Better coating parameters.
The film on the body is fixed by your spec. Every drop that misses the body is overspray you pay for twice: once as paint, once as sludge. A better parameter window puts more of each drop where it belongs.

What SprayVision tunes.Six parameters, set together
When more of each drop lands on the body, you need less paint for the same film. In this example the flow comes down from 100 to 85 % and the film build stays in spec.

Narrower patternLess driftBell speed decides droplet size. Finer is not always better: very fine droplets float away into the booth. SprayVision finds the speed that keeps the appearance and the droplets on target.

More wrapHigher TERobot speed and paint flow together set the film build. SprayVision balances them, so the lower flow still reaches the specified thickness.
Film-thickness spec heldSB50 is the pattern width at half of its peak thickness. Matching the overlap between passes to SB50 gives an even film without coating the same area twice.

Paint flow
When more of each drop lands on the body, you need less paint for the same film. In this example the flow comes down from 100 to 85 % and the film build stays in spec.
Parameter 2 of 6
Shaping air
Shaping air sets how wide the pattern opens. The right setting gives a narrower, denser pattern that lands on the body instead of drifting past it.
Parameter 3 of 6
Bell speed
Bell speed decides droplet size. Finer is not always better: very fine droplets float away into the booth. SprayVision finds the speed that keeps the appearance and the droplets on target.
Parameter 4 of 6
Voltage
The electrostatic charge pulls droplets onto the body. Tuned together with flow and air, more of them arrive instead of ending up as overspray.
Parameter 5 of 6
Robot speed
Robot speed and paint flow together set the film build. SprayVision balances them, so the lower flow still reaches the specified thickness.
Parameter 6 of 6
Overlap = SB50
SB50 is the pattern width at half of its peak thickness. Matching the overlap between passes to SB50 gives an even film without coating the same area twice.
