A Leader in Die Forging

Anderson Shumaker is a leader in open die forging. We’ve been forging this way since 1902. Open die forging is the best method to meet tolerances. For example, it results in completely filled, finished parts and it creates the least amount of material waste. But what exactly is “open die forging”? Let’s break it down:

Open Die Forging

Open die forging (“free forging”) deforms metal between multiple dies. These dies hammer the metal to alter its dimensions. As a result, the metal achieves its desired shape. Open die forging results in better fatigue resistance, improved microstructure, continuous grain flow, increased strength, and less flashing. Most importantly, it offers overall cost savings.

Closed Die Forging

On the other hand, closed die forging (“impression forging”) compresses metal to fill enclosed dies. For example, as the dies press together, the metal fills the impressions. This causes the excess material to be squeezed out. Likewise, closed die forging results in better surface finish, no material limitation, tighter tolerances, and increases product strength. Consequently, is a great choice for large production runs.

Anderson Shumaker: Leaders in Open Die Forging

Our open die forging process results in metallurgical soundness and improved mechanical properties. Strength, toughness, and general durability depend on the material’s grain placement. Therefore, our techniques produce a high degree of grain refinement. Open die forging’s final step is typically machining. Machining achieves accuracy and a desired finish. To this end, Anderson Shumaker keeps machining and finishing in-house, because we like saving our customers both time and money.
