UV laser marking machine belongs to the series of laser marking machine products, but it is developed with 355nm UV laser. The machine adopts the third-order intracavity frequency doubling technology. Compared with infrared laser, the 355 UV light focus spot is extremely small, which can greatly reduce the mechanical deformation of the material and has little processing heat effect. Because it is mainly used for ultra-fine marking and engraving, it is particularly suitable for marking food and pharmaceutical packaging materials, drilling microholes, high-speed division of glass materials, and complex graphic cutting of silicon wafers. Recently, it is very popular to mark leaves only for bookmarks, picture albums and other products, thanks to the function of UV laser marking leaves.
As a natural biological material, leaves are soft and fragile. However, the high-energy UV beam of the UV laser marking machine will not cause obvious damage to the leaves. Compared with traditional marking methods, such as inkjet marking or laser engraving, the UV laser marking machine will hardly produce pressure and friction on the leaves during the marking process, ensuring the integrity of the leaves.
The UV laser marking machine can be adjusted according to the characteristics of the leaves, such as adjusting the laser power, marking speed and the marking pigment used. Therefore, whether it is a tender green new leaf or a dry old leaf, the UV laser marking machine can adapt to different leaf materials and ensure the consistency of the marking effect. In this way, people, animals, or paintings can be combined with leaves to create exquisite gifts for sale.
