Upload a STEP file. We quote in 12 hours with free DFM feedback. Then we cut your parts on 127 machines in Dongguan, with ±0.005 mm tolerance and 100% inspection before they ship.
Most bad machining experiences start before the spindle turns.
A stalled prototype costs a week of build time. When the quote lands days late and the DFM notes come after, the schedule is already gone. We return pricing and manufacturability feedback within 12 hours of receiving your file.
You need 20 parts to prove the design. Volume-only shops either decline or price the low run so high it kills the project. We run from a single prototype up to 10,000+ piece production on the same machines and the same inspection process.
A M6 tapped hole drilled at 5.1 mm instead of 5.0 mm will not hold torque. A bore at +0.03 mm over nominal will not press-fit. These errors show up at assembly, not at receiving. Every batch gets in-process checks plus final inspection before it leaves.
Anodize color shifts between lots. Bead blasting grit changes the sheen. Powder coat thickness closes a tight tolerance. We control finish from the same shop, so the part you approve in the first run stays the part you get in the tenth.
Cutting, finishing, and inspection happen under one roof.
A bracket with a compound angle, an impeller, a housing with bores on four faces. These parts need more than one setup on a three-axis mill. Every extra setup adds stack-up error and handling time. We run 16 simultaneous 5-axis machining centers and 16 mill-turn centers, so angled faces, deep pockets, and turned-and-milled features come off in one or two operations.
Part size decides the machine. Compact work up to 500 × 500 × 450 mm runs on our smaller verticals. The medium envelope covers 750 × 1,150 × 550 mm and 600 × 600 × 600 mm. For long parts, the large travel reaches 4,000 × 400 × 150 mm. If your part fits one of those windows, we can quote it without a special fixture review.
Holding ±0.005 mm on a production run means controlling temperature, tool wear, and fixture rigidity. On aluminium and stainless parts, we rough, semi-finish, and finish as separate passes so the material settles before the final cut. In-process probing catches drift before a batch is finished, not after.
Inspection is not a final gate alone. Raw material certificates are checked on arrival. Dimensions are monitored during the run. Every part is inspected before shipment, and inspection reports come on request. That sequence is what keeps a qualified shop at 99.99% qualification rate across steel, aluminium, stainless, and engineering plastics.
Use this table to decide which callout to put on your drawing.
| Part feature | Recommended process | Why |
|---|---|---|
| Flat plate with through holes | 3-axis milling | Two setups, fast cycle, lowest cost |
| Compound angles on one face | 5-axis milling | Single setup removes stack-up error |
| Turned shaft with cross holes | Mill-turn | Turning and milling in one program |
| Tapped holes under M3 | 3-axis with peck drilling | Lower tool load, fewer broken taps |
| Sealing groove, Ra 0.4 μm | Milling plus fine finish pass | Surface finish controls the seal |
| Hardened steel insert pocket | Grinding after milling | Holds bore tolerance after heat treat |
Each service runs on dedicated equipment with its own inspection plan.
Complex geometry, compound angles, and contoured surfaces cut in one or two setups. Used for housings, impellers, and structural brackets where setup error is the main risk.
Rotary work for parts with features on multiple sides. A good middle ground when 5-axis cycle time is not justified but manual refixturing is too slow.
Plates, covers, manifolds, and brackets. The most cost-effective route for prismatic parts and the fastest path to a first prototype.
Milled profiles and turned diameters, including mill-turn parts that need both. Tolerances down to ±0.005 mm on critical diameters.
Post-heat-treat finishing on hardened steel and tight bore work. Removes distortion and brings surfaces to Ra 0.2–0.8 μm when milling cannot.
Anodizing, plating, powder coating, black oxide, blasting, brushing, and laser marking. Finished in-house so tolerance and finish stay in one quality chain.
Material choice drives tooling, speed, and finish. These are the grades we run most.
| Material group | Common grades | Typical use |
|---|---|---|
| Aluminium | 6061-T6, 7075, 2024, 6082 | Enclosures, brackets, heat sinks |
| Stainless steel | 303, 304, 316L, 17-4PH | Food contact, medical, marine parts |
| Carbon and alloy steel | 1018, 1045, 4140, 4340 | Shafts, plates, tooling components |
| Copper and brass | C110, C36000, beryllium copper | Bushings, contacts, RF housings |
| Titanium and special | TC4 (Ti-6Al-4V), Inconel, AZ31B | Aerospace, high-temp, lightweight parts |
| Engineering plastics | POM, PEEK, PC, ABS, HDPE | Insulators, wear parts, prototypes |
No adjectives. Just the figures you can check against your own requirement.
Send a STEP, STP, SLDPRT, IPT, SAT, IGES, X_T, or STL file. You get pricing plus manufacturability notes the same working day, so design changes happen before tooling is cut.
That is ±0.0002 in. We hold it on production parts, not just on a first article. Achievable on most metals with the right fixture and finishing passes.
Three wholly-owned plants, 7,600 m² of floor space, and 150 technicians. Work is not brokered out to third parties you never speak to.
Parts that pass inspection on the first submission. Backed by raw material checks, in-process monitoring, and 100% final inspection before shipment.
Production can start within 24 hours of quote approval. Historical late-delivery probability sits below 2% across our order book.
One prototype or a 10,000-piece run. No minimum order quantity, and the same process controls apply to both ends of that range.
Joint housings and actuator brackets need bores that stay concentric after anodizing. We machine and finish in-house to keep that alignment.
Insulator plates and fixture bodies call for tight flatness and no burrs near contacts. Deburring and bead blasting are part of the standard route.
Replacement shafts and wear plates often arrive as a sample with no drawing. We reverse-measure, model, and cut a matched part.
STEP, STP, SLDPRT, IPT, PRT, SAT, IGES, IGS, CATPART, X_T, OBJ, and STL all work. STEP is the safest choice because it carries solid geometry and units cleanly.
If you only have a 2D drawing, send the PDF with critical dimensions marked. We will flag anything that needs a 3D model before cutting.
±0.005 mm (±0.0002 in) on critical features, with the right material and fixture. Very small holes, thin walls, and deep pockets may need a looser callout because tool deflection grows with depth.
If a tolerance is tighter than the process can hold, we say so in the DFM notes rather than quoting a number we cannot meet.
No. A single prototype and a 10,000-piece run both go through the same machines and the same inspection sequence.
Unit cost drops with volume because setup is amortized, but there is no floor below which we decline the order.
Very abrasive or gummy materials wear tooling fast or produce poor surfaces. Some filled plastics and certain high-silicon aluminium grades fall into that group.
If your part is a thin shell with no critical features, vacuum casting or sheet metal may cost less. We will point that out if it applies.
Uploads are kept secure and confidential. We can sign an NDA before you send the first file.
Files are used only for quoting and manufacturing your order, and are not shared outside the production and inspection teams.
Yes. Anodizing, plating, powder coating, black oxide, blasting, brushing, polishing, and laser marking all run in-house.
Keeping finishing on the same site matters when a coating adds thickness. We adjust the pre-finish dimension so the final part still meets tolerance.
Laser marking needs a minimum character height of 1.5 mm to stay legible. Tapped holes below M3 are possible but need peck drilling and a slower cycle.
Sharp internal corners are limited by tool radius. Adding a corner relief on the drawing usually removes the need for EDM.
Raw material is checked on arrival, dimensions are monitored during the run, and every part is inspected before shipment. Inspection reports are available on request.
For regulated programs we work under ISO 9001:2015, IATF 16949:2016, ISO 13485:2016, and ISO 27001:2022.
