Laser marking: a precise tool for modern manufacturing

Posted by

Laser marking technology, as one of the important applications in the field of laser processing, is playing an important role in all walks of life with its unique advantages. This technology uses high-energy-density lasers to locally irradiate the workpiece, causing the surface material to vaporize or undergo a chemical reaction that changes color, thereby leaving a permanent mark. It not only achieves efficient and precise processing of materials, but also meets the needs of modern manufacturing for high quality, high efficiency and pollution-free.

Technical characteristics of laser marking
High precision and details: Laser marking can produce fine text, symbols and patterns from millimeters to microns, and its engraving accuracy is extremely high, which is of great significance to product anti-counterfeiting. Especially in the fields of microelectronics industry and bioengineering, laser marking technology can achieve sub-micron-level marking, providing strong support for high-precision manufacturing.
Wide applicability: Laser marking can process almost all materials, including metals, plastics, glass, ceramics, wood, leather, etc. This makes laser marking technology have broad application prospects in various fields.
Non-contact processing: Laser marking is a non-contact processing that avoids mechanical stress and physical damage, and is particularly suitable for processing easily deformed or brittle materials.
Efficiency and environmental protection: The laser marking process does not require consumables and does not cause environmental pollution. It is a clean and pollution-free processing method. At the same time, its high-speed marking capability can significantly improve production efficiency and meet the needs of modern production for high efficiency and fast pace.
Flexibility and automation: Laser marking machines can be combined with computer numerical control technology to form efficient and automated processing equipment. By designing and engraving patterns through software, it becomes easy to change the marking content, meeting the personalized needs of different industries and customers.
