.... The flattener station can be either a flat area on the face of the die or an impression in the die to give the exact size required. Benders A portion of the die can be used to bend the stock, generally along its longitudinal axis, in two or more planes. There are two basic designs of bender impressions...

... roll forging dies with progressive shape changes. The roll dies act like a roll as well as a forging die. Forging rolls are available in numerous sizes and have the capacity to roll blanks up to 200 mm (8 in.) thick and 1920 mm (75 in.) long. The roll dies usually have multiple progressive impressions...

.... In the indentation hardness test, a blunt indenter that approximates a flat punch is forced into a plane surface. The size of the impression that remains after the indenter is removed is a measure of the hardness of the indented body. Hardness is usually expressed in units of pressure (mg/mm 2 or psi), obtained...
