A method for producing a heat sink includes extruding a first material in a second material, and cut into a billet. The second material is removed from the billet to produce a base and a plurality of fins. The second material is removed from the billet by placing the billet into a chemical bath. The heat sink is rinsed to remove chemical residue from the heat sink. Mounting holes are stamped into the base, and a mounting surface is ground on the heat sink. Another method for producing a heat sink includes ramming fins into a base. The base is heated prior to the entry of the fins. The base is also provided with dimples to accept entry of the fins.
