In conventional powder spray systems, paint atomization
occurs via high-velocity air jets, forcing powder through small air holes in
the gun face caps. Air pressures used range from 40 to 80 psi. If the atomized paint particles travel at too
high or too low velocities, poor application can occur, preventing powder from adhering
to the surface.
Powder Atomizer
Rate: Too High
- Low film build
- Low transfer efficiency
- Fat edges
- Poor penetration into recesses
Powder Atomizer
Rate: Too Low
- Powder spurting, surging, or puffing
- Streaking on parts
- Low wrap around
Controlling the powder atomization rate is an important step
in application. If you need some
additional assistance with your spray equipment and controlling powder
atomization rates, feel free to contact us today and we
