Difference & Applications for Sunine four main laser marking machines!

Laser coding equipment, also known as laser inkjet printer, laser marking machine.

According to different laser sources, it can be divided as:

CO2 laser printer, Semi-conductor laser printer, YAG laser printer, Fiber laser marker.

According to the different laser visibility, it is divided   as:

UV laser coding machine (invisible laser), GL laser coding machine (visible laser), Infrared laser coding machine (invisible laser).

At present, the main laser coding machines can be divided into 4 series: UV, GL, Fiber,   CO2.

By wavelength: according to different laser sources, the wavelengths for laser marking machines are also deviated,   there are mainly   4 types of wavelengths: 266nm, 532nm, 1064nm and 10.64um.

Difference:

   Laser wavelength: UV laser coders (266nm), Fiber laser coders (1064nm), GL laser coders (532nm), CO2 laser coders (10.64um).

Working Principle:

CO2 laser coding machine:

It adopts CO2 gas be charged into the discharge tube as the medium for generating laser, a high voltage is applied to the electrode, a glow electronic is

generated in the discharge tube, which causes the gas molecules to release the laser, and the laser energy is amplified to form a pair of laser beams for material processing.

Fiber laser coding machine:

The laser is directly transmitted by the optical fiber, the beam quality is better, and the utilization of light energy is maximized.

GL coding machine:

It is developed by using the most advanced laser pumping technology (side pumping or end pumping) with a wavelength of 532nm in the world.

UV laser coding machine:

It adopts 355nm wavelength UV laser generator, using third-order cavity frequency doubling technology,its main features are short wavelength,

355 UV light focusing spot is extremely small, which can greatly reduce the material quality damage during processing, its "cold treatment" technology is suitable for materials that are greatly affected by heat, and can also achieve marking in the ultra-fine field.

Applicable Material :

CO2 laser coding machine:

bamboo and wood products, paper, cloth, leather, plexiglass, epoxy resin, acrylic, PE, PO, PP, OPP, PPE, EVA and other non-metallic materials.

Fiber laser coding machine:

Most metal materials and some plastic materials.

GL coding machine:

Plastic, silicon, gold & silver jewelry, glass, electronic products, hardware, ceramics, etc.

UV laser coding machine:

Carton packaging, cable casings, colored plastics, polymers, semiconductor materials, silicon wafers, LCD glass, metal, plastic buttons, electronic components, communication equipment, building materials, data cable, etc.

Summarize:

Fiber laser marking machine

It is mainly composed by 3 parts: laser source, galvanometer and marking card. It adopts the fiber laser source to produce laser . The beam quality is good,

its output center is 1064nm, and the life of the whole machine is about 100,000 hours. Compared with other types of laser coding machines, this machine has a longer life. And compared with other type laser coding machines with conversion efficiency of 2%-10%, this machine has a great advantage with the conversion efficiency as 28%, it has outstanding performance in energy saving and environmental protection.

CO2 laser marking machine

CO2 laser source is a gas laser source with a wavelength of 10.64um infrared light.   It adopts CO2 gas be charged into the discharge tube as the medium for generating laser. When a high voltage is applied to the electrode, a glow electronic is generated in the discharge tube, can causes gas molecules to release laser. The laser energy is amplified to form a laser beam for material processing.

UV laser coding machine

UV laser marking machine is equipped with deep UV laser source, imported high-speed galvanometer scanner system, etc.;   because its focusing spot is extremely   small, and the processing heat affected zone is very small, so UV laser marking machine can perform ultra-fine marking, special Material marking, it is the first

choice for customers who have higher requirements on marking effect.   It has the characteristics of high electro-optical conversion rate,long life of nonlinear crystal,stable operation, high positioning accuracy, high operation efficiency,modular design for easy installation and maintenance.

In addition, a two-dimensional automatic workbench can be selected to realize multi-station continuous marking or large-format marking.

GL laser coding machine

The GL marking machine is developed by using the most advanced laser pumping technology (side pumping or end pumping) with a wavelength of 532nm in the

world. Customers can freely choose the pump type according to the characteristics of their own products. The electro-optical conversion rate is high, up to 30% or 45%, and the power consumption is low, the protection is very good. It can be widely used: marking on various metals (such as stainless steel, copper alloys, etc. ) and various non-metallic materials (such as glass, gemstones,ceramics, electroplated buttons, gold-plated devices, etc.), optical devices (such as optical Lenses,

etc.) engraving or scale marking, and also suitable for ceramic drilling, direct molding of high-temperature PCB boards, etc.

Compared with similar products, it has quite high performance, more suitable for some objects requiring finer and higher precision.
