Chengdacai supplies thermally efficient aluminum extrusions, housings and fabricated components for solar, energy storage, power conversion, charging and electronic systems. Designs can combine heat dissipation, protection and assembly features in one profile.
Typical Applications
- Inverter, power-supply and control-system heatsinks
- Battery trays, energy-storage racks and protective enclosures
- Solar mounting rails, clamps and structural supports
- LED, telecom and industrial-electronics housings
Alloy, Temper and Finish Options
| Alloys | 6063 for thin fins, heat-transfer profiles and anodized housings; 6061 or 6082 for higher-strength supports, trays and machined interfaces. |
|---|---|
| Finishes & Processing | Anodizing, powder coating, passivation-compatible preparation, precision CNC machining and controlled flatness for thermal interfaces. |
Engineering and Procurement Notes
Specify heat load, airflow, thermal interface area, ingress-protection target, electrical isolation needs, corrosion environment and sealing geometry. Fin height and spacing should be reviewed for extrusion feasibility.
From Drawing Review to Production
- Share drawings, specifications, annual volume and application conditions.
- We review extrusion feasibility, alloy, tolerances, tooling and secondary operations.
- Samples are inspected and approved before production release.
- Production parts are finished, checked and export-packed to the agreed plan.

Frequently Asked Questions
Why is aluminum used for electronic thermal management?
Aluminum combines useful thermal conductivity, low mass, corrosion resistance and the ability to extrude complex fins and mounting features.
Can heatsinks be supplied machined and anodized?
Yes. We can machine mounting faces and holes, control flatness and apply natural, black or custom anodized finishes.
What should be included in a battery enclosure RFQ?
Include the assembly drawing, load cases, sealing concept, thermal requirements, joining method, finish, tolerances and validation standards.
