laser marking on plastic

Plastic is an important product material. Marks used for identification, such as trademarks, bar codes and serial numbers, on plastic products are usually machined directly on the surface, such as stamping, engraving, punching and the like, or printed , Paste labels, shrinking shrink packaging and other external processing methods generated. The use of laser marking machine to print marks on the surface of plastic products is a high processing speed, plastic products can maintain the inherent surface characteristics, and print the mark with a lasting, counterfeit and high quality features, does not require other processing operations.


Some plastics are easy to mark because of their energy absorption, while others do not absorb the laser and can not be marked with a laser. The absorption rate of laser energy is a function of wavelength, so different plastics will get different quality marks under the same laser intensity. For example, some colored high-density polyethylene and polycarbonate with YAG laser, without adding any additives can get the ideal mark; and CO2 laser marking machine, without adding special additives will not be printed. In addition, the degradation of plastic, cracks, the surface of the hole, etc., will guide the quality of marked reduction.


Today, plastic products are widely used in a variety of industries, such as: appliances, cars, mobile phones, PCs, medical equipment, lighting appliances are an integral part of it!
