Upload a STEP file and we machine your prototype from solid stock, not a print. DFM feedback within 12 hours, production starts within 24 hours, and parts ship in 3–5 days. One part or 10,000, no minimum order quantity.
A supplier who quotes without reading the GD&T will machine to a number you never asked for. You find out at assembly, and the fix costs another two weeks. We return a quotation and a free DFM analysis within 12 hours, tolerance callouts included.
Many shops set a minimum order quantity that a single bracket cannot meet. You end up paying for parts you will never use. We run from one prototype to 10,000+ part runs, so a single piece is a normal order here.
Hand-finished first articles hide a process that cannot repeat. When the pilot run arrives, hole positions drift and wall thickness changes. We inspect 100% before shipment and keep raw material, in-process and final records for every lot.
You send a revision and hear nothing for three days. The toolpath was already cut. We confirm the drawing revision before the spindle turns, and production can start within 24 hours of a released CAD file.
One engineer owns your part from DFM to final inspection.
A prototype only tells you the truth if it is made the way the production part will be made. We machine your design from solid billet on 127 high-precision CNC machines, including 16 simultaneous 5-axis centers, 12 four-axis mills and 16 mill-turn centers. Maximum processing size is 4,000 mm, so large housings and long frames do not need to be split.
Tolerance holds at ±0.005 mm (±0.0002 in) on critical features. As-machined surfaces sit at Ra 1.6–3.2 μm, and we can take functional sealing faces down to Ra 0.2–0.8 μm when the drawing calls for it.
Prototyping in a substitute material is a common way to lose a month. If the housing will be 6061-T6, machine it in 6061-T6. We stock aluminium 6061, 2024, 5052, 5083, 6082, 7075 and ADC12; stainless 303, 304, 316L, 17-4PH and 440C; steel 1018, 1045, 4130, 4140 and 4340; plus copper, brass, titanium TA2 and TC4, Inconel, magnesium and engineering plastics from POM and PEEK to HDPE and carbon fibre.
Finishing decides whether the prototype survives a trade show or a fit check. Anodizing, electroless nickel, zinc and silver plating, powder coating, black oxide, bead blasting, brushing and polishing are all available in house or through our qualified partners. Laser marking goes down to 1.5 mm character height for serials and logos.
Three routes we quote most often for prototype work.
| Route | Best fit | Watch out for |
|---|---|---|
| 3-axis milling | Flat plates, brackets, open pockets | Deep cavities need long reach tooling |
| 5-axis milling | Angled faces, contoured ducts, undercuts | Higher setup cost on very simple parts |
| Mill-turn | Shafts, bushings, threaded fittings | Off-axis holes still need a second op |
3-axis, 4-axis and 5-axis milling plus mill-turn. Metals and plastics, from a single piece to 10,000+ part runs.
Functional prototypes machined from production-intent material so fit, weight and strength match the real part.
Bent, punched and welded enclosures, brackets and chassis for prototype builds and pilot runs.
SLA and SLS for early form checks when a machined surface is not yet needed.
Small batches of urethane parts for pre-production testing and market samples.
Anodizing, plating, powder coating, blasting, polishing and laser marking.
The same checklist applies whether you order one part or a thousand.

Fifteen years on prototype and production work, three wholly-owned plants, 7,600 m² of manufacturing space and 150 technicians in Dongguan plus a Singapore factory.
±0.005 mm, or ±0.0002 in. We tell you up front when a feature needs a different process to hold it.
Quotation and free DFM analysis back within 12 hours. Production can start within 24 hours of drawing release.
Raw material check, in-process monitoring and final inspection on every lot. Dimensional reports on request.
ISO 9001:2015, IATF 16949:2016, ISO 13485:2016 and ISO 27001:2022.
One part is a valid order. The same program scales to 10,000+ part runs without a process change.
Fixture and trim parts that must fit the first time.
Joint housings and brackets where weight and stiffness both matter.
Large frames and manifolds up to 4,000 mm.
Housings and instrument parts with documented inspection.
Quotation and free DFM analysis come back within 12 hours of your CAD upload. Production can start within 24 hours of a released drawing, and parts normally ship in 3–5 days.
Complex 5-axis parts or orders that need plating and anodizing add time, and we tell you the realistic date in the quote rather than after the order.
No. One prototype is a normal order, and the same program runs to 10,000+ parts without changing process or supplier.
Unit cost drops as volume rises because setup is amortized, but we do not force a batch size on you to get the work.
±0.005 mm (±0.0002 in) on critical features, measured with calibrated instruments and reported on request.
Some features cannot hold that in one setup. Deep small holes, thin unsupported walls and long slender shafts are the usual cases, and we flag them during DFM instead of letting them fail at inspection.
STEP and IGES for 3D geometry, plus a 2D PDF drawing with GD&T, datum callouts and finish requirements.
A model alone does not define tolerance, thread class or surface finish. Sending both cuts one round of questions and usually saves a day.
Yes. Aluminium 6061-T6, 7075, 6082 and ADC12, stainless 304, 316L and 17-4PH, steel 4140 and 4340, titanium TC4, Inconel and engineering plastics including POM, PEEK and HDPE are all standard.
Prototyping in a substitute material changes stiffness and thermal behavior. If the test is functional, machine the production alloy.
Uploads are secure and confidential, and we sign an NDA on request before any file is opened.
We do not share customer drawings, part photos or project details with other clients, and access inside the plant is limited to the engineers on your job.
Send dimensional data and photos, and we compare them against the drawing and inspection record to find whether the deviation is in the part or in the design intent.
If we machined outside the drawing, we remake the parts. If the drawing itself needs a change, we quote the revision and start within 24 hours of release.
Yes. The same machines, fixtures and inspection plan carry over, which removes the re-qualification step that a supplier switch usually adds.
Typical bridge volumes run from a few dozen to several thousand parts before tooling makes sense for die casting or injection molding.
