OEM/ODM Extruded Aluminum Heat Sink
Depending on the shape and material, heat sinks can be made using a variety of manufacturing methods. The most common and inexpensive methods include extrusion, forging, casting, and stamping. Other costly methods include CNC machining, turning and forging. Like our product: Aluminum CNC machined and extruded heat sink for cooling. This one is produced by extrusion and CNC machined processes, which can make the cost much better.
Extrusion is the most cost-effective process for manufacturing finned heat sinks. But further secondary operations add to the overall cost.
Cold forging is a highly precise process that can produce round and oval pin radiators. Due to the high pressure and low temperature, forged heat sinks have very good micro structural integrity.
Casting, especially die casting, can produce heat sinks with complex geometries. But the materials that can be cast have lower thermal conductivity than those used in extrusion and forging.
Stamping is often used to make tall heatsinks that require heat pipes to pass through the fins.
Turning and swaging can be used to manufacture special radiators. But because they are expensive, they are only used in applications where cost is not a sensitive factor.
CNC machining is a versatile manufacturing method that can produce radiators with the most complex geometries or parts that require urgent deliveries, but cost is often a disadvantage.
