There are two recognized principles of laser marking on laser marking machines:

Laser marking machine ( laser marking machine ) is used to mark the surface of various materials with a laser beam. The effect of marking is to expose the deep substance through the evaporation of the surface substance, so that exquisite patterns, trademarks and characters are engraved. Laser marking machines are mainly divided into: CO2 laser marking machines , semiconductor laser marking machines , fiber laser marking machines And YAG laser marking machine . At present, the laser marking machine is mainly used in some occasions that require more fine and higher precision. Used in electronic components, integrated circuits (ICs), electrical appliances, mobile phone communications, hardware products, tool accessories, precision equipment, glasses and watches, jewelry, auto parts, plastic keys, building materials, PVC pipes.

Laser marking is the use of laser beams to apply permanent marks on the surface of various substances. The effect of marking is to expose deep substances through evaporation of surface substances, or to cause chemical and physical changes in surface substances through light energy. "Carved" Traces are created, or part of the material is burned by light energy, showing the pattern and text to be etched.


There are two accepted principles:

"Hot processing" has a high energy density laser beam (it is a concentrated energy flow). The laser marking machine irradiates the surface of the material being processed. The surface of the material absorbs the laser energy, which generates a thermal excitation process in the illuminated area, so that The temperature of the material surface (or coating) rises, resulting in metamorphosis, melting, ablation, evaporation and other phenomena.

"Cold-processed" (ultraviolet) photons with very high load energy can destroy chemical bonds in materials (especially organic materials) or the surrounding medium, resulting in non-heat-treated damage. This cold processing is of special significance in the processing of laser marking machines , because it is not thermal ablation, but does not cause "thermal damage". As a side effect, cold peeling breaks the chemical bonds, thus the inner layer and the vicinity of the processed surface. This area does not generate heat or thermal deformation. For example, in the electronics industry, excimer lasers are used to deposit thin films of chemicals on substrate materials to form narrow trenches in semiconductor substrates. Application range can engraving various non-metal materials.

Laser marking machine is used in clothing accessories, pharmaceutical packaging, alcohol packaging, building ceramics, beverage packaging, fabric cutting, rubber products, shell nameplates, craft gifts, electronic components, leather and other industries. ● Engraves metal and various non-metal materials. It is more suitable for processing products that require precision and precision. ● Used in electronic components, integrated circuits (ICs), electrical appliances, mobile communications, hardware, tool accessories, precision instruments, glasses and watches, jewelry, auto parts, plastic buttons, building materials, PVC pipes, medical equipment and other industries.

● Applicable materials include: common metals and alloys (all metals, such as iron, copper, aluminum, magnesium, zinc, etc.), rare metals and alloys (gold, silver, titanium), metal oxides (various metals) oxides can) , Special surface treatment (phosphating, aluminum anodizing, electroplated surface), ABS material (appliances of electrical appliances, daily necessities), laser marking machine ink (transparent buttons, printing products), epoxy resin (electronic component packaging, insulation)).
