Why is it best to use  UV (short wavelength) lasers to mark glass?

We all know that glass is fragile and should be handled with care during use and transportation. But I am curious how some of the beautiful patterns are carved into the glass. This is about the laser marking machine. Ultraviolet laser marking machine is very suitable for marking and engraving glass surface, and can achieve ultra-fine production. Ultraviolet laser marking makes up for various shortcomings such as low processing accuracy, difficulty in drawing, damage to workpieces, and environmental pollution in the past. With its unique processing advantages, it has become the new favorite of glass product processing, and is listed as a must-have in various wine glasses, craft gifts and other industries. machining tools.

Glass material date marking chooses  UV (short wavelength) lasers marking for better opportunities

First, the wavelength of the  UV (short wavelength) lasers marking machine is 355nm. The extremely small wavelength determines that it has high beam quality, small focusing spot, and can achieve ultra-fine marking requirements for glass products. Its small characters can reach 0.2mm.

Second, the  UV (short wavelength) lasers marking machine has a relatively high absorption rate for various materials, which means that it can be used on a variety of different materials, including glass, metal and special materials. .

Third, the thermal influence of the  UV (short wavelength) lasers marking machine on the object to be processed is negligible. When the heat-affected area is small, there will be no thermal effect, and there will be no material deformation or material deformation due to excessive laser beam energy. It is the occurrence of scorch.

Fourth, in the appearance design, the up and down sliding door closed processing is adopted, and the high-quality special filter protective plexiglass is used to make a special observation window, which has created excellent protection performance for the ultraviolet laser marking equipment.
