Custom work from one prototype to 10,000+ piece runs. Metals and plastics, ±0.005 mm tolerance, DFM feedback in 12 hours, and a 100% inspection report with every order.
None of these are exotic. They come from a quote accepted without anyone checking the process.
A drawing calls for ±0.005 mm across a 300 mm aluminium plate and the shop quotes it anyway. First articles come back 0.03 mm out. Now you are reworking a batch or scrapping it, and the schedule has already moved.
A 0.8 mm wall on a PEEK housing looks fine on screen. Clamp pressure and tool deflection push it to 0.5 mm in the middle. The seal no longer seats and the whole housing is scrap.
Your drawing uses A-B-C datums. The shop fixtures off a convenient boss instead. Every hole is in the right place relative to that boss and nowhere near where the mating plate expects them.
You need Ra 0.8–1.6 μm on a sliding surface. The quote says as-machined. The parts arrive at Ra 3.2 μm, the seal leaks at pressure test, and there is no time left to re-machine.
Four steps, one engineer owning the part from RFQ to shipping carton.
Every RFQ gets a free DFM review, returned with the quotation inside 12 hours. Our engineers mark the features that will fight the process: deep pockets with a small corner radius, tolerances tighter than the machine can hold over that length, holes that need a five-axis approach instead of three setups.
You get a written note on what to change and what it saves. Sometimes nothing needs changing. When it does, you find out before the chips fly, not after.
We have 16 simultaneous 5-axis machining centers, 12 four-axis mills, 27 three-axis machines and 16 mill-turn centers. The choice is driven by the part, not by what is free. An impeller or a housing with features on five faces runs on a 5-axis center in one setup. A simple bracket runs on a three-axis mill and costs less.
Mill-turn centers handle parts that would otherwise need two fixtures and a re-datum between operations. That is where concentricity holds. Maximum processing size is 4,000 mm, with travels up to 4,000 × 400 × 150 mm for long parts and Ø400 mm rotary tables for round work.
Pick the route by feature count, tolerance and quantity, not by habit.
| Geometry | Recommended route | Why |
|---|---|---|
| Prismatic, 1–2 faces | 3-axis mill | Lowest setup cost, tolerance holds easily |
| Features on 3–5 faces | 5-axis center | One setup, no datum transfer |
| Turned with cross holes | Mill-turn center | Concentricity kept across features |
| Thin walls under 1 mm | 5-axis, light finishing pass | Less clamp pressure, less deflection |
| Prototype, 1–50 pieces | 3-axis or 5-axis, no tooling | No hard fixture cost to recover |
| 10,000+ pieces | Mill-turn or dedicated fixture | Cycle time dominates the piece price |
One purchase order can cover machining, finishing and inspection.
Complex housings and impellers cut in one setup. Sixteen simultaneous 5-axis centers hold position across five faces without re-datuming.
Prismatic parts on mills, round parts on lathes and mill-turn centers. Tolerances to ±0.005 mm on the features that matter.
First articles before you commit to a fixture. Useful when the fit is still being proven and the design may move twice more.
Anodizing, plating, powder coating, black oxide, bead blasting and laser marking. Minimum character height 1.5 mm on engraving.
Enclosures and brackets when a machined housing would be overkill. Same inspection route as the machined parts.
For volume housings and bridge tooling where machining alone would be too slow or too expensive per piece.
Materials, finishes and inspection are quoted together, not as add-ons discovered later.

| Stainless | 303, 304, 316, 316L, 420, 430, 431, 440C, 17-4PH | 17-4PH when strength and corrosion both matter |

| Titanium & special | TA1, TA2, TC4 (Ti-6Al-4V), Inconel, Mg AZ31B / AZ91D | Inconel needs slower feeds and longer lead time |
| Plastics | ABS, PC, PMMA, POM, PA, PEEK, PP, HDPE, carbon fibre | PEEK and carbon fibre for high temperature |
| Tolerance | ±0.005 mm (±0.0002 in) | Hold on critical features, not the whole part |
| Finish | Ra 0.2–0.8 μm fine, Ra 0.8–1.6 μm high, Ra 1.6–3.2 μm as-machined | State the finish on the drawing |
| Inspection | 100% before shipment, reports on request | Raw material, in-process, final |
The numbers that decide whether your order ships on time and to print.
