Laser Marking

Technical papers on laser marking plastics: laser types, laser-sensitive additives, material science and marking for traceability and security.

• MOPA Fibre Lasers for Marking Plastics – All Lasers are Not Created Equal!
  Why MOPA fibre lasers outperform Q-switched designs for plastics: waveform pulse control, beam quality M2 consistency, irradiance and fluence.
• Laser Marking of Glass-Filled Polymers – The Importance of Injection Moulding Operations
  Why injection moulding decides laser mark quality on glass-filled plastics: glass emergence, resin-rich surfaces, fill percentages and marking mechanisms.
• How Do You Mark Plastic With a Laser? Plastic Laser Marking With Laser Additives
  Laser marking nylon and polyamide explained: the three contrast mechanisms, smart additives, MOPA pulse width, and Grade A code verification.
• Laser Marking and Machine Vision Codes for Product Security and Traceability
  Direct part marking with 2D Data Matrix codes: how they compare to barcodes, MIL-STD-130M requirements, and under-hood automotive applications.
• Basic Material Science for Plastics Laser Marking
  The chemistry behind plastics laser marking: how polymers, laser additives and specific wavelengths interact, and when additives are actually required.
• Fibre Lasers: Selection and Additives
  Choosing a fibre laser for marking plastics: fixed-pulse versus MOPA, repetition rate limits, and how additives improve contrast and marking speed.
• Breakthrough Additives Enhance Plastics Laser Marking: Superior Contrast, Line Edge Detail and Speed
  Laser marking additives that deliver superior contrast, line edge detail and up to 25% faster marking on plastics previously difficult to mark.
• “Smart Additives” Enhance Plastics Laser Marking
  How laser marking smart additives achieve contrast, line edge detail and speed on plastics that were previously difficult or impossible to mark.
• FDA-Approved Additives Boost Inline Plastics Laser Marking
  FDA-approved laser additives bring jet-black and light contrast to inline plastics marking, replacing rotary gravure and pad printing at high speed.
• Fibre Laser Marking for Product Security, Identification and Anti-Counterfeiting
  Direct part marking with fibre lasers: Data Matrix versus barcode, MIL-STD-130 traceability, and why laser beats inkjet for machine vision codes.
• Fibre Laser Marking on Nylon (Polyamide) Plastics
  High-contrast laser marking on nylon: polyamide chemistry, smart additives, ytterbium fibre laser selection and the MOPA pulse range that works.
• Fibre Laser Enables Marking of Advanced Plastics
  FDA-approved laser additives and nanosecond ytterbium fibre lasers deliver jet-black and light contrast on clear and opaque polymers, on the fly.
