The Openair® plasma system RD1010 is especially suited for sensitive and geometrically flat surfaces. The plasma treatment is carried out by two single nozzles, which are moved in a circle around a common axis of rotation. The plasma streams exiting from the rotation units run parallel to the axis of rotation.

Due to the rotation, plasma treatment is achieved with high relative speed across the component or the film. This results in very even treatment with low thermal impact and a large process window. Depending on the speed of rotation and the treatment diameter, the RD1010 plasma nozzle can achieve treatment travel speeds of up to 50 m/min.

Examples of typical RD1010 plasma rotation nozzle applications:
  • Blow-molded plastic packages prior to wet labeling
  • PCB cleaning: prior to printing with resistor paste (130 mm treatment width)
  • One-sided film treatment assured (> 72 mN/m).
  • Glass or mirror surfaces: full-surface cleaning prior to bonding
  • Plastic panels: pretreatment prior to coating and gluing
RD10xx Special design plasma nozzle:

Like the RD1010, the RD10xx has two single nozzles, which are moved in a circle around a rotation axis. In addition, with this special design, the distance between the two single nozzles can be adjusted manually.

This allows a flexible adjustment of the treatment width to the individual requirements. Due to the optional closer spacing of the nozzle outlets to each other and the rotational movement, higher plasma intensity can be achieved.
