Discharge rollers for corona treatment

We supply a wide range of discharge rollers for corona treatment, with technical features and dimensions varying according to the type of substrate and the target industry.

Discharge rollers come with three different coatings:

  • Silicone sleeve, for rollers combined with aluminium or stainless coated electrodes, mainly used in corona treatments for extrusion and printing applications
  • Vulcanized silicone for extrusion coating, converting and cast film applications
  • Conductive ceramics, used in combination with ceramic electrodes for printing and converting applications

Depending on the type of substrate to be processed, Ferrarini & Benelli chooses the coating that optimizes corona discharge uniformity, ensuring roller durability and minimizing machine downtime.

In addition to supplying new rollers complete with coating, Ferrarini & Benelli also offers the service of roller vulcanization or roller coating curing, which increases the durability of the component.

  • 75 mm
  • 98 mm
  • 100 mm
  • 120 mm
  • 150 mm
  • 200 mm
