About Xinyuanmu Precision
A contract machining partner built around documentation and process honesty rather than capacity claims — because a supplier that cannot prove a part is in tolerance is not supplying a part, it is supplying a risk.
Shenzhen Xinyuanmu Precision Manufacturing is a contract manufacturer of precision machined and turned components based in Shenzhen, China. The company machines custom parts from customer drawings in aluminium, stainless steel, titanium and engineering plastics, serving semiconductor equipment, photonics and optical-communication, medical instrument and high-reliability industrial customers. It supplies prototype through small and mid-batch quantities with DFM review, first-article inspection and material traceability, and does not claim management-system certifications it does not yet hold.

What we actually do
We are a machining shop, not a broker. Orders are quoted against your drawing, reviewed for manufacturability, and machined to the tolerance stated. We focus on four sectors where the mechanical part is often the thing that decides whether an assembly works: semiconductor equipment, photonics, medical instruments and high-reliability industrial hardware.
Operating principles
These four rules explain most of the difference between how we quote and how a trading broker quotes.
We quote the process, not the customer’s expectation
If a drawing asks for something the process cannot hold repeatably, the quote says so and proposes an alternative. Accepting an impossible tolerance to win the order transfers the failure to your production line.
Every quote includes a written DFM note
The review is free and does not commit you to an order. It is the cheapest engineering hour in the transaction, and it is where most of the cost in a machined part is decided.
Documentation is part of the product
First-article inspection reports and material certificates travel with the parts, not on request. A part without a record cannot be defended in an audit.
We state what we do not do
We do not claim certificates we do not hold, and we do not pretend to cover processes we subcontract. Saying so is more useful to a buyer than a list that claims everything.
Engineering and quality approach
Every new drawing receives a DFM review before quoting, and every new part number receives first-article inspection before production. We keep the inspection and traceability records we actually generate and are explicit about which documents require a certified partner or a formal quality system we have not yet established.
Where we are, and how that affects your order
The company is based in Shenzhen, Guangdong, with access to the Shenzhen port and airport for export. Sea freight and express air options are quoted per order, and we provide the commercial invoice and country-of-origin details needed for customs entry in North America and Europe.
What we are not
We are not a broker, and we do not pass drawings to an unidentified third-party factory. We do not perform forging, casting, heat treatment, welding or grinding in-house; those operations are sourced to audited subcontractors under our incoming-inspection gate. We do not claim AS9100, ISO 13485 or ISO 9001 certification that is not yet formally held. Medical work is limited to non-implantable, non-patient-contact instrument and equipment components. Defence, aerospace-flight, nuclear and controlled-semiconductor projects are reviewed through our compliance gate before any technical data is exchanged.
