Advantage of Cold forging heatsink

Compared with other processes, cold forging has unique advantages:

1. Good mechanical strength

2. The surface of the finished mold is beautiful

3. High precision die forming

4. Cost advantage and high material utilization

       The maximum height ratio of fins for general aluminum extrusion tooling is 20, and the cold forging process can be 50 times higher, which has unique advantages.
