UV laser marking machine

UV laser marking machine is a series of products of laser marking machine, but it is developed by using 355nm ultraviolet laser. Compared with infrared laser, this machine uses third-order intracavity frequency doubling technology. The 355 ultraviolet light focusing spot is very 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 carving, it is especially suitable for marking and microporous marking of food and medical packaging materials High-speed division of glass materials and complex graphic cutting of silicon wafers.

Product Description


UV laser marking machine is a series of laser marking machines, so the principle is the same as that of laser marking machine, which is to use laser beam to make permanent marks on different material surfaces. The marking effect is to directly break the molecular chain of the material through short-wavelength laser (different from the evaporation of the surface material produced by long-wavelength laser to reveal the deep material), so as to display the required etching patterns and characters.

UV laser can be used for ultra-fine marking and special material marking due to its small focus spot and small processing heat-affected area. It is the preferred product for customers with higher requirements for marking effect. In addition to copper, UV laser is suitable for processing a wider range of materials. Not only the beam quality is good, the focus spot is smaller, and ultra-fine marking can be realized; The scope of application is wider; The heat affected area is very small and will not produce thermal effect and material burning; Fast marking speed and high efficiency; The whole machine has the advantages of stable performance, small size and low power consumption.

Advantages of UV marking machine

Generally speaking, our traditional laser marking machine (optical fiber laser marking machine, co2 laser marking machine) mainly uses the thermal effect of laser to burn the material surface to form a color change or vaporize the material surface layer to leak the underlying material to form a mark. However, this mark formed by thermal effect has great defects in the soft film packaging industry. Carbon dioxide hitting the soft film will easily cause the soft film to break down and leak, thus affecting the shelf life of food. There is no response when the optical fiber laser hits many plastic films, and the focal depth of the optical fiber (only one millimeter) is easy to be illegible when the bag shakes or warps. The appearance of purple light perfectly solves the above problems. The ultraviolet laser marking machine uses 355 nm short wavelength ultraviolet laser, which is very good for soft film absorption. The principle of ultraviolet laser marking machine is that 355 nm ultraviolet light irradiates the coating on the surface of the soft film, causing chemical changes in the layer, thus producing color changes. Because ultraviolet light only reacts with the coating, it will not break through the soft film packaging.
