As companies pay more and more attention to brand promotion and product traceability, making permanent markings on the surface of products has become a popular method. There are usually two options for permanent marking of patterns on the product surface: pneumatic marking and laser marking. When choosing a marking method, users often ask, which marking method is more suitable for me? We will introduce their respective features in this article so that you can properly select the marking equipment that suits your needs.
What is a pneumatic marking machine? How does it work?
Pneumatic marking machine is the use of computer-controlled printing needle in the X, Y two-dimensional plane according to a certain trajectory of movement at the same time, the printing needle under the action of compressed air to do high-frequency impact movement, so as to print out a certain depth of the mark on the workpiece.
Pneumatic marking machine through the LOGO characters to be printed, two-dimensional code graphics and other content into the computer, the use of computer marking software to convert the content into digital control signals, transmitted to the controller to drive printing, so as to print out on the workpiece by a continuous dot matrix of characters and graphics. The printing needle moves in the X-Y two-dimensional plane according to the set trajectory, and at the same time prints a concave mark consisting of a dense dot matrix on the surface of the workpiece under the action of compressed air.
Features of Pneumatic Marking Machine
Advantages: The biggest advantage of pneumatic marking machine is that the price is cheap, generally within X dollars. Simple operation, low power consumption, long life.
Disadvantages: noise, long time use is easy to damage the operator's hearing; because pneumatic marking has a depth requirement, marking a character takes 1-5 seconds or longer, so the marking on metal is slower and takes longer than laser marking; application range is small, can only process the hardness of the metal and non-metallic materials below HRC60, marking of hard metals is difficult; can not be designed, can only mark fixed of letters and numbers; pneumatic marking is through the printing needle and workpiece contact marking, so the printing needle will cause wear and tear, every now and then to be replaced, high cost of consumables.
Application of pneumatic marking machine
Pneumatic marking machine can be used for marking various mechanical parts, machine tools, hardware products, metal pipes, gears, pump bodies, valves, fasteners, steel, instruments and meters, electromechanical equipment and other metal and non-metal marking.
What is a laser marking machine? How does it work?
A laser marking machine uses a laser beam to permanently mark the surface of a variety of different materials. The principle of marking is to reveal the deeper material through the evaporation of the surface material, thus engraving beautiful patterns, trademarks and text.
Features of laser marking machine
Advantages: laser marking machine uses laser to complete the pattern marking, which is a non-contact marking process, on the one hand, will not produce supplies, on the other hand, will not cause wear and tear on the appearance of the workpiece; laser marking the minimum line width of up to 0.01mm, marking the pattern is very fine, more beautiful; laser marking machine is equipped with professional marking software, you can design and modify a variety of patterns, in addition to two-dimensional code The laser marking machine is equipped with professional marking software, which can design and modify a variety of patterns, in addition to the two-dimensional code, production date and other simple patterns, but also on the surface of the material engraved figure, craft painting and other complex designs.
Disadvantages: Compared to pneumatic marking machines, laser marking machines are more expensive, often more than 2000 U.S. dollars.
Application of laser marking machine
Laser marking machine is suitable for both metal and non-metal, and its high precision features make it possible to apply to some occasions that require higher fineness 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 of laser marking machine and pneumatic marking machine, I believe you have a preliminary judgment on which marking equipment to use. If you want to mark a large depth or low budget, you can choose pneumatic marking machine in the case of not high requirements for marking accuracy. If you are more in pursuit of the fineness and beauty of the pattern, or if there is a large-scale marking needs, laser marking machine to meet your requirements.
