355nm Diode Pumped Solid State (DPSS) Lasers can also mark clear glass

Due to the fragile nature of glass, engraving on the surface of glass products requires higher process requirements. Compared with ordinary marking methods, laser marking technology has high processing efficiency, beautiful and detailed marking products, and does not require material consumption, environmental protection, energy saving, and convenient maintenance. It is a common choice for glass product processing. At present, there are the following types of laser marking machines: carbon dioxide laser marking machine, ultraviolet marking machine and green light marking machine. Glass is very easy to break during processing, so special attention should be paid to the marking process.

The laser marking machine is non-contact processing, with short processing time and fine marking lines, which is very suitable for marking patterns or text information on the surface of glass materials. There are several ways to mark glass with a laser.

A common laser marking machine is to use a single laser radiation to produce a mark with an obvious outline on the surface of the glass. After a few days, the laser expands to the area near the original mark to form debris, and then uses multiple radiations to make the area adjacent to the marked area. The areas are heated by thermal conduction, creating a stress gradient in these areas, reducing the possibility of secondary cracking, and this method is very effective in marking soda lime and borosilicate glass. Small glass bottles containing liquid medicines and glass cups in life can be marked with this method.

For the contact laser marking machine, it is a kind of short processing time, can form a thin beam, can realize the fine marking of tempered glass materials, any complex text, graphics, images, trademarks, LOGO, barcode, two-dimensional Code, production batch number, autograph, etc., can be realized by laser marking machine, and any complex text, graphics, images, trademarks, LOGO, barcode, QR code, production batch number, autograph, etc. can be marked by laser Machine marked, fine and beautiful lines, beautiful and generous, very suitable for patterns or text information on the surface of glass materials.
