Atmospheric Plasma Treatment Explained

Atmospheric plasma treatment is ideal for in-line processing or for the plasma treatment 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 the 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.

Henniker Plasma: Atmospheric plasma treatment in the Automotive Industry

The Henniker Cirrus Atmospheric Plasma System displays localized plasma cleaning to give improved adhesion in the automotive industry. The surface is cleaned prior to the glueing step, in order to ensure a failure-free bond.

Henniker Plasma - Atmospheric Plasma Robot

Atmospheric plasma treatment is ideal for in-line processing & very effective at activating and cleaning the surface of a material, increasing the adhesion characteristics and making it easier to bond, paint and glue. Henniker's atmospheric plasma surface treatment systems can be integrated with a 3-axis robot to follow precise treatment patterns as part of an automated process..

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
