With the increasing application of laser marking, it is not only used for metal laser marking, but also for mass printing on plastic parts. For example, in previous barcode applications, laser marking of 2D barcodes was more accurate and precise. The marking of plastic parts generally uses CO2 laser coding machine.
Application of carbon dioxide laser marking equipment on plastic parts:
How to choose the best marking technology for widespread use depends on the particular application of the marking, the type of plastic and the wavelength of the laser light source. The color change method is suitable for most thermoplastics. Carbonization is used to create dark markings on bright backgrounds, and in most cases a 532 or 355 nm laser is used.
Using the foaming law to produce bright markings on a dark background (usually black), a laser with a wavelength of 1064 nm is used. For thermoset and elastic plastics, engraving is more suitable (the wavelength of the laser is 1064 nm in most cases).

Things have changed as laser processing technology has replaced inkjet printing in some applications. For current so-called "non-aesthetic" applications, an estimated 90% of plastic laser marking is produced by marking the CO2 laser printers, including part model, date of manufacture and expiration date.
Laser marking has been successfully used in commercial fields, including graphic marking and cutting in clothing accessories, leather, food and beverage packaging, electronic components, handicrafts, glass, stone processing and other fields.
For the marking of various non-metallic materials, such as paper packaging, plastic products, labels, paper, leather, cloth, glass, ceramics, plastics, wood products and PCB boards, the labels are usually printed with black letters and numbers, or printed sterling silver labels on a black background.
