Custom CNC Parts Manufacturer
in Dongguan, China

A custom CNC parts manufacturer is a precision machining company that produces one-of-a-kind or short-run parts based on customer-supplied designs (CAD files or drawings) instead of off-the-shelf catalog items. Ginwate CNC is a Dongguan, China-based custom CNC parts manufacturer producing single-piece prototypes through 10,000+ unit production runs across aluminum, stainless steel, titanium, brass, copper, steel and engineering plastics.

No minimum. We accept single-piece prototypes at the same quality as production runs — no setup fee penalty, no inflated single-unit pricing. This is unusual in the CNC industry and a deliberate choice to serve startups, DIY builders, students, makers and prototype engineers as well as OEM clients.

Standard lead times: 3–5 business days for prototypes and small batches, 7–15 days for production volumes. Rush orders (24–72 hour turnaround) available for simple parts when machine capacity allows. Quote response within 1–12 hours of file submission.

STEP (preferred), IGES, STL, SolidWorks (.SLDPRT / .SLDASM), DWG, DXF, PDF, X_T. Send a 2D drawing alongside the 3D model so we can verify dimensions, GD&T callouts and surface finish requirements. Hand sketches accepted for simple parts — we'll redraw in CAD at no charge.

Single prototypes typically run $30–$400 per part depending on material, complexity and tolerance. Small batches (5–50 pcs) drop to $15–$180/piece. Production volumes (100–1,000 pcs) range $5–$60/piece. Exact pricing depends on: material (aluminum cheap, titanium expensive), machining time (complexity), tolerance (tight tolerance = slower cuts), surface finish, and post-processing. Send your file for an exact quote in under 12 hours.

Metals: Aluminum 6061/7075/2024/5052, Stainless Steel 303/304/316L/17-4 PH, Titanium Grade 2/Grade 5, Brass C360/C260, Copper C101/C110, Steel 4140/4340/H13/D2, Inconel, Monel. Engineering plastics: POM/Delrin, PEEK, PTFE/Teflon, Nylon, ABS, Polycarbonate, Acrylic, UHMW. Glass-filled and carbon-filled variants of most plastics available.

±0.005 mm (5 microns) on critical features when the drawing specifies. Standard production tolerance is ±0.01 to ±0.025 mm depending on feature size and material. We use Hexagon CMM and Trimos height gauges for verification, with FAI report on first article available on request.

Yes. Our 5-axis CNC machining centers handle complex geometry, undercuts, organic surfaces and multi-face features in a single setup — eliminating the cumulative stacking error that comes from re-fixturing on 3-axis machines. Common 5-axis custom parts: turbine impellers, aerospace brackets, medical implants, orthopedic guides, complex housings.

Yes — about 15% of our orders are single-piece DIY/hobby parts. We don't gate by company size or order volume. Drone builders, robotics enthusiasts, prop makers, automotive modders, RC builders and students all send us files. Same quality, same tolerances, same lead times as our OEM clients. No minimum, no surcharge for single pieces.

Yes, at zero cost. Email your NDA to redowan@gh-goldenhot.com and we'll sign and return before accessing your files. Your IP and CAD files are stored on encrypted servers and never shared with third parties — including other Ginwate clients. Standard mutual NDAs accepted; custom NDAs reviewed within 24 hours.

30+ finishes available in-house: anodizing (Type II, Type III hard-coat, any RAL/Pantone color), electroplating (nickel, chrome, zinc, gold), powder coating, PVD coating (gold, black, titanium), black oxide, passivation, bead blasting, sandblasting, polishing (mirror finish), brushed/satin, electropolishing. We pre-compensate machined dimensions when plating affects tolerance so finished parts hit drawing.

Yes — to 50+ countries. Daily DHL / FedEx / UPS pickup from our Dongguan facility. Air freight 3–7 days door-to-door to North America, Europe, Australia, Middle East. Sea freight for heavy or high-volume orders. Full export documentation, packing list, COC and material certs included. DDP (Delivered Duty Paid) terms available.

First Article Inspection (FAI) report with dimensional data, Material Certificate showing alloy and heat number, Certificate of Conformity, surface finish (Ra) reports where specified, full export packing list and shipping tracking. Free with every order — no extra documentation fee.

Three differences. (1) China-based manufacturing — 30–60% lower piece prices than US/EU competitors with same tolerances. (2) Human engineering review on every quote — your file lands with a senior CNC engineer (not just an algorithm) who flags DFM issues before machining begins. (3) Direct relationship — same engineer reads your file, runs the quote, and emails when your part ships. No layers of account managers.

Yes. Upload your file at /quote, get an automated estimate within minutes, and place an order with credit card (under $500) or wire transfer (above $500). A senior engineer still reviews every file before machining — but you don't have to schedule a sales call. Many customers go from quote to shipped part without a phone call.
