A Machined Heatsink is an ideal choice for smaller production requirements as there are no Non Recurring Engineering charges (NRE). With highly versatile machining capabilities, Radian Thermal Products provides high precision heatsinks with complex features, contours, cut-outs and through-holes. Combined with a full range of finishing we are your reliable source for quality, affordable machined heatsinks. Machined heatsinks are typically made from Aluminum 6061 or Copper C1100, and quick turn prototyping is available. Although larger designs are possible, typical limits are typically 20 fins – 1.2” high.
Machined Heatsink Examples
In this example a machined heatsink was rapidly designed and manufactured. The customer also wanted to use corporate colors in the coating.
In this example a standard heatsink was machined so that it became a custom part..
In this example a copper heatsink was machined as a platefin then cross cuts were added.
In this example an extruded heatsink was machined so that it could fit an assembly. After the machining the part was anodized.
