Aluminum Solutions for Renewable Energy & Electronics

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.

Reference component	Custom LED Aluminum Heat Sink Extrusion
Key review points	Fin geometry, thermal interface area, airflow conditions, machining access and surface-finish requirements.
Information for quotation	2D or 3D drawing, heat source or thermal interface requirements, quantity, critical dimensions, machining and finish requirements.

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.
