Coating thickness variation

Pressurized air

• air transport pressures set too high (blowing off the powder)

Application equipment

• improper application method
• voltage fluctuations
• worn electrostatic parts (CORONA):
• the cascade fails to charge uniformly
• the electrode is damaged
• electrode O-ring - no current is conducted to the electrode
• worn TRIBO parts:
• poorly grounded painting device
• the charging hose is damaged
• the powder coating gun does not charge

Application equipment setup

• the powder coating gun is too close to the sprayed surface during application (blowing off the powder)
• the powder coating gun is too far away from the sprayed surface during application
• the relationship between conveyor speed and movement for automatic spraying is not optimal

Paint (powder coating)

• improper powder for the given application: TRIBO / electrostatics (CORONA)
• the powder is wet, fails to hold the charge
• the powder is too fine:
• the recycled material content is too high
• too fine from production

Part and its hanging

• insufficiently grounded product
• improperly suspended products
