3D Laser inner engraving machineWith the rapid development of today's society, the types and uses of glass are becoming more and more diverse, and there are more and more manufacturing processes. Today, I want to talk to you about a revolutionary change in the deep processing of craft glass - 3D laser engraving glass technology. Glass manufactured by 3D laser engraving glass technology is also called laser engraving glass or engraving glass.

What is the formation principle of laser engraving glass?

For laser engraving glass, its energy density must be greater than a certain critical value or threshold value that destroys the glass, and the energy density of the laser somewhere is related to the size of the spot at that point. The same laser, the smaller the spot is generated. the higher the energy density. With proper focusing, the energy density of the laser can be made below the glass destruction threshold before entering the glass and reaching the processing area, and exceeding this threshold in the desired processing area. The laser generates pulses in a very short time with energy capable of The heat ruptures the crystal in an instant, creating tiny white spots that carve a predetermined shape inside the glass, while the rest of the glass or crystal remains intact. At the same time, this technology can also be used in glassware or other products in the glass industry.

What are the advantages of laser engraving glass?

1. Energy saving:

The laser used is generally 2 watts to 5 watts, that is, the laser consumes 2-5 kWh of electricity for 1,000 hours of operation. Even if the transmission parts are added for one hour, it only consumes 1 kWh of electricity. This is different from traditional sandblasting engraving and craft screen printing. It requires a dozen or 30 to 40 kilowatts of electricity, which is a world of difference.

2. Environmental protection:

Laser engraving is to use a laser beam to engrave inside the glass, no dust, no volatile substances, no emissions, no consumables, and no pollution to the external environment, which is fundamental to traditional sandblasting, screen printing, and pickling. Incomparable, and the working environment of workers can be greatly improved.

3. High degree of automation:

After the processing object is placed in place, the entire production process is controlled by the computer, with a high degree of automation. Compared with the traditional sandblasting carving process, the labor intensity of workers is greatly reduced. Therefore, the production of laser engraved glass is relatively easy to achieve standardized, digital, and networked production, and can also implement remote monitoring and operation, with low overall costs.

4. Product dual function

Combined with LED lighting, the product image is actively illuminated, beautiful, and has the dual functions of advertising decoration and lighting

The purpose of laser engraving glass and the significance of 3D laser engraving glass technology.


Laser engraved glass is a new type of building material based on electronic technology, laser technology and LED technology. It is mainly used for shower room, deep processing of sliding doors, KTV, bars, tea restaurants, chain stores and other night market partition and background applications, daily necessities and art photo viewing, as well as industrial glass production design.


The emergence of 3D laser engraving glass technology not only greatly improves the technological development of the ceramic industry, but also has a profound impact on the development of the entire building materials industry. Laser engraving glass will be a revolutionary change in the glass deep processing industry. It is energy-saving, environmentally friendly and highly automated. It can realize standardized, digital and networked production, and can also realize remote monitoring and operation, which greatly reduces the labor intensity of workers. And improve the working environment, greatly improve the production efficiency and product quality, is an ideal upgrade of traditional glass processing technology.
