Valeo Uses Dürr’s Rotary Atomizer for the First Time

EcoBell paints plastic parts with minimal material consumption

Published: Thursday, December 7, 2023 - 12:00

(Dürr: Southfield, MI) -- Plastic parts are often painted using conventional spray guns. But with prices for materials and cleaning rising, high-speed rotary atomizers are becoming more cost-effective. Valeo, a global technology company, is using Dürr's EcoBell technology for the first time at its production facility in Hungary, resulting in heightened efficiency, increased productivity, and reduced paint consumption.

The EcoBell atomizer series sets the standard for intricate industrial painting tasks with its high application quality, minimal paint consumption, and short flushing time.

Plastic parts are often coated by spray guns, which cost less to purchase. Valeo has opted for a change: For the first time, the global supplier will use high-speed rotary atomizers at its Hungarian site.

In the future, an EcoBell rotary atomizer mounted on a Kawasaki robot will paint plastic interiors for electric vehicles. With an EcoPump AD package, a fluid board, a two-component mixing and dosing system, and the EcoBell high-speed rotary atomizer without high tension, Dürr is supplying the full range of equipment from paint distribution to application for the new paint shop.

Successfully proven compatibility

Before implementing any rotary atomizer at Valeo, Dürr had to demonstrate the compatibility of the technology with the company’s processes and standards. Collaborating closely with partner integrator ERMA Concept, Dürr successfully furnished proof at the ERMA Lab test center.

EcoBell’s performance convinces with its high-quality surface finishing results and cost-effectiveness. The atomizer’s high transfer efficiency and mix block upstream on the robot arm greatly reduce paint loss and rinsing-agent consumption while minimizing required cleaning. In addition, the cycle time is shorter than with the previous application, increasing productivity. Higher cost savings and efficiency improvements result in the rapid cost recovery of the initial investment for a high-speed rotary atomizer, particularly considering projected increases in paint and rinsing-agent costs. Minimal paint loss and rinsing-agent consumption also ensure a more sustainable painting process.
