die-cast-heatsinksThis paper helps define basic characteristics of Die Cast Heatsinks. DOWNLOAD AS PDF What is Die Casting? Die casting is the process of forcing molten metal under high pressure into a molded cavity. The molded cavity is created using a hardened tool steel die which is carefully machined into a pre-designed shape.  The casting equipment and the metal dies represent large capital cost which tend to limit the process to high volume production applications.  Radian Die-Cast Heatsinks...
