Closed-Die Drop Forging Explained
Closed-die drop forging is a process that hammers heated steel into a specific shape. This is done by placing a steel billet on a block as a hammer drops down making impact with the steel. With repeated blows, these impacts forge the steel into the shape of the mold.
While the drop forge process can utilize different types of forging hammers, the overall process remains relatively the same. Compared to press forging, drop forging has the advantages of being a faster process with lower inital setup costs. It also retains the strength benefits of forging compared to casting.
