What are One-piece Solid Copper Contacts?
Xiamen Apollo supplies high‑precision One-piece Solid Copper Contacts, integrally formed from high‑conductivity pure copper or oxygen‑free copper. These integral copper contact rivets deliver solid structural strength and stable contact resistance, and meet RoHS and REACH compliance requirements. Widely adopted for switches, relays, industrial motors, communication power supplies, and power tools. We support full custom‑made production according to customer drawings, providing one‑stop procurement service and competitive lead time.
Production Process of Solid Copper Contacts
Raw Material Selection & Pre-treatment
We select high‑purity copper raw materials strictly in accordance with industrial electrical standards. Raw bars are inspected for conductivity, hardness, and surface quality before cutting. Pre‑treatment removes oil stains and surface oxide layers to guarantee consistent forming quality for subsequent procedures.
Precision Integrated Forming
Adopting cold heading and stamping technology, the whole contact is shaped in one forming cycle without secondary riveting assembly. This one‑piece forming method eliminates assembly gaps and internal stress, improving mechanical stability for long‑term switching operations.
Finishing & Surface Optimization
Components go through deburring and dimensional fine finishing. Optional surface treatments include natural passivation, silver plating, and tin plating to enhance anti‑oxidation performance and reduce contact resistance under working conditions.
Full-process Inspection & Packaging
Each batch undergoes dimension checks, appearance inspection, and conductivity sampling test. Qualified parts are packed in anti‑oxidation packaging to avoid surface oxidation during transit and storage.
Material Advantages of Rivet-type Solid Copper Contacts
Electrical Conductivity Advantage
Made of high‑conductivity pure copper or oxygen‑free copper material. The one‑piece integrated structure avoids extra contact interfaces, maintaining low and stable contact resistance during continuous current‑carrying work.
