Who should I contact for a quote?
The single point of contact is Felipe Iglesias, Business Development Director, at [email protected] or +86 13126536955 (also WhatsApp). He handles inquiries in English, Portuguese, Spanish, French, and Chinese; Japanese is covered by Anna Tian, our Japan market lead.
One email does two jobs: name the alloy and attach the drawing in the same message. The alloy sets the process; the drawing sets the geometry, and both belong in writing before you commit.
Why does the alloy matter on the quote request?
Because "steel" is not a material. 12L14 and 4340 are two different jobs; 303 and 316 are two different jobs. They run at different speeds, wear tools differently, and land in different lead-time tiers. A quote that guesses the alloy is guessing the price.
When you send the exact grade up front, the process is matched on the first pass — Swiss-type for a slender brass pin, standard turning for a 4140 flange, mill-turn for a part with cross-holes — and the quote reflects the material you will actually receive, verified by XRF against its mill certificate.
What should you send for an accurate quote?
The cleaner the input, the faster and more accurate the quote. Four items cover it:
| Item | Why it matters |
|---|---|
| Exact alloy | Sets the speed, tooling, and cost — 303 vs 316 is a different job |
| 2D drawing with tolerances | States which diameters are critical and the datum scheme |
| Quantity and target date | Sets the setup economics and the schedule |
| Heat treatment / finishing | Decides whether grinding or a longer tier is needed |
Where is the factory, and how do I visit?
The factory is at No. 8, Shuibian Songyuan Road, Hengli Town, Dongguan, Guangdong, China 523470 (GPS 23.048947, 113.990605). Email ahead to book a visit so the right engineers and quality staff are available; a visit typically covers the turning floor, the inspection bench, and the documentation.
What should you verify during a visit?
An hour on site answers what no email can. Bring the drawing you care about and check these five things:
- The certificate number matches what the registrar lists for Dongguan Zhuohang Ltd
- The turning machines match the list — Swiss-type, lathes, mill-turn, on the floor and under power.
- The material control is real — ask to see the XRF check against a mill certificate.
- An engineer can read your drawing and explain which machine and tooling your part needs.
- The documentation is traceable — ask to see a recent SPC chart and material certificate.
What happens after you send a drawing?
The sequence is short and predictable: the file goes to a design-for-manufacturing review, the alloy is confirmed, manufacturability issues are flagged before quoting, and a quote is returned with the lead-time tier (roughly 3 / 7 / 30 days) and the MOQ confirmed at 1 piece. If a diameter cannot be reliably held in your material, you are told up front — before cutting, not after.
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.
Certifications: ISO 9001:2015 (116024/A/0001/UK/En), IATF 16949:2016 (131941/A/0001/SM/En, design clause 8.3 excluded - disclosed openly), ISO 14001:2015 (116024/B/0001/UK/En). Certificates are issued to Dongguan Zhuohang Ltd (USCC 91441900MA4UWT6X39, established 2005).

Frequently Asked Questions
Who should I contact for a quote?
Felipe Iglesias, Business Development Director. Email [email protected] or call +86 13126536955. He responds in English, Portuguese, Spanish, or French, with Japanese handled by Anna Tian, our Japan market lead.
What alloy information do you need?
The exact alloy, not a generic metal or steel — 303 versus 316, or 12L14 versus 4340, are different jobs with different speeds, tooling, and lead times. Naming the grade up front gets the process and the quote right on the first pass.
Can I book a factory visit or audit?
Yes. Visits and audits are welcome at No. 8, Shuibian Songyuan Road, Hengli Town, Dongguan (GPS 23.048947, 113.990605). Email ahead so the right engineers are available.
What should I send for an accurate quote?
A 3D STEP or IGES file, a 2D drawing with tolerances and the exact material called out, the quantity and target date, and any heat treatment or surface finishing requirements.
How fast will I get a response?
Quotes are returned after a design-for-manufacturing review, and inquiries are answered promptly. Sending a clean STEP file plus a toleranced 2D drawing with the alloy named produces the fastest, most accurate response.
