1.About the cold forging
A Forged heatsink is manufactured using a modification of this process called cold forging. Cold forging uses high pressure and low temperature to ensure that no air bubbles, or other impurities are trapped in the material. This improves the thermal properties of the heatsink, and increases the density of the material.

Cold forging uses high pressure and low temperature to ensure that no air bubbles, or other impurities are trapped in the material. This improves the thermal properties of the heatsink, and increases the density of the material. Radian Thermal Products utilizes special open die tooling and intense pressure to produces high precision heatsinks with high aspect ratios. A Forged heatsink is typically manufactured one part at a time, and can be can be made from AL 6063 or C1100. Aspect ratio up to 35:1 are feasible, and no draft angles required on fins. Fins can be round, elliptical, straight or any combination on the same part.
2.About the cold forging process
Cold forging uses a displacement process to shape the material into the desired shape. Compressive force squeezes the metal between a punch and die at room temperature until the material conforms to the die's contours. Cold forging techniques include rolling, pressing, drawing, spinning, heading, and extruding
3.The advantage of cold forging heat sink
The cold forged heat sink is widely used in the heat dissipation of LED lamps and has the following advantages:
(1) The price of cold forging die is not high, which can effectively control the cost;
(2) High production capacity, suitable for mass production;
(3) The mold production cycle is relatively short, usually 10 to 15 days;
(4) One-time molding, the heat dissipation performance of cold forging heatsink is consistent with the heat dissipation performance of the material, and the post-processing procedures are few and simple.
(5)The major advantages of cold forging are close dimensional tolerances, good surface finish quality, and the use of lower cost materials to obtain the required strength by work hardening without requiring heat treatment.
4.Heatsink Surface Area
Increased surface area of the heat sink will yield lower thermal resistance and better component cooling, but only if boundary layer is not formed and fins close proximity do not prohibit flow of air.
When designing extruded part, fins must be tapered so that the aluminium alloy will pass through the tool without breaking it. The number of fins in an extrusion limited by strength of the die set and the size of the extrusion. These restrictions will have impact on the surface area.
Forged fins require lesser taper for extraction from the tool, allowing for more fins per given heat sink size. Heat sink fins can also be formed in to elliptical shape if required.
