At Blösch, we master three different laser engraving processes:
Laser matting is a surface engraving technique with an almost imperceptible engraving depth that can be used on translucent materials such as sapphire or mineral glass.
This procedure is compatible with decorative PVD metallizations (before or after engraving), anti-reflective coatings and their combinations offering almost unlimited design possibilities.
In combination with our coatings laser matting offers genuine added value for your designs. Stunning aesthetic effects can be obtained by metallizing a previously laser-matted substrate: the matt metallization is born!
- Deep engraving and 3D engraving:
Deep engraving allows to remove material in depth to create a 3D effect. Among the materials processibl using this technique are sapphire, mineral glass, brass, gold and ceramics.
Selective surface ablation removes defined areas of a previously deposited coating.
That way, various ornaments and decorations can selectively be removed from a previously metallized sapphire crystal without damaging the substrate.
This procedure offers many advantages: No design limits, noncontact machining, no masking constraints.
The only limit is your own imagination!
