Product features of laser marking machine
There are two generally accepted principles:
'thermal processing' laser beams with higher energy density ( It is a concentrated energy flow) that shines on the surface of the material being processed, the surface of the material absorbs laser energy, and a thermal excitation process occurs in the irradiated area, so that the temperature of the surface (or coating) of the material rises, resulting in abnormality, melting, burning Erosion, transpiration, etc.
'Cold working' (ultraviolet) photons with very high loading energy can break the chemical bonds in the material (especially organic materials) or the surrounding medium, so that the material is damaged by non-thermal processes. This cold working has special significance in laser symbol processing, because it is not thermal ablation, but cold peeling that does not produce the side effect of 'thermal damage' and breaks chemical bonds, so the inner layer and nearby areas of the processed surface are affected. Does not produce effects such as heating or thermal deformation. For example, excimer lasers are used in the electronics industry to deposit thin films of chemical substances on substrate materials and to create narrow grooves in semiconductor substrates.
Comparison of different symbol methods
Compared with inkjet marking method, the advantages of laser marking and engraving lie in: a wide range of applications, a variety of substances (metal, glass, ceramics, plastics, leather, etc.) can be permanently marked with high quality. It has no effect on the surface of the workpiece, does not produce mechanical deformation, and does not corrode the surface of the material.
It can carve a variety of non-metallic materials. Used in clothing accessories, pharmaceutical packaging, wine packaging, architectural ceramics, beverage packaging, fabric cutting, rubber products, shell nameplates, craft gifts, electronic components, leather and other industries.
●It can carve metal and various non-metal materials. It is more suitable for the processing of some products that require fine and high precision.
Applied in electronic components, integrated circuits (IC), electrical appliances, mobile communications, hardware products, tool accessories, precision instruments, glasses and clocks, jewelry, auto parts, plastic buttons, building materials, PVC Pipes, medical equipment and other occupations.
●Applicable materials include: common metals and alloys (iron, copper, aluminum, magnesium, zinc and other metals), rare metals and alloys (gold, silver, titanium), metal oxides (all kinds of metals) oxide), special surface treatment (phosphating, aluminum anodizing, electroplating surface), ABS material (electrical appliance shell, daily necessities), ink (translucent keys, printed products), epoxy resin (electronic components packaging, Insulation).
Nowadays, the adoption of cij printer in expiry date printing machine industry is quite common.
