Powder doesn't enter the shielded areas and cavities of the product

Compressed air

• air transport pressures set too high (air is returned and thus prevented from adhering to the surface of the products)

Application equipment

• improper application method
• worn electrostatic parts (CORONA):
• the cascade fails to charge
• the electrode is damaged
• electrode O-ring - no current is conducted to the electrode
• worn TRIBO parts:
• poorly grounded application equipment parts
• charging hose
• powder coating gun

Application equipment setup

• the voltage on the electrostatic device is set too high
• the powder coating gun is too close to the sprayed surface during application (blowing off the powder)

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
