What is the marking principle of the fiber laser marking machine? The fiber laser marking machine manufacturers will give you a detailed introduction below.

The so-called fiber laser marking machine means that the marking machine uses a fiber laser, which has a small size (no water cooling device, air cooling) and good beam quality ( Basic model), maintenance-free and other features.

The current optical fiber equipment can not only reduce maintenance costs, but also have a greatly extended service life, and the marking effect is more precise and clear than the original.

The application field of fiber laser marking machine is very wide, which can be applied to integrated circuit chips, computer accessories, industrial bearings, clocks, electronic and communication products, aerospace devices, various auto parts, home appliances, hardware tools, molds , Wire and cable, food packaging, jewelry, tobacco and military affairs and many other fields such as graphics and text marks.

Fiber laser equipment uses high-energy-density laser beams to act on the surface of the processed product. Under the action of high-intensity energy, the product marking quickly vaporizes or chemically reacts, leaving traces on the product surface.

The contact surface is not only smooth and natural, but also does not damage the material near the marking surface.

Laser processing is different from traditional processing methods. Laser processing needs to process the surface of the material, and it must be able to absorb the laser of this wavelength in order to be processed. However, traditional processing does not have this requirement.

However, laser processing does not require consumables, and it will not cause product deformation disturbance. The computer is used to control and operate flexibly during processing.

It is these excellent performances that make the current fiber laser equipment more and more widely used. In some fields, traditional processing methods have been adopted, and the technology of continuous improvement and upgrading is constantly hitting the market occupied by traditional industries. .

In terms of price, the price of fiber laser marking machine is much more expensive than traditional equipment, but its excellent performance and lower maintenance cost have won the favor of many industries.

Especially for high hardness, high melting point, brittle materials, marking is more advantageous.

Select the laser equipment according to the needs of the product to be processed.

Laser equipment can be roughly divided into engraving, cutting and marking in different ways of use. Basically, some are dedicated machines, and some have multiple functions, which should be selected according to the main needs.

Which materials should be considered for marking.

According to the different laser production, laser marking machine has many types such as optical fiber, YAG and CO2.

For metal products or non-metal products, users should choose the appropriate type of marking machine.

Fiber laser marking machine is suitable for integrated circuit chips, computer accessories, industrial bearings, clocks and watches, electronic and communication products, aerospace devices, various auto parts, home appliances, hardware tools and other industries.

The carbon dioxide laser marking machine is suitable for marking most non-metallic materials, such as paper packaging, plastic products, label paper, leather cloth, glass ceramics, resin plastic, bamboo and wood products, PCB boards, etc.

The green laser marking machine is suitable for the surface and internal engraving of glass and crystal products, such as mobile phone screens, LCD screens, optical devices, automotive glass, etc.

Choose the appropriate machine format according to the size of the product to be processed.

For the choice of laser marking format, the larger the machine format, the better.

On the one hand, large-format equipment is of course more expensive, on the other hand, some poor-quality machinery and equipment have unstable average laser output at various points on the large-format, resulting in different levels of marking products on the same table. , So choosing the appropriate format is correct.
