Permanent part identity

Raw, anodised and coated aluminium
Aluminium laser marking machines
Create permanent serial numbers, logos, QR codes and DataMatrix symbols on aluminium parts using a process proven on the exact alloy and surface finish.
Material and finish first
The words ‘aluminium part’ do not define one laser process.
Short answer
A fibre laser can permanently mark many aluminium alloys and finishes, including anodised aluminium. The most reliable route is to test the production alloy, colour and coating because a result proven on one finish cannot safely be assumed for another.
Raw, machined, anodised, bead-blasted, painted and powder-coated aluminium can respond differently to the same settings. Oxford Traceability uses representative samples to establish contrast, edge quality, cycle time and acceptable surface change before the machine is specified.

Finish-aware process

Production-ready data
Generate fixed or variable content from recipes, files, scanners or factory systems.
Aluminium surfaces
Define the appearance you need before choosing the source.
Some applications require a bright mark on a dark anodised finish; others need a dark, high-contrast result on a pale surface or controlled removal of paint. The acceptable visual effect, durability and smallest feature are more useful specification inputs than wattage alone.
- Raw and machined aluminium alloys
- Coloured and natural anodised finishes
- Painted and powder-coated housings
- Cast, bead-blasted and brushed surfaces
- Small text, logos, serials and 2D codes
APPLICATION CHECKSend normal production parts.
Include the alloy where known, approved colour range, finish variation, cleaning method and the smallest acceptable code or character.
Fixture and focus
Repeatable presentation protects mark position and code quality.
Part location, focus height and orientation determine whether the approved sample result can be repeated in production. A dedicated nest, adjustable fixture or rotary unit may be required, with sensing or vision to prevent the wrong part or program being used.
- Dedicated and change-part nests
- Part-present and orientation checks
- Focus-height control
- Rotary marking on cylindrical aluminium
- Post-mark vision inspection
APPLICATION CHECKProve the whole process.
A good laboratory mark is only the start. Loading, recipe selection, focus, extraction and inspection need to work at the required production rate.

We will test your parts and help convert the required result into a practical machine specification.
Call 01865 36278501Can a fibre laser mark anodised aluminium?+
Yes, anodised aluminium is a common fibre-laser application. The exact result depends on anodise colour, thickness, alloy and finish, so representative production parts should be trialled.
02Will the mark be black or white?+
The visible result depends on the material and process response. Define the required contrast and supply the actual part so settings can be chosen against an accepted sample rather than a generic colour promise.
03Can the machine mark aluminium housings automatically?+
Yes. A system can be integrated with conveyors, robots, PLCs, product recipes and vision checks where the loading method and line controls are defined.
04Can one machine mark several aluminium products?+
Often yes. Saved programs and change-part fixtures can support a product family, provided every part remains within the working field, focus range and enclosure envelope.
