500pcs Copper Pin Fin Heatsink Demand From The Local Customer

     Today , Sinda Thermal production team got the first 10pcs copper pin fin heatsink finished by cold forging process, we will have the FAI dimension check to make sure the hard tooling is okay for production.The heatsink material is copper, with round fin design. It's for LED heat disspation.The integrated structure provide the better thermal performance and higher reliability.

     The forging process is formed by heating the aluminum block to the yield point and filling the die with high pressure. Its advantage is that the fin height can reach more than 50mm and the thickness is less than 1mm, the maximum heat dissipation area can be obtained in the same volume, and it is easy to obtain good dimensional accuracy and surface finish. However, during forging, due to the necking phenomenon during cooling plastic rheology, the heat sink is easy to have uneven thickness and height, which affects the heat dissipation efficiency. Due to the low plasticity of metal, it is easy to crack during deformation and large deformation resistance, large ton (more than 500 tons) forging machinery is required, and the high cost of equipment and die leads to high product cost. And because of the high cost of equipment and molds, the cost is too high unless for high volume mass production.
