Process Description ~ Forging (metals)

• A set of dies are prepared that rough out, then

gradually approach, the shape of the finished

product.

• The metal to be forged is heated until it will form

easily

• The heated metal is impacted in the die, producing a

change in shape and (usually), flashing

• The die is opened and the part is removed.

• The part is trimmed for the next forging die.
