Important tips for Laser Etching Glass

Laser engraving machine can engrave on the surface of the glass, but the engraving depth is not very deep,and it can’t cut glass. In general,the laser can form a frosting or breaking effect on the surface of the glass.

In generally, laser engraving glass technology is used on laser engraving art glass. By sticking a layer of adhesive on the glass, By sticking a layer of adhesive on the glass, the laser engraving machine directly engraves the imprint on the sticker, so that it can be directly coated on the inprint. .

It can also be combined with the sand blasting machine. After carving, the blasting machine is used to continue the deep carving, then the carving depth can be deeper. Compared to traditional art glass making, laser engraving machine technology can save time and production costs.

Usually the user wants to get the effect of frosting instead of breaking. The key depends on the texture of the glass and whether the hardness is consistent. Glass engraving is usually difficult to control.

Follow the steps which can make a smoother matte result:

1. Apply a little detergent on the carved.

2. Cut a piece of newspaper or napkin,which should be slightly larger than the area to be engraved, completely soak the paper with water, squeeze out excess water, and place the wet paper in the engraved area to avoid wrinkling.

3. Place the glass in the laser engraving machine and engrave when the paper is still wet.

4. Remove the glass, remove the remaining paper, and clean the glass surface.

If necessary, lightly polish the glass surface with a 3M Scotch Brite. In general, the laser power setting should be smaller, the accuracy is set at 300dpi, and the engraving speed is faster. Try to use large-size lenses for engraving.

When laser-engraved lead-containing crystals should be doubled, the lead-containing crystals have different coefficients of expansion than ordinary crystals, which may cause crystal cracks or breakage during engraving. A smaller power setting can avoid this problem, but you should always be on the lookout for a break. After the engraving, the surface can be cleaned with a damp cloth and colored with acrylic paint.
