UV laser marking machine

The laser marking machine can mark the surface of products of different materials, and special laser products can realize stainless steel color marking, aluminum oxide black marking and other processes. The common laser marking machines on the market now include CO2 laser marking machines, fiber laser marking machines and ultraviolet laser marking machines. The main differences between the three laser marking machines are the different lasers, laser wavelengths and application fields. Let's follow the editor to understand the specific differences between CO2, optical fiber, and ultraviolet laser marking machines.

The differences between optical fiber, carbon dioxide and UV laser marking machines are as follows:

1.Different Lasers:

Fiber laser marking machines use fiber lasers, carbon dioxide laser marking machines use CO2 gas lasers, and ultraviolet laser marking machines use short-wavelength ultraviolet lasers.

UV laser is a very different technology from CO2 and fiber laser technology, UV laser is also known as blue laser beam, this technology has low heat engraving ability, it does not heat the material like fiber and CO2 laser marking machines The surface belongs to cold light engraving.

2.Different Laser wavelengths:

The laser wavelength of the fiber laser marking machine is 1064nm, the laser wavelength of the carbon dioxide laser marking machine is 10.64μm, and the laser wavelength of the ultraviolet laser marking machine is 355nm.

3.Different fields of application:

CO2 laser marking machine is suitable for engraving most non-metallic materials and some metal products. Fiber laser marking machine is suitable for engraving most metal materials and some non-metallic materials. UV laser marking machine can clearly mark all heat-sensitive materials. Adverse reactions to plastics and other materials.

Marking features and applications of CO2, optical fiber, and ultraviolet laser marking machines:

1. CO2 laser marking machine

Features:

a. High marking precision, fast speed, free control of engraving depth;

b. The laser has high power and can be used for engraving and cutting of various non-metallic products;

c. No consumables, low processing cost, and the operating life of the laser is as high as 20,000 to 30,000 hours;

d. Clear marking, not easy to wear, fast engraving and cutting efficiency, environmental protection and energy saving;

e. Use the 10.64nm laser beam to expand, focus, and finally control the deflection of the vibrating mirror;

f. Act on the working surface according to the predetermined trajectory, so that the working surface can be vaporized to achieve the marking effect;

g. Good beam mode, stable system performance, less maintenance, suitable for industrial processing sites with large batches, multiple varieties, high speed, and high-precision continuous production;

h. The most advanced optical path optimization design and unique graphic path optimization technology, coupled with the unique super pulse function of the laser, make the marking speed faster.

Applications:

Suitable for paper, leather, cloth, plexiglass, epoxy resin, wool products, plastics, ceramics, crystal, jade, bamboo and wood products. Widely used in various consumer goods, food packaging, beverage packaging, pharmaceutical packaging, architectural ceramics, clothing accessories, leather, textile cutting, craft gifts, rubber products, shell brands, denim, furniture and other industries.

2. Fiber laser marking machine

Features:

a. The marking software is very powerful, compatible with Coreldraw, AutoCAD, Photoshop and other application software; supports PLT, PCX, DXF, BMP, etc., and can use SHX, TTF fonts; supports automatic coding, printing serial number, batch number, date, barcode , QR code, automatic jump number, etc.;

b. Adopt an integrated structure, equipped with an automatic focusing system, and the operation process is humanized;

c. Use the original imported isolator to protect the fiber laser window, increase the enhanced stability and laser life;

d. No need for maintenance, long service life, small size, suitable for working in harsh environments;

e. The processing speed is fast, which is 2-3 times that of the traditional marking machine;

f. The electro-optical conversion rate is high, and the power consumption of the whole machine is less than 500W, which is 1/10 of the lamp-pumped solid-state laser marking machine, which greatly saves energy consumption;

g. The beam quality is much better than that of traditional solid-state laser marking machines. It is the fundamental mode, TEM00, and the diameter of the output focused spot is less than 20um. The divergence angle is 1/4 of that of the semiconductor pump laser.

Applications:

1. Stainless steel, anodizing, electroplating, phosphating products, common hardware, kitchen utensils, mobile phone casings, computer casings and other laser marking.

2. Serial numbers of electrical shells, electronic products and other products, LOGO PCB circuit boards, ABS shells, chip industry, plastic marks, ceramic products, etc.

3. Mobile phone battery labels, panels, mobile phone buttons, small daily necessities accessories, etc.

4. Laser marking of ceramics and EP materials: electronic component packaging, IC, etc.


3. UV laser marking machine


Features:

1. The whole machine has stable performance, small size and low power consumption.

2. High photoelectric conversion efficiency, water temperature cooling, stable laser output and long service life.

3. The laser spot output is extremely small and the light pattern is good, which is suitable for product marking with high requirements such as fine graphics and text.

4. The beam quality is good, the output laser is stable, and the marking effect is easy to debug.

5. The vibrating mirror adopts high-speed motor, which has fast response speed, high positioning accuracy and faster marking speed.

Applications:

1. Mainly used in the high-end market of ultra-fine processing, the surface marking of packaging bottles for medicines, cosmetics, food and other polymer materials, the effect is very fine and the marks are clear and firm, which is better than inkjet coding and pollution-free

2. Flexible PCB board marking, scribing, silicon wafer micro-hole, blind hole processing

3. LCD liquid crystal glass two-dimensional code marking, glassware surface drilling, metal surface coating marking, plastic buttons, electronic components, gifts, communication equipment, building materials, etc.
