Who do I contact for a DFM review?
Contact Felipe Iglesias, the business development contact, at [email protected] or +86 13126536955. English, Portuguese, Spanish, French, and Chinese are spoken, so you can discuss the design in the language you are most comfortable with.
What should I send to get a DFM review?
Attach a 3D STEP or IGES file plus a 2D PDF with tolerances on the critical features only, and state material grade, finish, and quantity. That package returns a DFM review — flagging walls, holes, radii, and tolerances — alongside the quote.
Where is the factory located?
No. 8, Shuibian Songyuan Road, Hengli Town, Dongguan, Guangdong, China 523470. The Chinese address is 广东省东莞市横沥镇水边松元路8号. It is a 6,800 m² facility in Hengli Town, Dongguan, where the DFM review happens.
How fast does the DFM review come back?
Quote requests are answered normally within one business day, and the design-for-manufacturability review arrives with the quote — flagging any dimension that cannot be held or feature driving cost, before you commit.
How do I validate the design before volume?
Order one part at the MOQ of 1 piece, measure it, and confirm the design machines as the DFM review predicted. That single part validates the design and the process together before volume.
What happens after I approve a quote?
After approval, the material is XRF-checked, a first article is machined and measured, and volume follows the report. Production runs ship with CMM reports and SPC charts, confirming the DFM held.
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:
- 5-axis machining centres (10+) - Mazak VARIAXIS I-600 (510/910/510 mm travel, 12,000 rpm, 22 kW, 71.6 N·m, 30-tool BT40) and Mazak INTEGREX I-250H S (B-axis 0.0001°, 24 kW, 124 N·m, 38-tool HSK-A63). Geared to 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). Geared to prismatic parts, plates, brackets, housings.
- Swiss-type turning centres (10+) - Citizen Cincom A20-3F7 (Φ20 mm, 10,000 rpm), TSUGAMI B0206-III / B0205-III (Φ20 mm, 0.1 µm), STAR SR-32JII / SR-32J Type N (Φ32 mm, 8,000 rpm). Geared to long, slender rotational parts at ±0.002 mm.
- CNC turning centres (20+) - HEADMAN T70M/1250 (720 mm swing, 117 mm bore, 3,000 rpm, BMT75 12-station turret). Geared to shafts, bushings, flanges up to ±0.002 mm.
- Wire EDM (5+) - Sodick AQ535L (550/350/300 mm travel, ±20° taper, 800 kg workpiece). Geared to 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.
Tolerance bands held: ±0.003 mm on CNC milling, ±0.002 mm on CNC turning, ±0.002 mm on precision grinding and wire EDM. Capability indices: Ppk >= 1.67 initial on key characteristics; Cpk >= 1.33 ongoing in production.

Frequently Asked Questions
How do I get a DFM review and quote?
In short, Email your STEP, IGES, or 2D drawing to [email protected], naming material grade, finish, and quantity — the review and quote return within one business day. You receive a design-for-manufacturability review and a quote, normally within one business day, before any cutting.
What is the factory address?
No. 8, Shuibian Songyuan Road, Hengli Town, Dongguan, Guangdong, China 523470 (广东省东莞市横沥镇水边松元路8号) — a 6,800 m² plant where the DFM review happens before any cutting.
How do I validate a design before volume?
Order one part at the MOQ of 1 piece, measure it against the drawing, and confirm the design machines as the DFM review predicted — validating the design and the process together before volume.
Is there a minimum order quantity?
No. The MOQ is 1 piece, so you can prove a DFM-optimized design with a single prototype before committing to a production run, and scale up as your volume grows.
