LASER MARKING

PERMANENT LASER MARKING FOR METAL & PLASTIC PARTS

Our 60W fibre laser delivers high-contrast, permanent marking on metal and plastic components — ideal for part identification, branding, and traceability.

We can mark logos, serial numbers, batch data, and other information directly onto your parts with exceptional precision and durability. Laser marking is non-contact and can be done before or after surface treatments like anodising, plating, or coating.

Whether you're personalising a one-off item or serialising a production run, laser marking ensures professional results with minimal lead time.

COMMON APPLICATIONS FOR LASER MARKING

We regularly laser mark parts for a wide range of industries, including:

Engineering & Manufacturing part numbers, batch codes, QR/data matrix codes

Electronics branding on enclosures, terminal ID, PCB serialisation

Automotive & Motorsport VIN plates, performance components, compliance info

Medical & Pharmaceutical instrument tracking, UDI marking, cleanroom-safe

Aerospace traceability codes, alloy ID, anti-tamper markings

Consumer Products logos, product branding, custom messages

Lighting logo etching on housings, driver units, and fittings

Laser marking is ideal for aluminium, stainless steel, titanium, brass, and many plastics.

FREQUENTLY ASKED QUESTIONS

  • Laser marking (also called laser etching or engraving) is a precise, permanent method of adding text, logos, or serial numbers to metal and plastic parts. It’s done using a high-powered fibre laser that alters the surface without physical contact or cutting.

  • We laser mark a wide range of metals (including aluminium, stainless steel, brass, and titanium) and selected plastics. It’s ideal for anodised parts, coated metals, and industrial-grade plastics.

  • We work from vector files (AI, DXF, SVG, PDF) for logos and layouts, or can help convert your artwork. For basic markings like text or serial numbers, just send us your part details — we’ll handle the rest.

  • Yes. Laser marking is permanent, abrasion-resistant, and does not wear off. It’s suitable for long-life applications, harsh environments, and compliance with traceability standards.

  • Yes — our 60W fibre laser can mark on anodised aluminium, powder-coated metal, and plated finishes without damaging the protective layer.

  • Yes — laser marking is ideal for prototypes, one-off parts, and low-volume production. We can apply variable data such as unique serial numbers, barcodes, QR codes, and batch information directly onto your parts. It’s a fast, cost-effective way to add permanent identification and improve traceability without any tooling or setup required.

AS FEATURED BY LOTUS LASER SYSTEMS

We were recently visited by Lotus Laser Systems to showcase the installation of our new fibre laser — and they gave a full look inside our machine shop too. The video covers how we use laser marking alongside CNC machining, prototyping, and product development to deliver high-precision parts for UK manufacturers.
