Precision Stamped Copper Conductive Busbar

These irregularly shaped metal components, featuring stepped bends and multi-hole layouts, typically serve as conductive busbars in electrical equipment or battery modules. The structure includes mounting flanges for bolt fastening and extended conductive arms, designed to achieve low-impedance connections in high-current transmission paths. Their specific geometry adapts to wiring routes in confined spaces, making them widely used in new energy vehicles, energy storage systems, and industrial power supplies.

The manufacturing process strictly controls springback after multiple bending operations and the relative positional accuracy of holes to ensure a tight fit with terminal blocks during assembly, preventing overheating caused by insufficient contact area. To address stress-induced deformation common in copper stamping, our production line utilizes high-speed presses from brands like YAMADA and KYORI with 0.005mm precision, paired with precision progressive dies for continuous operation. This effectively ensures dimensional consistency and flatness requirements for bulk deliveries.

Supported by dual IATF16949 and ISO9001 certification systems, our factory offers integrated delivery capabilities from mold development to precision stamping. We support processing of high-conductivity materials such as red copper, brass, and phosphor bronze, and can provide surface treatments like silver, tin, or nickel plating to meet corrosion resistance and low contact resistance requirements. Key hole diameters and contours are fully inspected using Mitutoyo vision measuring instruments. Quotations are evaluated based on specific 3D drawings, material grades, plating specifications, and expected order volumes.
