The two principle of laser marking machine

by:J&D WATER     2020-03-22
Laser marking machine is beaten out with a laser beam in different kinds of material surface on forever. For a long time. Play the effect of mark is through material surface evaporation show deep material, or light, by the result of the surface material chemical physical change and & quot; Time & quot; The trace, either light burned by part of the material, show the etching pattern and text. Recognized as one of the two kinds of principle is: 1, the 'hot work' has a high energy density laser beam ( It is to focus on energy flow) Materials, processed materials on the surface, surface absorption of laser energy, produce thermal excitation in the area of the irradiation process, so that the material surface, Or coating) Temperature rise, produce abnormal, melting, ablation, the phenomenon such as evaporation. 2, 'cold' has the very high load energy ( Uv) Photon, can interrupt materials ( Especially the organic material) Or chemical bonds within the surrounding medium, damage to the thermal process in the material. The cold has special significance in the laser marking processing, because it is not a thermal ablation, but does not produce & quot; Thermal damage & quot; Side effects, cold strip break chemical bonds, and thus of the processed surface layer and the area does not produce heating or thermal deformation, and so on. Electric laser marking equipment recommended: preferential deals offer 4007001618 【 Optical fiber laser marking equipment 】 Mainly used for metal and non-metallic laser marking part USES, tags and beautiful, fast, no material; 【 CO2 laser marking equipment 】 Non-metallic products used for the laser marking purposes; 【 Uv laser marking equipment 】 Adopt import uv laser, it is mainly used for metal and non-metallic products fine marking purposes; 【 Metal laser marking equipment 】 Based on customer specific products, production line, the demand for design and production and customer demand, customized models. 【 Semiconductor laser marking machine 】 Stable performance, price moderate 【 Green laser marking machine 】 High prices, product customization is given priority to YAG laser marking machine 】 Metal, plastic and other products used for moderate price more electric laser marking equipment laser marking machines, laser marking
