Dürr’s innovative paint shop technologies, like the EcoDryScrubber for dry separation of overspray and the rotating dip-coating system RoDip, will make the plant at Yizheng one of the most environmentally friendly plants in China.
Bietigheim-Bissingen Germany, September 5^th, 2011 – As general contractor, Dürr is building a modern paint shop in Yizheng for SVW Shanghai, the joint venture between the Volkswagen Group and the Chinese SAIC Group (Shanghai Automotive Industry Corporation).  Thanks to innovative technologies, Yizheng will host one of the most environmentally friendly plants in China.

As with the current project being realized by Dürr in Nanjing, SVW also relies on the EcoDryScrubber in Yizheng. By using air recirculation, the innovative dry separation method reduces energy consumption by up to 60% in comparison to conventional spray booths. Furthermore, since fresh water and coagulant chemicals are not needed, the sustainability of the painting process is significantly increased. With the two lines in Yizheng, Dürr’s trendsetting EcoDryScrubber technology will already be in use in 40 applications on four different continents.
 
The rotating dip-coating system RoDip, with which over 25 million vehicle bodies have already been painted worldwide, comes into play in the pre-treatment and cataphoretic dip-coating. Through this, the rotation of the entire car body in the tank optimizes the immersion, flooding and draining process.
 
Before applying the base coat and clear coat, the exterior of the bodies are cleaned with sword brushes by two EcoRS 60 type robots. Thereafter, the line is separated due to capacity reasons and runs from the pretreatment in two tracks. 24 EcoRP L133 type painting robots in each of the two lines automatically take care of the interior and exterior painting. Even the opening of hoods and doors for interior painting, as well as the measuring of film thickness in the topcoat, is fully automated with robots from Dürr. The EcoLCC linear color changer used in the basecoat minimizes paint loss considerably when changing colors.
 
The UBS lines are each equipped with four Dürr robot stations which include a total of 28 EcoRS robots and the application technology for automatic seam sealing, underbody protection and rocker panel coating. One such robot also completes the installation of roof reinforcement dampings in a gluing station. In addition, an automatic cavity flood system for the preservation of body cavities is included in the scope of delivery. In order to meet capacity, this equipment is constructed in two tracks.
 
The new paint shop – designed for a primerless process and the use of water-based paint – has a capacity of 62 units per hour. This paint shop, issued by SVW in the first quarter of 2010 and dedicated to sustainability will go into operation in the summer of 2012. Then vehicles from both Volkswagen and Skoda will be painted there.
