Glass and crystal engraving

Engraving glass with a Laser avoids the risk of breaking the product or the tool. This contactless technology ensures a safe engraving, even on the thinnest glass and it is noiseless.

However, cracks naturally appear when glass is lazed, mostly depending on the glass quality (crystal is usually crack free). To reduce that, we recommend laying a small wet paper on the glass processed area before lazing it. This will improve the heat dissipation and therefore reduce cracks effects. When using this technique, do not forget to turn off the air assist to avoid drying the paper.

By playing with the focal distance and laser power, different aspects can be obtained with laser. Depending on the result you want, the laser parameters will be adapted automatically thanks to our Gravostyle™ software library.

It allows the user to process:

• white engraving
• deep engraving with the possibility to add colour inside after (see Gravotech colourants catalogue)
• frosted engraving
• light unpolished engraving

Depending on the pressure applied on the glass, the engraving can be deep enough to be filled with colour or it can be light and create a depolish effect that only affect the surface of the glass.

Mechanical engraving machines are cheaper than lasers, moreover, as there is no need for an air exhaust (contrary to the laser) the using cost is very low and the return on investment is faster.

Mechanical engraving is a compact solution and designed to be used in-shop. They are very popular to personalise small items like flasks live to create an unforgettable moment for your customers.

Mechanical engraving machines can be easily upgraded to open new possibilities, for instance with a rotary device to engrave on circular items or with a lubricant tray to retrieve glass dust carried by the lubrication system.
