QR code can be seen everywhere in our life now. Many people don't know what the use of such a square and black thing is. In fact, QR code is a kind of information. It is called two-dimensional bar code. It stores some information that can be recognized by computers through the difference of pattern characters. The simple and common one is bar code.

QR code can store a lot of information, so it can be used as a new means of publicity and marketing, and has been used by more and more manufacturers. In fact, the printing of two-dimensional code is very easy, and batch printing can be easily carried out with optical fiber laser marking machine. Advantages of two-dimensional code laser marking machine:

1) Non-contact processing: It can be printed without touching the object surface, so it will not cause damage to the object at all.

2) Wide range of materials: it can be printed on metal, plastic, ceramic and other materials, and has a wide range of applications.

3) It can be integrated with other equipment on the production line to improve the automation of the production line.

4) The mark is clear, durable and beautiful, and can effectively prevent counterfeiting; For two-dimensional code, it can be effective for a long time without damage.

5) Long service life and no pollution; No waste gas or waste water will be generated.

6) Low operation cost, just plug in. The marking speed is fast and the mark is formed at one time, with low energy consumption and low operation cost. It greatly saves costs for manufacturers.

7) High processing efficiency: the laser beam under computer control can move at a high speed (up to 5-7 meters/second), and the marking process can be completed in seconds. The printing of a standard computer keyboard can be completed in 12 seconds. A QR code is just that big.

8) Fast development speed: due to the combination of laser technology and computer technology, users can realize laser printing output as long as they program on the computer, and can change the printing design at any time, and directly input it into the computer according to the style of two-dimensional code. It fundamentally replaces the traditional mold manufacturing process and provides a convenient tool for shortening the product upgrading cycle and flexible production.

9) High processing accuracy: the laser can act on the material surface with extremely fine beam, and the line width can reach 0.05mm. It has created a wide application space for precision machining and increased anti-counterfeiting function. Laser marking can meet the need of printing large amounts of data on very small plastic parts. For example, it can print two-dimensional barcode with higher accuracy and clarity, which has stronger market competitiveness compared with embossing or jet marking. Accuracy is very important for QR code, and it is more effective to ensure the integrity of QR code printing.

10) Low maintenance cost: laser marking is non-contact marking, unlike the template marking process, which has service life limitations, and the maintenance cost in batch processing is extremely low.

11) Environmental protection: laser marking is non-contact marking, which saves energy and avoids chemical pollution compared with corrosion method; Compared with mechanical marking, it can also reduce noise pollution.
