Products Description
Copper Terminal Ag-Plated for HVDC Contactor is a key conductive component used in high-voltage DC contactor systems for new energy vehicles. This product is typically formed by stamping high-conductivity copper and integrating silver contact structures through a riveting process. In some applications, the surface is further treated with silver or tin plating to further enhance conductivity, oxidation resistance, and long-term stability.
Integrated Precision Manufacturing Process
High-Precision Stamping and Forming
Utilizing multi-station progressive dies, all processes including blanking, punching, bending, and stamping are completed in one go on a high-speed press. Key parts of the die are made of cemented carbide to ensure dimensional consistency in mass production for Copper Contact Terminal for EV HVDC Relay Contactor (critical dimensional tolerance ±0.03mm). For large, thick copper parts (up to 3-4mm), a servo press is used for precision bending, controlling springback.
Precision Riveting Technology
Connecting silver alloy contacts to the copper terminal body. We employ high-speed precision rotary riveting or resistance welding technology. Rotary riveting forms a cold-forged bond through rotational rolling, eliminating the heat-affected zone and resulting in high connection strength; resistance welding forms a metallurgical bond with even lower contact resistance for the Copper Stamping Terminal for EV Charging Relay. A force-displacement monitoring system ensures consistent quality at each riveting point.
Detailed Display and Design Advantages
Dimensional Accuracy
Utilizing integrated CAD/CAE design, precise alignment of the in-mold welding/riveting stations is achieved, ensuring that each Fixed Copper Terminal for New Energy High Voltage Relay accurately matches the mounting holes of the HVDC contactor.
Surface Flatness
Through a unique elastic demolding system, the flatness of the Custom Copper Stamping for EV Relay surface reaches 0.05mm/100mm, ensuring uniformity of electrical connections.
Arrow Resistance
During high-voltage DC switching, the low melting point of the silver plating instantly forms a molten layer, absorbing arc energy and reducing wear at the Copper Stamping Terminal for EV Charging Relay.
Quality Control and Certification
Core Certifications
The Copper Contact Terminal for EV HVDC Relay Contactor has been certified by IATF16949 (Automotive Industry Quality Management System) and ISO9001 (Quality Management System).
Waste Recycling
The immediate copper waste recycling system achieves a material utilization rate of over 85%, complying with environmentally friendly production standards for the Copper Stamping Terminal for EV Charging Relay.
Environmental Compliance
Cyanide-free silver plating process and a closed-loop wastewater treatment system ensure that Custom Copper Stamping for EV Relay complies with RoHS and REACH environmental standards.
