Fibre Laser Marking Services

Precision. Permanence. Traceability.

Welcome to the National Engravers Fibre Laser Marking department. As a leading UK provider of industrial identification solutions, we offer high-speed, high-precision laser marking for a vast array of metallic and composite materials.

Fibre laser technology is the gold standard for industries requiring permanent traceability that can withstand the harshest environments. From aerospace-grade titanium to medical-grade stainless steel, our Kent-based facility is equipped to handle both bespoke prototypes and high-volume industrial production runs.

Our Marking Capabilities

Our state-of-the-art fibre laser systems allow us to achieve a variety of finishes and marks tailored to your specific technical requirements:

• Surface Etching: Creating high-contrast marks without deep penetration.

• Deep Engraving: For parts subject to heavy wear or post-production coatings.

• Annealing: Perfect for medical devices, creating a permanent mark without compromising the surface integrity or corrosion resistance of the metal.

• Ablation: Removing surface coatings (such as paint or anodisation) to reveal the material beneath.

Industries We Serve

We provide specialist marking services to a diverse range of British sectors:

• Automotive: VIN plates, engine components, and gear identification.

• Aerospace: Part numbering and serialisation for safety-critical components.

• Medical: UDI (Unique Device Identification) marking for surgical instruments.

• Defence: Asset tracking and secure identification for military hardware.

• Electronics: Marking heat sinks, enclosures, and delicate circuit components.

Why Choose National Engravers?

With decades of experience in the engraving industry, we understand the importance of accuracy and lead times. We work closely with engineers and procurement managers to ensure every mark meets the required British and International standards.

• ISO Quality Standards: Consistency across every single part.

• Rapid Turnaround: Efficient UK-based production.

• Technical Support: Expert advice on material compatibility and mark types.

Technical Specifications: Fibre Laser Marking

For projects requiring the highest level of detail and speed, we utilise the xTool F2 Ultra system. This professional-grade MOPA (Master Oscillator Power Amplifier) fibre laser allows for greater control over pulse frequency, enabling us to achieve diverse finishes—including colour marking on stainless steel.¹

Supported File Formats

To ensure a seamless transition from your design to the finished product, we accept a wide variety of industry-standard files:

• Vector Files (Recommended): .SVG, .DXF, .AI, .PDF

• Image Files: .PNG, .JPG, .BMP, .TIFF

Why MOPA Technology Matters?

Unlike standard Q-switched lasers, our MOPA Fibre Laser allows us to adjust the pulse duration.² This is critical for:

1. High-Contrast Plastic Marking: Prevents burning or melting of delicate polymers.³

    

2. Colour Marking: Creating vibrant, permanent colours on Stainless Steel and Titanium without the use of inks or chemicals.

3. True Black on Aluminium: Achieving a deep, matte black finish that is highly legible and professional.⁴
