Forging
Thu, 10 Apr 2008
Take a piece of metal,
strike it with a hard enough blow that it bends, or is shaped, and
you've got the concept of forging. There are two kinds of
forging: Hot and cold. Cold forging is done at room temperature and
gives a good finish and excellent dimensional control. Cold forging is useful for cutlery for example. In hot
forging, the ductility of the metal is increased by heating the material.
The
forging process called closed-mold involves putting a work piece over a
metal mold, which sits atop and anvil. A hammer then forces the work piece into the mold. Such forging (drop hammer
forging) is often done sequentially, moving from a shallow die to
progressively deeper ones. Some material does not enter the die and is called "flash" which is later removed.
Various shapes and sizes can be formed through forging.