Three wholly-owned plants and 7,600 m² of manufacturing space in Dongguan, plus a factory in Singapore. The same process travels between sites.
0.005 mm, or ±0.0002 in. We say no when a feature cannot hold it, rather than discovering that on first article.
Across shipped orders. Raw material check, in-process monitoring and final inspection run on every batch.
DFM, fixture design, programming and inspection sit in the same building. No handoff to a third party for the tricky features.
Under 2%. Production can start within 24 hours of drawing release, and parts typically ship in 3–5 days.
No minimum order quantity. A single prototype gets the same inspection route as a production run. NDA available on request.
Traceable material and documented inspection on every lot.
Process control that survives an audit, not just a good first batch.
Cleanable surfaces, tight bores and full documentation.
Repeatable geometry across a 10,000 piece run, same fixture, same program.
±0.005 mm, or ±0.0002 in, on critical features. That number depends on the feature, not the whole drawing. A 5 mm bore in aluminium holds it easily. A 300 mm long bore in 316 stainless is a different conversation because of thermal movement and tool deflection.
Send the drawing and we will tell you which features hold at ±0.005 mm, which need a looser callout, and what the fixture has to look like to get there. Better to have that discussion before the quote than after the first article.
No. We run from one prototype to 10,000+ piece runs. A single part goes through the same raw material check, in-process monitoring and final inspection as a production batch.
For low quantities we program and cut without a hard fixture where the geometry allows it, so you are not paying for tooling you may never use again. Above roughly 500 pieces a dedicated fixture usually pays for itself in cycle time.
Quotation and free DFM analysis come back within 12 hours. Once you release the drawing, production can start within 24 hours, and machined parts typically ship in 3–5 days.
That window assumes the material is standard stock. Inconel, titanium and some engineering plastics need to be ordered in, which adds time. We state that up front in the quote so you can plan the build.
Yes, though we will ask for the critical dimensions in writing. A STEP file gives us geometry; it does not tell us which surfaces seal, which bores take a bearing, or where the mating datum sits.
If you send only the model, we mark the features we assume are critical and send that list back with the DFM note. You confirm or correct it before we cut. That step prevents a part that is geometrically perfect and functionally wrong.
State the finish on the drawing per surface. We work to Ra 0.2–0.8 μm for fine finishes, Ra 0.8–1.6 μm for standard high finish, and Ra 1.6–3.2 μm as-machined.
Finishing operations are not free, so an unspecified surface usually comes back as-machined. Sliding surfaces, seals and optical mounts should always carry a callout. Anodizing, plating, powder coating, black oxide, bead blasting and laser marking are available on the same order.
Every order ships after 100% inspection, and a standard inspection report is included. That covers raw material verification, in-process monitoring and final inspection.
Additional reports and certifications are available on request. Say which ones you need at the RFQ stage, because some require extra measurement time and that affects the schedule.
Yes. Uploads are kept secure and confidential, and an NDA is available on request before you send anything. For aerospace, medical and automotive work this is usually the first document exchanged.
We hold ISO 27001:2022 for information security, alongside ISO 9001:2015, IATF 16949:2016 and ISO 13485:2016.
Aluminium 6061-T6 for housings and brackets, 7075 when the part carries load. Stainless 303 and 304 for general work, 316L and 17-4PH where corrosion or strength matters. Steel 4140 for shafts, POM and PEEK for insulating and high-temperature parts.
Titanium TC4, Inconel and magnesium are available but change the cutting strategy. Inconel in particular runs slower and needs more tool changes, so lead time extends.
