Aluminum shells, enclosures and small-batch machined parts from 6061, 6063, 7075 and ADC12. We hold ±0.005 mm on tight bores and flatness, then finish with anodizing, blasting or laser marking. One prototype or 10,000 parts.
Most of them are decided before the first cut.
Aluminum cuts fast, so heat builds quickly in a 1.5 mm wall. Release the clamps and the part springs open, and your lid no longer sits flush. The fix is roughing with stock left on, a stress-relief pause, then a light finishing pass. We plan that sequence before the program is posted.
A 7075 shell with M2 threads in a 2 mm boss will strip on the second torque cycle. Either the boss gets thicker, or the thread moves to a steel insert. We flag this at DFM, not after the driver slips.
Type II anodizing adds roughly 5–10 μm per surface. A Ø8 mm pin hole becomes a press fit that no longer accepts the pin. Mask the bore or cut it undersize by the coating thickness. Send us the finish callout with the drawing and both sides match.
On a visible aluminum shell, a single tool mark on the top surface scraps the whole part. We machine cosmetic faces last, with fresh tooling and a finishing allowance, and bead blast before anodizing to blend the grain.
From a single shell to a 10,000-part run, on the same process.
Aluminum housings usually have features on five sides: a pocket on top, ports on the side, a mounting flange underneath. On a 3-axis machine that means three fixtures and three chances to lose your datum. Our 16 simultaneous 5-axis centers cut those faces in one setup, so the bore-to-flange relationship stays inside ±0.005 mm.
For long profiles up to 4,000 mm we use the large-travel machines with a 4,000 × 400 × 150 mm envelope. Small shells run on the compact 500 × 500 × 450 mm centers, where a Ø400 mm rotary table handles the curved sides.
Small-batch aluminum work fails when the prototype and the production run are built differently. We machine the first article on the production machine, with the production fixture and the same tool list. What you approve is what you get at volume.
Setup cost is real, so we keep it in one place. After the first article passes inspection, the run continues on the same setup. There is no minimum order quantity, and a 20-piece run gets the same inspection as a 5,000-piece run.
Pick the alloy before the finish, not after.
| Alloy | Best for | Watch out for |
|---|---|---|
| 6061-T6 | General shells, brackets, housings | Anodizes evenly; weld strength drops |
| 6063 | Extruded-style frames, visible covers | Softer; deep pockets can chatter |
| 7075-T6 | High-strength internal frames | Harder to anodize; threads strip easily |
| 2024 | Fatigue-loaded aerospace parts | Poor corrosion resistance; needs coating |
| 5052 / 5083 | Sheet-metal covers, marine enclosures | Not for heavy machining stock removal |
| ADC12 | Die-cast housings, then finish machined | Porosity shows after anodizing |
One supplier from raw bar to packed part.
16 simultaneous 5-axis centers cut aluminum housings with features on five sides in one setup. Ideal for shells where hole-to-bore alignment matters.
Mill-turn centers produce round aluminum bodies and caps with turned OD, milled flats and drilled ports without re-fixturing.
First-article aluminum prototypes in days, on the same machine and fixture that will run production.
Clear, colour, hardcoat and conductive anodizing; bead blasting, brushing, polishing, powder coating and black oxide.
Serial numbers, logos and control icons on aluminum. Minimum character height is 1.5 mm for a clean, readable mark.
We assemble aluminum shells with inserts, gaskets and hardware, then inspect the finished unit before packing.
Numbers you can put in your own process sheet.

The numbers behind the service.
Fifteen years of cutting aluminum across 3 wholly-owned plants covering 7,600 m², with 150 technicians on the floor.
Not just on the first article. Process monitoring runs through the batch, and 100% of parts are inspected before shipment.
A quotation and free DFM analysis return within 12 hours. Production can begin within 24 hours of approval.
Raw material check, in-process monitoring and final inspection. The rate reflects parts that pass the print on first submission.
No minimum order quantity. A single prototype and a 10,000-part run go through the same setup and inspection.
ISO 9001:2015, IATF 16949:2016, ISO 13485:2016 and ISO 27001:2022 cover quality, automotive, medical and data security.
Sealing faces must be flat and the bolt pattern must line up on the vehicle. We machine the gasket face and dowel holes in one setup.
Visible aluminum shells need a clean front face and consistent anodize color across the batch. Cosmetic faces are cut last with fresh tooling.
Round bodies with concentric bores and milled side ports. Mill-turn centers hold concentricity without moving the part between operations.
Long aluminum profiles up to 4,000 mm with drilled manifolds. Large-travel machines handle the length without repositioning the part.
6061-T6 covers most enclosures and brackets. It machines cleanly, takes anodizing evenly and has enough strength for mounting hardware.
Choose 7075-T6 only when you need higher strength and the part is internal. It is harder to anodize and small threads strip more easily. For visible covers that need a uniform finish, 6063 is a better match.
Type II anodizing builds roughly 5–10 μm per surface, so a Ø8 mm bore can shrink by 10–20 μm in diameter. That is enough to turn a slip fit into a press fit.
Mask the bore, or specify the pre-plate dimension undersize by the coating thickness. Tell us the finish on the drawing and we will set the machining allowance to match.
Yes, with the right sequence. We rough with stock left on, let the part stabilize, then take a light finishing pass. Clamping pressure is controlled so the wall does not deflect under the tool.
Below about 1 mm wall thickness, plan on additional operations and a higher part cost. That is a geometry decision, not a machine limitation.
M2 is practical in 6061 if the boss wall is at least one diameter thick, meaning roughly 2 mm of material around the thread. Smaller than that, the thread pulls out on assembly.
For repeated assembly or higher torque, use a steel insert or move the thread to a thicker section. We flag marginal thread bosses at the DFM stage.
There is no minimum order quantity. A single prototype and a 10,000-part run go through the same setup, the same inspection and the same production machine.
Small batches are not treated as samples. The first article is built on the production setup, so what you approve is what ships at volume.
Cosmetic faces are machined last, with fresh tooling and a finishing allowance. Bead blasting before anodizing blends the tool marks so the grain looks even.
Tell us which faces are visible. If a face is hidden, we can machine it faster and skip the cosmetic steps.
A quotation and free DFM analysis come back within 12 hours. Production can start within 24 hours of approval, and parts typically ship in 3–5 days.
That applies to standard aluminum work. Complex 5-axis shells with tight cosmetic requirements may need more time, and we will say so in the quote.
Uploads are secure and confidential, and we sign an NDA on request before reviewing your files. Our ISO 27001:2022 certification covers how we handle customer data.
If you prefer, send a simplified model for quoting and release the full drawing after the NDA is signed.
Upload a STEP file or PDF. We return a price, a lead time and DFM notes on thin walls, threads and anodizing allowances. No minimum order quantity, and 100% inspection before shipment.
