The Medicoat powder injection system offers a very flexible, fast and more comfortable connection of the individual injectors with the plasmatron. A new front securing ring for the nozzle now can port up to 6 injectors in pre-defined and secured positions. The place of each individual injector can be adjusted separately from the plasmatron, using a special injector-porter. Both together can now just be plugged at the desired places on the securing ring. A spring inside keeps the injector-porter at the right place. Unused positions get closed by small pins which protect against the spray dust.
