Whether it is laser marking machine hot processing technology or cold processing technology, it is used to process the material surface layer

Laser marking machine thermal processing technology: using a high energy density and concentrated laser beam to irradiate the surface of the material being processed (metal, plastic, marking, etc.), the surface of the material absorbs laser energy and generates heat in the illuminated area The excitation process causes the temperature of the surface of the material (or coating) to rise, resulting in metamorphosis, melting, ablation, evaporation and other phenomena, and finally forms a preset labeling effect. Because it uses high temperature to achieve the desired effect, it is called thermal processing; for example: Fiber and semiconductor and co2 laser marking machines .

Laser marking machine cold processing technology: It is a high-tech equipment that has only appeared in recent years. It uses photons with high load energy (this photon is generally used as a light source of ultraviolet 355nm), which can modify the material or the surrounding medium. Until the material undergoes non-thermal process destruction. This kind of processing has special significance in laser marking processing, because it uses a low temperature, and the box bottom has a lower thermal ablation temperature, so it does not cause “heat damage” and achieve cold peeling. Therefore, it can damage the inner layer and nearby areas of the processed surface. Does not produce heating or thermal deformation; so this type of processing without high temperature evaporation is called cold processing, which is also the most advanced laser marking technology; such as: green light and ultraviolet laser marking machine . Both the laser marking machine's hot processing technology and cold processing technology are used to process the material surface layer. It can achieve permanent high-quality and fine marking effects for various substances and metals, and adopts a pressure-free processing method, not to mention It will cause damage to the processed products, so the advantages of advanced laser marking technology in the electronics, circuit board and other industries are preferentially adopted and replace the traditional marking equipment.
