Problems, principles and advantages of marking plastics


Author: Correct Pack -Laser Marking Machine Manufacturer

Fiber laser marking machine is a laser marking machine using fiber laser. Fiber laser marking machine has the advantages of long service life, maintenance-free, no consumables, high stability, high production efficiency, wide application range and low cost of use. At present, more and more industries are introducing and using fiber laser marking machines, so how wide is the application range of fiber laser marking machines? The marking materials of fiber laser marking machine are mainly metals and some non-metals. Its principle is to evaporate the surface layer of the object through laser to form a mark. For metal materials, most of them can be marked with fiber laser marking machine. It’s just that the effect is good or bad. For example, aluminum and copper can only be marked in white when marking on aluminum. Well, for plastic, hard plastic such as ABS is easier to mark. There are many kinds of plastic materials, generally hard, and the darker the color, the easier it is to mark with a fiber laser marking machine. So can the fiber laser marking machine mark plastic? The answer is yes, but it is conditional. Part of it can be marked, and those that do not meet the conditions cannot be marked. Can it mark different colors on plastic? Generally speaking, optical fiber The laser marking machine marks the logo. The color of the laser marking machine is the color of the material itself, but like stainless steel, the parameters can be adjusted to make the printed logo appear in various colors. Generally, the plastic can only be gray-black. You can only adjust the depth of its color, but you cannot play other colors.

Will the fiber laser marking machine burn out the plastic when marking on the plastic? The fiber laser marking machine will not burn out the plastic when marking on the plastic. The output power of the fiber laser marking machine is generally not high. As long as the parameters are adjusted properly, the laser will only evaporate a thin layer of the plastic surface without burning it. The plastic itself is damaged, so there is no need to worry about this problem, but the laser cutting machine, it is difficult to use a laser cutting machine to cut plastic in the industry without melting, yellowing, etc. Of course, this is a digression. Fiber laser marking machine marks plastic, can the mark be wiped off?

Generally not. Laser marks are generally permanent and cannot be wiped off unless the surface is scraped off. Therefore, marking the production date with a laser marking machine is still very useful for anti-counterfeiting marks. The basic principle of the laser marking machine is that the laser generator produces a high-energy continuous laser beam, which is focused on the printing material, instantly melts or even evaporates the surface material, thereby controlling the path of the laser, and forming the required graphic marks on the surface of the material. Characterized by non-contact processing, the UV laser marking machine can mark on any special-shaped surface, the workpiece will not deform and generate internal stress, and it is suitable for marking metal, plastic, glass, ceramics, wood, leather and other materials. The extremely thin laser beam behind the laser marking machine is like a tool to remove the material on the surface of the object point by point, the advanced feature is that the marking process is non-contact processing, there is no mechanical extrusion or mechanical stress, so it will not be damaged, the item, due to The focused laser has a small size, a small heat-affected area, and fine processing, which can complete processes that cannot be achieved by traditional methods. The laser used in laser processing“tool”It is the spot after focusing, no need to add additional equipment and materials, as long as the laser works normally, it can be processed continuously for a long time, the laser processing is fast and the cost is low, the laser processing is automatically controlled by the computer, no manual intervention is required in the production process, the laser can What kind of information to mark is only related to the information designed in the computer. As long as the graphic marking system designed in the computer recognizes it, the marking machine can accurately restore the design information to the appropriate carrier. Therefore, the function of the software is actually very important. The degree determines the function of the system. As a modern precision processing method, laser marking technology has incomparable advantages compared with traditional processing methods such as corrosion, EDM, mechanical scribing and printing: 1. Laser marking The machine is used as a processing method, and there is no processing force between the industrial IC automatic laser marking machine and the processing, and the processing, the workpiece has the advantages of no contact, no cutting force, and small thermal influence, thus ensuring the original accuracy of the workpiece. At the same time, It has wide adaptability to materials, can make very fine marks on the surface of various materials, and has very good durability.

Laser marking machine 2. The space controllability and time control of the laser are very good, the material, shape, size and processing environment of the object are very flexible, especially suitable for automatic processing and special surface treatment, the processing method is flexible, and can meet the laboratory type The needs of single-piece design can also meet the requirements of industrial mass production. Laser marking is fine, and the lines can reach the order of magnitude from millimeters to microns. It is very difficult to mark and modify laser marking machine technology, and product anti-counterfeiting is very important. The combination of laser processing systems Computer numerical control technology can form efficient and automatic processing equipment, which can generate various characters, symbols and patterns, facilitate software design marking patterns, change marking content, adapt to requirements, modern production, high efficiency, fast pace, and traditional screen printing Compared with laser processing, which has no pollution source, it is a clean and pollution-free high-environmental processing technology. Laser marking technology has been widely used in all walks of life, with high quality, high efficiency, no pollution, and low cost. Modern processing and production have opened up Broad prospects.
