How To Improve the Quality of Laser Marking

We outline the common laser marking quality key points and tips as follows:

Non-deformation of marking, accuracy location

  • Lens correction with normal accuracy or higher resolution
  • Improved angle of scanning galvanometer, focal length determines accuracy of position

Micro-engraving or forming

  • Adjust pulse-width, or try different wavelength laser sources
  • Add photosensitive chronotropic additives
  • The filling pattern can raise the readability of the mark
  • Surface removal or deep engraving can increase readability of the mark.

Low recognition

  • Use special coding and a corresponding decoding tool
  • Choose a visible angle marking pattern, the image can be observed at a certain angle only.
  • Use an ultra small size marking, can be counterfeited by a customized microscope reader

Improve firmness of the mark

  • Increase engraving depth
  • Increase the peak power of laser source, along with salt spray tests
  • select the right parameters for energy density, along with abrasive paper wear test
  • Post=process reinforcement, for instance, the acid cleaning passivization

Meet special requirements from industry regulation

  • Select high frequency pulsed laser or CW laser to ensure no light leaking through micro-holes in aircraft pilot panels
  • Resolve the limitations of uniformity in workpiece materials
