Laser marking technology has been used more and more in various industries in recent years. Laser marking can be applied to all kinds of metal (stainless steel, copper, zinc alloy, aluminum, etc.) and a variety of non-metallic materials (plastic, rubber, silicon wafers, etc.). Compared with traditional ink printing, mechanical engraving, chemical etching, screen printing and so on, laser marking has the advantages of low cost, high flexibility and fast speed. It can be controlled by computer software system, and the strong and permanent marking of laser generated on the surface of the workpiece is a prominent feature. At present, in marking printing industry, laser marking has occupied more than 90% of the market. There are several reasons for choosing a laser marking machine.

1. permanence: for example, marking will not fade due to environmental relationship (oxidation, high temperature, low temperature, touch, acid and reducing gases).

2. anti-counterfeiting: marking by laser marking technology is not easy to copy and change, to a certain extent, it has a strong anti-counterfeiting property.

3. non contact: laser marking is processed with a non mechanical "light knife", and can be printed on any regular or irregular surface, and the workpiece will not produce internal stress after marking, so as to ensure the original precision of the workpiece. No corrosion on the work surface, no tool wear, no toxicity and no pollution.

4., wide applicability: using laser as processing means, it can process many kinds of metal and non-metallic materials (aluminum, copper, iron, wood products, etc.).

5. engraving accuracy is high: the laser marking machine is carved with fine patterns and minimum line width can reach 0.04mm. The mark is clear, lasting and beautiful. Laser marking can meet the needs of printing large amounts of data on very small plastic parts. For example, two-dimensional barcodes, which require more precise and clearer specifications, can be more competitive than those of stamping or spray marking.

6. the operation cost is low: marking speed is fast, marking is formed at a time, energy consumption is low, and operation cost is low. Although the investment of laser marking equipment is larger than traditional marking equipment, the laser marking machine is much lower in terms of operation cost. And now laser marking machine price is very transparent, almost cabbage price.

7. high processing efficiency: laser beam controlled by computer can move at high speed (up to 5 - 7 m / sec), and the marking process can be completed in a few seconds.

8. fast development: because of the combination of laser technology and computer technology, users can realize laser printing output as long as they are programmed on the computer, and can change printing design at any time, replacing the traditional mold making process fundamentally, providing a convenient tool for shortening product upgrading cycle and flexible production.
