CO2 laser marking several features on the plastic

General laser marking on metal and nonmetal marking is very broad, laser marking machine can be applied to numbers, text, trademarks, or machine-readable code, such as having a high information density, different size arranged in a tight space data matrix codes. But in the plastic marking generally refers to CO2 laser marking machine, and which has the following two characteristics:
1. Precision Marking: laser source is a diode-pumped laser with high energy efficiency. Similar with metal marking machine, the CO2 laser also has a good ability to focus, making it ideal for fine marking. Diode-pumped solid laser has high quality beam, so that the process of marking the laser beam to obtain a small focus diameter. This can be achieved in small parts small precision marking microns width.
2. The absorption characteristics of adaptation: for marking lasers typically produce radiation in the infrared wavelength range. Green lasers and ultraviolet lasers are for plastics and semiconductor materials. In the laser engraving machine special marking applications, the use of UV wavelengths, creating a laser marking on plastic new possibilities. Short wavelength directly and plastic composites photochemical reactions, without heating, thereby not generating material damage; in the plastic industry CO2 laser marking machine has come to an irreplaceable role!
