1. Light Source
Fiber laser marking machines use a fiber laser as the light source, with the laser beam delivered through an optical fiber. CO2 laser marking machines use a carbon dioxide gas laser, which generates laser light through gas discharge.
2. Performance Characteristics
Fiber laser marking machines:
High conversion efficiency and good beam quality, resulting in high marking precision and fast marking speed.
Fiber delivery allows convenient long-distance transmission and high flexibility, making them suitable for various working environments.
Lower maintenance cost, stable operation, and long service life.
CO2 laser marking machines:
Good performance in the visible light region, producing clear marks and fine lines.
Suitable for marking a wide range of materials, including metals, non-metals, and paper.
Due to the nature of gas discharge, the equipment tends to be larger, and large-area marking may require greater investment.
3. Application Fields
Fiber laser marking machines are widely used in industries such as integrated circuits, hardware products, plastics, and rubber. CO2 laser marking machines are more often used for non-metal materials, including paper packaging, wood cutting, and engraving. Because of their high power, they are also used in some heavy industry applications.
Since the two types differ in performance and application, users should choose according to actual needs. Technological improvements continue in both categories, so equipment performance parameters and after-sales service should also be considered when selecting a machine.
For precision non-standard mechanical components used in these marking systems, such as optical mounting brackets and galvanometer seats, Hansheng Automation provides custom machining based on customer drawings or samples, including single-piece and small-batch orders.
