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

This custom aluminum heat sink is precision-engineered for thermal management in electronics, automotive, and industrial applications. The supplier, Dalian Oukerui Industrial Co., Ltd., specializes in die-cast aluminum components with designs tailored to dissipate heat from high-power devices. The unit is produced using aluminum die casting, a process that ensures consistent wall thickness and fine surface finish for optimal heat transfer.

The heat sink is typically manufactured from aluminum alloys such as A380 or A383, known for their thermal conductivity and lightweight properties. Standard finishes include anodizing or powder coating to enhance corrosion resistance and aesthetic appeal. The design often incorporates fins, pins, or grooves to maximize surface area, with typical tolerances for die-cast parts ranging from +/-0.1mm to +/-0.5mm depending on complexity. Industry standards for such components often reference ASTM B85 for alloy specifications and ISO 2768 for general tolerances.

Importers in electronics manufacturing, LED lighting, and power systems rely on these heat sinks to maintain operational temperatures in compact or high-performance assemblies. The supplier exports to Japan, South Korea, and Europe, with packaging typically including individual poly bags and reinforced cartons for bulk shipments. Buyers should confirm customization options for fin density, mounting holes, and thermal interface materials to match their specific cooling requirements.

Dalian Oukerui Industrial Co., Ltd. was established in 2011 and operates from a 5000m² facility in Dalian, Liaoning Province. The company began in the mold industry and has since expanded to become a specialist in aluminum and zinc alloy die casting, with over 30 sets of advanced production equipment and a team of 30 skilled employees. Its focus is on integrating design, production, and transformation services for precision components.

The supplier has a proven track record of exporting aluminum die-cast parts to international markets, including Japan, South Korea, and Europe. Its client base includes recognized names such as Toshiba, Canon, Ryobi, and Dalian Machine Tool Group, reflecting its capability to meet the demands of high-precision industries. The company also offers precision machining services to complement its die-casting operations, catering to buyers requiring tailored solutions.
