DÜRR PROCESSES FOR AIRCRAFT PAINTINGFOR AIRCRAFT 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

Between the process steps, there are also a few intermediate processes as sanding and grinding, activation, dry cleaning and curing required.

Dürr offers customized solutions for your individual requirements.

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.

Energy saving ovens

Painted parts have to be dried by convection, mostly in a separate dryer or curing oven.

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.

Booth and robot paint application

The booths are for preparation, sanding and painting. Keeping the temperature and humidity inside the booth 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 manufac-turing processes. At Dürr, all the above processes are ready for IIoT.

» Top loading curing and drying oven for CREP parts

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.

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.
