What are the characteristics of laser marking machine?

laser marking machines are used to mark the surfaces of various substances permanently with laser beams. Marking effect is through the evaporation of surface material exposed deep material, so as to carve out exquisite patterns, trademarks and words, laser marking machine is mainly divided into CO2 laser marking machine, semiconductor laser marking machine, fiber laser marking machine and YAG laser marking machine, laser marking machine is mainly used in some requirements of more fine, higher precision occasions. Used in electronic components, integrated circuit (IC), electrical appliances, mobile phone communication, hardware products, tools and accessories, precision instruments, glasses clocks and watches, jewelry, auto accessories, plastic keys, building materials, PVC pipe.

So what are the characteristics of laser marking machine? There are two widely recognized principles: “thermal processing” has a higher energy density of laser beam (it is a concentrated energy flow), irradiation on the surface of the processed material, the material surface absorbs laser energy, thermal excitation process in the irradiation area, so that the surface of the material (or coating) temperature rise, produce abnormal, melting, ablation, evaporation and other phenomena.

“Cold working” has a high energy load of (ultraviolet) photons, which can break chemical bonds in materials (especially organic materials) or surrounding media to the point of non-thermal process destruction of the material. This kind of cold processing has special significance in laser labeling processing, because it is not thermal ablation, but does not produce “thermal damage” side effect, break the chemical bond cold peeling, so the inner layer of the processed surface and the nearby area does not produce heating or thermal deformation. For example, excimer lasers are used in the electronics industry to deposit thin films of chemicals on a substrate, creating narrow slots in a semiconductor substrate.

Comparison of different marking methods Compared with inkjet marking method, laser marking engraving has the advantage of a wide range of applications, a variety of substances (metal, glass, ceramics, plastics, leather, etc.) can be marked with permanent high quality. No force on the workpiece surface, no mechanical deformation, no corrosion on the surface of the material.

Product application can carve a variety of non-metallic materials. Used in garment accessories, pharmaceutical packaging, wine packaging, building ceramics, beverage packaging, fabric cutting, rubber products, shell nameplate, craft gifts, electronic components, leather and other industries. 1. Can carve metal and a variety of non-metallic materials. More suitable for some requirements of fine, high precision product processing. 2. Used in electronic components, integrated circuit (IC), electrical appliances, mobile phone communication, hardware products, tools and accessories, precision instruments, glasses clocks and watches, jewelry, auto accessories, plastic keys, building materials, PVC pipe, medical equipment and other industries. 3. Applicable materials include: Common metals and alloys (iron, copper, aluminum, magnesium, zinc and all other metals), rare metals and alloys (gold, silver, titanium), metal oxides (all kinds of metal oxides are acceptable), special surface treatment (phosphating, aluminum anodizing, electroplating surface), ABS materials (electrical supplies shell, daily necessities), ink (transparent keys, printing products), Epoxy resin (encapsulation, insulating layer for electronic components).
