QR codes now appear frequently in our lives. Many people don't know what the use of such a square black thing is. In fact, QR codes are a kind of information, which is called two-dimensional bar codes. Store some information that computers can recognize through different pattern characters.

  QR codes can store a lot of information, which can be used as a new means of publicity and marketing, and are now being used by more and more manufacturers. In fact, the printing of QR code is also very easy, with ordinary laser marking machine can easily print in batches. Advantages of QR code laser marking machine:

  1) non-contact processing: no contact with the surface of the object can be printed, so there is no damage to the object.

  2) materials are widely used: can be printed on metals, plastics, ceramics and other materials, widely used.

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

  4) mark is clear, durable, beautiful, and can be effective anti-counterfeiting; for QR code, can be effective for a long time without breakage.

  5) long service life, no pollution; will not produce any waste gas, waste water.

  6) operation cost can be low plug-in, according to the size of different, the number of watts is also different, generally low. The marking speed is fast and the marking is formed once, the energy consumption is small, so the running cost is low. This needs to hit the two-dimensional code manufacturers to save a lot of cost.

  7) processing efficiency is high: the laser beam under computer control can move at high speed (speed up to 5——7 m / s), and the marking process can be completed in a few seconds. Printing of a standard computer keyboard can be done in 12 seconds. The size of a two-dimensional code is so large.

  8) development speed: because of the combination of laser technology and computer technology, users can realize laser printing output as long as they program on computer, and can change printing design at any time, which fundamentally replaces the traditional mold making process. It provides convenient tools for shortening product upgrade cycle and flexible production. Enter the computer directly according to the pattern of the two-dimensional code.

  9) machining accuracy is high: laser can act on the surface of the material with a very fine beam, the thinnest line width can reach 0.05 mm. For precision processing and increase anti-counterfeiting function to create a broad application space. Laser printing can meet the need to print a large amount of data on very small plastic parts. For example, two-dimensional bar codes, which require more precision and clarity, are more competitive in the market than imprint or jet marking. Accurate multi-dimensional code is very important to ensure the integrity of two-dimensional code printing can be more effective.

  10) Low maintenance cost: laser marking is non-contact marking, unlike the template printing process has limited service life, in batch processing maintenance costs are extremely low.

  11) Environmental protection: laser marking for non-contact marking, energy saving, relative to corrosion method, avoid chemical pollution; relative to mechanical marking, can also reduce noise pollution.
