Import Brass And Copper Prototype With Highly Polished — Buy in wholesale FOB from Supplier in China

Shenzhen Ruitai Mold Technology Co., Ltd manufactures CNC-machined brass and copper prototypes with highly polished surface finish, targeted at automotive, electronics, and industrial equipment sectors requiring precision functional testing and small-batch validation. The prototypes use brass (CuZn alloy) and copper (Cu 99.9%+) stock, leveraging copper's 401 W/mK thermal conductivity and brass's superior machinability (typically 100% relative machinability rating). The supplier's capabilities span sheet metal processes including laser cutting, CNC punching, CNC folding, stamping, wire cutting, drilling, tapping, countersinking, and counterboring, with rapid prototyping offered without dedicated production tooling.

Material specifications for the brass alloy are not itemised beyond CuZn designation; standard free-machining brass C36000 (Cu 61.5%, Pb 3%, balance Zn) or C37700 (forging brass) are common for precision prototypes, with copper C11000 (ETP, 99.9% Cu) typical for high-conductivity applications. The highly polished finish suggests Ra 0.2-0.4 micrometre surface roughness, though this should be specified per application, optical-grade polishing reaching Ra 0.05 micrometre for reflector prototypes. Tight tolerances are referenced but not quantified; typical CNC brass prototyping achieves +/- 0.025mm on critical dimensions, with wire EDM holding +/- 0.005mm for fine features. The supplier's sheet metal and machining integration allows hybrid fabrication for complex geometries.

Buyers include automotive tier suppliers validating thermal management components, electronics manufacturers prototyping heat sinks and bus bars, and industrial OEMs testing fit-and-function before tooling investment. Shenzhen Ruitai's location in Guangdong Province positions it within China's principal precision manufacturing cluster, with access to Shenzhen and Guangzhou logistics hubs. The source description references rapid production services and complex parts without expensive tooling, implying bridge production quantities between prototype and full-scale manufacture. Buyers should confirm minimum order quantities, typical lead times for 10-unit versus 100-unit runs, and whether the polished finish is achieved by mechanical polishing, electropolishing, or vapour polishing, as each affects dimensional stability and cost structure differently.

Shenzhen Ruitai Mold Technology Co., Ltd is located at 1103 Room, Tianyue Building, Zhongxin Road No. 110, Shajing, Guangzhou, Guangdong Province, China (postal code 518104), with operations focused on rapid prototyping and small-batch precision manufacturing. The supplier holds harbor-tier trust classification. Response metrics show 0.00% response rate and zero average response hours on record, indicating potential data gap or recent listing status rather than confirmed trading history. No factory audit, ISO certification, or specific quality accreditation is stated in the available profile.

The company's technical description emphasises sheet metal and CNC machining integration with rapid turnaround, serving clients needing functional prototypes without production tooling investment. Notably absent are: stated year of establishment, workforce size, machine count or type, annual revenue, named clients, or specific export experience. The Guangzhou address (rather than Shenzhen, despite the company name) may reflect administrative headquarters versus production facility location. Buyers should verify actual machining capacity, in-house versus subcontracted processes, and quality control equipment (CMM, surface roughness tester, etc.) through direct enquiry and, where possible, factory visit or video audit before committing to precision component orders.
