Customers often ask: Do you have a laser marking machine for several products? Or ask why different materials use different laser marking machines? For example, optical fiber is used for metal and carbon dioxide is used for cartons. Is there a universal one?
The difference between laser marking machines is mainly distinguished by lasers. There are UV laser marking machines, CO2 laser marking machines, fiber laser marking machines, semiconductor laser marking machines and other different laser marking machines. The effect of hitting on the material object is different, such as depth, speed, color, thickness, etc.
In fact, it is not difficult to choose a laser marking machine suitable for your product. Since there are many types of laser marking machines, you must first understand the characteristics and application fields of various types of laser marking machines. Choose the most suitable laser marking machine. Next, Beyond Laser will share with you the characteristics and application areas of laser marking machines.
Ultraviolet laser machines rely on laser energy to break the bonds between atoms or molecules, making them vaporize and evaporate into small molecules. Because of its focused spot performance and minimal processing influence area, it can be used for ultra-fine marking and special material marking.
Applications: Mainly used in high-end ultra-fine processing, marking the surface of packaging bottles for iPhone, cosmetics, medicine, food and other polymer materials; marking and scribing on flexible PCB boards; microvias and blinds on silicon wafers Hole processing; LCD liquid crystal glass, glassware surface, metal surface coating, plastic buttons, electronic components, gifts, communication equipment, building materials, etc.
2. Fiber laser marking machine
Fiber laser marking machine uses fiber laser to output laser, and then realizes marking function through high-speed scanning galvanometer system. Fiber marking machine has high electro-optical conversion rate, and can engrave metal materials and some non-metal materials. It is mainly used for depth , For areas with high smoothness and fineness, bitmap marking can be used to mark exquisite patterns on metal, plastic and other surfaces.
Application fields: used in hardware products, tool accessories, precision instruments, glasses and watches, jewelry, auto parts, plastic buttons, building materials, food, medicine, electronic components, integrated circuits (IC), electrical appliances, mobile phones Fast, PVC pipe, sanitary ware and other industries.
The CO2 laser marking machine is a high-performance laser device that expands the laser beam, passes the galvanometer, focuses, and finally controls the deflection of the galvanometer to achieve marking.
Application areas: electronic components, instruments, clothing, leather, luggage, shoes, buttons, glasses, medicine, food, beverages, cosmetics, packaging, electrical equipment, etc. It is also suitable for marking, engraving, hollowing and cutting of various non-metallic materials and products. Various characters, symbols, graphics, images, barcodes, serial numbers, etc. can be marked, engraved, hollowed out, and cut.
4. Green laser marking machine
The green laser marking machine adopts the international advanced cavity design and laser control technology to realize the laser can obtain excellent beam quality under high power operation, high long-term working stability, and narrow laser pulse width. Special intracavity thermal compensation technology and harmonic conversion technology realize high-efficiency frequency multiplication conversion. The green laser marking machine uses YAG crystal as the gain medium to achieve higher single pulse energy at low operating frequency.
Application fields: The equipment can be used for surface processing of most metal and non-metal materials and processing of coating films. Such as hardware, ceramics, glasses, clocks, PCs, electronic devices, various meters, PCB boards and control panels, nameplates, plastics, etc.; suitable for surface and internal carving of glass and crystal products, such as mobile phone screens, LCD screens, and optical devices , Car glass, etc. It is especially suitable for surface treatment such as marking and engraving of high flame retardant materials.
