Manual and automatic spraying

Spraying can be made with conventional guns, with membrane guns, with rotational flow HVLP guns, with streamline flow LVLP guns, with Airmix or Airless pumps! Depending on the type of equipment there will be a certain technological loss, which can vary from 120%, in the case of conventional guns, up to 7%, in the case of Airmix, Airless or LVLP guns! Also, the type of equipment to be used will indicate a certain productivity regime, depending on the type and size of the objects that need coating. In the case of industrial coating, then an Airless gun is indicated to be used, for example for metal works. Also, if dealing with an industrial coating, but the coating has to be done on visible subassemblies, then the solution might be a HVLP or Airmax gun, depending on the size of the painted surface. If the surface is already mounted and the emphasis falls on the chromatic juxtapositions, then the only solution is an LVLP gun.

With the exception of the LVLP gun that binds directly to a turbo compressor powered at 220V which does not require ventilation and exhaust, other sprayers must be bonded to a screwed turbo compressor, fitted with a tank, an air dryer and decanting filters. Also, the painting must be done in a painting booth or a space equipped with ventilation and exhaust systems, because of paint gases, formed as a result of high pressure paint application, which have to be eliminated.

Automated spraying can be done by machines equipped with automatic HVLP or LVLP spraying heads that can either be fixed and so the piece to be painted can be brought there, or mobile and so they can be displaced to the fixed piece to be painted. Such machines are intended for serial production of subassemblies to be coated with primers, paints or lacquers.
