Forged Heat Sinks

Pressed -forged

Forged heat Sinks

Both fins/pins and base are made from a single piece of metal by forging it into the form by high pressure.

Forged heat sinks can be made with thin round pins or thin fins and high density geometries while benefiting from the thermal conductivity of a uniform piece of metal (no impedance from bonding). 

Pin Fin advantages: Erecting a forest of pins from a flat base is a popular way to maximize surface area; they work best when air flows axially along the pins.

COLD FORGED HEAT SINKS

An ideal solution for mass production of high performance heat dissipation requirements.
The production process for cold forged heat sink requires no machining, cutting, or welding, making it more cost effective than extruded or bonded-fin heat sinks.
A variety of heat sink fin shapes can be produced, including pin fin heat sinks, plate fin heat sinks, air foil fin heat sinks, round fin heat sinks, and square fin heat sinks.
Cold forged heatsinks are used to dissipate heat in high powered electronics, multi-chip modules, and in other similar applications.
