Import Custom Aluminum Round Heat Sink — Buy in Bulk from Supplier in China

This custom aluminum round heat sink is precision-engineered for thermal management in electronic assemblies, with a focus on high-surface-area designs for passive or forced-air cooling. The unit is produced using aluminum die casting, a process the supplier specializes in, and can be tailored to specific diameter, fin density, and mounting configurations to match OEM requirements. The base material is aluminum alloy, selected for its thermal conductivity and lightweight properties.

Typical industry variants for this category include 6061 or 6063 aluminum grades, which offer a balance of conductivity, machinability, and corrosion resistance. Fin configurations often range from 20 to 50 fins per inch, with fin heights between 10 mm and 50 mm standard for most applications. Surface treatments such as anodizing or chromate conversion are common to enhance durability and heat dissipation, though the supplier’s exact finish options should be confirmed.

These heat sinks are primarily used in power electronics, LED lighting, and automotive control modules where reliable thermal dissipation is critical. Buyers in these sectors typically source in bulk, with MOQs and packaging details negotiated directly. The supplier’s experience in exporting to Japan, South Korea, and Europe suggests familiarity with international standards for dimensional tolerances and material traceability.

Dalian Oukerui Industrial Co., Ltd. is based in the Development Zone of Dalian, Liaoning Province, China, with a facility covering 5000 square meters. Established in 2011, the company began in the mold industry and has since expanded into integrated design, production, and transformation services. It operates over 30 sets of advanced production equipment and employs 30 skilled workers, indicating a mid-scale operation with in-house machining capabilities.

The supplier specializes in aluminum and zinc alloy die casting, with a product portfolio that includes precision parts for clients such as Toshiba, Canon, and Ryobi. Its export markets span Japan, South Korea, and Europe, demonstrating experience with international quality and logistics standards. The company also offers precision machining services, which complements its heat sink production by allowing for post-casting modifications like tapping, drilling, or surface finishing.
