CO2 laser marking machine is a laser beam on the surface of a variety of substances marked with a permanent mark. Marking the effect of evaporation through the surface material exposed deep material, or through the light caused by chemical and physical changes in surface material "carved out" traces, or by burning some of the light energy, showing the required etching Patterns, text.

CO2 laser marking machine is a laser beam on the surface of a variety of substances marked with a permanent mark. Marking effect is through the surface layer of material evaporation to reveal deep material, which engraved fine patterns, trademarks, dates, LOGO or text, the current CO2 laser marking machine is mainly used in some of the more demanding, more accurate occasions. Used in food, medicine, wine, electronic components, integrated circuits (IC), electrical appliances, mobile communications, building materials, PVC pipe, acrylic, wood bamboo, and other industries, CO2 laser marking machine and Pen Maji than the main advantage is No consumables and permanent environmental aspects.

There are two accepted principles: "Hot working" A laser beam (which is a concentrated energy flow) with a higher energy density, which is irradiated on the surface of the material being processed, absorbs laser energy on the surface of the material and generates a thermal excitation process in the irradiation area , So that the material surface (or coating) temperature rise, resulting in metamorphosis, melting, ablation, evaporation and so on. "Cold working" (UV) photons with very high load energy, capable of interrupting chemical bonds in materials (especially organic materials) or surrounding media, causing non- thermal process failure. This cold working has special significance in laser marking processing because it is not thermal ablation, but does not produce "thermal damage" side effects, interferes with cold stripping of the chemical bonds, and thus does not work on the inner surface of the processed surface and in the vicinity thereof Produce heat or heat deformation and so on. For example, in the electronics industry, an excimer laser is used to deposit a thin film of a chemical on a substrate material, and a narrow groove is formed on the semiconductor substrate. Applicable materials and industry applications CO2 laser marking machine can engrave a variety of non-metallic materials. Used in garment accessories, medical packaging, building ceramics, beverage packaging, fabric cutting, rubber products, shell nameplate, craft gifts, electronic components, leather and other industries. Typical applications, such as packaging box laser flying marking, paper, metal detonator shell coding printing.
