Often when looking for industrial paint spray guns you do not properly focus on the aspect of the transfer with consequent waste of sprayed product.<\/p>\n
It is simply the ratio expressed as a percentage between the product actually deposited on the surface and the total product sprayed. The higher this percentage, the less paint is wasted in \u201coverspray\u201d.<\/p>\n
First we must carefully evaluate the surface that we are going to treat, wood, leather and fabric are very porous materials while for example ceramic, stainless steel, iron are absolutely not.
\nDuring this phase, the pressurised paint with which we use our professional paint guns will impact on the product creating a rebound that will turn into a mist and dry powders.<\/p>\n
These represent waste that must be purified and disposed of, creating an unnecessary economic burden.
\nFor example, think of having to spray a layer of Teflon on a stainless steel pan, it will be much more difficult than applying a light resin on a hide for furniture, therefore you will need to find the right gun that is able to transfer the product without generating excessive mist to be purified.<\/p>\n
In the case of several spray guns working simultaneously on large lines or industrial plants, we must check that the same quantity of paint to be sprayed arrives on each single piece, and if necessary install flow regulators for spray guns.<\/p>\n

No, lowering the operating pressure too much will affect the spraying capability and finish of the paint, especially on very compact surfaces such as ceramic.
\nHowever, today’s technology allows us to choose \u201chow\u201d to transfer according to the processing we have to perform.
\nIn fact, there are HVLP, LVLP, traditional pressure or volumetric pressure spray guns, each of them able to transfer the sprayed product to optimize the transfer efficiency as much as possible.
\nIn the industrial process, even just a few percentage points can translate into huge economic savings.<\/p>\n

The ideal solution would be to test in your own field accompanied by a specialized spray gun technician, if this is not possible, here are some useful tips to make your choice.
\nHVLP spray guns, short for High Volume Low Pressure, take advantage of the large amount of incoming compressed air to obtain a high-performance finish at low operating pressures, 1.5\/2.5 bar.
\nThese are suitable for all types of products to be sprayed including glues and resins (simply choose the appropriate size of needle and nozzle).
\nVolumetric spray guns exploit the same principle as above and bring these results to extreme values such as operating pressures of just 0.4\/0.9 bar.
\nThey require an adequately dimensioned air system and are ideal for large production lines.
\nFinishing quality slightly lower than HVLP.
\nLVLP spray guns, short for Low Volume Low pressure, require just a few litres of incoming air and are able to obtain an excellent finish, the product is delivered in a completely uniform and delicate manner.
\nParticularly suitable for spraying low density products at operating pressures between 1.5 and 2 bar.
\n\u201cSoftpressure\u201d paint guns, patented by us, is a segment of guns that is intermediately placed between a traditional and an LVLP paint gun, in fact it allows traditional finishes at lower operating pressures (2 \/ 2.5 bar).
\nTraditional spray guns allow an adequate finish with standard operating pressures between 3 and 4 bar and enjoy a lower transfer efficiency than other product categories.<\/p>\n","protected":false},"excerpt":{"rendered":"
