Fiber laser marking technology is a new type of marking technology that is gradually changing the pattern of traditional product marking, bringing revolutionary production efficiency and quality improvement to the manufacturing industry. Let's explore how fiber laser marking technology is transforming our product identification.
一. The basic principle of fiber laser marking
Fiber laser marking uses a high-energy density laser to locally irradiate the workpiece, and generates high-energy laser beams through fiber lasers, which form extremely small spots under the action of focusing mirrors, which in turn produce instantaneous thermal effects on the surface of the material. This thermal effect causes changes in the molecular structure of the material's surface, forming permanent markers.
二. How to change product identification
1. Environmentally friendly: Compared to traditional inkjet marking, the laser marking process does not require the use of any consumables, reducing environmental pollution.
2. Improve product anti-counterfeiting: Since fiber laser marking technology can form permanent marks on products that are difficult to replicate, it can improve the anti-counterfeiting performance of products and protect the rights and interests of consumers.
3. Improve product aesthetics: Fiber laser marking technology can achieve various complex patterns and text markings, making the product appearance more beautiful and exquisite.
4. Streamlined Production Process: Fiber laser marking machines can seamlessly connect with production lines, enabling automated production, reducing manual operations and improving production efficiency.
三. Specific application examples
1. Electronics: Label the circuit board or phone case with serial numbers, brand logos, or UDI codes.
2. Automotive Parts: Used to mark engine parts with model number, manufacturer information, or safety certification marks.
3. Pharmaceuticals: Label drug packaging with production lot numbers, expiration dates, or other regulatory information.
4. Luxury: Precise engraving of delicate brand logos or personalized messages on jewelry or watches.
5. Food products: Label packaging materials with production dates, batch numbers, or traceability codes.
6. Construction Materials: Mark metal or plastic pipes, sheets, or manufacturer information with specifications, grades, or manufacturer information.
In short, fiber laser marking technology, with its unique advantages and characteristics, is gradually changing the way we mark our products. With the continuous development and improvement of technology, it is believed that fiber laser marking will play a more important role in the field of industrial marking in the future.
四.Fiber laser marking machine is used
File import and parameter setting: Import the patterns, text, QR codes, etc. to be marked through special software (such as EzCad), and set the laser power, marking speed, engraving depth and other parameters according to the material (metal/plastic/ceramic, etc.) and effect (light engraving/deep engraving/color change).
Positioning and focusing: Fix the workpiece to be marked on the table, determine the marking position through the red light preview function of the equipment, and then adjust the height of the laser head to complete the focus to ensure that the laser beam is accurately focused on the material surface.
Start marking: After confirming that the parameters and position are correct, start the device, and the laser will output a specific wavelength (mostly 1064nm) laser under the control of the software, and after being reflected by the galvanometer system, it will quickly scan the material surface according to the preset trajectory.
Completion and inspection: After marking, remove the workpiece, check the clarity and integrity of the mark, and confirm that it meets the requirements before entering the next batch of operations.
To put it simply, it is similar to "using a precise laser 'pen' to 'draw' marks on materials that cannot be erased", which is different from traditional ink coding and has the characteristics of no consumables, high accuracy and high speed.
