Glass laser engraving: definition and technology
Glass laser engraving
How does it work?
Laser engraving on glass uses a focused laser beam to modify the surface of the glass, creating detailed patterns, text, or images. In practical terms, the laser heats the glass surface, causing controlled micro-fractures that form the desired pattern.
This non-invasive method is highly precise, even on curved or complex surfaces.
The CO2 source
Ideal for glass laser engraving
The CO2 laser is the technology of choice for glass marking. Its infrared beam acts on the surface without contact or mechanical pressure, ensuring fine, precise, and permanent marking.
Thanks to a controlled thermal effect, this process creates a subtle but durable contrast without the risk of cracking or chipping, even on curved or fragile surfaces.
This technology is perfect for engraving logos, text, or decorative patterns. It can be used on a wide range of glass objects: bottles, flasks, glasses, and jars. Laser engraving on glass is particularly suitable for professionals in the customisation industry (gifts, limited editions, promotional items, trophies, etc.).
Glass laser engraving: the main advantages
Laser engraving offers many advantages that make it the technique of choice for working with glass.
- Non-contact: the laser beam acts without mechanical pressure, which reduces the risk of cracking or breakage, even on thin, curved, or fragile glass (such as crystal).
- Unmatched precision: the laser engraving is sharp, with no smudges or residue, allowing for extremely fine details.
- Speed: get high production rates without sacrificing quality.
- Durability: the laser marking is permanent and resistant to fading, heat, and repeated cleaning.
- High-end finish: its high resolution is ideal for delicate patterns, fine lettering, or complex logos. This level of detail is particularly appealing to the luxury, spirits, and cosmetics industries.
- Adaptability: it is compatible with all glass shapes (bottles, jars, stemware, cones…) and can be adapted to different angles, in particular through the use of a rotating axis (a cylindrical attachment is required).
- Improved working environment: laser marking is dust-free, sustainable, and features a low noise level, a significant advantage for shops or events.
What are the main applications of glass laser engraving?
Glass laser engraving
Bottles and glasses
Ideal for enhancing wine bottles, spirits, cocktail glasses, or champagne flutes, laser engraving allows you to add logos, names, dates, or personalised messages with finesse.
It enhances products and strengthens brand identity, making it highly prised in the premium beverage industry. The marking is permanent, elegant, and done without contact or alteration of the material, even on curved or fragile surfaces.
Focus on the cylindrical attachment for glass laser engraving
The cylindrical attachment is a specially designed rotating tool used in laser machines to accurately engrave cylindrical objects, such as bottles, flasks, and drinking glasses.
