Introduction

CO2 lasers are widely used for marking purposes across various industries due to their versatility and efficiency. These lasers operate at wavelengths typically around 10.6 micrometers and are particularly effective for marking non-metallic materials. The following discussion details the materials suitable for CO2 laser marking, specific parameters related to the process, and highlights solutions offered by Huawo Laser Company.

Materials Suitable for CO2 Laser Marking

CO2 lasers are capable of marking a wide range of materials, primarily non-metals. The most common materials include:

• Organic Materials: Paper, cardboard, and wood are easily marked due to their high carbon content, which absorbs the CO2 laser's energy efficiently.
• Plastics: Certain plastics such as acrylic, polycarbonate, and ABS can be marked with high precision due to their suitable absorption characteristics.
• Glass: While considered challenging, CO2 lasers can effectively mark glass by creating micro-fractures on the surface.
• Textiles: Fabrics made from natural fibers like cotton and silk respond well to CO2 laser marking, allowing for intricate patterns and designs.
• Leather: Both natural and synthetic leather materials can be effectively marked for customization purposes.

Specific Parameters and Numerical Analysis

Various parameters influence the effectiveness and precision of CO2 laser marking. Critical parameters include:

• Wavelength: CO2 lasers typically operate at a wavelength of 10.6 µm, which is optimal for non-metallic materials.
• Power Output: Typical CO2 lasers range from 10W to 100W or more, with power requirements differing based on material type and thickness.
• Marking Speed: Speeds can range from 100 mm/s to 1,000 mm/s, depending on the desired depth and contrast of the marking.
• Spot Size: The laser spot size can be adjusted, typically ranging from 100 µm to 500 µm, influencing the fineness of the detail.
• Duty Cycle: Adjusting the duty cycle affects the heat input and precision, with typical cycles ranging from 10% to 90%.
