Custom Aluminum Busbar

Engineering-first, drawing-based aluminum busbars for EV battery systems, energy storage, power electronics, charging equipment, switchgear, and industrial power distribution. Manufactured in Dongguan, Guangdong, China.

BusbarMFG starts with your drawing and application requirements. Our engineering review covers material selection, thickness, insulation, plating, bends, holes, interfaces, and connection methods specific to aluminum. Programs commonly begin with prototypes or validation batches and progress into repeat production as requirements are confirmed.

• Drawing confidentiality and technical review first
• Prototypes, validation, and gradual volume ramp
• Project-specific manufacturability and capability confirmation

Aluminum busbars are often selected where weight and cost tradeoffs are important while maintaining high-current performance.

• Weight and cost: Aluminum can lower system mass and material cost compared to copper, with cross-section adjusted to meet current and thermal targets.
• Thermal and electrical design: Conductor sizing, temperature rise, and mounting for heat dissipation are reviewed against your application.
• Interfaces and joints: Contact resistance, surface preparation, and plating/transition strategies are evaluated to support reliable bolted or clamped joints.
• Corrosion management: Finishes, insulation, and joint design can help mitigate galvanic effects in mixed-metal assemblies.

BusbarMFG produces drawing-based aluminum busbars and related high-current interconnect components for compact, repeatable electrical assemblies.

• Solid and formed aluminum busbars made to print
• Battery busbars and interconnects for EV and ESS modules and packs
• Insulated aluminum busbars: heat-shrink, coated, sleeved, or other insulation options (confirmed per project)
• Custom busbar assemblies: holes, bends, offsets, interfaces, and connection features to match your design
• Transition and interface solutions for aluminum-to-copper connections (project-specific review required)

Note: Specialized processes such as plating on aluminum, welding, overmolding, CCS-integrated assemblies, and similar features are reviewed against the actual project and confirmed capability before they are represented as available for production.

• EV and mobility: module and pack interconnects, positive/negative busbars, contactor and fuse links
• Energy storage systems: rack-level DC distribution, container-level busbars, battery cabinet links
• Power electronics: inverter DC link busbars, PCS and UPS DC bus, rectifiers, power supplies
• Charging equipment: DC fast charger busbars, power distribution links
• Switchgear and industrial power: distribution panels, transformer connections, motor drives, control cabinets

Our engineering team reviews your aluminum busbar design for manufacturability and assembly performance.

• Material selection: common conductor-grade aluminum options (e.g., 1xxx and related grades) confirmed per project
• Thickness and cross-section: sized to meet current, thermal, and packaging requirements
• Bends and forming: inside radius, edge condition, and flatness considerations to meet assembly needs
• Holes and interfaces: hole sizing, slots, pads, threaded inserts or studs (if specified), and joint surface preparation
• Surface finish and plating: tin or other finishes for joint reliability (available options confirmed during technical review)
• Insulation: heat-shrink, coatings, sleeves, or laminated dielectrics reviewed for creepage, clearance, and assembly approach
• Assembly methods: bolted joints, clamped interfaces, and designated weld lands if required by the customer’s process (capability confirmed per project)

If you are evaluating a copper-to-aluminum redesign, we can support the engineering tradeoffs:

• Conductor area adjustments to meet equivalent resistance and temperature rise
• Joint design and plating or transition strategies to manage mixed-metal interfaces
• Insulation and creepage/clearance in tighter packaging
• Busbar geometry optimization for assembly repeatability and routing
• Risk and build-option review from prototype through validation

For an efficient technical review, please provide:

• 2D drawings and/or 3D models
• Material, plating/finish, and insulation requirements
• Quantity plan (prototype, validation, and potential production)
• Application description (EV, ESS, inverter, charger, switchgear, etc.)
• Target date or project timeline

We use this information to assess manufacturability and prepare an engineering quotation. BusbarMFG does not publish unverified certifications, equipment lists, tolerances, lead times, production capacity, or customer claims. Project-specific requirements are confirmed during technical review.

• Engineering review with DFM feedback specific to aluminum busbars
• Feasible build options and identified risks for your application
• Prototype and validation path aligned to your program milestones
• Dimensional consistency, insulation and plating quality focus
• Delivery transparency and program support from prototype toward repeat production
