When we walk into the dazzling shopping malls, we find that many commodities have been marked, even the mineral water, ceramic cups, metal insulated cups, snack bags and cosmetic boxes we usually drink have been marked, which indicates that the laser marking machine has been widely used in our lives; However, not only the laser marking machine can have the marking function, but also the pneumatic marking machine. What is the difference between the two?
1. Different principles
The principle of the laser marking machine is to use the laser beam with high energy density under the control of the computer to irradiate on the surface of the product, so that the product surface is instantly melted or vaporized, leaving the desired pattern on the product surface.
The principle of pneumatic marking machine is to input the contents of Chinese and English characters and graphics into the computer first, and then the computer will convert them into digital signals and send them to the controller. Then, under the action of compressed air, the marking needle will make high-frequency micro impact movement to hit the surface of the product, leaving concave marks on the surface of the product.
2. Different scope of application
The laser marking machine can be applied to metal and nonmetal. At present, it is mainly used in some occasions that require more precision and higher precision, such as electronic components, integrated circuits (IC), electrical appliances, mobile phone communications, hardware products, tool accessories, precision instruments, glasses and watches, head ornaments, auto accessories, plastic keys, building materials, PVC pipes.
Pneumatic marking machines are mostly used for metal, and a few are used for non-metal (must be non-metallic with high hardness), such as various mechanical parts, machine tools, hardware products, metal pipes, gears, pump bodies, valves, fasteners, steel, instruments, electromechanical equipment and other metal marking.
In addition to the above two differences, the price also has a certain gap; Because laser marking machine needs laser, the price of laser marking machine is more expensive than that of pneumatic marking machine; You can choose according to your own needs. If you want to print deep marks on metal, you can choose pneumatic marking machine. If you want beautiful and high precision products, you can choose laser marking machine.
