Cold forged heat sink is a type of heat sink manufactured using metal cold forging technology, cold forging process is usually used to manufacture high-strength and high-precision parts. Compared to traditional hot forging processes, cold forging processes are carried out at room temperature, without the need to heat metal materials to high temperatures. The parts produced have higher density, higher strength, better wear resistance, and better surface quality.

The manufacturing process of cold forging heat sink mainly includes the following aspects:
1. Principle: The manufacturing process of cold forging heat sinks involves cold forging metal plates or billets at room temperature, and plastic deformation of the material is achieved under conditions such as cold and hot alternation, stretching, and compression to obtain the desired shape of the heat dissipation fins.
2. Equipment: The processing equipment for cold forging heat sinks mainly includes hydraulic cold forging machines, contour grinding machines, cutting machines, etc. Among them, hydraulic cold forging machine is the most important equipment in the production process of cold forging heat sink, used to process metal billets into the shape of heat sink.
3. Process flow: The process of cold forged heat sink usually includes the following steps: raw material selection, cutting, cold forging forming, contour processing, and testing. Among them, cold forging forming is the core step of the entire processing process, the metal materials are cut off and sent into the mold cavity of the cold forging machine. Under the action of strong pressure and a certain speed, the metal billet is forced to produce plastic deformation in the mold cavity, so as to become the required shape, size and mechanical properties of the heat sink.
4. Annealing treatment: Anneal the cold forged heat sink to achieve the desired structural state. The annealing temperature, time, and cooling method should be accurately controlled based on the type and requirements of the material.
5. Surface treatment: Perform surface treatment on the annealed heat sink, such as polishing, oxidation, etc., to increase its corrosion resistance and aesthetics.
6. Finished product inspection: Conduct quality inspection on the manufactured heat sink, including checking dimensions, appearance, weight, material composition, and physical properties.
