Welcome Factory Visit

How do you reach the factory?

The factory sits in Hengli Town, Dongguan — a short drive from Shenzhen and part of the densest precision-machining supply chain in the world. The full address, for a courier, a visit, or an audit:

Who is your point of contact?

Felipe Iglesias is the business development director and the person you will correspond with from first drawing to final delivery. He works in English, Portuguese, Spanish, French, and Chinese, so you are not forced through a translator for technical questions.

Reach him at [email protected] or +86 13126536955. One contact, start to finish — no hand-off between a sales rep and an engineer that loses the thread of your part.

What should you send to get a DFM review and quote?

You do not need a finished production drawing to start. Send what you have, and the review will tell you what else matters.

• A 3D file (STEP or IGES) and, for complex parts, a 2D drawing (PDF or DXF) with critical dimensions and tolerances.
• Material and finish — alloy, heat treatment, and any surface treatment such as anodizing or plating.
• Quantity and cadence — order quantity and annual volume, which change both the economics and the recommended process.

Send these to [email protected]. You get back a design review and a quote, usually within one business day.

What happens on a factory visit?

A visit is the strongest verification there is, and it costs you nothing but the trip. When you come, you walk the floor that will machine your parts and see the evidence behind the claims:

• The machine floor — a hundred-odd machines from Mazak, Brother, Citizen, Star, and Tsugami, spanning 3-axis through 5-axis, turning, mill-turn, and grinding.
• The inspection bench — Hexagon CMMs, vision measuring, XRF, and hardness testers that turn a machine's work into a signed report.
• The people — the engineers and machinists who will actually run your job, not a sales team hiding the shop.

What should you prepare before a visit or a first email?

The more complete your first message, the more useful the first reply. A little preparation turns a vague inquiry into a concrete quote.

• Your part files — 3D and, where possible, a toleranced 2D drawing.
• Your requirements — material, finish, quantity, and the date you need parts in hand.
• Your questions — ask for the registration number, certificate numbers, and machine list; a real factory sends them without hesitation.

If you are visiting from overseas, email ahead and we will coordinate the timing so the right people are on the floor when you arrive.

How do you stay connected after the first order?

A machining relationship is built on repeat work and documentation, not a single transaction. After the first order, you get the same contact, the same traceability, and the same quarterly reviews that turn a vendor into a supply base.

• Weekly status on open orders, with a report on request.
• Documentation — CMM reports, SPC charts, and material certs with every shipment.
• Corrective action, not churn — if a batch has an issue, we fix it and prevent recurrence rather than argue about it.

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