high power uv laser source for engraving glassware

A good laser marking machine company tells you that the current customized Logo on the surface of glassware is mainly realized by sandblasting process (please refer to Encyclopedia) and Co2 laser engraving (please refer to Encyclopedia).

The sandblasting process has a fast processing speed and is suitable for mass production. The disadvantage is that the sandblasting decal paper needs to be customized in advance, the waiting period is long, and it is laborious and labor-intensive in the case of fragmented orders and small orders; in terms of effect, the patterns processed by the sandblasting process Not fine enough, especially the edges of the pattern are not smooth enough, rough with irregular protrusions; in addition, the sandblasting process produces a lot of consumables, which is not environmentally friendly;

The CNC Co2 laser engraving machine can complete the engraving of any Logo according to the vector diagram, which is more flexible in small batch customization, but the speed of Co2 glass engraving is slower than that of the sandblasting process, and the engraving pattern is not fine enough;

Similar to carbon dioxide laser engraving, UV laser marking machine uses CNC high-energy laser beam to process the glass surface, which is flexible and convenient, and can print any vector diagram on glassware in real time; different from Co2 laser engraving machine, UV laser marking machine uses Compared with the Co2 laser, the UV laser in the 355nm band has a smaller focusing spot diameter (1.2 wire, 12um, which is 1/15 of the Co2 laser focusing spot diameter), and the lines depicted are finer and the photon energy of the UV laser is higher. High, the photon energy directly breaks the molecular chain between the glass crystal molecules, and directly completes the peeling of the glass surface material. The processing effect is similar to that of frosting, the logo is fine, the edge is smooth, and the hand feel is good; while the Co2 laser heats the glass surface by laser beam energy. Substance, which melts and evaporates the surface substance, is a thermal processing method, which is easy to leave large cracks on the surface and affect the fineness of the engraving;

According to industry rules, the dimensional tolerance of 1mm is allowed in the glassware manufacturing process. For the sake of beauty, glassware is also designed into various exquisite irregular shapes. The size, shape and position of the logo or customized pattern printed by the customer are also very strange. In addition, how to increase production capacity, reduce unit product cost and how to balance between quality and productivity are also the pain points that major companies are concerned about, etc., which pose severe challenges to the entire UV laser marking system; generally applicable to UV laser marking systems for a wide range of other industrial applications will not be up to the challenge if they are not optimized and retrofitted.
