We machine aluminum from one prototype to 10,000+ parts. 16 simultaneous 5-axis centers hold ±0.005 mm, and the shop cuts 6061, 6082, 7075 and ADC12 without moving your job between vendors.
Most of these appear after the first article, not before. That is the expensive part.
Thin aluminum ribs deflect under light clamping. If the first article passes and the batch does not, the fixture was wrong, not the toolpath. We measure thin-wall sections before quoting and pick the clamping method around them.
Anodize, black oxide and laser marking done off-site add a week and a second set of handling marks. We keep finishing and marking in the same flow as the machining so cosmetic surfaces are not re-touched between vendors.
Every extra setup adds datum shift and queue time. On a four-axis part that only needs three faces, we machine to size in one or two operations and hold the datum the drawing actually calls out.
6061 and 6082 look the same on a quote and behave differently after anodizing. 7075 machines clean but cracks at sharp internal corners. We flag the alloy and temper in the DFM review, before the first chip is cut.
Machining, finishing, inspection and shipping stay under one roof in Dongguan.
Aluminum cuts fast, so the setup is usually the bottleneck, not the spindle. Our 16 simultaneous 5-axis centers reach undercuts, angled bosses and deep pockets in one operation. Fewer setups means fewer datum shifts and a shorter queue.
For long extrusions and frame rails we run up to 4,000 × 400 × 150 mm of travel. Smaller parts go on a Ø400 mm rotary table when the geometry needs continuous indexing rather than simple 3+2 positioning.
Aluminum moves with heat and relaxes after roughing. We rough, let the part stabilize, then finish to ±0.005 mm where the drawing needs it. Surfaces that only need a machined look stay at Ra 1.6–3.2 μm, which costs less.
Inspection runs at three points: incoming bar stock, in-process checks at each operation, and a final dimensional check before packing. Reports are available on request. We inspect 100% of parts before shipment, not a sample lot.
Pick the alloy before the toolpath. Finishing and strength follow from it.
| Alloy | Best for | Watch out for |
|---|---|---|
| 6061-T6 | General machined parts, brackets, housings | Anodize color shifts between lots |
| 6082-T6 | Structural parts needing better corrosion resistance | Slightly gummier to tap than 6061 |
| 7075-T6 | High-strength aerospace and tooling parts | Cracks at sharp internal corners |
| 2024-T4 | Fatigue-loaded aircraft components | Poor corrosion resistance without coating |
| 6063-T5 | Extruded frames and enclosures | Lower strength than 6061 |
| ADC12 | Die-cast housings finished by CNC | Porosity can show after machining |
Machining is the core. The rest keeps your part moving without a second supplier.
Complex geometry, undercuts and angled faces in one setup. Suited to joints, housings and brackets with tight position tolerances.
Prismatic parts, plates and frames. Faster and cheaper than 5-axis when the part has clear top and side access.
Shafts, bushings, threaded fittings and parts that need milling on a turned body. 16 mill-turn centers handle both in one cycle.
First articles and design iterations before tooling. Same machines as production, so the prototype predicts the batch.
Anodizing, black oxide, plating, bead blasting and laser marking. Marking holds a minimum character height of 1.5 mm.
Chassis, enclosures and die-cast housings that get CNC finishing passes on mating faces and bores.
Match the part envelope to the machine before you send the file.
| Machine group | Travel or size | Typical parts |
|---|---|---|
| 5-axis centers (16) | 750 × 1,150 × 550 mm | Joints, impellers, angled housings |
| Large 5-axis | 4,000 × 400 × 150 mm | Frame rails, long extrusions |
| Mill-turn (16) | Ø400 mm rotary table | Shafts, fittings, milled round parts |
| 3-axis (27) | 600 × 600 × 600 mm | Plates, brackets, simple pockets |
| 4-axis mills (12) | 500 × 500 × 450 mm | Parts needing four-face access |

Fifteen years in Dongguan, three plants, and a production floor built around aluminum.
Three wholly-owned plants and 7,600 m² of floor space. The same team quotes, programs and inspects your job.
16 five-axis, 12 four-axis, 27 three-axis and 16 mill-turn centers. Capacity for prototypes and 10,000-part runs.
Rough, stabilize, finish. We inspect 100% of parts before shipment and can send reports on request.
Quotation and free DFM analysis within 12 hours. Production can start within 24 hours of approval.
One prototype or 10,000+ parts. No tooling charge on CNC work, so small runs stay viable.
ISO 9001:2015, IATF 16949:2016, ISO 13485:2016 and ISO 27001:2022. NDA available on request.
Housings, brackets and cooling plates. Sealing faces finished to Ra 0.8–1.6 μm and inspected 100% before shipment.
Chassis and heat-sink bodies machined from 6061, then anodized and laser marked in the same flow. Marking characters stay at 1.5 mm or larger.
Arm segments and joint bodies cut on 5-axis centers so bore alignment survives the transfer from prototype to production.
We cut 6061, 6061-T6, 2024, 5052, 5083, 6063, 6082, 7075 and ADC12. If your drawing calls for a temper we do not stock, tell us in the RFQ and we will confirm before quoting.
For most brackets and housings, 6061-T6 is the default. Move to 7075 only when you need the strength, because it machines brittle and corners need radii.
±0.005 mm on critical features, after roughing and stabilization. Aluminum relaxes after material removal, so finishing a part straight off the rough pass is how tolerances drift.
General features can sit looser. Specifying ±0.005 mm everywhere raises cost without improving function.
Yes. There is no minimum order quantity. Prototypes run on the same machines as production, so the first article predicts how the batch behaves.
When volume climbs, we review whether a fixture change or a different machine group shortens cycle time.
Thin ribs deflect under clamping pressure. We choose the workholding around the wall thickness rather than the other way round, and we schedule finishing passes so cosmetic faces are not re-clamped.
If your part is visible after assembly, say so in the RFQ. That changes how we plan the last operation.
Anodizing, black oxide, plating, bead blasting, brushing, polishing and laser marking all run through our finishing line. Keeping it in-house avoids a second set of handling marks.
Laser marking holds a minimum character height of 1.5 mm. Smaller text will not read cleanly.
A STEP or IGES file plus a 2D drawing with tolerances and finish callouts. Material and quantity help. If the drawing is missing critical tolerances, we flag it in the DFM review.
Quotation and free DFM analysis come back within 12 hours. Production can start within 24 hours of approval.
Uploads are secure and confidential. We sign an NDA on request, and we hold ISO 27001:2022 for information security.
Files stay with the quoting and programming team. They are not shared outside the job.
If the part is a thin-shell housing with no tight features and volume is above roughly 5,000 pieces, die casting usually wins on cost. We machine castings on mating faces and bores when that is the better route.
For simple flat plates in high volume, sheet metal with a secondary machining pass can be cheaper than cutting from solid.
Quotation and free DFM analysis within 12 hours. No minimum order quantity, from one prototype to a 10,000-part run.
