China CNC Machining Manufacturer — AS9100D & ISO 13485 Certified OEM/ODM Factory

CNC machining cost depends on six variables — material, geometric complexity, tolerance, surface finish, quantity, and lead time — so a single price doesn't exist. As benchmarks from our recent shipments: a 50 mm aluminum 6061-T6 bracket with ±0.05 mm tolerance and Type II anodizing runs roughly $8 to $14 per piece at quantity 100. A titanium aerospace bracket with ±0.005 mm critical features, AS9102 documentation, and certified material runs roughly $85 to $180 per piece at quantity 50. A stainless steel precision shaft for surgical robotics runs roughly $35 to $90 per piece at quantity 50, including passivation and cleanroom packaging. Send us a drawing and we will return a complete itemized quote within 12 business hours — including material, machining, finishing, inspection, and shipping cost broken out separately so you can benchmark against your domestic supplier honestly.

Lead time depends on quantity, complexity, and finishing requirements. Prototype quantities of 1 to 10 pieces typically ship in 5 to 10 working days. Small production runs of 50 to 500 pieces typically ship in 2 to 3 weeks. Production runs in the thousands typically ship in 3 to 5 weeks, depending on capacity and surface finishing. Once parts ship from our Dongguan facility, international air freight to the United States or Europe runs 3 to 5 business days door-to-door via DHL, FedEx, or UPS. Ocean freight and consolidated LCL shipping are available for cost-sensitive production work. Lead times and shipping options are confirmed in writing with your quote, so you can plan your inventory and launch schedule with confidence.

Intellectual property protection is one of the most important questions our customers ask, and we take it seriously. MID Precision signs mutual non-disclosure agreements (NDAs) on request — we sign yours, or we provide ours, before any drawing exchange. Drawings and CAD files are stored on access-controlled internal servers, distributed only to the specific engineers and machinists working on your project, and never shared with sub-contractors without your written approval. We do not maintain a public "showroom" of customer parts, and we do not use customer parts in marketing without explicit written permission. Our China-based legal structure allows enforceable IP commitments under Chinese law, and our 30-year track record with US, EU, and Israeli OEM customers confirms our reliability on this point in practice, not just on paper.

Yes. MID Precision is a full-service OEM and ODM partner. OEM (Original Equipment Manufacturing) means you provide finished engineering drawings and specifications, and we produce parts exactly to your print under your brand or as direct supply to your assembly. ODM (Original Design Manufacturing) means our engineering team participates in part design, material selection, DFM optimization, or full-design work for clients who do not have in-house mechanical engineering. In either model, your IP is protected by signed NDA, your drawings stay confidential, and the parts ship under your purchase order — not ours. Most of our Fortune 500 aerospace and medical clients use the OEM model; most of our startup and small-OEM clients use ODM. Tell us where you sit on that spectrum and we will quote accordingly.

There is no minimum order quantity. We routinely produce one-piece prototypes, five-piece R&D samples, and fifty-piece pilot batches for engineering customers who need to validate a design before committing to full production. Single-piece prototype quotes typically come back the same business day. We do not penalize low-volume orders with disproportionate setup fees — our small-batch CNC cell is built around the realities of engineering development, where designs change weekly and the next revision is more important than the lowest unit cost. As your design freezes and your volumes ramp, the same parts move to our production cell with identical process documentation and the same project manager, so you do not have to re-qualify your supplier for full-rate production.

The majority of surface finishing is performed in-house at MID Precision, including bead blasting, sandblasting, tumbling and vibratory deburring, manual polishing, mirror polishing, brushing, and passivation per ASTM A967. Anodizing (Type II and Type III hardcoat), electroplating (nickel, chrome, gold, silver, tin, zinc), powder coating, electropolishing, and DLC coating are performed by long-term partner suppliers within our local Dongguan industrial cluster — typically within a 30-minute drive from our facility — under our direct quality oversight and audit. We coordinate all finishing operations as a single project, so your purchase order is for a finished part, not a machined blank that still needs to be sent out for coating. This single-source approach eliminates a major source of delivery delay and quality finger-pointing.

Three reasons our customers cite when they switch to MID Precision. First, our certification stack — AS9100D, ISO 13485, ISO 9001 — lets a single supplier handle aerospace, medical, and industrial OEM/ODM work without forcing you to onboard multiple vendors. Second, our 30-year track record on tight-tolerance and complex 5-axis work means we consistently deliver parts that other shops quote and then fail to produce. Third, our pricing reflects the reality of factory-direct manufacturing in Dongguan — typically 30 to 50 percent below comparable domestic US or EU CNC machining work, without compromising tolerances, traceability, or delivery. The best way to evaluate us is to send us a drawing your current supplier is struggling with and let our quote, our DFM feedback, and our first article performance make the case for themselves.
