At present, 44.3% of lasers are used in the field of enterprise processing, and ultraviolet lasers are famous for their fine processing, and have become another mainstream laser of fiber lasers. Why can UV lasers be rapidly applied in various micro machining fields? What are its advantages in the market? What are the unique properties of industrial micromachining applications?
Solid state ultraviolet laser
Solid state ultraviolet lasers can be divided into xenon lamp pumped ultraviolet lasers, krypton lamp pumped ultraviolet lasers and new laser diode pumped all solid state lasers according to pumping modes. The integrated design is generally adopted, which has the characteristics of small light spot, high repetition rate, reliable performance, strong heat dissipation ability, good beam quality and stable power.
Common UV laser marking
In our daily life, we will come into contact with all kinds of trademark signs, metal or non-metal, some in words and some in patterns, such as Midea logo, mobile phone Apple logo, keyboard keys, mobile phone keys, cup graphics and text, production date of cans and so on. At present, many of these signs are realized by marking with ultraviolet lasers. The reason is very simple. UV laser marking is fast and has no consumables. Through the optical principle, permanent marks can be printed on the surface of various substances, which is very helpful for anti-counterfeiting.
Application area
The ultraviolet laser has the advantages that other lasers do not have, which can limit the thermal stress, reduce the damage to the workpiece and maintain the integrity of the workpiece during processing. At present, UV lasers are applied in the field of enterprise processing, mainly in four fields: glass technology, ceramic technology, plastic technology and cutting technology.
1. Glass technology
Glass marking can be applied to the packaging of glass bottles in wine bottles, condiment bottles, beverage bottles and other industries, as well as the manufacturing of glass gifts and crystal marking.
2. Laser cutting
UV laser equipment can be applied in many fields of flexible board production, including FPC shape cutting, contour cutting, drilling, covering film window opening, soft and hard bonding plate cover and trimming, mobile phone case cutting, PCB shape cutting, etc
3. Plastic marking
Application scope: most general plastics and some engineering plastics, such as PP, PE, PBT, pet, PA, ABS, POM, PS, PC, pus, EVA, etc., can also be used for plastic alloys such as; PC / ABS and other materials, the laser marking handwriting is clear and bright, and black and white handwriting can be marked.
4. Ceramic carving
Application scope: tableware ceramics, vase ceramics, building supplies, ceramic sanitary ware, tea ware ceramics, etc. UV laser ceramic marking has high peak value and small thermal effect. It has natural advantages over similar fragile ceramics, such as etching, engraving, cutting is not easy to damage components, the process is fine, and the waste of resources is reduced.
In recent years, the market trend of UV lasers in China has shown a continuous upward trend, which reflects the application and development trend of UV lasers in China. Riselaser is a manufacturer focusing on laser parts integration. According to the feedback information of the market and users, the UV laser market is developing towards higher power, shorter pulse picosecond and femtosecond higher repetition rate.
