3 DÜRR PROCESSES FOR AIRCRAFT FOR AIRCRAFT PAINTING PAINTING Aircraft paint finishing is a delicate process where structural, pre assembly and sub assembly parts must be treated in different processes before the final coating is applied. The main processes for the surface treatment are:» Wet cleaning» PFD (penetrant fluid detection)» Anodizing» Sealant application» Primer and top coat application» Waxing DIPPING SYSTEMS AND CONVEYOR SYSTEMS PAINT BOOTHS AND OVENS ROBOTIC PAINT APPLICATION SUB-ASSEMBLY PARTS PRE-ASSEMBLY PARTS YOUR EXPERT FOR EVERY DIMENSION AIRCRAFT PAINTING: Between the process steps, there are also a few intermediate processes as sanding and grinding, activation, dry cleaning and curing required. STRUCTURAL PARTS» Preparation (Grinding, cleaning, activation)» Primer, Top coat» Drying/Curing Dürr offers customized solutions for your individual requirements.

PARTS PART SIZE (UP TO) [LxWxH] BOOTH/TANK SIZE (UP TO) [LxWxH] Dipping systems The first steps of the surface treatment are cleaning and degreasing of the parts, followed by pickling or etching and as a last step the deoxidizing usually these process steps are treated in tanks. After the wet cleaning process the main stressed structural parts are proofed with a non-destruction testing procedure (NDT) such as: Penetrant fluid detection (PFD) or liquid penetrant inspection (LPI). Before starting with the anodizing process, the parts have to be wet cleaned again to remove the PFD and to keep the surface clean. Conveyor systems An overhead conveyor system (OHC) is used to convey the parts to the dedicated tanks. A conveyor enclosure protects the environment from air contamination by hazardous fumes and a drip pan prevents the contamination of the surrounding areas. OHC with sheet metal cover and drip pan to prevent contamination on the site Anodizing line Small Large Structural parts Structural Parts Keel Beams 34 x 0,5 x 5 m 111 x 2 x 16 ft 4 x 0,5 x 4 m 13 x 2 x 13 ft 40 x 8 x 8 m 130 x 26 x 26 ft 35 x 1,5 x 6 m 115 x 5x20 ft 8 x 5 x 5 m 26 x 16 x 16 ft 55 x 20 x 10 m 180 x 65 x 33 ft Booth and robot paint application The s are for preparation, sanding and painting. Keeping the temperature and humidity inside the is important because with every change of temperature the paint viscosity changes and so does the finishing quality.therefore it s essential to control the temperature and humidity depending on the outside conditions. EcoSmart AC is the right solution for this task. Automated painting application with paint robots and paint supply system is becoming essential in the aircraft manufacturing processes. At Dürr, all the above processes are ready for IIoT. Air pollution control systems VOC-Concentrator In some cases, governmental laws, local requirements, and VOC s restrictions, require air treatment unit. Common practice is to use catalytic or thermal oxidation systems to treat the concentrated air stream. Ecopure KPR adsorption system is a state of the art air treatment for this kind of process.

The range of the curing temperature is from 40 C/ 104 F to 120 C/ 248 F. Dürr offers temperature control and uniform air distribution to avoid damage of the part and to assure the required process parameters.
