Principle and material advantages of laser marking machine
1、 Fiber laser marking machine
Fiber laser is mainly based on the principle of laser thermal effect, which uses the high heat generated by the laser to burn the surface of the workpiece to form the product mark. It is mainly used for metal material and some plastic material marks. At present, the fiber laser marking machine is the most mature, the longest life, the most widely used and the most affordable model on the market, which is widely used in the packaging industry.
2、 CO 2 laser marking machine
CO2 laser is mainly used to vaporize the coating on the surface of the workpiece to form a contrast mark through the thermal effect of the laser. CO2 laser is suitable for all kinds of non-metallic and some metal materials, such as paper, PVC, rubber, wood, glass, ceramics, plastics, pet, HDPE, leather, etc. Widely used in packaging boxes, bags, films, glass bottles, pipes, electronic components and other industrial batch online inkjet!
3、 Infrared laser marking machine
It has the characteristics of high peak value, narrow pulse width and long focal depth; It is widely used in car keys, keyboards, high-quality metal two-dimensional codes and fine text Icon engraving.
4、 Green laser marking machine
Green laser is a kind of light source between hot light source and cold light source. The wavelength of green light is 532nm. It has the characteristics of thin spot and good beam quality. The equipment can be used for most metal and nonmetal surface processing and coating film processing. It is suitable for surface and interior carving of glass and crystal products, wine bottle carving, automobile glass, etc. It is especially suitable for marking, engraving and other surface treatment of high flame retardant materials.
5、 Ultraviolet laser marking machine
UV laser marking machine is mainly used for the surface and internal carving of glass and crystal products, such as mobile phone screen, LCD screen, optical devices, automobile glass, etc. At the same time, it can be applied to the surface processing and coating film processing of most metal and non-metal materials. Such as hardware, ceramics, glasses, clocks, PC, electronic devices, all kinds of instruments, PCB board and control panel, nameplate display board, plastic, etc., suitable for marking, engraving and other surface treatment of high flame retardant materials. Metal and a variety of non-metallic materials, ceramics, sapphire chip, glass, transparent polymer materials, plastics.
There are many brands of laser marking machines, but there are not many domestic companies that can produce and repair them. If they buy a company that can't repair them, they will have to find someone to repair them. Once they come back for half a month, customers can't afford the loss, and it's a waste of money to repair them
