What are the advantages of nanosecond UV laser marking glass

With the improvement of people's living standards, there are higher requirements for various substances. Glass can be said to be the most common things in daily life, such as mirrors, bottles, cups, tableware and so on. At the same time, glass is also a common and exquisite work of art. Whether it is home decoration, office decoration, store decoration and other places, its application can be said to be various, adding an artistic beauty to life. Moreover, glass has been widely used in the market due to its variable shape, good impact resistance and controllable cost.

Today's glassware is no longer just practical to meet people's needs in the past, and glass craftsmanship is a hot topic in the market. For example, it is used in commercial and entertainment places such as shopping malls, hotels, restaurants, etc., engraved pictures, cups, plates, etc., which are transparent and opaque, with obvious three-dimensional layering and elegant decorative effect. And such exquisite works of art are no longer the past, and can only be engraved during firing. With the use of lasers, you can engrave your desired pictures on the finished glassware, which greatly accelerates the glass process. process.

Glass is not difficult to understand, transparent and crystal clear, an indispensable art in life. At the same time, it is brittle and brittle when touched, which is a big difficulty for machining. The traditional mechanical glass process method is to make patterns or patterned glass by chemical corrosion. The working time is long, the efficiency is low, and it is easy to cause damage to the equipment. This is a limitation of the traditional process, but UV laser marking can make up for it. at this point.

Ultraviolet laser marking technology adopts non-contact processing and software-controlled graphics generation. It can protect fragile products from external force damage. The output power is 1W-5W, the wavelength is 355nm, and the spot is 0.7mm. It is a cold light source and has a narrow pulse width. , The beam is fast, easy to integrate, suitable for pattern or text information marking on the surface of glass materials.

It can be simply understood that laser marking glass products refers to the use of computer control technology as the basis, and the laser micro-processing medium makes the glass optically vaporize during the laser work, so as to achieve the purpose of engraving patterns. So what are the characteristics of UV laser in glass processing? Through repeated testing of UV lasers on glass products, the following conclusions have been drawn, hoping to help everyone better understand the application of UV lasers to glass technology.

1. The temperature is low, and there will be no coke and deformation due to high temperature during the proofing process.

2. High efficiency, the proofing time is short, and the efficiency is faster than mechanical proofing, dozens or hundreds of times.

3. The laser has good directionality, stable light output, and can accurately perform micro-processing, which is difficult for other instruments to achieve.

4. It will not have excessive wear and tear on the glassware, nor will it affect the properties of the glass.

5. Ultraviolet laser proofing will not produce a lot of pollution, which is conducive to environmental protection.

6. Laser proofing is easy to achieve automation and streamlined operations.

7. It can be engraved inside the glass without damaging the surface material of the glass.

8. Glass cutting, this energy heats a specified part of the workpiece to a pre-defined temperature for segmentation.

9. Glass drilling, through more than 100,000 pulses per second, high energy is generated to instantly vaporize the glass material.
