Plastic laser marking machine generally refers to ultraviolet laser marking machine. Generally, laser marking machines can mark on metals and non-metals. The laser marking machine can be applied to numbers, text, trademarks or machine-readable codes, such as those with high information density and arranged in tight spaces on different scales. Data matrix code. Next, let me know about the characteristics of plastic laser marking machine on plastic marking.
Precision marking: The laser of the plastic laser marking machine is a diode pumped laser with high energy efficiency. It also has good focusing ability like metal marking machine, so it is very suitable for fine marking. The diode-pumped solid-state laser has a high beam quality, so that the laser beam in the marking process can obtain a small focus diameter. In this way, precise marking track widths as small as micrometers can be realized on tiny parts.
Adaptation of absorption characteristics: Lasers used for plastic marking usually produce radiation in the infrared wavelength range. Green lasers and ultraviolet lasers target plastic and semiconductor materials. In the special marking applications of laser engraving machines, 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 compound without heating, thereby not causing damage to the material; in the plastics industry, laser marking machines have now reached an irreplaceable role!
At present, in the application of plastic marking, the potential of laser is far from being used. Laser marking machine in plastic marking, in addition to free of consumables and pollution-free, it also has high speed, good marking effect and anti-counterfeiting. Strong characteristics.
