Aeronautical paint removal using starch blast media.
This process, using a wheat starch, is used for automatically or manually removing paint from composite or metal substrates.
Paint removal can be complete (substrate stripping with no surface condition change) or selective (primary coating retained).
For uniform paint removal, Rösler developed a special nozzle. Compared with conventional cylindrical nozzles, this special nozzle provides optimised distribution of the media over a larger area (the hot spot is eliminated).
In the automatic mode, the paint removal operation is performed using a 6-axis robot (or a 7-axis robot when installed on a longitudinal carriage).
The paths are generated by a laser beam providing 3D mapping of the part to be treated.
