Application introduction

Glass laser engraving

With Oree laser machines​, fine details can be accurately applied to the material as clear, white glass etchings. For glass etching with a laser on conical objects (e.g. beer glasses or bottles) we recommend that you use a rotary engraving device, which will automatically turn your work piece during the laser engraving process, so that it remains in the correct position. It is not possible to laser cut glass.

WHICH METAL PRODUCTS DO YOU WANT TO MARK?

INDUSTRIAL LASER MARKING

Examples of applications

Glass laser engraving


Engrave glass simply and precisely with a oree laser engraving machine.​ Laser etched glass produces a fascinating matte effect. Very fine contours and details can be etched into glass as photos, lettering or logos, e.g. on wine glasses, Champagne flutes, beer glasses, bottles, mirror or window glass. Personalized gifts for parties or corporate events are memorable and make laser-engraved glass unique.

Industrial laser marking: Examples of applications

What is the point of buying a laser for industrial metal marking?

  • Why should I buy a laser for glass engraving?

     With a Oree Laser machine​, there is no risk of glass breakage due to non-contact processing. With a glass engraving machine, no templates are required like they are with sandblasting; the etching is done directly on the glass surface. If the glass really must be engraved deeply with sandblasting, the laser engraving machine is useful for producing the perfect templates. Firmly apply the sandblasting film onto the work piece and cut out the motif with the laser device, the workpiece can then be sandblasted right away.

Function and advantages of laser technology

  • Function of the Fiber Laser Cutting Machine

    The fiber laser cutting machine can be used for both plane cutting and bevel cutting, and the edges are neat and smooth, which is suitable for high-precision cutting of metal sheets. It is an energy-saving and environmentally friendly new products with space saving and gas consumption and high photoelectric conversion rate.

    • Advantages of a Oree laser

    • Excellent beam quality and good cutting quality

    • Fast cutting speed and high production efficiency

    • No burr in the cutting, high cutting precision

    • Auto focus, easy to operate and maintain

    • Very low cost of use, cost-effective

    • Closed design, safe and pollution free

    • Fast cutting speed and high production efficiency


  • Function of the CO2 laser cutting machine

    The CO2 laser cutting machine adopts a focusing mirror to focus the CO2 laser beam on the surface of the material to melt the material, while blowing the melted material with a compressed gas coaxial with the laser beam, and moving the laser beam and the material relative to each other along a certain trajectory to form a slit of a certain shape

    • Advantages of a Oree laser

    • The output continuous laser is to make the cutting section smoothest.

    • The laser cutting head does not contact with the surface of the material and no damage to the workpiece.

    • Can cut non-metallic materials and has a wide cutting range.

    • No need for molds, saving production costs.


  • Function of the fiber laser marking machine

    Fiber laser marking machine, with the good beam quality. Its output center is 1064nm, the whole machine life is longer about 100,000 hours, compared with other types of laser markers. The electro-optical conversion efficiency is more than 28%, relative 2%-10% conversion efficiency of other types of laser marking machine. Besides that it has outstanding performance in energy saving and environmental protection.

    • Advantages of a Oree laser

    • Can process a variety of metal, non-metallic materials.

    • Belonging to non-contact processing, no damage to the product, no tool wear, good marking quality.

    • Thin laser beam is thin, small processing material consumption and the processing heat affected zone.

    • High processing efficiency, computer control, easy to automate


Can round or conical objects be engraved?

Yes. By using the so-called rotary attachment, round and conical designs can be engraved along the entire circumference. The JobControl® laser software already provides all the necessary parameters. You only need to enter the diameter of your workpiece and the height of the graphic, and you are good to go.

Can glass break during laser engraving?

Depending on the type of glass and the lead content, slight cracking may occur. Thus, the behavior may vary from piece to piece. Place a damp paper towel on the engraving area. This dissipates the heat better and prevents the glass from cracking. Cheap glass can often be engraved more easily than crystal glass; the reason is the higher lead content.


How to get a clear, white engraving?

The use of a wet paper towel not only prevents the glass from cracking but also leads to a clear, white engraving result. The important thing is that there are no air bubbles or wrinkles in the paper, as these irregularities might otherwise be visible in the glass engraving. Please also make sure that the Air Assist is disabled, otherwise the airflow can dry the wet paper prematurely. Alternatively, you can also use masking tape. To minimize the effect of the heat on large surfaces and thus optimize the engraving result, the graphics should be converted to gray scale (e.g. black graphic into 70–80 % black). In this case, no wet paper towel or masking tape is necessary.


How to get the best effect of photo engraving on glass?

Use gray scale rasterization of 70 % black; thereby somewhat less heat is applied to the glass, and the result is better. We recommend an average resolution of 500 dpi and the use of the “ordered dithering” rasterization method; this fits the image data optimally to the material.


Can mirrors be engraved as well?

You can make an extraordinary decorative element out of any standard mirror. When using the fiber laser, you can engrave the mirror from above through the glass. The glass does not react with the fiber laser, so only the mirror layer is ablated. The glass itself is not scored, because it only responds to the wavelength of the CO2 laser source. The subsequent cleaning is very easy to do, because the material removed by the engraving falls onto the table beneath the mirror, and little dust is left on the mirror itself. Acrylic lacquer is applied to the back of the mirror. The positive effect on the mirror: The laser-engraved part of the glass has no mirror layer and is transparent. Thus, the colors of the lacquer remain bright and intense through the transparent glass.
