Laser marking solution for glass products

Jan 14, 2020

Glass is a transparent solid at normal temperature. It forms a continuous network structure during melting. During cooling, the viscosity gradually increases and hardens without crystallizing silicate non-metallic materials.


Types and applications

The glass we use is made of quartz sand, soda ash, feldspar and limestone through high temperature. A non-crystalline solid material obtained by gradually increasing the viscosity of the melt during cooling. Brittle and transparent. There are quartz glass, silicate glass, soda lime glass, fluoride glass, high temperature glass, high pressure resistant glass, UV-resistant glass, explosion-proof glass, etc. 威廉希尔官方下载ually refers to silicate glass, which is made of quartz sand, soda ash, feldspar, limestone, etc., after mixing, melting at high temperature, homogenizing, processing and forming, and then annealing. Widely used in construction, daily use, medical, chemical, electronics, instrumentation, nuclear engineering and other fields.


The development of the glass industry originated from European and American countries. In recent years, the production capacity of glass companies in China has expanded rapidly, and the production capacity has been comparable to that of the United States, Germany and other countries. With the international glass industry gradually shifting to China and the R & D and production capacity of Chinese local enterprises In the next few years, China will become one of the most important glass production bases in the world.


威廉希尔官方下载Common glass processing technology

Etching method: 威廉希尔官方下载e chemical agent-hydrofluoric acid to corrode glass. First, melt and cover the glass with paraffin, engraving the pattern on the surface of the paraffin, and then apply hydrofluoric acid before washing the paraffin. Because hydrofluoric acid is volatile and polluted seriously, a protective layer is needed and the operation is complicated.


Thermal processing: Thermal processing is used to improve the appearance quality of processed materials, mainly flame cutting, fire polishing, drilling and so on. However, glass is highly brittle and easily cracks due to high temperature, which damages the material.


威廉希尔官方下载Screen printing: The principle of screen printing is to print the ink on the surface of flat glass, and then use the curing measures of the ink to make the pattern firm. However, the screen printing process is complicated, the ink is harmful to the human body, and the screen printing does not register well, with fewer flowers and poor coloring.


威廉希尔官方下载UV laser marking: Laser marking is a photo-motor integrated device controlled by a software system. The graphics are controlled by software, and non-contact processing is adopted to prevent the glass from being damaged by external forces. And the UV laser marking is cold processing, the beam quality is high, and the light spot is very small, which can achieve ultra-fine marking of glass.
