Introduction

CO2 laser marking machines are pivotal in various industries for engraving and marking tasks. Unlike traditional marking techniques, CO2 lasers offer precision, speed, and durability. They are widely employed in sectors ranging from automotive to consumer goods.

Principle of CO2 Laser Marking Machine

A CO2 laser marking machine operates by utilizing a gas laser that emits a concentrated beam of infrared light. This light interacts with the material's surface, causing photothermal effects that either change the color, remove the material, or engrave the surface.

Components of a CO2 Laser Marking Machine

• Laser Tube: The core component, filled with carbon dioxide gas mixture.
• RF Excitation: Provides the necessary energy to excite the gas in the tube.
• Optical System: Includes lenses and mirrors to focus and direct the laser beam.
• Marking Head: Contains the scanning mirrors that guide the laser beam over the marking surface.
• Control Unit: Software and hardware that dictate the marking patterns and intensity.

Operating Parameters of CO2 Laser Marking Machine

Optimal operation of CO2 laser marking machines requires consideration of various parameters:

• Wavelength: Typically around 10.6 micrometers, ideal for organic and non-metallic materials.
• Power Output: Ranges from 10 to 100 watts, affecting the depth and speed of marking.
• Pulse Frequency: Adjustable from continuous to pulsed modes, depending on material sensitivity and precision requirements.
• Beam Diameter: Smaller diameters (around 0.1 mm) allow for finer detail in marking.
• Working Distance: Generally between 50 to 100 mm, influencing the focus and sharpness of the mark.
