Metal Laser Marking Machine Fiber Laser Engraving

Metal laser marking machine  is emerging high-tech machinery and equipment in recent years. Fiber laser engraving has a wide range of applications, such as hardware products, precision equipment, electrical appliances, and many of the words on PVC pipes are marked with fiber marking machines. The laser fiber marking machine came out in just a few years and replaced most of the marking products on the market.

Fiber Laser Marking Machine's working principle is that to make use of fiber laser to generate laser and export the laser with optical fiber and then cooperate with optical high-speed scanning galvanometer for workpiece marking, the core of which is fiber laser source. The term “LASER” is an abbreviation of Light Amplification by Stimulated Emission of Radiation, a light wave of single wavelength that has not been adulterated. The Laser Marker Machine comprises of an oscillator that is responsible for amplifying laser light as it reciprocates between the reflecting mirrors. Normally, the materials that are considered compatible with the fiber laser marking machine are metals, coated metals, glass, plastics, stone, etc. Additionally, it is also used in the cylinder and flexographic plates marking. The Co2 laser is mostly preferred with the machine to perform these applications that produces the print ready surface by evaporating the sleeve material and rubber plates.

Fiber lasers use rare earth doped fibers as the gain medium. Due to the fine fiber core in the fiber laser, it is easy to form a high power density in the fiber under the action of the pump light, resulting in a laser energy level "inversion of the number of particles" of the laser working substance. Therefore, the laser oscillation can be formed when the positive feedback loop is properly formed to form the resonant cavity. In addition, because the fiber matrix has a wide spectrum of fluorescence, fiber lasers are generally made to be tunable (ie. their wavelength can be adjusted within a certain range). Some core features are as below:

Why the metal laser marking machine  is so popular?

metal laser marking machine  is suitable for lots of materials, including hard plastics, silver, gold, copper and other metal materials, silicon chips, etc. Fiber laser machines are simple and easy to use, it has the following features:

Long time:

After the logo is not easy to disappear, it is almost forever, due to the natural environment (touch, acid and alkaline gas, high temperature)

Anti-counterfeiting identification:

It is not easy to copy and change, and has strong anti-counterfeiting identification

Non-contact:

The fiber laser marking machine is working with a non-mechanical “light knife”, it can print logos on all standard or curved surfaces

The steel parts do not become hot after laser engraving, ensuring the original of the steel parts precision.

It does no erosion on the working surface, there is no “CNC blade” damage, health promotion, and environmental friendliness. This is a clean and friendly high environmental protection production and processing technology.

Widely used:

Using a fiber laser can produce and process a variety of metal materials and non-metal materials.

Advantages of metal laser marking machine :

.Permanent effect The marks made by a fiber laser marker will not fade due to any changes in time, environment and other elements. And the marking effect is difficult to imitate and change, and has a strong anti-counterfeiting function. Therefore, the fiber laser marker machine has prominent advantages in the automotive and other industries where traceability requirements are very strict.

Delicate marking effect The minimum spot diameter of the fiber laser marking machine after focusing can reach 0.04mm or less, so the marking effect is quite delicate.

Low operation cost Although the purchase investment is larger than that of a traditional marking equipment, the metal laser marker has faster marking speed and smaller energy consumption. And the fiber laser engraving machine is easy to operate and does not require many consumables. As long as the laser can work normally, the laser marker machine can achieve long-term continuous marking. Comprehensively, it has great advantages compared with traditional marking methods in terms of use cost and overall technical benefits.

Non-contact processing The energy carrier of fiber laser marking is a beam of uniform wavelength. The beam does not produce any mechanical stress when irradiating the surface of the material. Therefore, it will not affect the mechanical properties of the material, and also eliminate the chemical and noise pollution. The marks are clean and tidy.

Strong adaptability Fiber laser cutting machine can mark most metals and some non-metal materials. Because of the use of computer intelligent control, the fiber laser engraving machine can quickly adjust the marking content through software, including bar codes, QR codes, etc. It is also compatible with multiple file formats, like DXF, BMP, JPG, CAD, CDR, DWG, etc. This provides great convenience for flexible processing.

Environmentally friendly Fiber laser marking has no pollution source and is a clean and environmentally friendly processing method.
