Laser Marking Technology
Mark (Mark) when the word signs, carved standard, the depiction of marks, marking, printing, stamps, trademarks, and so synonymous with its meaning: a specific mark logo, which is to say the attribution of things, product manufacturing , Type, class, type, quality, size, time, measurement, detection, audit, inspection, notarization, and so on.

In addition, the modernization of production management from the point of view, "tags" There are a few:
Facilitating the raw materials, semi-finished products, products, product classification, management at different levels, transportation, processing, packaging and testing. In modern industrial production, tons of raw materials, components into a million have mixed (mixed type, such as mixed, mixed level) hard to imagine the consequences when, one by one will not be able to pick them out of the reclassification, classification, Classification.

To facilitate the sale. Consumers would like to "brand-name goods", "quality" and "genuine" is the sales department to die, if only all trademarks, there is no model, there is no hierarchy, no "qualified" and the date of production of goods, it is difficult to sales Out.

User-friendly. There are models, specifications, class, date, the user can easily use their respective properties, such as free medical thermometer scale can not be used.

To prevent counterfeiting. Generally have a good product in accordance with the provisions of the national trademark symbol, including graphics, text, color and so on. In order to prevent counterfeiting, in addition to use of trademarks, but also widely used in mechanical, physical, chemical, electric approach to the marking of the product, such as in the product or packaging bags print a logo on the model, text, special play Tag, cover seal, Seal hit, molded steel convex design, template printing, dyeing and printing text and images, ink-jet printing, rubber rotary India and paste printed cloth, plastic, metal membrane trademarks, in ceramic or glass color burn out Patterns or patterns of chemical corrosion, metal products for corrosion or play word electronic bombardment method or methods of coating pattern with different colors of the plating film, print or suppress the code symbols. Since the laser technology and holographic technology, also used the method described laser tag marked with the letter patterns. Use advanced science and technology is an inevitable tags choice.

The basic principles of

Laser Marking laser beam is used in a variety of material on the surface marked with a permanent marker. Hit the target effect through evaporation of surface material exposed deep-seated material, or lead to light through the surface material of the chemical and physical changes, "carved out" signs, or light burned through some of the material, show motifs required for the etching, Text.

At present, is a recognized principle of two ways:

"Hot" with high energy density of the laser beam (which is focused on the energy flow), exposure in the processing of materials on the surface, the surface of the material to absorb laser energy in the region arising from exposure to heat stimulate the process so that the surface of the material (or Coating) temperature rise, resulting in abnormal, melting, ablation, evaporation and so on.

"Cold" with high energy load (UV) photons, can interrupt materials (especially organic materials) or within the media around the chemical bonds to make the material non-thermal process of destruction. This cold laser tag in the processing of special significance because it is not a thermal ablation, but do not have a "thermal injury" of side effects, the chemical bond breaking off the cold, which was on the surface of the floor, and not in the vicinity of the region Generate heat or heat distortion effects. For example, the electronics industry in the use of excimer laser in the substrate materials on chemical film deposition, semiconductor-chip out of the narrow groove.

Different methods of marking

And ink-jet marking method, laser marking groove) is the superiority: wide range of materials (metal, glass, ceramics, plastics, leather, etc.) will be marked with a permanent marker of quality. No force on the surface, do not have a mechanical deformation of the surface of non-corrosive material (see table below)
