Vac Aero’s Kalisz, Poland-based operation has installed a system based on a Carbide Jet System (CJS) produced by Dortmund, Germany-based Thermico.

The system’s combustion chamber is fed by hydrogen, kerosene and oxygen fuel and optimised for spraying MCrAlY coatings on turbine engine components and tungsten carbide coatings on landing gear components.

Combustion and fuel configuration settings control particle temperature and velocity to achieve coating efficiency in less time and lower fuel consumption than other HVOF systems.

The system was installed in a 13’X13’X 10’ high (4X4X3m) soundproof booth.

The CJS torch is set in motion by a new Fanuc M20 robot with 8-axis movement (6 axes on the robot and 2 axes on a tilting turn-table integrated into and controlled by the robot).

The torch’s range of spraying temperatures prevents part overheating and an ID torch allows for spraying of parts with inner diameters as small as 6 inches (150mm).
