Resin Fuel Filler Lid for On-Line Painting 2008-01-1286

A resin fuel lid capable of being electrostatically painted on-line with the vehicle body-in-white was developed to achieve a light weight fuel adapter assembly with improved color match to surrounding body panels when compared with outsourced painting. The fuel lid was molded out of a conductive, high heat capable PA/PPO resin, and painted with automotive body paint systems. Key development items for this part included validation of part conductivity, on-line capability of the resin material, development of an attachment scheme to achieve proper grounding of the part, determination of paint jig location for proper paint coverage and color match to the body, and evaluation of the final fit & finish. These studies were conducted in combination of both lab and on-line trials. Additionally, the final painted part assembly was extensively tested to achieve the appropriate quality of the surface treatment and strength and durability of the design construction.
