Who is your point of contact?
Felipe Iglesias is the business development director. He works in English, Portuguese, Spanish, French, and Chinese. Reach him at [email protected] or +86 13126536955.
What should you send to get a DFM review?
- A 3D file (STEP or IGES) and, for complex parts, a 2D drawing with critical dimensions.
- Material and finish — alloy, heat treatment, and surface treatment.
- Quantity and cadence — order quantity and annual volume.
What happens on a factory visit?
You walk the machine floor and see how a DFM review becomes a production process — the machines, the inspection bench, and the people.
What should you prepare before a visit or a first email?
- Your part files — 3D and, where possible, a toleranced 2D drawing.
- Your requirements — material, finish, quantity, and target date.
- Your design questions — where you suspect the cost is.
How do you stay connected after the first order?
- Status weekly on open orders, with a written report on request.
- Feedback that survives the first order: manufacturability comments and the route decided from them stay in the setup sheet and control plan.
- Fixtures, programs and capability history kept, so a repeat batch runs the accepted condition on the same machine group.
- Documents matched to the part: CMM reports, SPC charts and material certificates, with PPAP or FAI on request.
- Root cause traced from the lot record in the MES and ERP system rather than reconstructed from memory.
How to get a manufacturability review with your quote
Send these seven items and the reply covers both price and design feedback:
- A STEP or IGES model, since a review needs geometry rather than a PDF alone.
- A 2D drawing with tolerances, datums and notes, marking critical characteristics.
- Material grade and condition, including temper or hardness where it applies.
- Finish, and whether coating thickness sits inside the toleranced dimension.
- Order quantity and expected annual quantity, because the route can change with volume.
- Function in one line for any feature whose purpose the drawing does not show.
- Target date, and whether it is fixed or preferred.
Email [email protected] or call +86 13126536955. Felipe Iglesias handles technical inquiries in English, Portuguese, Spanish, French, and Chinese, and MOQ 1 piece means a single validation part is a normal order rather than a favor.
A two-hour plant walk, in the order the part travels
| Stop | What is in front of you |
|---|---|
| Goods-in | XRF spectrometer checking incoming lots against mill certificates, with lots labelled and segregated |
| Milling cells | 50+ 3-axis, 20+ 4-axis and 20+ 5-axis centers, envelope to 1300 × 700 × 600 mm |
| Turning | 25+ lathes to Ø720 × 1280 mm, with sliding-head machines for slender parts |
| Grinding | 7+ machines for surface, centerless and cylindrical work to ±0.002 mm |
| Heat treatment | In-house ovens to 500 °C, with higher-temperature titanium work placed externally |
| Inspection room | Two Hexagon GLOBAL S CMMs, KEYENCE VK-X3000, SURFCOM 1800D and more, inside 20+ instruments |
| Packing and documents | Surface protection for finished parts, and paperwork issued in the legal entity's name |
Total floor area is 6,800 m² with 100+ staff, so the walk is long enough to be informative and short enough to finish before lunch.
What happens after you send the files
The model is checked against the machine envelope first, because a part that does not fit is worth knowing about in an hour rather than a week. The route is then set: number of setups, machine group, workholding, and whether grinding or heat treatment is needed. Manufacturability comments are written against specific features rather than offered as general advice, and each one states the consequence of leaving it as drawn. The quote states the process route, the lead-time tier of roughly 3, 7 or 30 days, and the inspection scope. On release, material is verified by XRF against the mill certificate, the first part is measured before the batch continues, and documents are compiled to match the part. One contact stays with the job from inquiry to shipment.
What this shop actually runs
A buyer asking for capability evidence should get a specific answer. The facility behind this guide operates 100+ CNC machines across a 6,800 m2 plant in Dongguan, China, with 100+ staff. The machine list by category:

Run on compound-angle parts, single-setup multi-face prismatic work, and aerospace fittings where datum transfer loss is unacceptable.
- 3-axis / 4-axis machining centres (50+) - Brother SPEEDIO S500Z2N / S700Z2N (10,000 rpm, 14/21-tool ATC, 0.7 s tool-to-tool, Z-axis 2.2 G) and Mazak VCE-430A L / VCE-570C L (10,000 rpm, 118 N·m, 24-tool ATC). Run on prismatic parts, plates, brackets, housings.

- CNC turning centres (20+) - HEADMAN T70M/1250 (720 mm swing, 117 mm bore, 3,000 rpm, BMT75 12-station turret). Run on shafts, bushings, flanges up to ±0.002 mm.
- Wire EDM (5+) - Sodick AQ535L (550/350/300 mm travel, ±20° taper, 800 kg workpiece). Run on hardened tool steel, internal splines, sharp internal corners that milling cannot reach.
- Inspection: Hexagon CMM + 20+ gauges - Hexagon CMM for coordinate measurement, plus vision system, profilometer, hardness tester, coating thickness gauge, XRF for material verification. The 10:1 rule (gauge 10x more accurate than the band) is applied to every feature.
- Machine highlights - VARIAXIS I-600: one-setup multi-face 5-axis + MAZA-CHECK auto-calibration; INTEGREX I-250H S: DONE-IN-ONE mill-turn, B-axis 0.0001° + Ai thermal shield; SPEEDIO S500Z2N / S700Z2N: Z-axis 2.2 G + 0.7 s ATC; Swiss-type: guide-bush switchable + 0.1 µm resolution.
