Resource-efficient paint shop for SKODA




EcoInCure offers best possible top-coat quality and maximum process reliability by heating the bodies from the inside in combination with the innovative transverse mode of operation. SKODA will use the benefits of the new Durr oven in the future in the Mlada Boleslav main plant in the Czech Republic. Durr is supplying all the system and application technology, including the building, for the new paint shop. Production is set to start in June 2019.
But let’s stay with the oven for the moment: EcoInCure features nozzles with long throw distances that blow hot air into the inside of the body through the opening for the windshield. The flow velocity around the outer skin of the body during this process is minimal. This results in an undisrupted paint appearance with maximum quality. At the same time, optimum transfer of heat inside the body enables extremely homogeneous heating of both thin sheet and mass parts. The result is up to 30 percent shorter heating times with minimized thermal component stresses, which is especially important for drying electric vehicles and multi-substrate bodies. The heating concept of EcoInCure reduces the electrical energy requirement by 25 percent and regulates the drying temperature with previously impossible precision and speed. The exhaust air from the ovens is purified via the integrated Ecopure® TAR afterburning system with heat recovery and then used for the oven heating system.
The entire plant including data acquisition, data evaluation, and plant monitoring is controlled by the Durr software solution iTAC.MES.Suite. The modular MES system provides detailed information on the production workflows and the consumption data at all times. For the first time, for example, Durr is using the electronic quality card for the drying process, which makes it possible to track the drying quality of each body.
Before the bodies are given their top coat in the painting booth, they undergo pretreatment (PT) and electrocoating (EC). The Rodip E rotational dip process is used for cleaning and applying for the corrosion protection. The rotation of the entire body optimizes the immersion, flooding, and draining process. This tried-and-tested technology from Durr is already used to coat well over 10 million bodies worldwide each year.
