Pneumatic marking machines and laser marking machines are usually used for metal material marking. According to different marking contents, suitable marking equipment can be selected to process and produce the products. Date, production specification, QR code and other information.
Pneumatic marking machine is a computer-controlled printing needle moving in a certain trajectory in the X, Y two-dimensional plane, while the printing needle performs high-frequency impact movement under the action of compressed air, so as to print a mark with a certain depth on the workpiece. Laser marking machine is a marking equipment that uses different lasers to hit the laser beam on the surface of various materials, and make the surface material undergo physical or chemical changes through light energy, thereby engraving permanent marks such as patterns, trademarks and text.
The power of the pneumatic marking machine comes from high-pressure gas. Under the impetus of air pressure, the metal needle of high-hardness alloy is used to perform high-frequency impact on the metal material, thereby forming characters and patterns. The laser marking machine adopts non-contact processing without touching the surface of the metal material, and has no damage to the material, but also has the characteristics of high marking accuracy, fast speed, and permanent marking.
Metal material laser marking machine generally refers to fiber laser marking machine, which is characterized by high marking accuracy, fast speed and stable performance. It only needs to be controlled by computer, and the operation is simple. It can print various complex patterns, text, Two-dimensional code and other content, its marking advantages in metal materials are as follows:
1. Non-contact processing, no internal stress
Laser marking is processed by a non-mechanical "light knife", which can print marks on any regular or irregular surface, and the workpiece will not generate internal stress after marking, ensuring the original accuracy of the workpiece. No corrosion, no wear, no poison, no pollution to the working surface.
2. Low operating cost, high precision marking
The metal laser marking machine marks a molding, the marking speed is fast and the energy consumption is small, so the operating cost is low. Although the equipment investment of a laser marking machine is larger than that of traditional marking equipment, in terms of operating costs, using a laser marking machine is much lower. Compared with traditional processing methods, laser marking machines are especially suitable for marking complex graphics due to their high-precision characteristics. The marking speed is fast and the marking is formed at one time, which greatly broadens its application range.
3. Wide range of applications and easier operation
The laser marking machine has low requirements on the processing material, shape, size and processing environment, and can produce good marking effects on some 3D curved surfaces or workpieces on the assembly line. It can mark a variety of metals, non-metals and alloy materials with very good durability, a wide range of applications, and the marks are not easy to erase. The operation is simple and easy to learn, and technicians can learn it in a short time.
