Classification and Application of Laser Marking Machines

Release time:


Laser marking, as the name suggests, is the use of a laser beam to permanently mark the surface of various substances. Its working principle is to use high-energy density laser to locally irradiate the workpiece, causing chemical and physical changes in the surface material, leaving clear and indelible marks. Laser marking equipment varies depending on the material of the marking product and the application scenario.
Classification of laser marking machines: Marking machines are classified according to laser wavelength, and there are three common types: A. Fiber laser marking machines B. Carbon dioxide (CO2) laser marking machines C. UV laser marking machines (also known as UV ultraviolet light marking machines).
In recent years, with the advancement of technology and the increasing demand for applications, in order to improve production efficiency, small and portable portable laser marking machines and handheld laser marking machines have been developed; A flying laser marking machine that can be integrated into the production line for use; 3D dynamic laser marking machine for surface marking; Visual positioning laser marking machines that can place workpieces freely have emerged. So based on the structure of the marking machine, we can be divided into the following four categories: standard desktop, handheld, 3D, and flying.
Next, let's take a look at several widely used laser devices!
A. Fiber laser marking machine
Fiber laser marking machine is currently a widely used model, using advanced third-generation solid-state fiber lasers. It has stable output power, good beam quality, fast marking speed, good effect, high efficiency, and low energy consumption. It is currently one of the most advanced laser marking equipment. Fiber laser marking machine is suitable for marking, carving, marking, and laser of various metal materials and partially opaque non-metallic materials.
1. Electronic and communication products, integrated circuit chips, computer accessories, and electrical appliances;
2. Various precision parts, automotive and mechanical accessories, hardware tools, instruments, aerospace components;
3. Jewelry, watches, gifts, office supplies, trademark signs, and sanitary ware;
4. The marking of graphics and text in various fields such as tableware, food, beverages, and tobacco and alcohol, as well as large-scale production line operations.
B. Carbon dioxide (CO2) laser marking machine
Adopting the advanced Beijing Dawei laser in China. The entire system has high marking accuracy, fast speed, and stable performance, especially suitable for marking non-metallic materials such as bamboo and wood products, paper, fabric leather, organic glass, epoxy resin, acrylic, unsaturated polyester resin, etc. The body structure design is compact, the lifting platform is stable, the floor area is small, and the space utilization rate is high. At present, CO2 laser marking machines are mainly used in industries such as food and beverage, cosmetics, medicine, cigarettes, electronic components, clothing, and craft gifts.
C. UV laser marking machine
Integrating international advanced technology, high-energy ultraviolet photons directly destroy the molecular bonds on the surface of many non-metallic materials, causing molecules to detach from objects. This method does not generate high heat, and the ultraviolet laser gathers very little light spot, and the processing has almost no thermal impact. Therefore, it is called cold processing, which is suitable for ultra fine marking and carving of special materials.
Mainly used in the high-end market of ultra fine processing, packaging bottles for cosmetics, drugs, jewelry, and other polymer materials are marked with fine effects, firm cleaning of markings, superior to ink coding and pollution-free; Flexible PCB board marking and scribing; Processing of micropores and blind holes in silicon wafers; LCD glass QR code marking, surface punching of glass utensils, metal surface coating marking, plastic buttons, electronic components, gifts, communication equipment, building materials, etc.
