Colour Anodizing Service for Aluminium Parts
Colour Anodizing Service for Aluminium Parts
In-house colour anodizing on a fully automatic line, with batch-level colour verification for appearance-critical assemblies.
Product Overview
Anodizing converts the aluminium surface into a controlled oxide layer rather than applying a coating on top of it, which is why it does not flake or peel. It provides corrosion resistance, wear resistance, colour, and electrical insulation in a single process.
Typical applications
- Heat sinks
- Audio panels
- Consumer electronic housings
- Industrial components

Manufacturing Capability
In-house process chain
Extrusion, die casting, CNC machining, stamping, anodizing, powder coating and laser marking are performed in our own 12,000 m² facility. Fewer handovers means fewer places for schedule and quality to slip.
Tooling under our control
Extrusion dies, die casting moulds and stamping dies are designed and manufactured in our own tool room, which shortens tooling lead time and allows manufacturability issues to be raised before the tool is cut.
Quality system
ISO 9001, ISO 14001 and IATF 16949 certified. Materials are traceable to heat number, gauges are calibrated on a defined cycle, and dimensional reports are available on request.
Built for OEM programs
We manufacture to your drawings and samples. We are not a design house, which means our focus stays on producing your part accurately, repeatedly and at a competitive cost.
Quality Control
How to Order
- Send your requirementDrawing or 3D model, material, quantity and any critical or cosmetic requirements.
- Quotation and DFM feedbackWe quote with a stated validity period and flag any manufacturability or tolerance concerns before you commit.
- SamplingSamples are produced through the normal production process, typically within 3 to 7 days, with dimensional data where required.
- Approval and toolingOn sample approval we finalise tooling. Tooling is designed and manufactured in-house.
- Bulk productionProduction typically runs 45 to 60 days, with progress reported through the run.
- Inspection and shipmentFinal inspection, packing for export, documentation issued and shipment arranged by sea, air or express.
