Plastic laser marking machine generally refers to the carbon dioxide laser marking machine. General laser marking machines are very widely used for marking on metal and non-metal. Laser marking machines can be applied to digital, text, trademark or machine-readable codes, such as high information density and arranged in close spaces in different sizes. Data matrix code. But you don't necessarily know the characteristics of marking on plastic: let Leize Laser tell you the following: 2 characteristics of laser marking machine on plastic marking:
1. precision marking: the laser is a diode-pumped laser, with high energy efficiency. It has the same excellent focusing ability as the metal marking machine, so it is very suitable for fine marking. Diode-pumped solid-state lasers have high beam quality, resulting in a small focus diameter for the laser beam during marking. In this way, it is possible to achieve a precision marking track width as small as micrometres on minute parts.
2. Adaptation of absorption characteristics: Lasers used for marking usually produce radiation in the infrared wavelength range. Green lasers and UV lasers target plastic and semiconductor materials. In the special marking application of laser engraving machine, the use of UV wavelengths opens up new possibilities for laser marking on plastics. The short wavelength directly produces a photochemical reaction with the plastic composite without heating, so that the material is not damaged; in the plastic industry, the laser marking machine has now reached an irreplaceable role!
For now, in the application of plastic marking, the potential of the laser is far from being realized. The laser cutting machine used to have some applications on this, but it has not been strengthened, resulting in the collapse. In addition to the above-mentioned benefits, the proliferation of frequency-doubled lasers and triple-frequency lasers, as well as materials and processes The diversity of combinations is opening up new areas for the application of lasers in the plastics industry. In addition to free of consumables and pollution, the laser marking machine has the characteristics of fast speed, good marking effect and strong anti-counterfeiting. It is widely welcomed by enterprises.
