What Dongguan Zhuohang Ltd is
For you qualifying a CNC machining supplier, the legal entity behind the brand is part of the risk assessment. Dongguan Zhuohang Ltd is the legal entity behind the Machining Manufacturer brand. It was registered in Dongguan, Guangdong, China in 2005 and is the contracting party on purchase orders, invoices and quality documents. If you ever needs to verify the company, the registration number can be checked against the official business registry of China.

How the entity relates to the Machining Manufacturer brand
Machining Manufacturer is the marketing brand shown on this site; Dongguan Zhuohang Ltd is the legal person that signs contracts, issues invoices and takes quality responsibility. The two are the same company — the brand is how the company presents itself to buyers, the legal entity is how it exists in law.
Why the legal entity matters to buyers
- Contract certainty — your purchase order, PI and invoice name one entity, so there is no ambiguity about who owes the performance.
- Verifiability — the registration number is public record; you can check the company exists before you pay a deposit.
- Quality accountability — certificates (ISO 9001, IATF 16949, ISO 14001) and inspection records are issued under this entity's name.
Why the same entity should carry a part from sample to production
A common pattern goes wrong quietly: a buyer qualifies with a prototype, approves the sample, places a production order, and the parts arrive from somewhere else. The geometry is right and the material certificate looks fine, so the problem stays invisible until a dimension drifts and nobody can say which process changed. The root cause is usually that the entity that made the sample is not the entity contracted for production.
Holding one contracting party across both stages removes that failure mode. The programmer who proved the process on the first article is the same person who holds it in production; the inspection data from the sample is directly comparable to production data because it came off the same equipment under the same quality system. When sample and production are split across suppliers, that comparability is gone and every later investigation becomes a negotiation.
What does not change between prototype and production
| Element | Prototype | Production | Held constant by |
|---|---|---|---|
| Contracting party | Dongguan Zhuohang Ltd | Dongguan Zhuohang Ltd | One registered legal person, 91441900MA4UWT6X39 |
| Quality system | ISO 9001:2015 | ISO 9001:2015 + IATF 16949:2016 | Certificates held by the same entity, issued by URS |
| Equipment | Same floor | Same floor | 100+ machines in one 6,800 m² facility |
| Inspection | CMM + XRF | CMM + XRF, SPC added | One documented inspection process |
The practical consequence is a shorter route to a stable process. With no minimum order quantity — the minimum is 1 piece — a first article can be run on production equipment rather than on a bench, so the capability study from the sample is meaningful rather than optimistic.
Where the IATF scope ends
Precision matters here because buyers routinely over-read a certificate. Dongguan Zhuohang Ltd holds IATF 16949:2016 under certificate number 131941/A/0001/SM/En, and that certificate excludes clause 8.3, product design. In plain terms: the certified system governs manufacture to your drawings — APQP, PPAP, FMEA, MSA, SPC and traceability — but not the act of designing the part. For build-to-print work, which describes most CNC sourcing, this is exactly the scope you need. If you want a supplier to own design, that has to be written into the RFQ instead of assumed.
The two other certificates complete the picture differently: ISO 9001:2015 (116024/A/0001/UK/En) covers the quality management system itself — documented processes, corrective action, internal audit — and ISO 14001:2015 (116024/B/0001/UK/En) covers environmental management. Neither guarantees that a specific part meets a specific tolerance; nothing does. What they establish is that the processes around the machining are audited and documented by an external body.
Frequently asked questions
Will the same entity make my prototype and my production run?
Yes. Dongguan Zhuohang Ltd (registration number 91441900MA4UWT6X39) contracts both, on the same floor and under the same quality system, so first-article data stays comparable to production data.
What is the minimum order quantity?
There is none — the minimum is 1 piece. Prototypes can therefore run on production equipment rather than a separate bench, which makes early capability data meaningful.
Does the IATF certificate cover design?
No. Clause 8.3 (product design) is excluded from the IATF 16949:2016 certificate (131941/A/0001/SM/En). It covers manufacture to your drawings. Design responsibility must be stated explicitly in your RFQ.
Who issued the certificates?
All three were issued by URS: ISO 9001:2015 (116024/A/0001/UK/En), IATF 16949:2016 (131941/A/0001/SM/En) and ISO 14001:2015 (116024/B/0001/UK/En). Each can be verified with the registrar.
Where is production located?
No. 8, Shuibian Songyuan Road, Hengli Town, Dongguan, Guangdong, China 523470 — roughly 6,800 m², more than 100 people, 100+ machines.
