"Hot processing"-a laser beam with a higher energy density (which is a concentrated energy flow) is irradiated on the surface of the material being processed. The surface of the material absorbs the laser energy and generates a thermal excitation process in the illuminated area, so that the surface of the material (Or coating) The temperature rises, causing metamorphosis, melting, ablation, evaporation and other phenomena.


"Cold work"-(ultraviolet) photons with very high load energy, which can break the chemical bonds in materials (especially organic materials) or the surrounding medium, causing the materials to undergo non-thermal process destruction. This kind of cold processing is of special significance in laser marking processing, because it is not thermal ablation, but cold peeling that breaks the chemical bond without the side effect of "heat damage", so it does not affect the inner layer and nearby areas of the processed surface. Generates heating or thermal deformation. For example, in the electronics industry, excimer lasers are used to deposit a thin film of a chemical substance on a substrate material to create narrow grooves in a semiconductor substrate.
        
Laser marking features: a wide range of applications, a variety of substances (metals, glass, ceramics, plastics, leather, etc.) can be marked with permanent high-quality marks. No force on the surface of the workpiece, no mechanical deformation, no corrosion on the surface of the material. Can be used for marking of integrated circuits, resistors, capacitors, crystals, diodes, transistors and other devices. Laser marking machine is mainly used in craft gifts, furniture, leather clothing, advertising signs, model making, food packaging, electronic components, pharmaceutical packaging, printing and plate making, casing nameplates, etc.
