Laser Marking Polyimide Films: Kapton, Flexible Circuits and High-Temperature Electronics
Polyimide film carries identification on flexible circuits and high-temperature electronics. Why UV sources dominate, and what thin-film marking demands.
Laser Marking Polystyrene and HIPS: Packaging, Appliances and Disposables
Polystyrene marks readily and distorts just as readily. Why the process window is narrow, how HIPS differs, and what to control on thin-walled parts.
Laser Marking PC-ABS and ASA: Blends in Automotive and Appliance Parts
PC-ABS and ASA dominate automotive interiors and appliance housings. How blend ratio changes marking behaviour, and why each grade needs its own qualification.
Laser Marking on Textured and Matte Moulded Surfaces
Texture changes how a laser mark reads without changing the mark itself. Why grained surfaces lose contrast, and how to specify and measure marks on them.
Laser Cutting Plastics: How It Differs from Engraving and When Each One Wins
Cutting and engraving use the same machine and behave very differently. Which polymers cut cleanly, how to control edge quality, and what must never be cut.
How Colourants and Pigments Change Laser Marking Results
The colourant is often the most influential ingredient in a laser marking result. How pigments absorb, bleach and shift, and why each colour needs its own recipe.
Laser Marking Glass- and Mineral-Filled Plastics: What Changes When Filler Is Added
Filler changes laser marking more than most people expect, and usually for the better. How glass and mineral loading affect contrast, and how to control fibre emergence.
Color Laser Marking on Plastics: How Contrast and Color Are Achieved with Additives
How dark, light and true colour laser marks are produced on plastics through additive chemistry, and the process variables that control the result.
Laser Marking of Polycarbonate: Techniques, Parameters, and Industry Applications
Polycarbonate marks well thanks to its aromatic backbone. Learn the laser types, additives, parameters and stress-crazing risks for reliable PC marking.
