Plastic laser marking machine generally refers to ultraviolet laser marking machine. Generally, laser marking machines are widely used in metal and non-metal marking. Laser marking machines can be applied to numbers, texts, trademarks or machine-readable codes, such as data matrix codes with high information density and arranged in close space on different scales. 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. Like metal marking machine, it also has good focusing ability, so it is very suitable for fine marking. Diode pumped solid-state laser has high beam quality, which makes the laser beam obtain a small focusing diameter in the marking process. In this way, the precision marking track width as small as microns can be realized on small parts.
Adaptation of absorption characteristics: lasers used for plastic marking usually produce radiation in the infrared wavelength range. Green laser and ultraviolet laser are aimed at plastics and semiconductor materials. In the special marking application of laser engraving machine, the use of UV wavelength creates a new possibility of laser marking on plastics. Short wavelength directly produces photochemical reaction with plastic composites without heating, so as not to damage the materials; In the plastic industry, laser marking machine has now played an irreplaceable role.
At present, in the application of plastic marking, the potential of laser is far from being brought into play. In addition to free consumables and no pollution, laser marking machine also has the characteristics of fast speed, good marking effect and strong anti-counterfeiting.
