Precision Forging

Our Precision Forging process involves aluminum or copper that is pressed, pounded or squeezed under great pressure into high strength parts known as forging die. The process is normally (but not always) performed at a high temperature by preheating the metal before it is worked. This process can produce any fin type and high aspect ratio heatsink. Forged parts generally require further processing to produce the finished part.

  • Fins can be round, elliptical, straight or any combination
  • Heat sinks can be made from aluminum or copper alloy
  • Thin walls of .020” with aspect ratios up to 35:1 being feasible
  • Higher tooling cost than extrusion, but unit price is generally competitive with most of the processes
  • Heat sinks of the same footprint with various heights require only one set of forging die
