532nm green nanosecond laser marking stainless steel moisturizing cup label

The application of laser marking in daily life is very common. The marking principles of different types of lasers are similar. The laser beam of high energy density acts on the surface of various materials, causing them to evaporate or change in color and "engraved". Traces, showing the required etching pattern, text, and other content to be marked, with the characteristics of fast marking, no consumables, no pollution, etc., which can significantly improve the grade of the marked product.

Gifts commonly used in conferences are inseparable from customized markings. The methods of labeling and printing are easy to fall off and blur, which can no longer meet the needs. The high efficiency and high consistency of laser marking make customized services more effective. With the help of the marking software on the PC, you can design graphics and texts with specific meanings, and then mark them on the surface of the specified items through laser marking, you can easily obtain exclusive customized marks.

Take the common thermos cup as an example. The common thermos cups on the market are mostly made of stainless steel, and the outer layer is supplemented by a paint process, which is smooth and not easy to fade, easy to clean, and not easy to slip off when grasping.

Minimizing the thermal impact of the high-energy-density laser beam on the paint surface is inseparable from the "cold" light source 532nm green nanosecond laser. 532nm green nanosecond laser, narrow pulse width (about 25ns), short wavelength, high material absorption rate, high peak power, high load energy ultraviolet photons, marking is "cold" processing, low degree of thermal effect, The heat-affected zone is small, and the specific mark is that the paint surface is not carbonized or ablated, and the pictures and texts are beautiful and clear.

At the same time, the excellent beam quality (M2<1.2) and easy focusing characteristics, the line width of the marking is very small, and the surface marking on the order of microns can be carried out. On display, the overall feel is very flat.

Comparing the mark obtained after laser marking with the computer design, it can be found that the two are basically the same, which reflects the high consistency of laser marking, and the whole process is very fast. For some simple marks, it can be completed in an instant. , the efficiency is very high. The non-contact processing method of laser marking can also protect the body of the thermos, avoiding possible scratches, indentations and dents caused by mechanical stress, improving the overall aesthetics.
