Engraving wood trophies by RFH 355nm uv laser diode module

At the 2022 French Badminton Open held not long ago, China's mixed doubles and women's singles events lived up to expectations and won the championship, which is very exciting. After the game, several champion players posted photos with the trophy on social media PO, which attracted netizens from all walks of life to like and congratulate them.

Careful netizens found that the championship trophy at the French station seems to be different from the usual ones. From the photos, the material (probably) is made of wood, with blue materials on both sides as a foil. The wooden surface is also marked with badminton events. The information is refreshing.

What type of laser is suitable for marking wood

In fact, it is still very common to make trophies out of wooden materials. It is light enough, environmentally friendly enough, and the texture is not inferior to metal. Using laser marking, high-quality marking can be carried out on the surface of wooden trophies to improve the grade of trophies.

In the choice of laser for marking, the 355nm ultraviolet light output by the 355nm ultraviolet laser has a short wavelength, high single-photon energy, and high material absorption rate. Its cold processing characteristics can well "restrain" the low ignition point of wood. It is not easy to burn and carbonize. When marking, the beam emitted by the laser passes through the high-speed galvanometer to scan the marking head, and the focal point of the laser moves on the surface of the wooden material according to the required requirements. At this time, it also fully reflects the high flexibility of laser marking. , The different shapes of the text can be marked after setting on the PC software. At this time, the high-energy-density laser beam coming out of the marking head makes the surface layer of the wood material quickly evaporate and detach, and moves with the set marking route, leaving a permanent mark. Of course, this kind of mark only removes a very shallow layer of material, but it is very clear visually, and there is a uniform and smooth touch when touched, and the texture of the mark emerges spontaneously.

Um die markierten Linien filigraner zu machen, ist es notwendig, sich auf die Strahlqualität zu verlassen. Die Strahlqualität des 355-nm-UV-Nanosekundenlasers ist ausgezeichnet (M2 < 1,2), und der Durchmesser des Flecks nach dem Fokussieren ist sehr, sehr klein, dünner als ein Haar, was das Drucken erleichtert. Beim Markieren kann die Linienbreite sein Auf der Mikrometerebene werden die Details direkt gefüllt und der Kontrast des Markers ist sehr hoch.
