Application of fiber laser marking machine in glass industry

Glass is an amorphous body. The molten glass cools rapidly, and each molecule does not have enough time to form a crystal to form the glass. And the fiber laser marking machine uses three kinds of craftsmanship on the glass.

Multiple laser radiation method: Use a single laser radiation to generate a symbol with a clear outline on the surface of the glass. After a few days, the laser expands to the area around the original symbol to form fragments. Heating, and then reducing the possibility of secondary fracture, this method is very effective for marking on soda lime glass and borosilicate glass. One-time laser radiation is more effective for marking on fused silica glass and quartz glass, because the expansion coefficient of these two materials is very low.

Discrete dots to form a ring-shaped crack method: use a series of ring-shaped cracks to form text, bar codes, square or rectangular codes, and other shape code pictures. There are more CO2 laser marking machines that use this method, and the CO2 laser marking machine sets a parameter for marking and coding on the glass and there are fewer cracks. Discrete points appear to form annular cracks. Low-density ring-shaped cracks occur in the glass after heating and cooling cycles. When the glass is heated, it swells and kneads the surrounding materials. When the temperature rises to the softening point of the glass, the glass quickly swells to form a low-density dome that protrudes from the glass surface. Handheld fiber laser welding machine

Crack-like appearance cracking method: select heating and cooling processes to change the appearance of the affected glass. This method is not immediately visible. It starts to occur along the laser symbol area after a little pressure.状Crack. This method can print clear symbols on high-quality car glass, and its requirements are pure appearance.

The 21st century is the age of optical fiber. Laser, as one of the sharp weapons of the age, has unparalleled advantages in many occupations. With the development of science and technology and the popularization of use, the scope of application of fiber laser marking machine has been quietly used to all aspects of people's lives. Due to the advancement of customers' anti-counterfeiting awareness, the previous coding-style marking method has not gained the trust of customers. Marking machines are very popular for displaying batch number, production date, production trademark and other information in various pictures. The use of glass products is not far behind. Beer bottles, cosmetic bottles, and beverage bottles are all glass products. This has also prompted many glass manufacturers to introduce laser marking machines to mark items. It can be seen that the use of fiber laser marking machine has brought rapid development to the market, and it also shows the progress of an era. 3d laser marking machine.
