When coating stamps and punches, ensuring surface quality is essential. These surfaces require smooth, dustless coatings with good adhesion to accurately replicate highly detailed relief structures. Stamps and punches have narrow tolerances and can 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 very good adhesion
The temperature is kept in a narrow range
Sample 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 as well as high density, surface quality and reproduction accuracy.
