Manufacturing Process
Cold forging is a manufacturing process in which the aluminum or copper heat sink is formed by using localized compressed forces. Fin arrays are formed by forcing raw material into a molding die by a punch. The process ensures that no air bubbles, porosity or any other impurities are trapped within the material and thus produces exceptionally high quality products.
