Extruded Heat Sinks Manufacturers & Suppliers
What is Extruded Heat Sinks
An extruded heat sink is an aluminum alloy profile (e.g., 6063/6061) formed by forcing heated metal through a die, creating continuous fins with 8-15 fins/cm² density. It balances thermal efficiency and affordability, commonly used in LED lighting, consumer electronics, and industrial controllers.
Mass Production Efficiency
30-50% lower material cost vs. machined sinks.
Single mold supports 100K+ units, ideal for bulk orders.
Design Versatility
Complex cross-sections (e.g., asymmetric fins, custom bases).
Length customization (50mm–3m standard range).
