Two-dimensional code can store a large amount of data, and its readability and reliability are high. It has become an indispensable part of automatic product tracking, and it is slowly being used by more and more businesses. There are dozens of two-dimensional code laser marking equipment produced by Fulan Laser, and different types of materials have different laser energy absorption rates. Some materials are easy to absorb laser energy and are easy to mark; while some materials do not absorb laser energy, high-quality marks cannot be made, or even cannot be marked.

So, do you know which model is most suitable for your product to print the QR code? Next, let's take a look at how to choose a marking machine suitable for your product with Fulan Laser.

1. Fiber laser marking machine: The wavelength is 1064nm, which is mainly used for marking metals and some non-metallic materials with harder materials and higher ignition points;

2. Green laser marking machine: wavelength of 532nm, semi-cold light source, small heat affected area, suitable for most metal and non-metal materials. It makes up for the problem that many materials are not fine enough and the effect is not good enough for fiber laser marking;

3. Ultraviolet laser marking machine: The wavelength is 355nm, all cold light source, also called cold light machine. Suitable for marking various materials. Mainly used in the high-end market of ultra-fine processing, with good beam quality, smaller focused spot, ultra-fine marking can be realized, heat affected area is very small, and no heat effect is generated;

4. Carbon dioxide laser marking machine: The laser wavelength is 10.64um, which is mainly used for marking leather, cloth, wood, bamboo, plastic, rubber, ceramics, stone, acrylic and other non-metallic materials;

5. Mopa laser marking machine: It is a special fiber laser marking machine, its wavelength is 1064nm, the same as fiber optic machine, it is mainly used for marking with metal and some non-metallic materials with harder materials and higher ignition points. But it has a function that other types of laser marking machines can't do, that is aluminum alloy and anodized aluminum black. It can perform shallow blackening effect on aluminum profiles, especially anodized aluminum, so as to achieve visual effects and permanent effects. It is fine and beautiful. The surface of the marking is smooth and has no bumps, no less than silk screen printing.

Because different types of lasers emit light of different wavelengths. The penetrating ability of different lasers is also different; and the adaptability of different lasers has an impact on the marking quality and marking speed. Therefore, the types of laser marking machines used for plastics of different materials and plastics of the same material and different purity will be different. In addition, each customer has different marking requirements. Therefore, which laser marking machine is the most suitable for your product needs to be proofed before being determined.
