Surface Finishing & Protection

Copper and its primary alloys, including brass and bronze, are widely used in electrical, automotive, telecommunications, and industrial applications due to their excellent electrical conductivity, thermal performance, corrosion resistance, and formability. However, precision copper stamping requires extensive manufacturing expertise to address material-specific challenges, including burr formation caused by high ductility, rapid heat transfer during blanking, springback after forming, and increased tool wear when processing higher-strength copper alloys.

With 26 years of precision metal stamping experience, Runyuan combines in-house tool-and-die expertise with advanced hydraulic and mechanical stamping presses to manufacture high-precision Copper Stamping Parts that meet demanding engineering specifications. Through optimized progressive, compound, and single-stage tooling, together with rigorous process control and in-process quality inspection, we consistently produce components with clean sheared edges, excellent surface integrity, reliable dimensional consistency, and precision tolerances of up to ±0.05 mm from prototype development to high-volume production.
