Customers often ask: Do you have a laser marking machine for several products in your home? 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 ultraviolet laser marking machines, CO2 laser marking machines, fiber laser marking machines, semiconductor laser marking machines, and other different laser marking machines to mark objects of different materials. The effect is different, such as depth, speed, color, thickness and so on.
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 before you can choose the most Suitable laser marking machine. Next, Chao Mi Laser will share with you the characteristics and application areas of laser marking machines.
1. Ultraviolet laser marking machine
The ultraviolet laser machine relies on laser energy to break the bonds between atoms or molecules, so that they become small molecules and vaporize and evaporate. Because of its focused spot performance and minimal processing influence, it can be used for ultra-fine marking and special material marking.
Application areas: Mainly used in ultra-fine processing of high-end, iPhone, cosmetics, pharmaceuticals, food and other polymer materials packaging bottle surface marking; flexible PCB board marking, scribing; silicon wafer micro-hole, blind hole processing; LCD liquid crystal glass, glassware surface, metal surface coating, plastic buttons, electronic originals, gifts, communication equipment, building materials, etc.
2. Fiber laser marking machine
The fiber laser marking machine uses a fiber laser to output the laser, and then passes through a high-speed scanning galvanometer system to achieve the marking function. The fiber marking machine has a high electro-optical conversion rate, and can engrave metal materials and some non-metal materials. It is mainly used for depth and smoothness. , For high-precision areas, bitmap marking can be used to mark exquisite patterns on metal, plastic and other surfaces.
Application areas: used in hardware products, tool accessories, precision equipment, glasses and watches, jewelry, auto parts, plastic buttons, building materials, food, medicine, electronic components, integrated circuits (IC), electrical appliances, mobile communication, PVC Pipe, sanitary ware and other industries.
3. CO2 laser marking machine
The CO2 laser marking machine passes the laser beam through beam expansion, galvanometer, focus, and finally realizes marking high-performance laser equipment by controlling the deflection of the galvanometer.
Application areas: electronic components, instrumentation, clothing, leather, bags, 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. Laser marking machine
The laser marking machine adopts the international advanced resonant cavity design and laser control technology to realize that 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 laser marking machine uses YAG crystal as the gain medium to achieve higher single pulse energy at low operating frequency.
Application field: The equipment can be applied to the surface processing of most metal and non-metal materials and the processing of coating films. Such as hardware, ceramics, glasses, clocks, PCs, electronic devices, various instruments, PCB boards and control panels, nameplate display boards, 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.
The above types of laser marking models basically cover the marking of all materials on the market. The most practical method is to bring samples to test samples, and select cost-effective and high-quality models based on specific results.
