The Sure Coat individual controller or modular gun control system
supplies low-voltage dc power to the voltage multiplier in the spray gun
housing (2). The multiplier converts the low-voltage dc power to the high
electrostatic voltage needed for powder coating. The voltage generates
a high-strength electrostatic field between an electrode in the nozzle (3)
and the grounded part in front of the spray gun. The electrostatic field
produces a corona discharge around the electrode.
Flow rate air pressure pumps the powder from the feed hopper, through
the feed hose, into the inlet connector (1), and out through the spray
gun’s nozzle. As the powder particles are sprayed past the electrode in
the nozzle, they pick up an electrostatic charge and are attracted to the
grounded parts.
The spray pattern is controlled by the shape of the nozzle, the flow rate
air pressure, and the electrostatic field generated between the electrode
and the grounded part.
