Hello, glad to get back to you:
First, laser marking machine is the use of laser beams in a variety of different substances on the surface of a permanent mark.
The effect of marking is through the surface material evaporation to reveal the deep material, or through the light energy to cause chemical and physical changes in the surface material and "carve" traces, or through the light energy to burn off part of the material, revealing the required etching patterns, text.
Second, laser marking machine specific applications in many industries, as follows:
1, automotive machinery industry: bearings, steel bushings, piston rings, engines, vehicle signage and machine tools, etc.;
2, electronic communications industry: cell phones, keyboards, electronic components, home appliance panels, fiber optic cables, cables, etc.
3, hardware and equipment industry: the first two are the same as the second, the first is the same as the first.
3, hardware equipment industry: tools, measuring tools, cutting edge, sanitary ware, tableware, locks, knives and scissors, medical equipment, fitness equipment, stainless steel products, etc.;
4, buttons and tags industry: buttons, luggage buckles, belt buckles, gold and silver jewelry, signs, badges, time and attendance cards, business cards, photographs, purses, belts, pens and pen cases, collectors, works of art, etc.;
5, Instrument glasses industry: metal cases, table bottom, eyeglass frames, instrument panels, etc.;
6, wood craft industry: wooden handicrafts, paintings and calligraphy reproduction and mounted table, furniture craft decorations, etc.;
7, packaging cap industry: tobacco, food, drugs, cosmetics, etc., inside and outside the packaging, metal bottle caps, furniture decorations, buttons and tags, plastic products.
Third, the use of laser marking machine benefits are:
1, permanent: ? Such as marking mark will not fade due to environmental relations (touch, acidic and attenuating gases, high temperature, low temperature, etc.).
2, anti-counterfeiting:? Using laser marking technology engraved mark is not easy to imitate and change, to a certain extent, has a strong anti-counterfeiting.
3, non-contact:? Laser marking is a non-mechanical "light knife" for processing, can be printed on any regular or irregular surface marking, and marking the workpiece will not produce internal stress, to ensure that the original precision of the workpiece. No corrosion on the work surface, no "tool" wear, non-toxic, non-polluting.
4, wide applicability:? Laser processing means, can be a variety of metal, non-metallic materials (aluminum, copper, iron, wood products, etc.) processing.
5, high precision engraving:? Laser marking machine engraved items fine pattern, the minimum line width of up to 0.04mm. marking clear, durable, beautiful. Laser marking can meet the need to print a large amount of data on a very small plastic parts. For example, it can print two-dimensional barcodes that require greater precision and clarity, and has stronger market competitiveness than embossing or jet marking methods.
6, low running costs:? Marking speed and marking a molding, energy consumption, and therefore low operating costs. Certainly the laser marking machine equipment investment than the traditional marking equipment, but from the operating costs, the use of laser marking machine is much lower. Examples:? ① plastic transistor marking: laser marking machine working speed of 10 / s, if the depreciation of equipment to 5 years, marking the cost of 0.00048 yuan / one. If the use of pad printing machine, its comprehensive operating costs of about 0.002 yuan / a, or even higher. ② bearing surface marking: if the bearing three equal parts of the typing, total **** 18 No. 4 words, the use of vibrating mirror type marking machine, to the krypton lamp lamp life of 700 hours of calculations, then the marking of each bearing the comprehensive cost of 0.00915 yuan. The cost of electrocorrosion engraving is about 0.015 yuan / one. With an annual output of 4 million sets of bearings, only marking one, 1 year at least can reduce the cost of about 65,000 yuan. ?
7, high processing efficiency: computer-controlled laser beam can move at high speed (speed up to 5 ~ 7 m / s), marking process can be completed within a few seconds.
8, fast development: due to the combination of laser technology and computer technology, the user can achieve laser printout as long as the computer programming, and can be changed at any time to print the design, fundamentally replacing the traditional mold making process, to shorten the product upgrading cycle and flexible production provides a convenient tool.
