Laser engraving on glass has its main application in the packaging (bottling) lines of beer, wine and spirits.
Glass engraving is one of the most used for marking products intended for large-scale distribution (glasses, bottles ...) but is also widely requested in some industrial sectors of the building sector (e.g. for the production of window glass ).
Here's how it works:
The type of laser used for glass media is a CO2 laser. CO2 laser engravers exploit the potential of a gas source obtained by mixing CO2, nitrogen, hydrogen and helium.
The mixture, excited by the passage of current, is able to emit a laser with a certain wavelength: perfect for scratching the surface of the supports without altering their external and internal structure.
On the glass, CO2 laser engraving produces an effect called "opacification": it scratches the glass only superficially, vaporizing a part of it but without altering its color or appearance. The product, even the most fragile, remains intact.
CO2 laser engraving offers a number of benefits in terms of versatility, precision and affordability.
The marking is precise and rapid, also ideal for fast flowing lines, such as those where bottles destined for the wine and liqueur market are packaged.
There are no consumables, so process costs are reduced.
The laser source is very long-lived, the machine lasts over time and with minimal maintenance.
On the market there are several companies that offer quality engravers and that allow excellent results.
