Blow-Molded Air Deflector

This blow-molded 1-piece air deflector, mounted near the wheels to deflect air, improve fuel efficiency, and reduce dirt and ice retention, replaced a 2-piece injection-molded deflector. An innovative blow-molding technique involving high pressure and high vacuum in the tool enabled uniform wall stock and fine-texture graining on both sides of the part to help it harmonize with nearby injection-molded parts. A special blow-moldable TPO grade was developed to maintain impact and ductility to -30C at lower density. Vs. the earlier injection-molded design, mass was reduced 5%, tooling costs were lowered, and a welding operation was eliminated.
