Laser Marking Machine Features

There are two generally recognized principles:
"Hot processing" uses a laser beam with a high energy density (it is a concentrated energy flow) to irradiate the surface of the processed material. The surface of the material absorbs the laser energy and produces a thermal excitation process in the irradiated area, thereby causing the temperature of the material surface (or coating) to rise, resulting in metamorphosis, melting, ablation, evaporation and other phenomena.
"Cold processing" uses (ultraviolet) photons with very high load energy, which can break the chemical bonds in the material (especially organic materials) or the surrounding medium, causing the material to be destroyed by non-thermal processes. This cold processing has special significance in laser marking processing, because it is not thermal ablation, but cold peeling that breaks the chemical bonds without the side effect of "thermal damage", so it does not cause heating or thermal deformation to the inner layer and nearby areas of the processed surface. For example, in the electronics industry, excimer lasers are used to deposit chemical films on the base material and to open narrow grooves on the semiconductor substrate.
Comparison of different marking methods
Compared with inkjet marking, the advantages of laser marking engraving are: a wide range of applications, and a variety of materials (metals, glass, ceramics, plastics, leather, etc.) can be marked with permanent high-quality marks. There is no force on the surface of the workpiece, no mechanical deformation, and no corrosion on the surface of the material.
Product Application
It can engrave a variety of non-metallic materials. It is 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.
1. It can engrave metals and a variety of non-metallic materials. It is more suitable for processing some products that require fineness and high precision.
2. It is used 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 industries.
3. 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 (all kinds of metal oxides), special surface treatment (phosphating, aluminum anodizing, electroplating surface), ABS material (electrical appliance housing, daily necessities), ink (translucent buttons, printed products), epoxy resin (encapsulation of electronic components, insulation layer).
