Extruded heat sinks are crafted using a specialized process, pushing material through a die for intricate cross-sections. We employ the high thermal conductivity aluminum alloy A6063 at FM, chosen for its unique properties despite being challenging to work with. Ideal for high-volume production due to lower non-recurring engineering (NRE) costs, molds are made through wire EDM with a lead time of 4-6 weeks. This method proves most economical when post-machining is unnecessary, minimizing stress-related distortion. Extruded heatsinks, with thin fins and an 8:1 aspect ratio, optimize performance, exemplified by the Platefin extruded heat sink designed for efficient natural convection heat dissipation.
