Eight reasons for using laser marking

laser marking technology has been applied more and more in the printing field in recent years. Laser marking can be applied to many materials, including plastic and rubber. Many customers buy low-cost products, such as glue, metal, silicon wafer and so on. Laser marking selects excellent materials and special technological means for precise production. Compared with traditional mechanical engraving, chemical corrosion, silk printing, ink printing and other methods, it has low cost, high flexibility and can be controlled by computer system. The firmness and permanence of the mark produced by laser acting on the surface of the workpiece is its outstanding feature. At present, laser marking has accounted for more than 90% of the market in the marking and printing industry. The reason why laser marking occupies such a large share is that it has the following ten advantages:

1 static verification is to measure the key components of the impact machine Permanent:

for example, the mark will not fade due to environmental relations (touch, acidic and reducing gases, high temperature, low temperature, etc.)

2. Anti counterfeiting:

the marks carved by laser marking technology are not easy to copy and change, and have strong anti-counterfeiting to a certain extent

3. Non contact:

laser marking is processed with a non mechanical "light knife", which can print marks on any regular or irregular surface, and the workpiece will not produce internal stress after marking, so as to ensure the original accuracy of the workpiece. No corrosion to the working surface, no "tool" wear, no poison and no pollution

4. Wide applicability:

it can process a variety of metal and non-metallic materials (aluminum, copper, iron, wood products, etc.) by using exciting one-day light as processing means

5. High engraving accuracy:

the article engraved by the laser marking machine has fine lines, and the minimum line width can reach 0.04mm. The mark is clear, durable and beautiful. Laser marking can meet the needs of printing a large amount of data on very small plastic parts. For example, two-dimensional bar codes that require more accuracy and higher definition can be printed, which has stronger market competitiveness compared with embossing or jet marking

6. Low operation cost:

the marking speed is fast and the marking is formed at one time, with low energy consumption, so the operation cost is low. Although the equipment investment of laser marking machine is larger than that of traditional marking equipment, the operation cost of using laser marking machine is much lower. For example:

① marking of plastic sealed triode: the working speed of the marking machine is 10/s. if the equipment depreciation is calculated as 5 years, the marking cost is 0.00048 yuan/piece. If the pad printing machine is used, its comprehensive operation cost is about 0.002 yuan/piece, or even higher

② bearing surface marking: if the bearing is typed in three equal parts, with a total of 18 No. 4 characters, using a galvanometer marking machine, and the service life of the krypton lamp tube is 700 hours, the comprehensive marking cost of each bearing is 0.00915 yuan. The cost of electroetching engraving is about 0.015 yuan/piece. Based on the annual output of 4million sets of bearings, only marking one item can reduce the cost by about 65000 yuan at least in one year

7. High processing efficiency

the laser beam controlled by the computer can move at a high speed (up to 5 ~ 7 m/s), and the marking process can be completed in a few seconds

8. Fast development speed

due to the combination of laser technology and computer technology, users can realize laser print output as long as they program on the computer, and can change the print design at any time, which fundamentally replaces the traditional mold making process, and provides a convenient tool for shortening the product upgrading cycle and flexible production.
