Coding and Marking System
Contact Sales at Lead Tech Team
Different laser printers have different application fields. For example, the packaging of the medicine box we saw is printed with a CO2 laser printing machine, while many metal or PE pipes are only suitable for fiber laser printing. Printer printing. Why metal materials can only be marked with fiber laser printers? Today, the cij printer manufacturer Technology Co., Ltd. explains from the working principle of fiber laser printers why metal materials can only be marked with fiber laser printers. Mark, but the CO2 laser printer is not suitable?
Manufacturer Technology Co., Ltd. Fiber laser printer is a kind of laser coding equipment. The main components are fiber laser generator, galvanometer optical system, software control system, power supply system, etc. Partial composition. As the core component of the fiber laser printer, the fiber laser generator emits a laser with a wavelength of 1064 nanometers, and the beam is deflected by the polarizer system to form a mark on the product surface, which can be used for static or flying marking. The focusing lens of the laser machine produces the necessary spot for marking. The flat-field focusing lens determines a specific marking area, and marking is performed in the specific marking area. Each focusing lens has its specific focal length.
From the working principle of the fiber laser printer, it can be seen that when the fiber laser printer is working, the laser beam moves at a high speed through the laser head, usually expressed in IPS (inches per second). At the same time, the marking speed of the fiber laser printer can also be used to control the depth of marking. For a specific laser intensity, the slower the speed, the greater the depth of marking or marking. Therefore, when using the laser printer The speed can be adjusted by the panel of the marking machine, or by the printer driver of the computer, usually in the range of 1% to 99.9%, and the adjustment range is 1% each time. Of course, the fiber laser printer can also adjust the spot size of the beam. The spot size of the laser beam can be adjusted by lenses with different focal lengths: the lens with a small spot is used for high-resolution marking or high-speed dynamic marking. The spot lens is used for lower resolution marking, but for vector marking, it is an ideal choice. Therefore, the fiber laser printer can mark metals and a variety of non-metallic materials, and is more suitable for applications that require finer and higher precision: such as electronic components, integrated circuits (IC), electrical appliances, mobile phone communications, hardware Products, tool accessories, precision instruments, glasses and watches, jewelry, auto parts, plastic buttons, building materials, PVC pipes, etc.
Therefore, the fiber laser printing machine has the following advantages in marking metal materials: the marking is long-term and will not fade due to environmental factors (touch, acid and gas, high temperature, low temperature, etc.).
The anti-counterfeiting is very strong, and it is not easy to imitate and change. Moreover, the marking work of the fiber laser printer is processed by a non-mechanical 'light knifeThere is no corrosion to the working surface, no 'tool' wear, no poison, no pollution, wide applicability, and it is suitable for marking processing of a variety of materials. At the same time, the fiber laser printer has high marking accuracy, fine graphics, clear markings, long-lasting, beautiful, and low operating cost. The processing efficiency of fiber laser marking is high, the laser beam can move at a high speed (speed up to 5-7 m/s), the marking process can be completed within a few seconds, and the user can achieve laser print output by programming on the computer, and can be changed at any time Print design.
