The point of metal powder spraying is not to open up the powder mist, but to keep the metal effect, film thickness and color consistent. The site should first confirm the powder type, sample standard and customer appearance requirements, and then control the powder fluidization, spray gun powder volume, conveying air/atomized gas, electrostatic parameters, gun spacing, angle, gun speed, pendant direction, curing conditions and recycled powder ratio. Metal powders are more prone to problems such as color difference, flowering, cloud spots, corners shining, uneven metallicity, and color drift of recycled powder than ordinary solid powder. Fixed spraying parameters should not be applied directly before the powder grade, gun model, workpiece structure, target film thickness and prototype are confirmed.
