In Air Corona

F&B In Air Corona works under atmospheric pressure. It increases surface tension of non-conductive materials enhancing the bonding of inks, glue and coating.

It is suitable for treating small areas of three-dimensional objects or small areas of plastic materials or heavy gauge sheeting.

The system is composed of a high-frequency and high-tension digital generator with integrated transformer and a nozzle that directs the discharge toward the substrate that needs to be treated by an air flow. Compressed air is not required.

Main applications

  • Ink jet and Pad printing lines for better printing quality
  • Coding and marking lines to improve code readability and to guarantee a long lasting bond
  • Label lines for better adhesion of labels on 3D objects.

Ink jet printing

Ink jet printing allows customisation of packing marks or of objects on a production line. In Air Corona is the solution to enhance the bonding of ink on plastic surfaces especially when UV ink are used. It is enough to put the nozzle before the printing nozzle.

Gluing of gaskets with a strong seal

In the automotive or white goods industry to enhance the bonding of glue on the gasket. In Air Corona activates the surface increasing the surface tension. The system is installed in the plastic or rubber extrusion line before the application of the glue.
