Why UV laser marking machine more and more popular in the market?
UV Laser Marking Machine does not damage the surrounding surface area while marking. This significant feature ofthe UV Laser Marking Machine thus enables maximum output in marking.
UV laser markers operate at a 355 nm wavelength. They use ultraviolet light to deliver exact, ultra-defined markings on materials. The UV laser’s wavelength is one-third the size of a standard laser’s wavelength, creating superior detail work during marking. A standard 1064 nm wavelength laser is passed through several nonlinear crystals to achieve this laser beam size. As the beam travels through each crystal, it decreases in size until it achieves the 355 nm wavelength.
With such a small beam, there is minimal heat stress on materials — this marking process using
UV lasers is called “cold marking.” The UV light breaks the bonds between the material’s atoms and molecules, preventing the overheating seen with other laser markers.
Advantages: These highly versatile laser markers offer exceptional performance on a wide range of organic and inorganic materials. With low power requirements, long life spans and generally minimal maintenance requirements depending on factors like usage, UV lasers deliver precision without sacrificing efficiency.

Application
1. Plastics
UV laser marking performs well on a variety of plastic products. Compared with other types of laser marking, UV laser has shorter wavelength and higher energy density, so it is better for marking many plastic materials, such as polyurethane, polyethylene, polypropylene, etc. It can achieve high contrast marking without causing melting or deformation of the material.
2. Metal
Compared to other types of laser marking, UV laser marking on metal materials is more effective. The short wavelength of the UV laser enables it to overcome the high reflectivity of metals and achieve high-resolution marking without excessive thermal impact on the material.
3. Glass
UV laser marking for glass allows for high precision and high contrast marking. Compared to other laser types, UV lasers are able to interact better with glass materials to create clear and durable markings. This makes UV laser marking widely used in the production of glass products such as displays, glassware and glass decorations.
4. Ceramics
Due to the short wavelength and high energy density of the UV laser, it is able to achieve fine marking on ceramic materials. Whether it is ceramic tiles, ceramic tableware or ceramic decorations, UV laser marking is able to create long-lasting and clear patterns or text on the surface.
UV lasers excel in creating high contrast marks on plastics materials, including PP (polypropylene), PC (polycarbonate), PE (polyethylene), ABS, PA, PMMA, silicon. Additionally, UV lasers offer the advantage of generating non-damaging marks, ensuring the integrity of the marked surface.
