Engineered for Superior Power Distribution
At JUMAI Tech, we manufacture custom copper busbars utilizing high-purity T2/C11000 copper (99.9% pure). Our busbars are critical components for efficient power transmission, offering exceptionally low electrical resistance and excellent thermal management properties.
Whether you need robust rigid connections for heavy industrial machinery or highly flexible braided solutions for the vibration-heavy environments of New Energy Vehicles (NEVs), we have the complete in-house capabilities to punch, bend, plate, and insulate to your exact CAD specifications.

Types of Copper Busbars We Manufacture
We offer three primary categories of busbars, fully customizable in shape, size, and finish to suit your specific spatial, electrical, and mechanical requirements.
Standard Power
Hard / Rigid Busbars
Solid copper bars precision cut, punched, and CNC bent. Ideal for static applications requiring massive current carrying capacity and structural rigidity where vibration is not a primary concern.

High Vibration
Soft / Braided Busbars
Woven from fine copper wires (bare or tinned) with solid cold-pressed terminals. Specifically designed to absorb extreme vibrations, accommodate thermal expansion, and compensate for dynamic misalignments.

Tight Spaces
Laminated Flexible Busbars
Constructed from multiple layers of thin copper foils, firmly press-welded (diffusion welding) at the mounting areas. Offers the exceptional conductivity of solid bars combined with the ability to bend and twist in extremely tight spaces.

Powering the Industries That Move the World
Our precision-engineered copper busbars deliver safe, efficient, and reliable power distribution across demanding industrial applications. From electrification and renewable energy to critical infrastructure, we build solutions designed for performance, durability, and exact application requirements.
Surface Finishes & Insulation Capabilities
We deliver more than raw copper. JUMAI Tech provides fully finished, ready-to-assemble components equipped with required surface protections against oxidation and high-grade electrical insulation for safety.

From Drawing to Delivery
A streamlined, transparent process ensuring your custom components meet exact specifications on time.
1. Drawing Evaluation
Send your 2D/3D CAD files. Our engineers review for manufacturability (DFM) and provide a quote.
2. Rapid Prototyping
We produce physical samples for your team to test fit, form, and electrical function before mass production.
3. Mass Production
Upon approval, we initiate CNC machining, pressing, plating, and insulation processes.
4. QC & Global Shipping
100% inspection for dimensional accuracy and insulation integrity prior to secure global dispatch.
