What materials can a CO2 galvo laser mark?

Introduction

CO2 galvo lasers are widely utilized in various industries for their ability to precisely mark a diverse array of materials. Their versatility and efficiency make them an excellent choice for applications requiring high-speed and high-precision marking.

Materials Marked by CO2 Galvo Lasers

CO2 galvo lasers are capable of marking a broad range of non-metallic materials. Due to their high wavelength, they interact effectively with organic materials and certain synthetic substances. The following list outlines the materials commonly marked using CO2 galvo lasers:

• Wood: CO2 lasers are effective for engraving detailed patterns and designs on various wood types, including hardwoods and softwoods.
• Glass: The laser can produce frosted designs without fracturing the glass surface.
• Plastics: Common plastics like acrylic, polycarbonate, and PVC can be marked clearly, provided they do not contain chlorine, which may release harmful gases.
• Textiles: CO2 lasers can cut and engrave precise patterns on natural fibers like cotton and synthetic fabrics such as polyester.
• Leather: High precision and speed allow for intricate designs on leather without compromising the material’s integrity.
• Ceramics: Glazed ceramics can be etched with precise designs through the glaze without compromising the material.
• Rubber: CO2 lasers are used for marking vulcanized rubber and creating molds for rubber stamps.

Key Parameters for Effective Marking

Achieving optimal results when marking with CO2 galvo lasers requires an understanding of key operational parameters. Some critical factors include:

• Laser Power: Higher power settings (typically 30W to 120W) are necessary for deeper engravings and thicker materials.
• Speed: The marking speed (up to 7,000 mm/s) should be adjusted based on the material and desired marking depth, with slower speeds yielding deeper marks.
• Frequency: Adjusting the pulse frequency can improve the marking quality on different materials, with settings ranging from 1 kHz to 100 kHz.
• Focus Distance: Maintaining the correct focal distance (usually 2 to 10 mm) ensures precision and prevents distortions.
• Spot Size: A smaller spot size allows for finer details, with typical spot diameters ranging from 0.1 mm to 0.25 mm.
