A paint shop that can fit through a door
Bietigheim-Bissingen/Karlstein, March 2017 – While the paint shop at a hearing aid manufacturer can comfortably fit through a standard door, another company manually paints extendable masts in a 70-meter long paint booth supplied by Dürr. For both projects, the Industrial Products area of Dürr's Application Technology division built the plant equipment at its Karlstein (Germany) site. After all, painting is required in many different sectors of industry, and it has to meet very different customer requirements.
In these automated paint shops, the workpieces to be painted are transported through the unit on so-called chain-on-edge conveyors. To ensure that they fit on the chain, their diameter must not exceed 30 cm. The parts are pretreated by ionizing, brushing, flame treatment, or CO2 cleaning, depending on the material involved. They then pass the automated spray guns while being rotated. There are usually four to six spray guns that are either fixed to a bracket or attached to a reciprocator or robot with which they can be moved.
The overspray is extracted horizontally from the spray booth and removed using cardboard filter boxes – in a similar way to Dürr's EcoDry X system, which is widely used in car production. After this, the almost finished parts pass through the evaporation zone, followed by the drying and cooling zones.
More automation please
"We have noticed that the industrial sector is also becoming increasingly demanding," explains Sabine Mewis, Industrial Products Key Account Manager at Dürr. "Customers are particularly interested in improved surface quality, a higher level of automation, a reduction in overspray, and lower emissions. Here, we clearly have the edge over our competitors – also when working together with other Dürr departments."
Industrial Products always supplies its systems – no matter whether they are painting machines or large-scale paint shops – as a complete system, including application technology and paint delivery equipment. "Our customers definitely appreciate our 'one-stop shop' principle," Sabine Mewis points out.
Dürr founded the Industrial Products area in 2014 with the aim of supplying not only the automotive industry but also other industrial sectors with products for the application of paint and viscous materials. The target group of this area within the Application Technology division includes industrial sectors such as plastics, wagon building, ceramics, wood, and furniture.
