Glass laser marking and engraving machine correctly choose uv laser marking laser

Why are UV laser marking machines often used for higher-end products? And what about those flammable materials that people think can also be marked with UV lasers? In fact, we need to be able to understand the characteristics of ultraviolet lasers. When the ultraviolet laser processes the surface of the material, it is actually a kind of cold processing. Just like the infrared laser, the material molecules move to generate heat, thereby increasing the temperature of the material to achieve melting. For flammable materials, it is difficult to achieve high-quality marking effects, and it is generally difficult to adapt to them. The processing of materials by ultraviolet lasers directly breaks the molecular chemical bonds to achieve the purpose of marking processing without generating any heat or heating. Therefore, it is widely used in high-end products, or product materials with high quality of appearance processing.

However, the laser processing of glass can be regarded as a kind of handicraft processing. Fashion and beautiful glass marking is widely welcomed, and the process that can achieve clear and permanent is more attractive. For processing, only UV laser marking machine is the most suitable choice.

Previously, traditional glass patterns were mainly screen-printed. For some tempered glass, the pattern is first screen printed (high temperature ink) and then tempered, so that the printed pattern is relatively firm, but the disadvantage is that the color registration is not good, and the colors are relatively small; there is another kind of screen printing is tempered After printing (low temperature ink), the operation is relatively simple, and the cost is lower than that of high temperature ink, but the disadvantage is that the adhesion is slightly worse.

No matter which method is used, there are disadvantages such as long processing cycle, high cost, poor edge effect, insufficient durability, complex process, environmental pollution, and harm to human body, which make the traditional processing method out of date.

However, UV laser marking machines are now the most in short supply choice for glass marking patterns. Contrary to the traditional method, laser processing is very fast and accurate, graphics can be customized by computer programming, and it is environmentally friendly and healthy, with low consumables. Therefore, laser has become a new processing method for glass marking.

The reason why RFH UV laser marking machine can be widely trusted in the glass product industry is due to the high-end performance and marking effect of the equipment. Its equipment accounts for 53% of the domestic UV laser equipment marking sales. In terms of application performance, the main advantages of UV laser marking are reflected in the following aspects.

Several advantages of UV laser marking machine:

1. Modular design, flexible application, equipped with automatic/manual working mode;

2. Equipped with a violet laser, with excellent performance, uniform laser power density, fine spot, and stable output optical power;

3. The heat-affected zone is small to avoid damage to the processed material, and the yield is high;

4. Wide range of applicable materials, make up for the lack of infrared laser processing ability, and can realize ultra-fine laser marking;

5. No consumables, low cost of use and maintenance.
