Product characteristics of laser marking machine

Release date:2015-09-19Views:1555

Two kinds of theories are generally accepted:

"Hot working" with a high energy density of laser beam (which is the concentrated energy flow), irradiation on the surface of the material, the material surface to absorb the laser energy, in the irradiated area to produce thermal excitation process, so that the material surface (or coating) temperature rise, resulting in a change, melting, ablation, evaporation and other phenomena.

"Cold working" has a high load of energy (ultraviolet) photons, can interrupt the material (especially organic materials) or the chemical bonds in the surrounding medium, to make the material non thermal process damage. This kind of cold processing has special significance in laser marking processing, because it is not the heat, but does not produce the "heat damage" side effect, the interruption of the chemical bonds of the cold strip, so that the surface of the inner layer and the nearby area does not produce heating or heat distortion and so on. For example, the use of excimer laser in the electronic industry to deposit chemical material on the substrate material, the semiconductor substrate on a narrow groove.

Comparison of different labeling methods

Compared with the ink jet marking method, the advantages of laser marking are: wide application, many kinds of materials (metal, glass, ceramic, plastic, leather, etc.) can be permanently high quality mark. No force on the surface of the workpiece, does not produce mechanical deformation, the surface of the material does not produce corrosion.

Product application

Can carve a variety of non-metallic materials. For garment accessories, pharmaceutical packaging, liquor packaging, building ceramics, beverage packaging, fabric cutting, rubber products, shell plates, craft gifts, electronic components, such as leather industries.

Can be carved metal and a variety of non-metallic materials. More suitable for use in some of the requirements of precision, high precision products processing.

Application in electronic components, integrated circuits (IC), electrical appliances, mobile communications, hardware, tools, accessories, precision instruments, watch glasses, jewelry, auto parts, plastic buttons, building materials, PVC pipe, medical equipment and other industries.

] applicable materials include: ordinary metals and alloys (iron, copper, aluminum, magnesium, zinc and so on all metals, rare metals and alloys (gold, silver, titanium) and metal oxide (various kinds of metal oxides can be), special surface treatment (phosphate, aluminum anodizing, plating surface), ABS material (shell of electrical appliances, daily necessities), ink (transparent keys, printing products), epoxy resin (encapsulation of electronic components, insulation layer).
