Synopsis
Laser marking has transformed the way industries approach identification, traceability, and design by offering durability, accuracy, and versatility across a wide range of materials. Unlike traditional methods, laser marking provides permanent, non-contact solutions that ensure high-quality results without compromising the integrity of the substrate. From metals to plastics, glass, and wood, laser marking machines—such as fibre, CO2, and UV lasers—cater to unique application needs. With fibre laser marking excelling in metals, CO2 laser marking delivering solutions for wood and non-metals, and UV laser marking offering unmatched precision for plastics and glass, industries gain tailored results with minimal maintenance. The technology is increasingly used in automotive, electronics, healthcare, and aerospace sectors for part identification, compliance labelling, and decorative finishes. Laser marking integrates seamlessly into production lines, reducing downtime and enhancing productivity. Supported by advanced laser beam delivery systems, supercontinuum white light laser machines, and UV nanosecond lasers, it has become an indispensable part of modern manufacturing. With its efficiency, cost-effectiveness, and adaptability, laser marking stands as a cornerstone of precision-driven production for industries worldwide.

Introduction to Laser Marking
What is Laser Marking?
Laser marking is a non-contact process where a focused laser beam alters the surface properties of a material to create permanent marks. These can include text, barcodes, graphics, and serial numbers.
Types of Laser Marking Technologies
Fibre Laser Marking
Ideal for metals, fibre laser marking machines provide durability and precision, making them suitable for automotive, electronics, and industrial applications.
CO2 Laser Marking
Perfect for wood and non-metal materials, CO2 laser marking ensures high beam quality, making it effective for engraving and cutting applications.
UV Laser Marking
With a short wavelength, UV laser marking is highly effective for plastics and glass, offering fine detail and minimal thermal stress.
Why Laser Marking is Superior to Traditional Methods
Permanent and Non-Contact Process
Unlike inkjet or mechanical engraving, laser marking ensures permanent, clean marks that resist wear, corrosion, and fading.
High Precision and Repeatability
Laser beam micromachining and delivery systems provide micron-level accuracy, enabling consistent, repeatable results.
Applications of Laser Marking Across Industries
-
- Automotive: Part identification and compliance labelling
- Healthcare: Medical device marking for traceability
- Electronics: PCB coding and micro-component identification
- Aerospace: High-durability component marking
- Consumer Products: Branding and decorative finishes

FAQs
What is laser marking used for?
Laser marking is used for creating permanent marks such as barcodes, serial numbers, logos, and decorative designs on materials like metals, plastics, glass, and wood. It is widely applied in automotive, medical, and consumer product sectors.
Which laser marking technology is best for metals?
Fibre laser marking is the preferred choice for metals. It provides durable, precise, and high-speed marking suitable for parts identification and industrial labelling.
Can CO2 lasers be used for industrial marking?
Yes, CO2 lasers are ideal for non-metals such as wood, acrylic, and paper. They provide high-quality engraving and cutting, making them suitable for signage and consumer products.
Why is UV laser marking important for plastics?
UV laser marking is essential for plastics and glass because its short wavelength minimises thermal stress, preventing damage while delivering fine, detailed marks.
What are the advantages of laser marking over inkjet printing?
Laser marking is permanent, requires no consumables, and provides precise, consistent results. Unlike inkjet printing, it does not fade, smear, or wear over time, reducing long-term costs.
Can laser marking machines be integrated into production lines?
Yes, laser marking systems are designed for integration into automated production lines. This ensures continuous operation, reduced downtime, and consistent marking across large volumes.
How effective is laser marking for traceability?
Laser marking is highly effective for traceability. Permanent marks such as QR codes, barcodes, and serial numbers ensure that products can be tracked throughout their lifecycle.
