Battery Bracket Parts We Machine
- Module end plates and side plates
- CCS battery cover plates
- Cell support frames and holders
- PACK mounting brackets
- Liquid cooling plate components
- Busbar insulation mounts and fixing seats
Materials & Finishes
Materials: 6061-T6 aluminum (mainstream for lightweight plus structural strength), 6063 and 5052 aluminum available. Key load-bearing areas get reinforcing ribs and local thickening. Parts can mate with liquid cooling plates for thermal management.
Finishes: anodizing insulation treatment (critical for battery pack electrical isolation), nickel plating, and chromate conversion coating per automotive requirements.
Tolerances & Inspection
Tolerance ±0.005mm; flatness ≤0.005mm on sealing and cooling-plate mating surfaces (directly affects PACK assembly and sealing). Every bracket is inspected on CMM with full dimensional reports, and liquid cooling plate mating faces receive dedicated flatness control for sealing and thermal conductivity.
Quality System
ISO 9001:2015 certified quality management with PPAP (Production Part Approval Process) documentation support for automotive customers.
Applications
CHX Metal battery brackets and structural parts are used in passenger EV battery packs, commercial vehicle battery enclosures, grid-scale energy storage systems (ESS) and battery modules for robotics and automated guided vehicles. Typical projects range from prototype validation batches to mass production of hundreds of thousands of pieces per month, with dedicated production planning for automotive launch schedules.
For energy storage PACK manufacturers, we machine brackets that mate with liquid cooling plates, where flatness and hole-position accuracy directly determine sealing performance and thermal conductivity. For module-level assemblies, our end plates and side plates maintain consistent dimensional stability across production runs, verified by SPC process control.
Packaging & Delivery
Parts are cleaned, protected with anti-scratch film or VCI packaging as required, and packed in customized trays to prevent deformation during international shipping. Prototype lead time 3-7 days; production 7-15 days; surface treatment adds 5-10 days. DFM feedback on RFQs within 24 hours, global shipping with full traceable inspection records.
Design for Manufacturing (DFM) Support
Send your STEP, IGES or SolidWorks files and our engineering team reviews wall thickness, corner radii, tolerance stack-up and finish selection before quoting. For battery brackets we commonly recommend adjustments that reduce machining time and cost without sacrificing structural integrity, for example consolidating multiple brackets into one machined part, or switching from fully machined plates to extruded profiles with machined critical faces. Every RFQ receives a documented DFM report alongside the quotation, covering material options, tolerance feasibility and recommended inspection points for battery pack assembly.

These are representative examples; we regularly take on custom geometries outside this list. Send your drawing for a feasibility check.
Our Machining Capability
Production runs on 3-axis and 5-axis vertical machining centers, CNC lathes, and Swiss-type automatic lathes. Fixtures are designed in-house for repeatable clamping, and programs are simulated before cutting to protect tight tolerances. Every order ships with in-process inspection records. Our CMM verifies critical dimensions against your drawing on first article, at batch start, and at final release. Material certificates (EN 10204 3.1) and full dimensional reports come standard; PPAP and FAIR documentation are available on request for automotive and industrial programs.
Surface Finishing Options
Available finishes include Type II and Type III anodizing (clear, black, and custom colors), sandblasting, wire drawing, laser engraving and silk-screen marking, zinc and nickel plating, passivation, and black oxide. Cosmetic parts are inspected under standardized lighting with defined surface criteria.
MOQ, Lead Time & Packaging
Standard lead time is 3-7 days for prototypes and 7-15 days for production batches, with surface treatment adding 5-10 days. Parts are cleaned, protected against corrosion and scratching, and packed in customized trays or EPE foam for international shipping. DFM feedback on RFQs is returned within 24 hours.
Why Choose CHX Metal
One supplier from drawing to finished part: milling, turning, 5-axis and Swiss-type machining are all in-house, together with anodizing, plating, laser marking, and silk-screen coordination. You get one accountable partner instead of a chain of subcontractors.
