Extruded Heat Sink Manufacturing Process

What it does

Looking for high-performance extruded heat sinks? Discover the complete manufacturing process from aluminum billet extrusion to custom CNC finishing and surface treatment.

Learn how heat sinks are manufactured, from aluminum extrusion and skiving to CNC machining, cold forging, die casting, and bonded fins. Compare heat sink manufacturing processes, materials, applications, and production methods.

Heat sink manufacturing involves converting thermally conductive materials such as aluminum and copper into heat-dissipation components using processes including extrusion, skiving, CNC machining, cold forging, die casting, and bonded-fin assembly. What are the main steps in the extrusion manufacturing process? What is the maximum aspect ratio for extruded heat sink fins? What is the difference between natural convection and forced convection heat sinks? What tooling costs are involved in custom heat sink extrusion? What is the typical lead time for a custom extruded heat sink profile? How does cross-cutting turn an extrusion into a cross-cut pin fin heat sink? What thermal interface…from kingkametal.com
