The principle is very simple, as it involves immersing a piece in a bath of water-soluble or solvent-based liquid paint.
This painting method is still used in industries that prioritize corrosion protection over appearance. It is particularly useful for parts with hollow bodies or those requiring temporary protection.
Depending on the type of parts to be treated, the usable handling systems can range from a simple gantry to an overhead Birail or Monorail conveyor. Increasing demands for appearance quality and environmental standards make these lines increasingly rare.
