The CO2 snow jet system has been integrated into a paint booth measuring 5.5 x 4 x 3 meters together with a turning station, and needs much less space than a powerwasher with a dryer.

onform to the motto “less is more”, Volkswagen Plastics Technology in Braunschweig in Germany has started using a single-layer painting system for a new interior component. The process not only reduces the consumption of resources and pollutant emissions, but the semi-transparent metallic painting also lends the already-shiny injection molded part a sophisticated look. However, the painting system demands an absolutely clean, residue-free surface. This has been achieved with the aid of a dry CO2 snow jet cleaning technique which is gentle on materials.
In order to economize on resources and costs as well as reduce environmental damage, Volkswagen’s production plants implement the latest technologies such as cogeneration units, biogas plants, filler-free body paints and thermal afterburners to recover energy from solvent-polluted exhaust air. In the development and manufacture of interior components such as panels, trims, ventilation grilles and air diffusers, Volkswagen finds ways of further increasing sustainability at its Plastics Technology in Braunschweig.
