A change of colour to reduce emissions

Challenge

When Renault decided to modernize its production facility in Dieppe in Northern France, the company needed to meet new, stricter environmental requirements and wanted to introduce water-soluble paints. At the same time, the top coat painting lanes which still operated in manual mode should be automated.

Solution

The complete project, from the EMU dust extractor and paint supply to the robotic painting was realised by SAMES (Exel Group). Renault opted for the „ACCUBELL® two-component solution” controlled by MOTOMAN PX-2900 painting robots for the base coat applicaion. This was based on the ability of the ACCUBELL® atomiser to change from solvent-based to water-based paints without interruption of production. The base coat line processes approximately 20 colours which are applied by four MOTOMAN robots. Two PX painting robots with high-speed spinning atomisers apply a first coat. After this first coat, an additional two PX2900 robots apply paint to the required thickness with ACCUGUN® spray guns. Between painting of two car bodies, the atomiser is moved to a filling station where it is flushed and filled with exactly the right amount of paint needed. The paint is not electrostatically charged until after decoupling from the filling station.

Results

The new painting lane, which produces 15 vehicles per hour, now tend to comply with the European directives regarding emissions of volatile organic compounds. In 2007, the emission level compared with the beginning of 2006 will be reduced again by 32% due to the conversion by paint suppliers from solvent-based to water-soluble paints.
