Aerospace composites specialist Cotesa has selected Airborne to supply a robotic production system to automate its edge sealing operation for 3D composite parts.

According to Airborne, edge sealing is ordinarily a manual process that leads to quality problems resulting in rejected parts or repair work, and to worker fatigue because of the tedious, repeated motion.

As well as this, the 3D geometry of every part is different, there can be thickness variations in the edge, and the edges can be chamfered. This high variation in geometries leads to a large ef-fort in programming, if traditional methods are followed, and robot programming and testing is so large that it is prohibitive to use automated edge sealing in most cases.

Airborne says that its automated edge sealing system can help ensure a constant quality during production and reduce the amount of manual labour required. Airborne’s system can translate the 3D part design directly into the machine instructions and process settings, without the need of any robot programming. It incorporates a dispensing system can handle the variations in part shapes and ensures that the edge is sealed within the required tolerances.

“The edge sealing process has been a difficult process for many years, so we are happy that Air-borne can help us in making it more efficient and safer,” said Christian Bartsch, CEO of Cotesa.
