HAIFEI copper foil bonding machine is designed for multilayer copper foil bonding, laminated copper busbars, EV battery connectors, energy storage systems, and high-current electrical components. The machine uses controlled heat, pressure, and holding time to create a solid-state copper-to-copper bond without solder or filler metal.
Haifei can customize the bonding pressure, heating platen size, fixture, PLC control system, cooling method, and automation level according to the customer's copper foil thickness, stack quantity, bonding area, and production capacity.

Solving Critical Industry Challenges
| Challenge | Our Solution | Your Benefit | |
| 1 | Soldered or bolted busbars have higher electrical resistance, causing energy loss (heat) and reducing system efficiency and range in EVs. | Solid-state diffusion bonding with 100% metal purity at the joint. | Maximize power transfer efficiency, improve system performance, and reduce thermal management burdens. |
| 2 | Mechanical and thermal stress cause traditional connections to fail, leading to system downtime and safety risks. | A joint with strength and thermal properties identical to solid copper. | Achieve unparalleled product reliability and safety, reducing warranty claims and enhancing brand reputation. |
| 3 | Inconsistent manual processes lead to variable quality, scrap, and difficulty in meeting automotive-grade traceability standards. | Fully automated, recipe-driven process with digital parameter logging. | Guarantee consistent quality, achieve near-zero scrap rates, and generate automatic production records for full traceability (IATF 16949 support). |
