What Is Closed-Die Forging?
Closed-die forging, or impression-die forging, involves metal being placed between one or more custom-shaped dies. The metal is hammered or pressed, causing it to flow and fill the shaped-die cavities.
Closed-die forging is one of the most commonly used methods for forging steel parts. This process works with the metal’s internal grain structure and can produce stronger, longer-lasting products.
Little to no machining is needed for closed-die forgings. The process simply utilizes the force from a closed-die forging hammer or press, and heat, to deform the metal to fill the die impression or mold.
THE ADVANTAGE OF FLASH IN CLOSED-DIE FORGING
Where both die forgings can result in a thin layer of flash (excess material squeezed out during the die forging process) the closed-die process uses the flash to its advantage. As the flash promptly cools, it increases pressure on the impression, which encourages the metal flash to flow into details/crevices. The excess flash is then manually removed.
CLOSED-DIE FORGING PROS
Better surface finish and superior mechanical properties
Reduced or no machining
Cost-effective for large production runs
Dimensions with tighter tolerances and various shapes can be achieved
More precise, consistent impressions
Ability to reproduce nearly any shape and/or size
CLOSED-DIE FORGING CONS
Not typically economical for short or small production runs due to the cost of die production
Higher setup cost due to costly machines and furnaces
