Coating technology centre

 

The IPA coating facility forms a link between industrial demands and modern scientific analysis methods. The painting line fulfils the cleanliness, climatic and airflow requirements of the automotive industry. Three painting zones equipped with robot technology are fitted with separate ventilation plants and paint application systems. The adaptable equipment they contain enables a broad spectrum of applications to be reproduced, ranging from painting small components right through to vehicles and even ships.

All types of liquid coating materials can be processed (paints containing solvents, 2-component paints, water-based paints, powder slurries, UV-curing systems, “nano-materials” and even suspensions, such as enamel slurries).

The painting line corresponds with those used in automobile industry (e.g. downdraft speed 0.1–0.5 m/s, controllable temperature and humidity).

The robots can be programmed off-line and their programs converted (by external service companies) as well as teach-in methods used. The robots are fully-equipped with process technology and can be fitted with diverse flexible lifting devices and other manipulators.

Additional mobile, modular application technologies (dispensing technology - also 2-component, process air, rotational speed control, etc.) enable the line to be adapted rapidly to the task at hand. The spectrum ranges from simple process control valves, through PLC-controlled application technology, right up to bus-capable systems.
