Quality treatment of substrates at high line speeds

Converting applications such as Rotogravure /Flexographic printing solvent less/solvent based lamination, slitting, coating, Extrusion lamination /coating calls for treatment of verity of substrates at very high line speeds. IEEC’s RFIM Corona Treating Station comes with high definition ceramic electrodes which can treat metalized and non-metalized substrates at high line speeds.

Technical advantages include:

  • Web width up to 2100mm
  • Line speeds up to 600mpm
  • High definition ceramic electrodes with ridge profile to ensure uniform treatment levels at high efficiency
  • Corona Treater Roller made out of Aluminium
  • Dynamically and statically balanced Treater Roller
  • Precise air gap adjustment during operation
  • Specially-designed electrode ducts with air flow dynamics to ensure negative pressure during Ozone extraction for electrode cooling
  • Vacuum switch for ensuring negative pressure
  • S.S. Braided double dielectric sheathed high tension cable
  • Proximity switch for zero speed sensing and closed loop feedback for auto- watt density control
  • Assembly open limit switch for human safety
  • Glazed ceramic insulators for rigid mounting of ceramic electrodes
  • Pneumatic actuation of electrode heads for easy treading of film

Optional features


Neoprene Coated Nip Roller and Motorized Driven Treater Roller


Ceramic Coated Treater Roller for longer roller life


Air gap adjusters with digital readouts
