Railcar manufacturer saves paint and increases productivity with Graco

Bombardier Transportation is a leading global player in manufacturing railcars, with 59 production sites and engineers in 23 countries.

The French site of Bombardier has multiple paint booths with crews working five days a week, 24 hours a day. They use waterborne epoxy primer paint and solvent-based epoxy monolayer paint with a temperature of application between 20° and 30°C and a pot-life of four hours. Many technical constraints had to be solved within this situation, and more specifically: the feeder had to be close to the painters, supported by a moving platform of 30 meters long.
 

On-board circulation system

The solution was to create a distribution area for mixing paints with a ProMix 2KS or 3KS proportioner, depending on the paints used in each paint booth, with an on-board circulation system that can move up to 30 meters for railcar paint application. The ProMix proportioners came with the XTR7 airless gun and G40 Air-Assisted gun. Moreover, Graco Merkur and Husky pumps were installed for the paint circulation. 

INCREASED PRODUCTIVITY

In this way, Bombardier Transportation has been able to achieve paint savings and significantly increase its production thanks to the Graco proportioner equipment ProMix 2KS and 3KS. Other benefits for the company are reduced paint preparation time, reduced solvent emissions and increased dosing accuracy.
