Who do you contact, and in which languages?
Reach Felipe Iglesias, the business development director, at [email protected] or +86 13126536955. He handles inquiries in English, Portuguese, Spanish, French, and Chinese, with Chinese support available from the team. A named contact is itself a signal — a real factory puts a person in front of you, not a ticket queue.
Can I visit the factory?
Yes. Factory visits are welcome, and if you ask to walk the floor, you are doing the audit right. Bring a drawing or a sample part so the visit can include a real design-for-manufacturing conversation — which is where hidden cost gets priced out — not just a tour.
What should you check during the visit?
A site visit confirms the shop behaves the way its paperwork claims. Structure it around four checks:
- The floor against the list. Walk the machine list and match it to the floor — Mazak, Brother, Citizen, Star, and Tsugami, a floor of 100-plus machines.
- The metrology lab. Watch the CMM produce a real measurement, and read the calibration stickers.
- The paper trail. Material certificates, first-article reports, and the scrap and rework records most buyers skip.
- The people. Ask an operator how a tight tolerance is held in production. A shop where the operator can answer in plain terms has a process, not a script.
How do you reach the factory from the airport?
The factory sits in Hengli Town, Dongguan, Guangdong, reachable from Shenzhen Bao'an or Guangzhou Baiyun airports. Send your arrival details to [email protected] and we will arrange directions or local transport for the visit.
How do you send a drawing for a total-cost quote?
Email your STEP, IGES, or 2D drawing to [email protected] with the material, quantity, and finish requirements. You receive a quote that separates piece price, tooling, finishing, inspection, and lead time — a total cost you can actually compare, with any DFM issue flagged before you commit.

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). Typical work: 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). Typical work: 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). Typical work: 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). Typical work: shafts, bushings, flanges up to ±0.002 mm.
- Wire EDM (5+) - Sodick AQ535L (550/350/300 mm travel, ±20° taper, 800 kg workpiece). Typical work: 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.
