One-off parts and pilot runs cut on 127 CNC machines in Dongguan. Tight tolerances, real DFM feedback, and inspection reports you can hand to your own customer.
You send a STEP file on Monday and hear nothing until Friday. The design review slips a week, and the tooling decision that depends on it slips with it. We return a quotation and a DFM analysis within 12 hours, so you can approve or change the geometry while the schedule still has room.
The first article measures fine, then the second and third drift. Bores that should be round come out tapered, and hole positions walk. That usually means the setup was never stable, or the fixture was improvised. We hold ±0.005 mm on production runs by cutting on rigid 5-axis centers and checking in-process, not only at the end.
A prototype that fits but scratches white or shows tool marks will not survive a design review or a trade show. Sending it out for anodizing adds another week and another freight risk. We run anodizing, bead blasting, brushing, laser marking and plating in-house, so the part leaves one facility and arrives ready to show.
When the parts arrive with no dimensional report, you cannot tell whether a failed test came from the design or the machining. Material certificates and inspection reports are available on request, covering raw material check, in-process monitoring and final inspection.
Machining decisions that keep a prototype close to the drawing, and to the production part that follows it.
A prototype often has features on five faces: angled ports, undercuts, thin ribs, a boss that sits behind another wall. Each extra setup adds a datum shift and a chance for error. With 16 simultaneous 5-axis machining centers, we cut those features in one or two setups instead of five.
We also run 12 four-axis mills, 27 three-axis machines and 16 mill-turn centers. Maximum processing size is 4,000 mm, with travels of 4,000 × 400 × 150 mm and 750 × 1,150 × 550 mm on the larger platforms. Shafts, housings and long brackets all stay on one machine.
A prototype only tells the truth if it is made from the same material as the production part. We machine aluminium 6061, 6061-T6, 7075, 2024, 5052 and ADC12; stainless 303, 304, 316L, 17-4PH and 440C; steels including 4130, 4140 and 4340; copper and brass C110 and C36000; titanium TC4 (Ti-6Al-4V); and plastics from ABS and POM through PEEK and HDPE.
Surface finish is set to what the part has to do. Sealing faces and bearing bores go to Ra 0.2–0.8 μm. General machined surfaces sit at Ra 0.8–1.6 μm or Ra 1.6–3.2 μm as machined. Anodizing, plating, powder coating and laser marking run in the same facility, with a minimum character height of 1.5 mm for engraving.
Use this to decide before you commit a design to tooling.
| Situation | Better fit | Why |
|---|---|---|
| Tight tolerance, functional test | CNC machining | Holds ±0.005 mm and real material properties |
| Wall under 1.5 mm, complex inner channels | 3D printing | Machining may deflect or need split parts |
| 50 to 500 parts, one geometry | CNC or vacuum casting | Machining avoids tooling cost at low volume |
| Over 10,000 identical parts | Die casting | Tooling cost pays back at higher volume |
| Large flat panels, simple bends | Sheet metal | Faster and cheaper than milling from solid |
| Transparent or optical part | CNC on PMMA or PC | Polished edges stay clear without layer lines |
Simultaneous 5-axis work for angled faces, deep pockets and contoured surfaces in one setup.
Prismatic parts, plates and brackets where indexed or three-axis work is enough.
Mill-turn centers for shafts, fittings and parts that need turning and milling on one machine.
One-off parts and small batches, with DFM feedback before the first cut.
Enclosures, brackets and printed parts for early form checks alongside machined prototypes.
Anodizing, plating, powder coating, bead blasting, polishing and laser marking in-house.
Numbers here are the ones we work to, not estimates.

Three wholly-owned plants and 7,600 m² of manufacturing space in Dongguan, plus a factory in Singapore at No.3 Joo Koon Circle.
16 simultaneous 5-axis centers, 12 four-axis mills, 27 three-axis machines and 16 mill-turn centers under one roof.
Tolerance held to ±0.005 mm, with a qualification rate of 99.99% across shipped parts.
Raw material check, in-process monitoring and final inspection. Reports on request.
ISO 9001:2015, IATF 16949:2016, ISO 13485:2016 and ISO 27001:2022.
Measured across past orders, with shipping in 3–5 days on standard prototype work.
Material certificates and dimensional reports travel with the parts.
Thin walls, connector cutouts and anodized finish on one order.
Cosmetic surfaces finished so the part can go straight to a design review.
The same program scales from one part to a few hundred when the design freezes.
STEP and IGES cover most work. For turned parts, a 2D PDF with dimensions helps us confirm what matters. Native SolidWorks, Fusion and Inventor files are fine too.
Send the assembly if fits and clearances matter. We check the mating part before cutting, not after.
Yes, when the feature and material allow it. A 0.5 mm wall in PEEK behaves differently from a 20 mm steel bore, so we will tell you which dimensions are realistic on the first part.
We check in-process rather than only at the end. That way a drifting setup is caught while the part is still in the machine.
No. We machine single prototypes and run batches over 10,000 parts. The setup cost is the same whether you order one or twenty, so ordering spares with the first part is often cheaper than a second run later.
Quotation and DFM analysis come back within 12 hours. Production can start within 24 hours once the drawing and material are confirmed, and parts ship in 3–5 days.
If a feature needs a fixture or a special cutter, we tell you at quote stage so the date is real.
We stock or source aluminium 6061, 7075 and 2024, stainless 303, 304 and 17-4PH, steels 4130 and 4140, titanium TC4, brass C36000, and plastics including POM, PC, PEEK and HDPE.
If your specification names an alloy we do not list, tell us what property matters and we will suggest the closest equivalent.
Uploads are secure and confidential. We sign an NDA on request before files change hands, and we hold ISO 27001:2022 for information security.
Files are used for your order only. We do not reuse customer geometry in other projects.
Every order gets a raw material check, in-process monitoring and final inspection before shipment. Dimensional reports and material certificates are available on request.
If your customer needs first article inspection to a specific format, say so at quote stage and we will work to that format.
Hollow parts with internal channels or lattice structures are usually better printed. Very thin walls in soft plastic can deflect under cutting force.
If you need hundreds of identical parts in a rubber-like material, vacuum casting or 3D printing may cost less than machining. We will say so rather than take the order.
Upload your drawings and we will come back with pricing, lead time and the features we would change before cutting.
