Introduction

CO2 laser marking machines are a pivotal technology in industrial marking and engraving applications. These machines employ a laser beam to create permanent marks on various materials. Known for their precision and efficiency, CO2 lasers are widely used across multiple industries.

CO2 Laser Marking Technology

CO2 laser marking is a non-contact process that utilizes a CO2 gas mixture to generate a laser beam with a wavelength of approximately 10.6 micrometers. This wavelength is particularly suitable for marking organic materials such as wood, leather, and plastics, as well as marking painted or anodized surfaces.

Working Principle of CO2 Laser Marking Machines

The working principle of CO2 laser marking machines involves the following steps:

1. Laser Generation: The laser is generated within a gas-filled tube where electrical energy excites a mixture of carbon dioxide, nitrogen, and helium gases.
2. Beam Steering: Galvanometer scanners rapidly direct the laser beam across the material surface in the desired pattern.
3. Marking Process: The laser energy is absorbed by the material, causing localized heating and inducing a change in the surface characteristics to create a visible mark.

Key Components of a CO2 Laser Marking Machine

• Laser Tube: Typically made of glass or ceramic, it contains the gas mixture needed for laser production.
• Power Supply: Provides the necessary electrical energy to excite gases in the laser tube.
• Galvanometer Scanner: Controls the direction and movement of the laser beam with precision.
• F-Theta Lens: Focuses the laser beam onto the material surface for precise marking.

Advantages of CO2 Laser Marking

• High Precision: Capable of producing fine details with resolutions of up to 1,000 dpi.
• Versatility: Suitable for a wide range of materials including non-metals and coated metals.
• Efficiency: Capable of marking speeds up to 2,500 mm/s depending on the material and design complexity.
• Low Maintenance: Minimal maintenance requirements due to non-contact process and durable components.
