On November 25th, the Bosch Rexroth plant in Mellansel, Sweden, received the “besser lackieren. Green Award 2014”. The contest, which was promoted by the paint industry magazine “besser lackieren” and the Fraunhofer Institute for Production Engineering and Automation (IPA), searches for the most efficient concepts in industrial painting technology. The jury awarded Bosch Rexroth the prize in the category “In-house coating – paint departments/paint shops with less than 50 employees”.

The currently most flexible and environmentally sound paint shop in European mechanical engineering was put into operation at the Mellansel plant in 2013. The new facility reduces energy consumption by around 75 percent. At the same time, it sets new standards for variety in coating thanks to the use of RFID technology.

“This award confirms that Bosch Rexroth implements pioneering resource conserving and energy efficient concepts in its own plants”, emphasizes Dr. Karl Tragl, Chairman of the Executive Board of Bosch Rexroth AG. “We stand by our commitment to climate protection and strive to reduce CO₂ emissions from our production facilities around the world.” The new paint shop at the Mellansel plant coats up heavy load hydraulic motors weighing up to 10 tons. The temperatures and water/color pigment ratios are monitored closely and any excess heat is recovered. As a result, energy consumption has gone down by 75 percent.

The motors are cleaned in accordance with the counter-current principle in which the dirtiest water is always used for the first cleaning stage. This extends the life of the cleaning tank water and significantly reduces the amount of wastewater.

By switching to water-based paints, the use of solvents is reduced by around 80 percent. The paint robots apply exactly the specified paint quantities without any excess, thereby further reducing consumption. As each robot is surrounded by an individual chamber, the spray mist remains in a tightly confined space and can be collected easily.

The paint shop also sets new standards in flexibility for a greater variety in coating. RFID chips written by the order fulfillment system are placed on each component and provide precise instructions on their specific paint requirements to the individual stations. This is a key element for the implementation of Connected Industry across the value stream. The plant is so flexible that it can implement a color change for each single component.
