Extruded heat sinks use an extrusion manufacturing process where material is pushed through a die of the desired cross-section. Extruded heat sinks can have very complex cross-sections and use brittle materials. Extruded parts have an excellent surface finish and are ideal for additional finishes such as anodizing or electroplating.

Extruded heat sinks are suitable for high volume production because of their relatively low NRE. Molds are usually made using wire EDM and mold lead time is usually 4-6 weeks. Most cost-effective when post-machining is not required, as additional CNC machining may relieve stress that can lead to distortion. This can be minimized with special heat treatments to limit failures due to stress. Extruded heatsinks offer thin fins and an approximately 8:1 aspect ratio for optimal heatsink performance.
One of the most common extruded heat sinks is the Platefin extruded heat sink, which extracts heat by natural convection. Extruded plate fin heat sinks use straight fins running the entire length to maximize the surface area of the heat sink. Heatsinks can be additionally machined to form crosscuts with similar effects to elliptical fin heatsinks.
