Common Categories Of Laser Marking Machines

- Jul 11, 2018 -

In recent years, laser marking machine is becoming more and more widely used in industrial laser processing. Facing the demand of different product markings on the market, different types of laser marking machine have been produced. The mass group is called the laser marking machine, and the following classification is made for the common laser marking machine.

1.  fiber laser marking machine

It is the most widely used model at present. It uses optical fiber laser to output laser and then through ultra high speed scanning vibration mirror system to achieve marking function. The optical fiber laser marking machine has high electro-optical conversion efficiency, cooling by air cooling mode, a small volume of the whole machine, high output beam quality, high reliability, long-running life, and energy saving. It can engrave metal materials and some nonmetallic materials. It is mainly used in the fields of high demand for depth, smoothness and fine degree, such as mobile phone stainless steel piece, clock, mould, IC, mobile phone key and so on. The bitmap can mark the beautiful pictures on the surface of metal and plastic, and the speed of marking is the traditional first-generation lamp pump marking machine and the second generation of semiconductors. 3~12 times the standard machine.

2. CO2 laser marking machine

It uses CO2 metal (RF) laser, beam expanding focusing optical system and high-speed galvanometer scanner, with stable performance, long life and maintenance free. CO2 RF laser is a kind of gas laser. The wavelength of the laser is 10.64 mu m, which belongs to the middle infrared band. The CO2 laser has a relatively large power and a higher electro-optic conversion rate. Carbon dioxide laser uses CO2 gas as the working substance. It is mainly used in non-metal industries such as food, medicine, leather, tobacco, wood products, electronics, etc. The effect is better and more beautiful than screen printing and inkjet printing.

3. UV laser marking machine

UV laser marking machine is a cold light or UV laser marking, which is a more promising model. Many of the products of the optical fiber laser marking machine are not satisfied with the effect of the UV laser marking machine. Printed words, patterns, and so on, will be more fine, clear, mainly used in the enterprises on the text, patterns and other requirements of the main products on the market, the common use of ultraviolet laser 3W, 5W, 7W, 8W, 10W, 15W.
