Swiss CNC Machining Factory

The factory sits in Hengli Town, Dongguan, in the Pearl River Delta — a region that concentrates machining capacity the way other regions concentrate finance or software. The address:

No. 8, Shuibian Songyuan Road, Hengli Town, Dongguan, Guangdong, China 523470.

Being in Dongguan matters for two reasons you should weigh deliberately. First, the supplier base for raw bar, plating, heat treatment, and tooling is dense, which shortens the handoffs that a slender part picks up between operations. Second, it is reachable — Dongguan is a short trip from Shenzhen and Hong Kong, and we open the floor to visits and audits. A location claim is easy to fake; a factory you can walk through is harder.

Who Runs the Place, and Who Talks to Buyers?

The floor is run by a technical team — over 80% skilled technicians, around 60% with five to ten years of experience — and the buyer-facing contact is an engineer, not a call center. Felipe Iglesias handles quotes and technical review directly at [email protected], which means the person reading your drawing is the person answering your tolerance questions.

The sales team works in English, Japanese, Portuguese, Spanish, and French, and after-sales support runs through partners in Japan, the UK, Canada, and Australia, so a buyer in those regions is not left chasing a time zone alone. The distinction matters: on a slender part, the clarifying question about a tolerance is worth more than a fast generic quote, and an engineer-led contact is the one who asks it.

How Does the Factory Handle Environmental Responsibility?

Machining is a resource-heavy trade, and the factory runs under ISO 14001:2015 — environmental management tied to the machining of metal parts. In practice that means a roof covered with solar panels generating roughly 20,000 kWh of green power a month, and documented controls for noise, waste water, and air emissions.

The labor side is governed by the same seriousness: no forced or child labor, contracts signed on day one, social insurance for every employee, legal working hours with at least one rest day a week, and overtime paid as required. A code of conduct covers ethics, anti-bribery, confidentiality, and IP protection — including how customer drawings and data are stored and disposed of. For you sending a proprietary slender-shaft design, that last point is not a footnote.

The environmental controls and the labor standards are two halves of the same discipline: a shop that runs a documented, third-party-surveilled system is one where the process is written down, not improvised. For you sending a proprietary slender-shaft design, the IP and confidentiality clauses in that system matter as much as the machine list — a drawing that leaves the building is a part that can be copied, and the controls that protect it are part of what you are buying.

What Should You Ask Before Visiting?

Whether you buy from this factory or another, a visit is only useful if you know what to look for. Ask these questions of any shop — including this one.

Which Certifications and Registrations Back This Floor?

A factory's paperwork is the cheapest pre-audit you can run, because a certificate means a third party has already walked the floor and checked the system. We hold three, with the numbers stated so you can verify them rather than take a logo on faith.

StandardCertificate numberWhat it covers
ISO 9001:2015116024/A/0001/UK/EnQuality management for machining of metal parts
IATF 16949:2016131941/A/0001/SM/EnAutomotive-quality manufacture of CNC metal parts
ISO 14001:2015116024/B/0001/UK/EnEnvironmental management for machining of metal parts

The company itself is registered as Dongguan Zhuohang Ltd under number 91441900MA4UWT6X39, founded in 2005 — details you can check against public records before a visit. The IATF 16949 scope excludes product design under Clause 8.3: we are a build-to-print manufacturer, which we state plainly rather than over-promising.

How Does a Job Flow From the Bar Rack to the Shipping Dock?

The physical layout of the floor mirrors the order of operations, which is why a job does not travel far between steps. Incoming bar is logged and checked at the door, then moves to the Swiss-type and turning cells, then to milling or grinding where a feature calls for it, then to the metrology room, and finally to packing and shipment.

  1. Incoming. Bar and raw material arrive, are verified against the mill certificate, and are racked by lot so traceability starts before the first cut.
  2. Turning. Swiss-type cells and conventional lathes cut the primary geometry; slender parts run through the guide bushing, larger diameters through the chuck.
  3. Secondary. Milling, mill-turn, and grinding add flats, slots, cross-holes, and ground seats in the same building.
  4. Finishing. Deburring, surface finishing, and heat treatment happen in-house or through qualified partners before the parts return for final checks.
  5. Metrology and shipment. The CMM and surface-finish benches sign off on the critical dimensions, and the parts ship with their material and inspection records.

A layout that keeps these steps under one roof is not a talking point; it is what keeps a slender part from accumulating setup error and handoff time between buildings. When you walk the floor, follow the path of a single part and watch whether the distance between operations is steps or truck trips.

What Does your Audit of This Factory Cover?

An audit is only as good as the checklist behind it. Whether you send your own team or a third party, the items below are the ones that separate a producing floor from a showroom.

We open the floor to visits and to live video walkthroughs, and we hold ourselves to the same list — if a question on it cannot be answered on the spot, that is a signal, and we treat it as one.

Why Does the Location Change Your Sourcing Math?

Dongguan sits in the Pearl River Delta, a region that concentrates machining the way other regions concentrate finance. For a slender-part buyer, that density matters in three practical ways. First, the supplier base for precision bar, plating, heat treatment, and tooling is within reach, so the handoffs a part picks up between operations are short. Second, the port network — with Shenzhen and Hong Kong nearby — keeps freight routable rather than exotic. Third, the labor pool skews technically trained, which is what a Swiss-type cell needs to keep a guide bushing running true shift after shift.

None of that replaces your own due diligence, but it is the reason the location appears in the sourcing math at all: a factory that can reach its suppliers in hours, and a port in a day, is a factory that holds a lead time instead of explaining it away.

What is your company registration number?

In short, Dongguan Zhuohang Ltd is registered under number 91441900MA4UWT6X39, founded in 2005.

Can you show the certificate numbers for your certifications?

Yes. ISO 9001:2015 is certificate 116024/A/0001/UK/En, IATF 16949:2016 is 131941/A/0001/SM/En, and ISO 14001:2015 is 116024/B/0001/UK/En. We state the numbers rather than asking you to take a logo on faith.

What happens to a mixed or out-of-round bar lot at incoming?

In short, Incoming bar is verified by XRF against the mill certificate before it reaches a machine, and a lot that does not match — the wrong alloy, an out-of-round condition, or a suspect certificate — is isolated and rejected at the door. The point is to catch a bad lot before it ever reaches the guide bushing, where it would bind and push the part off tolerance.
