In recent years, the application of fiber laser marking machine in the printing field is more and more, fiber laser marking machine can be applied to a variety of materials, including plastic and rubber, metal, silicon wafer, etc. Compared to the laser calibration and traditional mechanical engraving, chemical etching, screen printing, printing ink, etc., with low cost, high flexibility, computer control system, and laser action on the surface of the workpiece is generated from labeled strong permanent is its outstanding characteristics. At present, in the marking printing industry, laser marking has occupied more than 90% of the market. Fiber laser marking machine has such a large share, because it has the following eight major advantages:
Such as marks will not be due to environmental relations (touch, acid and reducing gas, high temperature, low temperature, etc.).
2. Anti fake
It is not easy to copy and change the mark which is carved by laser marking technology, and it has a strong anti fake ability to a certain extent.
3. Non contact
Laser marking is processed in non mechanical "knife", can be in any regular or irregular surface print labeling and marking the workpiece does not generate internal stress and guarantee the workpiece original precision. No corrosion on the working surface, no "tool" wear, no poison, no pollution.
4. Wide applicability
Using laser processing tools, can be a variety of metal, non-metallic materials (aluminum, copper, iron, wood products, etc.) processing.
5. High engraving precision
Laser marking machine engraving of fine grain, the smallest line width of up to 0.04mm. Mark clear, durable, beautiful. Laser marking can meet the needs of printing a large number of data on a small plastic part. For example, can be printed for more accurate, higher definition of two-dimensional bar code, compared with the impression or jet marking, there is a stronger market competitiveness.
6. Low operating cost
Marking speed is fast and the marking is formed at one time, the energy consumption is small, so the operation cost is low. Although laser marking machine equipment investment is larger than the traditional marking equipment, but from the operation cost using laser marking confidential much lower. For example:
a. Plastic triode tube marking, marking machine working speed is 10 / s, if the depreciation of equipment in 5 years, marking fee for 0.00048 yuan / month. If the use of printing machines, the overall operating costs of about 0.002 yuan / month, or even higher.
b. Bearing surface marking: Typing equal Waka Chengmi, at a total of 18 4 words, the galvanometer based marking machine, to the service life of the krypton lamp for 700 hours, then each bearing a marking comprehensive cost is $0.00915. Electric corrosion lettering costs about 0.015 yuan / month. The annual output of 4 million sets of bearings, only a standard, 1 years can reduce the cost of about $.
7. High processing efficiency
Under the control of the laser beam can be high-speed mobile (speed of 7 ~ 5 m / s), marking the process can be completed within a few seconds.
8. Fast development
Because of the combination of laser technology and computer technology, the user can realize the laser print output and change the printing design at any time, which can replace the traditional mold making process. This provides a convenient tool to shorten the cycle of product upgrading and flexible production.
