Atmospheric Plasma Treatment

Atmospheric plasma treatment is ideal for in-line processing or for the plasma treament of small areas of larger parts that would otherwise be too large for vacuum/batch processing. Atmospheric plasma is very effective at activating and cleaning the surface of a material, increasing the adhesion characteristics and making it easier to bond, paint and glue. The atmospheric plasma nozzle can be clamped to a fixed point or to a simple multi-axis robot making it ideal for industrial applications.

The relative motion between the atmospheric plasma and the workpiece during treatment ensures that there is little or no heating of the substrate. This makes the system suitable for treatment of a wide range of materials including polymers, glass, ceramics and metals. The atmospheric plasma is formed from compressed air and does not require expensive gases for operation. A range of exit nozzles are also available for increased treatment area or for finer, more localised treatments.  The video below demonstrates the application of a dual atmospheric plasma system in an automotive setting for the removal of flashing and activation of the surface prior to painting.

Atmospheric plasma torches are suitable for:

  • fast, localised atmospheric plasma pre-treatment of parts prior to bonding
  • ultra-fine atmospheric plasma cleaning
  • surface activation with atmospheric plasma
  • highest quality treatments
  • localised treatments
  • very low operation cost & easy integration with automated lines
