How do you reach the factory directly?

The direct line is +86 13126536955 and the email is [email protected]. Contact Felipe Iglesias. Writing to the factory directly means the person quoting your part knows the floor, the machine list, and the volume economics. State the part, material, tolerance, and expected volume and cadence so the reply is specific.

Who is your point of contact, and what languages?

Your contact is Felipe Iglesias at [email protected]. Correspondence runs in English, Portuguese, Spanish, French, and Chinese. Keep the drawing attached and critical dimensions called out so the volume discussion stays precise.

What should you send to get a quote at the right volume?

Send the drawing, the material specification, the required tolerance, and your expected volume and cadence (one-off, bridge, or steady production). We return a price separating setup from piece cost and name the process recommended at your quantity, with lead time from the 3 / 7 / 30 day ladder.

What happens on a factory visit?

A visit to No. 8, Shuibian Songyuan Road, Hengli Town, Dongguan lets you count the machines, see the Hexagon CMMs and KEYENCE microscope, and confirm the legal entity Dongguan Zhuohang Ltd (registration 91441900MA4UWT6X39) in person. It is the strongest diligence step and we schedule it through the contact above.

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

Bring the drawing with critical dimensions marked, the material specification, the tolerance, and your volume plan. The more precise the input, the more precise the volume answer. If the design is not final, send the closest revision and note what may change.

How do you stay connected after the first order?

After the first lot, keep the same contact for reorder and engineering changes. Because we are build-to-print, every revision is a new drawing release, and the measurement record from the first run becomes the baseline for the next. That continuity is how a one-off prototype becomes a stable production supply without re-qualifying the shop.

What makes a volume quote accurate the first time?

Send the drawing, the material specification, the required tolerance, and your expected volume and cadence, whether that is a one-off, a bridge order, or steady production. The more precise the input, the closer the quote is to the landed cost, because we separate setup from piece price and name the process we recommend at your quantity. Incomplete inputs are the most common cause of a slipped lead time and a surprise at reorder, because the shop has to guess at a tolerance or a finish and then rework the guess.

State the acceptance criteria up front: packaging, marking, inspection level. Tell us whether the part needs individual wrapping, a laser mark, or a full first-article package, and we build it into the quote instead of discovering it after the lot is cut. A quote that hides these choices is not cheaper — it is unfinished.

How are engineering changes handled as volume grows?

Because we are build-to-print, a change is a new drawing release, not a phone call. We re-run the measurement baseline from the first lot against the new print and tell you exactly what moved. Your contact Felipe Iglesias keeps the thread, so the change is tracked in writing instead of lost in a reseller's inbox. That continuity is what keeps a prototype program from stalling at every revision, and it is why the same supplier can carry you from one part to volume without re-qualifying the shop.

For you, predictable change control protects unit cost at scale, because a late change on a ten-thousand-piece run is far more expensive than the same change on part one. Keep the same contact and file history, and scaling stops being a gamble.

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). 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.

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.
