How We Work
A contract manufacturer is a group of people making judgement calls on your drawing. Rather than publish names and photographs that a buyer cannot verify, this page explains the four functional roles that decide what happens to your order — and what each one is accountable for.
Xinyuanmu Precision runs the machining business through four accountable functions: an engineering and DFM role that signs off every manufacturability review, a quality and inspection role that owns first-article inspection and records, a production planning role that commits the schedule, and a commercial role that owns the RFQ and the export relationship. One engineer is assigned to a part and stays with it through first article.
Engineering / DFM
Reviews every drawing before quoting, flags features that drive cost or cannot be held repeatably, and proposes alternatives. One engineer follows the part from review through first article.
Quality & Inspection
Owns inspection on new part numbers and the records that travel with shipments. States clearly which documents we can issue and which require a certified partner.
Production Planning
Turns the agreed scope into a production slot. Quoted dates are built from machine time and material lead time, not from a standard table.
Commercial / Technical Sales
Handles the commercial relationship, shipping terms and documentation for export customers in North America, Europe and Asia-Pacific.
How decisions get made
One engineer owns your drawing
The DFM review is not a template email. One engineer is assigned to the part and stays with it through first article, so the reasoning behind a tolerance decision does not get lost between shifts.
Lead times come from capacity
Quoted dates are built from machine hours and material lead time, not from a standard table. If a date slips, you hear it before the ship date, not on it.
Bad news travels early
If a feature cannot be held, we say so during quoting rather than shipping parts that fail incoming inspection. Declining work that suits a different process is part of the job.
Send drawings, get a review and a quote
Send a STEP file and a 2D drawing. You get a fixed-price quotation with lead time and a written DFM note — no obligation, and no sales call unless you ask for one.
