Polycarbonate Laser Marking
Achieving Superior Clarity and Contrast
Why Polycarbonate?
Achieving High-Contrast Marks
One of the most sought-after outcomes in polycarbonate laser marking is creating marks with exceptional contrast that remain clearly visible under varying lighting conditions and viewing angles.
COâ‚‚ laser systems excel at creating high-contrast marks on polycarbonate through controlled surface modification. The laser energy causes localized melting and foaming of the material surface, creating a white or light-colored mark that provides excellent light-scattering properties.
Clarity Preservation Features
Optical Clarity
Maintaining transparency while creating visible marks is crucial in automotive, aerospace, and electronics where optical properties cannot be compromised.
Surface Marking
Creates frosted or white appearance through microscopic surface texturing that scatters light while leaving bulk material optically clear.
Internal Engraving
Subsurface marking creates marks within the material volume without disrupting either surface, perfect for protective applications.
Precision Control
Advanced laser parameters enable marks that remain highly visible while limiting thermal effects to only marked regions.
Durability
Marks withstand UV radiation, temperature cycling, chemical contact, and mechanical wear while maintaining contrast.
Versatility
Works with clear, colored, UV-stabilized, and flame-retardant polycarbonate grades for diverse applications.
Industry-Specific Applications
Automotive Lighting
Headlights, tail lights, and instrument panels
Polycarbonate has largely replaced glass in automotive headlight lenses and tail light assemblies. Laser marking enables precise placement of required regulatory information without affecting light transmission or creating visual artifacts.
Medical Equipment
Device housings and laboratory instruments
The medical industry extensively uses polycarbonate for device housings, fluid containers, and diagnostic equipment. Laser marking withstands repeated sterilization cycles including autoclaving and chemical disinfection.
Safety Equipment
Protective gear and barriers
Safety glasses, face shields, protective barriers, and riot shields utilize polycarbonate for impact resistance. Laser marking applies certification marks without compromising protective properties.
Consumer Electronics
Smartphones, tablets, and accessories
Smartphone cases, tablet covers, and display windows incorporate laser-marked polycarbonate for brand identification and regulatory markings. Technology enables crisp logo reproduction and detailed graphics.
Material Grade Considerations
UV-Stabilized PC
Outdoor applications benefit from UV-stabilized grades that prevent yellowing. May require parameter adjustment for optimal contrast.
Flame-Retardant PC
Contains brominated or phosphorus-based compounds. Produces distinct mark colors and may require specialized parameters.
Clear Polycarbonate
Produces white or frosted marks with excellent contrast. Ideal for applications requiring transparency and mark visibility.
Colored Grades
Light-colored polycarbonates achieve good contrast with appropriate laser parameters. Dark colors may need higher energy.
