermingle and fuse. Pressure from the blow molding process aids in intermingling the molten surfaces together to form a strong integral attachment.
