Precision CNC Machining for New Energy | EV Battery & Renewable Energy Parts

PROFIT has extensive experience machining components for EV battery systems and energy storage applications. We manufacture battery enclosures from aluminum with tight flatness tolerances for proper cell cooling, cooling plates with complex internal channel geometries for thermal management, copper busbars with precision-machined contact surfaces for efficient power distribution, and high-voltage electrical enclosures. These components require chip-free machining to prevent short circuits, strict FOD control, and precise dimensional accuracy for reliable assembly. Our 5-axis DMG MORI centers and CMM inspection capability ensure every part meets the demanding requirements of modern energy storage systems.

We machine a comprehensive range of materials critical to new energy applications. Our capabilities include aluminum 6061 and 7075 for lightweight battery enclosures and heat sinks, copper C110 and C101 for busbars and electrical connectors with high conductivity, stainless steel 304 and 316L for corrosion-resistant structural components, titanium Grade 2 for fuel cell components, and engineering plastics including PEEK for electrical insulation, PTFE for sealing applications, and nylon for cable management components. All materials are sourced with full mill test reports and material certifications for traceability.

Yes. PROFIT supports the full product development cycle for new energy projects from rapid prototyping to high-volume production. For design validation and pilot run components, we offer accelerated turnaround of 3 to 5 business days with DFM feedback within 24 hours. Once designs are finalized for production, low-to-medium volumes ship within 7 to 10 days, while high-volume production runs for established new energy products execute within 15 to 25 business days. Our capacity across DMG MORI 5-axis, DOOSAN turning centers, and TSUGAMI Swiss machines allows us to scale efficiently as your project moves from development to production.

Thermal management components such as battery cooling plates and heat sinks require exceptional precision to function correctly. PROFIT employs strict process controls including flatness verification within ±0.03mm across the full plate surface, CMM inspection of all fluid channel dimensions and locations, surface finish measurement to ensure proper thermal interface contact, and pressure testing where required for sealed cooling channels. Our quality team documents every critical dimension with inspection reports included in each shipment. For production volumes, we implement SPC monitoring to maintain consistent quality across all parts.

Yes. PROFIT has extensive experience machining copper busbars, terminals, and electrical connectors for high-current new energy applications. We machine C110 and C101 copper with precision-machined contact surfaces, chamfered edges for safe assembly, and drilled and tapped mounting holes to print specifications. Copper machining requires specific techniques to manage material softness and achieve burr-free results. Our team understands the conductivity requirements and dimensional precision needed for busbars used in EV battery packs, energy storage systems, and power distribution assemblies.

Every shipment includes a Certificate of Compliance (CoC) with dimensional inspection reports covering all critical features. Additional documentation available upon request: Material Certificates with mill test reports, First Article Inspection (FAI) reports, CMM inspection reports, surface finish measurement reports, and conductivity testing documentation for electrical components. Our quality team maintains complete traceability records linking each production lot to raw material certifications and inspection results, ensuring full documentation for your quality management system.
