Cold forging is a variety of bulk forming processes below the recrystallization temperature of the metal.
Its advantage is that the heat dissipation FIN height can reach more than 50mm, the thickness of 1mm is the following, it can get the maximum heat dissipation area in the same volume, and it is easy to get good dimensional accuracy and surface finish.
But when forging, cooling due to plastic flow will produce necking, fin thickness, easy to have highly uneven situation, thereby affecting the cooling efficiency.
Because of the low plasticity of metal, it is easy to crack and deformation resistance.
Need tons (500 tons) of the forging machinery, so the processing cost is high.
