For glass, stone, wood, and ceramics, choosing the appropriate laser marking machine depends on the characteristics of the materials and the processing requirements. Below is a detailed analysis and recommendation for each material:

1. Glass

Recommended Laser Marking Machine: UV Laser Marking Machine or Ultrafast (Femtosecond) Laser Marking Machine

• UV Laser Marking Machine:
  • Wavelength of 355nm, with concentrated energy and minimal heat-affected zones.
  • Suitable for precise markings on glass surfaces, such as QR codes, text, or patterns.
  • Does not cause cracks or thermal damage, ideal for high-precision applications.
• Ultrafast (Femtosecond) Laser Marking Machine:
  • Extremely short pulse width (femtosecond level), with highly concentrated energy.
  • Can achieve higher-quality internal engraving effects (e.g., 3D internal engraving).
  • Suitable for high-end applications like smartphone screens or optical lenses.

2. Stone

Recommended Laser Marking Machine: CO2 Laser Marking Machine

• CO2 Laser Marking Machine:
  • Wavelength of 10.64μm, with good absorption by stone surfaces.
  • Suitable for engraving or marking on stone surfaces, such as text, patterns, or logos.
  • High processing efficiency and low cost.
• Note: Stones are hard materials, so laser power and frequency need to be adjusted for optimal results.

3. Wood

Recommended Laser Marking Machine: CO2 Laser Marking Machine

• CO2 Laser Marking Machine:
  • Wavelength of 10.64μm, perfectly suited for wood's absorption characteristics.
  • Can achieve varying depths of engraving effects on wood surfaces for art pieces, labels, or decorative items.
  • Fast processing speed, suitable for mass production.
• Note: Wood is flammable, so laser power must be controlled to avoid excessive carbonization or burning.

4. Ceramics

Recommended Laser Marking Machine: UV Laser Marking Machine or Fiber Laser Marking Machine (for specially coated ceramics)

• UV Laser Marking Machine:
  • No thermal damage to ceramic surfaces, suitable for fine markings.
  • Commonly used for electronic component housings, tableware, or other precision ceramic products.
• Fiber Laser Marking Machine (for specially coated ceramics):
  • If the ceramic surface has a metallic coating or special treatment, fiber laser marking machines can also achieve good results.
  • Clear and durable markings, suitable for industrial applications.

Notes

1. Test Samples: The actual performance of different materials may vary due to differences in composition. It is recommended to bring real samples to professional manufacturers for testing.
2. Processing Parameters: Adjust laser power, frequency, and speed based on material thickness, hardness, and surface characteristics for optimal results.
3. Equipment Cost: UV lasers and femtosecond lasers have higher equipment costs and are suitable for high-precision needs, while CO2 lasers have lower costs and are suitable for regular processing.
