Airless Spray Guns TOP Paint is forced through a very small orifice using high hydraulic pressure. As with air guns, heat may be used to lower paint viscosity. It also produces a soft spray. Air-assisted Airless Guns TOP Compressed air is introduced through orifices in the airless spray tip holder where the hydraulically formed paint film is atomized. This allows hydraulic pressure to be reduced which helps lessen nozzle wear and the formation of tails in the spray pattern.
Bombardment charging happens to atomized paint from a spray gun as it enters an ionizing zone.
The particles are charged by air molecules in the intense electrical field created by a thin grid wire network. The charged atomized paint particles are then attracted to the parts which are grounded by a conveyor. The main advantage of this approach is the relatively high transfer efficiency and ease of color change. A comparative disadvantage is that this system requires a much higher voltage source than direct charging. Contamination of the charging system can occur if the parts to be paointed are not properly grounded.
