When coating stamps and punches, ensuring surface quality is essential. These surfaces require smooth, dustless coatings with good adhesion to accurately replicate finely detailed relief structures. Stamps and punches have narrow tolerances and may therefore only be coated within a certain temperature range.

We fulfill these requirements with Custom Coating Solutions

  • The surface to be coated faces downwards to keep it dust-free; the target is placed on the underside of the coating chamber
  • Our SPUTTER technology, supported by LGD® (Lateral Glow Discharge), guarantees smooth coatings with a very good adhesion
  • The temperature is kept in a narrow range
Example Custom Coating Solution S-MPuls for coin punches of Monnaie De Paris

For coin punches, we have developed a Custom Coating Solution for high-quality coatings with a good amorphous structure, high density, surface quality and high reproduction accuracy.

Technologies applied:

  • 1 x DC pulsed magnetron SPUTTER cathode with rotating magnetic field
  • SPUTTER source arranged at the bottom of the chamber
