Improper Gun Settings for parts when spraying Powder


Forrest powder paintImproper Gun Settings for parts:

  1. Powder Concentration too High

Reduce Powder Volume settings

The Gun charges the air in a corona between the gun tip and the grounded part. That corona in turn charges the powder. If the powder volume is excessive there in not the opportunity for the powder to get properly charged

  1. Air Volume too High

Slow down the Powder Delivery Velocity

Powder can be blown past the part before the electrostatic charge can take effect

  1. Air Moisture Level too High

Control the Spray room environment

Excessive moisture draws the charge out of the corona so the effect is like having too much powder or lowered voltage at the gun tip

  1. Control the plant air supply moisture level
