Classification of Laser marking machines
1、 According to the principle and characteristics:
- According to the laser wavelength: 532nm Laser marking machine, 808nm Laser marking machine, 1064nm Laser marking machine, 10.64um Laser marking machine, 266nm Laser marking machine. One of the most widely used is 1064nm. Can also be roughly said to be ultraviolet Laser marking machine, green Laser marking machine, infrared Laser marking machine.
- According to the laser: CO2 Laser marking machine, semiconductor Laser marking machine, YAG Laser marking machine, fiber Laser marking machine.
2、 By industry specific:
- Fiber Laser marking machine
This is the most widely used model at present. It uses fiber laser to output laser, and then uses ultra-high speed scanning galvanometer system to realize the marking function. The fiber Laser marking machine has high electro-optic conversion efficiency, adopts air cooling mode to cool, the whole machine has small volume, good output beam quality, high reliability, ultra long operation life and energy saving, It can carve metal materials and some non-metal materials. It is mainly used in the fields with high requirements for depth, smoothness and fineness, such as mobile phone stainless steel ornaments, clocks, molds, IC, mobile phone keys and other industries. Bitmap marking can mark beautiful pictures on metal, plastic and other surfaces, and the marking speed is 3-12 times of the traditional first generation lamp pumped marking machine and the second generation semiconductor marking machine.
- Ultraviolet Laser marking machine
UV Laser marking machine is a kind of cold light or UV Laser marking machine, which is a more promising model. Many products can not be marked by fiber Laser marking machine. Generally, UV Laser marking machine can mark. The printed words and patterns will be more precise and clear. They are mainly used in the main products with higher requirements for words and patterns. The commonly used ultraviolet lasers on the market are 3W, 5W, 7W, 8W, 10W and 15W.
It adopts CO2 metal 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 laser wavelength is 10.64 μ m. CO2 laser belongs to mid infrared band, which has high power and high electro-optic conversion rate. CO2 laser uses CO2 gas as working material.
