The Chinese electric vehicle manufacturer BYD Auto Company selected Dürr to equip it with painting technology for its first European passenger car plant.
Over the coming months, Dürr will send more than 120 robots fitted with EcoBell3 atomizers to Hungary for various painting lines to paint its New Energy Vehicles (NEV),
Dr. Lars Friedrich, Head of the Application Technology division at Dürr, says this is the first order the company has received from the Chinese carmaker in the passenger car segment. Dürr Systems AG was successfully audited extensively by BYD before being considered as a supplier.
Latest Robot Generation for Painting Process
The painting lines will use Dürr’s latest EcoRP series painting robot, available in 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, which are additional aids in the painting process.
Sustainable Paint Application
EcoBell3 high-speed rotary atomizers ensure flawless painting quality with uniform shade, flow, and layer thickness. 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” – which are what the fitting bodies matched exactly to the internal diameter of the hoses are called – push paint to the color changer and return any leftover paint into the paint container, leaving no trace of residue and eliminating the need for cleaning. This process reduces paint and the rinsing agent consumption, benefiting the budget and the environment.
Automated Body Cleaning
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, which is a deal for BYD’s various NEV types.
