Laser Marking on Metals: Exquisite Craftsmanship for Long-Lasting Durability
Metal materials and products are widely used in modern industrial production. The clarity, accuracy, and durability of their marking are crucial for product traceability and quality control. Compared with traditional marking methods such as stamping and embossing, which not only damage the flatness of metal products but also lead to problems like unclear marks and inaccurate marking positions, laser marking machines can well avoid these issues.
A laser marking machine uses a laser beam to mark the metal surface, featuring extremely high precision and efficiency. It can clearly print various numbers, symbols, text, QR codes, etc., on the surface of metal products. This marking method not only has a fast speed but also ensures that the marked results are durable and will not fade or disappear due to environmental changes or the passage of time.
In the metal product industry, laser marking machines can be used to mark information such as batch numbers, serial numbers, component content, and manufacturers. This information is essential for product quality traceability and management. Additionally, laser marking machines can realize automated marking through system software control during the production process.
In terms of the application of laser marking machines in the metal product industry, they also have significant advantages in environmental protection and energy conservation. They only consume electrical energy, with an electro-optical conversion efficiency of over 28%. Compared with traditional marking methods, they have lower energy consumption and lower operating costs. Meanwhile, laser marking machines adopt non-contact processing, which will not damage the surface of metal products nor produce any chemical pollution.
Furthermore, laser marking machines have extremely low maintenance costs. They boast advantages such as no adjustment, no maintenance, and high stability, along with a long service life. The service life of the laser, the core component, can reach tens of thousands of hours. Such high reliability and low maintenance costs make laser marking machines an ideal marking equipment in the metal product industry.
A metal marking machine is a device specially used for printing or engraving logos, text, patterns, and other marks on the surface of metal products. The following is a detailed introduction to it:
Classification and Working Principles
- Pneumatic Marking Machine: It uses compressed air to drive a piston, which in turn drives a marking needle to impact characters or graphics on the metal surface. Its marks are permanent, and it is widely used in industries such as automotive manufacturing and machinery production.
- Laser Marking Machine: It uses a high-energy laser beam to vaporize the surface material of the metal, cause chemical or physical changes, or burn off part of the material, thereby forming marks. According to different lasers, it can be divided into various types such as fiber laser marking machines, CO₂ laser marking machines, and YAG laser marking machines.
- Electrochemical Marking Machine: It applies the electrochemical principle to form marks on the metal surface through electrolytic corrosion. It is suitable for various metals such as stainless steel and aluminum alloys.

Functional Features
- High-Precision Marking: Laser marking machines can achieve fine engraving at the level of 0.01mm and accurately reproduce complex graphics such as QR codes and micro-text.
- Diversified Marking Forms: Laser marking machines support multiple marking modes such as deep engraving, shallow oxidation, and color marking, which can meet the marking needs of different products.
- Clear and Durable Marks: The marks made by pneumatic marking machines and electrochemical marking machines are standard and clear, with good wear resistance and corrosion resistance, and are not easy to fade or fall off.
- Easy Operation: For an electrochemical marking machine, you only need to place the template on the workpiece and press the output electrode for 1-2 seconds to complete the marking, making the operation process simple and fast.

Application Fields
- Automotive Industry: Used for marking automotive nameplates, engine blocks, gearbox housings, and other components, marking information such as Vehicle Identification Numbers (VIN) and production batch numbers.
- Machinery Manufacturing: Can mark various mechanical parts, machine tools and tools, hardware products, etc., indicating product models, specifications, manufacturer names, etc.
- Medical Device Industry: Mark information such as product names, models, and production dates on medical devices to facilitate product traceability and quality control.
- Electronic and Electrical Industry: Suitable for marking electronic components, integrated circuits, mobile phone middle frames, etc., marking serial numbers, QR codes, and other information.
A fiber laser marking machine is a marking method that uses a high-energy-density laser to irradiate a local area of the workpiece, causing the surface material to vaporize or undergo a chemical reaction that changes color, thereby leaving a permanent mark. It is applicable to a wide range of materials, and most metal or non-metal materials can be etched by lasers.
