First the drill dust is removed, then the smear in the bore holes softened and afterwards completely removed by a permanganate solution.  The result is a micro fine textured resin surface.

  • Process modules in stainless steel execution for high process temperatures
  • Fully automatic dosing based on area calculations
  • Electrolytical regeneration of permanganate without additional chemicals
  • Fully automatic, individual proportioning controlled by analog level transducers
  • Ultrasonic transmitters support the swelling and cleaning process
  • Automatic vapour trap for the prevention of bath contamination due to vapour movement
