Precision Extrusion Molding Aluminum Heat Sink with 6061/6063 High-Purity Alloy and CNC Precision Milling

Our aluminum heat sink core utilizes precision extrusion molding technology with specialized custom molds and high-precision extrusion equipment. Manufactured from 6061/6063 high-purity aluminum alloy ingots as a single integrated piece, this process eliminates the need for subsequent complex processes like splicing and welding.

• Eliminates thermal conduction faults and loose structures found in traditional spliced radiators
