Corona Treater
Surface Treatment

Corona Treater

Corona treater uses a high-efficiency discharge treatment method to increase the surface energy of printing substrates and improve ink adhesion. Treatment intensity, electrode clearance, and material speed can all be adjusted to suit different substrates and production conditions. It also integrates web guiding and rewinding functions for convenient roll-to-roll processing.

Advantages
  • Adjustable corona treatment intensity to match different materials and surface treatment requirements.
  • Adjustable electrode gap for greater control over the treatment process.
  • Variable material speed to accommodate different production requirements.
  • Automatic shutdown protection stops the corona discharge when material movement stops, reducing the risk of substrate burn-through.
  • Optional slitting function combines surface treatment and slitting in a single process when required.
  • Integrated web guiding and rewinding keeps the material properly aligned and neatly wound after treatment.
