Heat Sinks
Air-cooled heat sinks in every manufacturing route.
A heat sink increases the surface area available to move heat from a hot device into moving air. Different fin geometries and manufacturing processes give very different trade-offs in thermal performance, weight and cost. Speak to our heat sink specialist and we'll help you pick the right one.
The product range
A closer look at the materials we supply.
One-piece skived construction with zero fin-to-base interface resistance.
Explore
Ultra-high aspect ratio fins for maximum thermal performance in a compact envelope.
Explore
Pin-fin and radial geometries formed under pressure — great for high-volume programmes.
Explore
Continuous folded fin bonded to a base — thin, light and thermally efficient.
Explore
Precision-machined bespoke designs for prototypes and specialist applications.
ExploreSkived
Fins skived directly from a solid billet — no interface resistance between base and fins.
Zipper Fin
Very high fin density and aspect ratio — outstanding thermal performance for high-power applications.
Cold Forged
Pin-fin and complex geometries formed under pressure — high performance at high volume, low unit cost.
Folded Fin
Bonded folded copper or aluminium fins for optimised air-side performance in a slim envelope.
CNC Machined
Precision-machined prototypes and low-volume production for bespoke geometries and tight tolerances.
Bespoke assemblies
Heat sinks combined with heat pipes, vapour chambers or fans as a complete cooling module.
