CNC Machining T2 Purple Copper Connector Parts High Conductivity Corrosion Resistant for Electrical and Electronic Applications

High-Precision Oxygen-Free Copper (OFC) Finished Parts

We specialize in manufacturing high-precision finished parts from C11000/C10100 (Cu ≥ 99.99%) copper, serving major clients in new energy, power connection, thermal management, RF coaxial connectors, and high-end industrial equipment sectors.

Key Manufacturing Processes

● Raw material: High-purity electrolytic tough pitch (ETP) or oxygen-free copper ingots (Cu ≥ 99.99%)
● Melting: Medium-frequency induction furnace under vacuum or protective atmosphere to minimize gas content
● Forming routes: Hot forging/cold heading → Multi-station cold extrusion → Precision CNC turning-milling compound machining → Deburring + ultrasonic cleaning
● Surface finishing: Bright annealing, selective or full-area electroplating (Ag, Au, Sn, Ni) in accordance with IPC-4552/4553 standards
● Dimensional accuracy: Standard tolerance ±0.01 mm; critical features achievable to ±0.005 mm (part-dependent)

Quality Control System

● Operated under full IATF 16949 quality management system
● Incoming material: 100% direct-reading spectrometer composition analysis + hydrogen embrittlement and oxygen content testing
● Outgoing inspection: Conductivity (IACS%), plating thickness (X-Ray), adhesion (bend/thermal shock), salt-spray performance, full dimensional report, and Material Certificate 3.1 with full traceability to ingot batch
● Defect rate performance: DPPM < 50 for key account batches

We focus on delivering repeatable lot-to-lot consistency and fully traceable data rather than marketing slogans. You are welcome to submit drawings or physical samples; we typically complete process review and provide a DFM report and formal quotation within 3–5 working days.
