Though aluminum extruded heat sinks have long been mainstream as cooling devices, designers have tended to use ready-made designs to save on cost and improve delivery times. The product line of "saisink" features revolutionary heat sinks whose size and shape can be customized to match the designs of equipment in which they will be fitted. The same technology that supports the bending and processing of thin sheet metal allowed the manufacturer to build without using molds and create various lightweight fins at low initial cost. Designers now can develop their equipment without having to compromise over a single part.
