International. The manufacturer of machinery and installations for the automotive sector, Dürr, recently presented a new technology that offers greater flexibility and energy efficiency in the fields of Pretreatment and Electrodeposition.
The system called RoDip does not require inlet or exit ramps because the body of the vehicle makes a complete rotation of 360° in the immersion tank, which, in turn, allows to significantly reduce the length of said tank. The decrease in volume provides lower consumption of materials and energy.
RoDip produces a uniform layer thickness, even at critical points such as heels. This, together with the optimized immersion, flooding and draining process, ensures optimal corrosion protection.
Similarly, the Ecopaint RoDip E technology was announced, based on the development of a new heavy load conveyor, which is also adapted for the coating of commercial vehicles. Such a conveyor drives vehicles and minivans through the pre-treatment and immersion painting stages.
They also revealed the EcoDC MACS, it is an error-proof electrodeposition solution, which supplies electricity and voltage to the immersion tanks selectively, which due to its innovative power electronics has a positive impact on energy consumption, as well as on the quality of the coating of the bodies.
Finally, they developed the EcoMulticyclone Micro and EcoMultiCyclone Nano which is used to clean the pre-treatment vats used in the car painting process, contributing significantly to the quality of the coating.
The EcoMultiCyclone Micro filters coarse particles in the flow from the first degreasing areas after sheet metal. With particles of 50 μm in diameter a separation efficiency of 100% is achieved, and with a size of 30 μm, 90%.
The EcoMultiCyclone Nano removes even smaller particles, achieving a separation performance of 90% for a size of 10 μm and 100% for particles of 20 μm.
