Import Custom Oem Aluminum Led Lighting Heat Sink — Buy in Bulk from Supplier in China

By Thermal supplies custom extruded aluminum heat sinks designed for LED lighting systems, with base dimensions and fin geometries tailored to client thermal loads. The supplier provides heat sinks manufactured from 6063-T5 aluminum alloy, with thermal conductivity of approximately 201 W/mK, and surface finishes including natural anodized or black anodized options as requested. Dimensions are adjustable per CAD input, with typical fin thicknesses ranging from 0.8mm to 2.0mm and heights up to 80mm, depending on airflow and power density requirements.

The heat sinks are produced via extrusion followed by CNC machining for mounting holes and surface flatness, ensuring tight tolerances of ±0.05mm on critical contact surfaces. Standard surface roughness is Ra 1.6, suitable for direct mounting to LED modules. While the supplier does not specify minimum thermal resistance values, industry-standard performance for similar extruded designs ranges from 0.8 to 2.5 °C/W per watt of dissipation, depending on fin density and airflow. The material is non-corrosive and suitable for indoor and controlled outdoor environments.

These heat sinks serve OEMs in LED lighting, automotive headlamps, and industrial control systems where compact thermal management is critical. Buyers include manufacturers of high-power LED fixtures and lighting integrators requiring custom form factors. Trade terms include FOB Guangdong ports, with packaging in corrugated cartons with foam inserts. MOQ is typically 500 units per design, but sample orders may be accommodated on request. Lead time for custom tooling is 15 to 25 days, followed by 7 to 10 days for production.

By Thermal operates from Dongguan, Guangdong, with a facility focused on aluminum extrusion and precision machining for thermal components. The supplier is verified as a harbor-tier manufacturer with no public data on years in business, workforce size, or revenue. The listing confirms capability in OEM design support and thermal simulation using industry-standard software, but does not list client names, certifications, or production volumes.

The supplier offers free thermal design assistance, indicating engineering resources are available to support custom projects. However, there is no public information regarding ISO certification, environmental compliance, or in-house testing equipment. Response metrics are not available, and the supplier has not provided contact details beyond the factory address. Buyers should request samples and validate performance data directly before placing bulk orders.
