En el Abierto de Francia de bádminton de 2022 celebrado no hace mucho tiempo, los eventos de dobles mixtos y de individuales femeninos de China cumplieron con las expectativas y ganaron el campeonato, lo cual es muy emocionante. Después del juego, varios jugadores campeones publicaron fotos con el trofeo en las redes sociales PO, lo que atrajo a los internautas de todos los ámbitos de la vida para darles me gusta y felicitarlos.
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.
In order to make the marked lines more delicate, it is necessary to rely on the beam quality. The beam quality of the 355nm UV nanosecond laser is excellent (M2<1.2), and the diameter of the spot after focusing is very, very small, thinner than a hair, which makes it easy to print When marking, the line width can be at the micron level, the details are directly filled, and the contrast of the marker is very high.
