Glass products are widely used in various fields such as construction, daily life, chemicals, home furnishings, electronics, instruments, and nuclear engineering. Due to its fragility, careful handling is required when marking glass surfaces. Laser marking machines can perform processing without physical contact, are fast, and produce detailed results, making them ideal for marking patterns or text on glass.
1.Marking by Laser on the Glass Surface
This method involves using a laser to create clear markings on the glass surface. After a few days, the surrounding area of the markings will disintegrate into fragments. By repeatedly irradiating, heating the adjacent areas of the marked region, and creating a stress gradient, the risk of secondary cracking can be reduced. This method is particularly suitable for soda-lime glass and borosilicate glass, such as small glass bottles and cups used for storing liquid medications in daily life.
2.Crack Formation at Discrete Points
A series of ring-shaped cracks can be used to form text, barcodes, square or rectangular code patterns, and other shaped code patterns. CO2 laser marking machines are typically used for this operation because they produce fewer cracks when setting glass markings and coding parameters. Discrete points will form ring-shaped cracks, and the density of the glass surface can be altered through heating and cooling cycles. Using a CO2 laser marking machine, businesses can create exquisite patterns on glass surfaces, enhancing the quality of the glass.
3.Crack Formation by Surface Change
The density of the affected area on the glass surface is altered through heating and cooling processes, which are not immediately visible but will cause cracks along the laser-marked areas when slight pressure is applied. The cracked glass surface can produce an ice-crack pattern that is opaque. This method is widely used in interior decoration, such as partitions and background walls, and can also be used in glass furniture, making it popular with consumers.
