Plastic laser marking machines generally refer to carbon dioxide laser marking machines. General laser marking machines are widely used for marking metals and non-metals. Laser marking machines can be applied to digital, text, trademark or machine-readable codes. For example, they have high information density and are arranged in different sizes in tight spaces. Data matrix code. But you do not necessarily know the two characteristics of marking on plastic!

Precision Marking: Lasers are diode-pumped lasers with high energy efficiency. Like the metal marking machine, it also has a good focusing ability, so it is very suitable for fine marking. Diode-pumped solid-state lasers have a very high beam quality, resulting in a very small focusing diameter for the laser beam during the marking process. In this way, it is possible to achieve a fine marking track width as small as micrometers on minute components.

Adaptation of absorption characteristics: Lasers used for marking usually produce radiation in the infrared wavelength range. Green lasers and UV lasers are aimed at plastic and semiconductor materials. In the special marking applications of laser engraving machines, the use of UV wavelengths has opened up new possibilities for laser marking on plastics. The short wavelength directly produces a photochemical reaction with the plastic compound without heating, so as not to damage the material; the laser marking machine in the plastic industry has now reached an irreplaceable role!

For now, in the application of plastic marking, the potential of laser is far from being exerted. Laser cutting machines have had some applications on this machine, but due to lack of enhanced development, they have caused premature death. In addition to the above-mentioned advantages, the frequency multiplier laser and frequency tripled laser have been increasingly popularized, as well as materials and processes. The diversity of the combination is opening up more new fields for laser applications in the plastics industry. The marking of plastics by laser marking machines, in addition to free consumables and non-pollution, also has the characteristics of high speed, good marking effect, and strong anti-counterfeiting property, and is widely welcomed by enterprises.
