As consumption continues to upgrade, product customization services are also increasing. Nowadays, office stationery such as rulers, staplers, and knives are personalized by laser marking, which not only easily obtains exclusive personal labels, but also adds a full sense of technology.
In the customized production of office stationery, the high-energy-density laser beam output by the laser acts on some areas of the stationery. In a very short period of time, some components on the surface of the plastic itself are instantly vaporized or changed in color, so that the non-active area appears. The logo is formed by color difference.
Considering that the materials of office stationery include plastic and metal, etc., the 355nm UV nanosecond laser can do the job. With the help of the material's high absorption rate and high single-photon energy characteristics of 355nm ultraviolet light, it is easier to destroy the chemical bonds connecting the atomic components of the substance. This "cold" processing method does not heat the periphery of the processing, and the thermal effect is small. The marking presents high-quality graphic information without carbonization, burning, and melting. The "cold" processing characteristic is also one of the very significant differences between the 355nm ultraviolet laser and the 1064 infrared laser in marking.
Moreover, the 355nm ultraviolet light is easy to focus. Under the excellent beam quality (M2<1.2), the diameter of the focused spot reaches the order of microns. It is easier to mark with narrow line width and high resolution in a small area during marking. For example, marking student names, student numbers, classes, and even other graphic information such as flowers, landscapes, cultural landscapes, etc., the entire marking process is very efficient.
Another feature of laser marking is that the touch of the mark is very subtle. It seems that the touch is obvious. When you touch it, it is difficult to feel the gap between the mark and the surrounding material, which means that laser marking is just "peeling off". "A shallow layer on the surface of the material, compared with the traditional ordinary silk screen and heat transfer printing, not only has a more technological sense, but also is not afraid of falling off, blurring, abrasion, permanent
