Sizing is the squeezing of a specific area of a ductile casting, a forging, or a powder metallurgy to bring it to the desired thickness.

This allows the use of lower cost processes and yet achieve the tolerances that may be needed on a part.

This is useful for areas such as bosses, flanges and similar parts that need to be of a certain specified thickness.
