SuperCorona, the Best Solution for Smooth Surfaces

  • In a Corona gun the high voltage electrode generates a big
    quantity of ions. Only a few ions charge the powder particles,
    the others remain free and are attracted by the part surface.
     
  • The accumulation of ions on the part surface can produce
    “orange peel effect” and “back-ionization” problems.
     
  • SuperCorona discharges the excessive free ions and
    significantly improves the surface quality.
     
  • The free ions generate a strong electric field that makes it
    more difficult for powder to penetrate into corners and
    recesses (Faraday Cage Effect)
     
  • SuperCorona discharges the excessive free ions and
    facilitates the powder penetration.
