Laser marking technology is a more advanced technology than ink jet coding technology. The application of laser marking machine in the Chinese market is just beginning, but the development trend is rapid. The laser marking machine greatly improves the problems existing in the traditional marking machine, improves the reliability and flexibility of the equipment, and is suitable for all kinds of metal and non-metal materials. The working principle of the laser marking machine is to concentrate the laser light on the surface of the object to be marked with extremely high energy density, vaporize the material on the surface in a very short time, and accurately burn and engrave delicate patterns or characters by controlling the effective displacement of the laser beam. Therefore, the laser marking is the greenest and safest marking equipment.
The advantages of laser marking machine mainly include the following aspects:
- Reduce production costs, reduce consumables and improve production efficiency;
- The anti-counterfeiting effect is obvious, and the laser marking technology can effectively suppress the counterfeiting of product identification;
- It is conducive to product tracking and recording. The laser marking machine can print the batch number, production date, shift, etc. of the product. It can make every product get good tracking performance;
- Adding added value can make the product look higher. Enhance the popularity of product brands;
- The equipment is reliable. The laser marking (marking) machine has mature industrial design, stable and reliable performance, can work continuously for 24 hours, and the maintenance free time of the laser is more than 20000 hours. Wide temperature adaptation range (5 ℃ – 45 ℃), widely applicable to the LED industry assembly line production field;
- Environmental protection and safety. The laser marking machine does not produce any chemical substances harmful to human body and the environment. Conform to gb7247-87; Gb10320-88 standard. It is an environmental friendly high-tech product;
- The laser marking machine can print a large number of data in a very small range. The laser can mark the product material itself with a very fine beam. The printing accuracy is extremely high, the control is accurate, the printing content is clearly and perfectly interpreted, the market competitiveness is extremely strong, and the environment is safe, without any corrosiveness, completely isolated from chemical pollution, and is also a kind of intimate protection for operators, ensuring the cleanness and tidiness of the production site, It reduces the later investment and noise pollution.
From the above, we can conclude that laser marking machines have unique advantages in products requiring fine marking, and ink jet coding machines will be gradually replaced by laser marking machines.
