The Chinese electric vehicle manufacturer BYD Auto Company Limited is building its first European passenger car plant in Szeged, Hungary. To equip it with painting technology, BYD selected Dürr. Over the coming months, the German mechanical and plant engineering company will send more than 120 robots fitted with EcoBell3 atomizers to Hungary for various painting lines.

The painting lines will use Dürr’s latest EcoRP series painting robot, available in both six- and seven-axis variants for interior and exterior painting. The seven-axis robot offers high precision and flexibility for interior painting, reaching even the most difficult to access areas.

Six-axis robots will handle exterior painting. The scope of supply also includes the corresponding door, lid, and flap openers as additional aids for the painting process.

EcoBell3 high-speed rotary atomizers ensure flawless painting quality with uniform shade, flow, and layer thickness. When combined with the associated cleaning equipment and color change technology, the atomizer family minimizes paint and solvent consumption and enables fast color changes within the cycle time.

In the future, BYD will also be able to sustainably implement customers’ special color requests using Dürr’s standardized, modular EcoSupply P paint supply system with pigging technology. The “pigs”—the fitting bodies matched exactly to the internal diameter of the hoses—push paint to the color changer and return any leftover paint back into the paint container, leaving absolutely no trace of residue and eliminating the need for cleaning.

The EcoSupply P system reduces material consumption and shortens color change times.

This process reduces both paint and the rinsing agent consumption, benefiting both budget and the environment.

The supply scope also includes cleaning robots that remove dust and dirt particles from the bodies before painting. Flexible-action feather rollers clean different body shapes efficiently and independently of each other in nearly any combination and order—ideal for BYD’s various NEV types.
