Plastic material laser marking machine generally refers to the carbon dioxide laser marking machine. Laser marking machines can be applied to numbers, texts, trademarks, etc., such as data matrix codes with high information density and arranged in tight spaces at different scales. However, there are two characteristics of the plastic marking. Today, Zeze Xiaobian, a detailed introduction:
1. Precision marking: The laser is a diode-pumped laser with high energy efficiency. Like the metal marking machine, it also has an excellent focusing ability, 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 micrometers 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 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 composite without heating, so that the material is not damaged; in the plastics industry, the laser marking machine has now reached an irreplaceable role.
In plastic marking applications, the potential of lasers is far from being realized. In the marking of plastics, the laser marking machine has the characteristics of fast speed, good marking effect, and strong anti-counterfeiting, in addition to no consumables and no pollution.
