Our impact aluminum extrusion heat sinks use a large, high-tech vertical extrusion press to produce them. This method, also known as precision forging, allows us to create complex aluminum extrusion profiles that no other company can replicate.
Precision forging uses special open die tooling and intense pressure to form thin-sectioned, high precision heatsinks. This allows us to achieve high aspect ratios with the ability to accommodate fin thicknesses as thin as 0.020” and fin heights over 1” tall for the same base size. Copper inserts may be incorporated into the base for more effective heat spreading.
We have over 20 years of experience with forged heat sinks and use premium grade aluminum billet cast in our own facility. This allows us to create aluminum shapes that our competition–who uses commercial grade aluminum billet–can’t match. When we put these custom aluminum profiles to work, they create superior quality impact extrusion heat sinks that meet your precise requirements.
