As businesses increasingly focus on branding and product traceability, making permanent markings on product surfaces has become a popular method. There are usually two options for permanently marking the pattern on the surface of the product: pneumatic marking and laser marking. When choosing a tagging method, users often ask, which tagging method is better for me? In this article, we will introduce you to their respective characteristics so that you can choose the right marking equipment for your needs.

 

The pneumatic marking machine uses the computer to control the printing needle to move according to a certain trajectory in the X and Y two-dimensional planes, while the printing needle performs high-frequency impact motion under the action of compressed air, thereby printing a certain depth of marks on the workpiece.

The pneumatic marking machine inputs the LOGO characters, two-dimensional code graphics and other contents to be printed into the computer, uses the computer marking software to convert the contents into digital control signals, and transmits them to the controller for driving and printing, so as to print on the workpiece a continuous Characters and graphics composed of dot matrix. The printing needle moves according to the set trajectory in the X-Y two-dimensional plane, and at the same time, under the action of compressed air, concave marks composed of dense lattices are printed on the surface of the workpiece.

 

Advantages: The biggest advantage of the pneumatic marking machine is that the price is cheap, generally within X dollars. Simple operation, low power consumption and long life.

Disadvantages: high noise, long-term use is easy to damage the operator's hearing; because pneumatic marking has depth requirements, it takes 1-5 seconds or more to mark a character, so the speed of marking on metal is slow and the time required Longer than laser marking; small application range, only metal and non-metallic materials with hardness below HRC60 can be processed, hard metal marking is difficult; no design, only fixed letters and numbers can be marked; pneumatic marking is done by printing needles It is in contact with the workpiece for marking, so the printing needle will cause wear and tear, and it must be replaced at regular intervals, and the cost of consumables is high.

 

Pneumatic marking machine can be used for metal and non-metal marking of various mechanical parts, machine tools, hardware products, metal pipes, gears, pump bodies, valves, fasteners, steel, instruments and meters, electromechanical equipment, etc.

 

Laser marking machine use laser beams to permanently mark the surface of various materials. The principle of marking is to expose the deep material through the evaporation of the surface material, so as to engrave exquisite patterns, trademarks and words.

 

Advantages: The laser marking machine uses laser to complete the marking of the pattern, which is a non-contact marking process. On the one hand, it will not produce consumables, and on the other hand, it will not cause wear on the appearance of the workpiece; The width can reach 0.01mm, and the marked pattern is very fine and more beautiful; the laser marking machine is equipped with professional marking software, which can design and modify various patterns, except for simple patterns such as QR code and production date, It can also engrave human figures, craft paintings and other complex designs on the surface of the material.

Disadvantages: Compared with pneumatic marking machines, laser marking machines are more expensive, often over $2,000.

 

The laser marking machine is suitable for metal and non-metal, and its high-precision characteristics make it applicable to some occasions that require higher precision and precision. Such as electronic components, integrated circuits (IC), electrical appliances, mobile communications, hardware products, tool accessories, precision instruments, glasses and clocks, jewelry, auto parts, plastic buttons, building materials, PVC pipes, food packaging.

 

Through the above introduction to the laser marking machine and the pneumatic marking machine, I believe that you have already made a preliminary judgment on which marking equipment to use. If you want to mark with a large depth or have a low budget, you can choose a pneumatic marking machine if you do not require high marking accuracy. If you are more in pursuit of the fineness and beauty of the pattern, or if you need large-scale marking, the fiber laser marking machine can meet your requirements.

 

If you can't judge which marking equipment is better, you can send the materials to be marked to the marking machine manufacturer and ask them to record a marking video, so that you can intuitively understand the performance of each marking equipment final effect. This will help you choose the right marking machine.
