20 and 35 watts Green laser ultra-fine beam marking glass products

Glass products are widely used in construction, daily use, medical, chemical, household, electronics, instrumentation, nuclear engineering and other fields. Glass is fragile, so engraving on the surface of glass products requires high craftsmanship. 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 use laser to mark glass.

Multiple laser irradiation

A laser radiation is used to produce a clear mark on the surface of the glass. A few days later, the laser expands to the area near the original mark to form fragments, and then uses multiple radiations to heat the area adjacent to the marked area through thermal conduction, so that these areas are formed. Stress gradient, thereby reducing the possibility of secondary fracture, using this method to mark on soda lime glass and borosilicate glass is very effective. Small glass bottles containing liquid medicines and glasses in life can be marked with this method.

Discrete point forming ring crack method

A series of ring-shaped cracks are used to form text, bar codes, square or rectangular codes and other shape code patterns. Generally, green laser marking machines use this method, and green laser marking machines set a parameter for marking and coding on the glass and produce fewer cracks. Discrete points appear to form ring-shaped cracks. The glass produces low-density ring-shaped cracks through heating and cooling cycles. When the glass is heated, it expands and squeezes the surrounding materials. When the temperature rises to the softening point of the glass, the glass rapidly expands to form a low-density material that protrudes from the glass surface.

Using the green laser marking machine, businesses can mark exquisite patterns on the surface of the glass to reduce the grade of the glass.

Crack-like surface cracking method

The process of heating and cooling is used to change the surface of the glass that is affected. This method is not immediately visible, but only after a little pressure does it start to produce turtle-shaped cracks along the laser marked area. Cracked surface glass not only has the properties of safety glass, but also has the effect of ice cracking and non-full transparency. Therefore, it is widely used in interior decoration, such as partitions, background walls, and can also be used for glass furniture, and is deeply loved by consumers.
