FUNCTION
When the automatic powder spray gun is turned on at the
controller, connected at (1), the cascade (2) is activated
and provides high voltage to the gun. When the gun is
activated, the powder supply, connected at (3), and the air
supply, connected at (4), are also activated. The powder
migrates through the passages of the gun and comes in
contact with the high voltage created by the cascade.
The high voltage differential between the grounded work
piece and the electrode of the coating gun generates an
electric field, which transmits a negative charge on the
individual powder particles.
Since these particles have the same charge as the spray
gun, they are repelled, distributed in a fine cloud and de-
posited evenly on the grounded work piece. Powder that
does not initially make contact with the work piece is caught
in the electrical field and wraps around to the backside of
the work piece. This powder coating technology provides
more effective material utilization, time savings, greatly
improved coating quality, minimal cleaning effort and a
healthy working environment
