In an effort to reduce volatile organic compounds as required by European regulations, Renault has replaced a solvent-based paint line with a water-based line at its factory in Flins. Besides the main objective others were to be taken into account in order to select a process: - increased production volume (65 vehicles per hour); - more than 90 % of vehicles must be good in the first run off the assembly line, - 12 months from order to delivery and a trial period and period of attaining the production rate of 3 months for 15 base colours. It remained also to be seen if that process would allow a noticeable increase of the global performance. A validation process was launched involving different spraying systems. The different evaluations and validations were conducted with Dupont, Renault's partner for paint products. In terms of the application process, the initial validations were carried out with three suppliers: ABB, SAMES and Dürr. Dürr was chosen for the project at Flins thanks to the technical and economic advantages of the process. The following were chosen: 4 robots with Ecobell 2 internal charge bowls for the door interiors; 5 + 1 robots with Ecobell 1 external charge bowls for the first base coat, 3 + 1 robots with Twingun external charge spray guns for the second base coat; - each robot is equipped with a lock, providing secure access to the atomizers and colour changers, for example. This should allow for minimum intervention without ceasing production.
