What are the application characteristics of laser marking on plastic materials?

Plastic laser markingIt is widely used. According to the material, several models can be selected for configuration to produce different effects. It can be applied to high information density such as numbers, text, trademarks or machine-readable codes to arrange data matrix codes in dense spaces of different scales. So, what are the application characteristics of laser marking on plastic materials?

Accuracy: Like metal scratching, it has good focusing performance and is therefore very suitable for fine marking. The laser device of the utility model has high beam quality and can obtain a smaller focusing diameter during the calibration process. In this way, track widths as small as nanometers can be accurately achieved.

Wave absorption characteristics: The laser used for marking generally generates radiation in the infrared band. Lasers and ultraviolet lasers are used to manufacture plastic and semiconductor materials. As a special sign application for laser engraving machines, the use of UV wavelengths provides new possibilities for laser marking on plastics. Short wavelengths react photochemically with plastic composites, are not heated, and do not damage materials; they play an irreplaceable role in the plastics industry!

But in the application of plastic marking, the potential of lasers is far from enough. In addition to the above advantages, marking machines that surpass lasers have also opened up more new areas for the application of lasers in the plastics industry. In addition to no loss and no pollution, laser marking has the characteristics of fast speed, good labeling effect and anti-counterfeiting, which is very popular among enterprises.
