A complete guide to CNC machining bronze: alloy selection table (C932, C954, C510, C544, C655), verified cutting parameters, real material cost data, and a step-by-step workflow for sourcing verified bronze CNC parts from China.
China’s CNC machining industry sets the global benchmark for precision and efficiency. Explore the top 10 factories of 2025. Each verified, certified, and trusted by leading OEMs worldwide.
Xometry isn't your only option. We compared 7 manufacturing platforms, pricing models, supplier networks, NDA protection, using data from each company's own site.
Choosing the wrong plastic prototyping method wastes time and money - a CNC-machined part for a simple geometry check, or a 3D print for a load-bearing functional test.
Blind holes are one of the most commonly misspecified features in CNC machined parts. When you submit an RFQ without a depth callout, a bottom geometry type, or a thread depth separate from drill depth, the factory guesses - and the wrong part only surfaces at assembly.
Injection molding tooling cost from China ranges from $1,000 for a single-cavity prototype mold to $80,000+ for complex multi-cavity production tooling - a range accurate enough to publish but useless for budgeting. This guide breaks down real factory pricing by steel grade and cavity count, explains the 5 variables that cause identical-looking quotes to differ by thousands, and shows how to structure an RFQ that forces comparable numbers.
Trading companies outnumber real factories on most Chinese sourcing platforms, and their listings look identical to the genuine article. This guide covers the 5 verification checks that confirm factory status before you share files or commit a tooling budget.
Instant CNC quote tools return prices in seconds. But for complex parts, the algorithm builds in a pricing buffer instead of accurately pricing the job. Going direct to Chinese factories is accurate but slow and unverified. This guide covers when instant quote tools are reliable, when direct factory contact makes more sense, and a third approach that returns real factory quotes within approximately 24 hours.
The same CNC drawing sent to multiple Chinese factories can return quotes that vary by 3x for identical parts - almost always because of incomplete RFQ specifications. This guide covers the exact file package, material grades, tolerance callouts, and surface finish values needed to get accurate, comparable quotes from China, and explains why incomplete RFQs trigger a 15-25% risk premium before production even starts.
