1. UV laser marking machine

UV marking machine belongs to a series of products of laser marking machines, but it is developed with a 355nm UV laser. Compared with an infrared laser, 355 UV focusing spot is very small, which can reduce the mechanical deformation of materials to a large extent and has little processing heat effect. Because it is mainly used for ultra-fine marking and carving, it is especially suitable for food and medicine Packaging materials marking, microporous, high-speed division of glass materials, and complex graphic cutting of wafer.

2. Green laser marking machine

A green laser marking machine is a kind of laser marking equipment. It is used to carve the surface and interior of glass and crystal products. It is often called a laser internal engraving machine. The green laser is a green laser beam that is produced after laser frequency doubling is pumped by a high-power multimode laser diode.

3. Fiber laser marking machine

Fiber laser marking machine adopts imported laser, equipped with high-speed galvanometer scanning system and professional laser marking software. With the decreasing price of fiber laser, fiber laser marking machine will be the mainstream in the future. Because the fiber laser adopts modular design and an integrated air cooling device, the volume of the fiber laser marking machine is smaller than other laser marking machines. Recently, we have launched a small fiber laser marking machine. Compared with other lasers, fiber laser has higher photoelectric conversion efficiency and better beam quality, so the lines printed by the fiber laser marking machine are more precise. The optical fiber laser marking machine is suitable for marking all kinds of metal and non-metal materials.

4. Semiconductor laser marking machine

The principle of laser marking with diode laser pumped all-solid-state laser (DPSSL) is to use high-power semiconductor quantum well laser instead of a gas lamp to pump solid-state crystal as gain medium laser resonator, so as to generate new wavelength laser, and to generate SHG, THG, and other wavelengths laser by using crystal frequency reserve mixing. Through the design, the whole laser marking technological process, operation procedures, and quality standards from the incoming material re-inspection, part assembly production, process inspection, final assembly debugging to the final product general inspection is established.

5. Lamp pumped YAG laser marking machine

YAG laser is a solid-state laser with a wavelength of 1.064um in the infrared band. Krypton lamp is used as the energy source (excitation source) and Nd: YAG laser is used. Nd (neodymium) is a kind of rare earth element. YAG represents yttrium aluminum garnet. Its crystal structure is similar to Ruby) as the medium of a laser. It can excite the source to emit the incident light of a specific wavelength, which causes the population inversion of the working substance. The laser is released through the energy level transition, and the laser energy is amplified, shaped, and focused to form a usable laser beam.

6. CO2 laser marking machine

CO2 laser marking machine uses a laser beam to make permanent marks on different material surfaces. The effect of marking is to expose the deep material through the evaporation of the surface material, so as to carve exquisite patterns, trademarks, dates, logos, or words. At present, the CO2 laser marking machine is mainly used on some occasions requiring more fine and higher precision. It is used in food, medicine, wine, electronic components, integrated circuit (IC), electrical appliances, mobile communication, building materials, PVC pipes, and other industries. The main advantage of CO2 laser marking machine and inkjet printer is that there is no consumables and permanence
