Equipment features

  • By using a plasma gun with the pressure inclination type discharge method, even in the comparatively low pressure range of 10-3Pa's, a large current plasma of over 100A, the most suitable low voltage for generation, is created.
  • With large current plasma, high assist energy and promotion of the ionization of materials occur, thus it makes also highly reactive, high-speed film deposition possible.
  • Due to ions in the plasma spreading without directivity, it is possible to have large area assist on three dimensional objects such as concave surfaces.
  • Automatic stability control of plasma assist forming condition
* We handle the installation and modification of plasma guns to existing equipment
