Plastic laser marking machine generally refers to UV laser marking machine. General laser marking machine in metal and non-metal marking are very extensive, laser marking machine can be applied to numbers, text, trademarks or machine-readable code, such as high information density, in different scales arranged in a tight space of the data matrix code. 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. And metal marking machine also has a good focusing ability, so it is very suitable for fine marking. Diode-pumped solid-state laser has high beam quality, so that the laser beam in the marking process can obtain a small focusing diameter. In this way, precise marking track widths as small as microns can be achieved on tiny components.
Adaptation of absorption characteristics: Lasers used for plastic marking usually produce radiation in the infrared wavelength range. Green lasers and ultraviolet lasers target plastics and semiconductor materials. In the special marking application of laser engraving machine, the use of UV wavelength opens up new possibilities for laser marking on plastic. The short wavelength directly produces photochemical reaction with the plastic complex without heating, so as not to damage the material; Laser marking machine in the plastics industry has now reached an irreplaceable role!
For now, in the application of plastic marking, the potential of laser is far from being played out in the marking of plastic laser marking machine, in addition to consumables free, no pollution, but also has the characteristics of fast speed, good marking effect, and strong anti-counterfeiting.
