Stamping (also known as pressing) is the process of placing flat sheet metal in either blank or coil form into a stamping press where a tool and die surface forms the metal into a net shape. Stamping includes a variety of sheet-metal forming manufacturing processes, such as punching using a machine press or stamping press , blanking, embossing ...
Blanking is a punching operation in which the entire periphery is cut out and the cutout portion required is known as STAMP or BLANK. When a component is produced with one single punch and die where the entire outer profile is cut in a single stroke the tool is called a blanking tool. Blanking is the operation of cutting flat shapes from sheet ...

Coining can be done using a gear driven press, a mechanical press, or more commonly, a hydraulically actuated press. Coining typically requires higher tonnage presses than stamping, because the workpiece is elastically deformed and not actually cut, as in some other forms of stamping. The coining process is preferred when there is a high tonnage.
Precision Metalforming Association or PMA is a trade association [1] representing the $137-billion metalforming industry of North America: the industry that creates precision metal products using stamping, fabricating, spinning, slide forming and roll forming technologies, and other value-added processes. PMA’s origin was the Pressed Metal ...
A file is an abrasive surface like this one that allows machinists to remove small, imprecise amounts of metal. Filing is combination of grinding and saw tooth cutting using a file . Prior to the development of modern machining equipment it provided a relatively accurate means for the production of small parts, especially those with flat surfaces.

Hot stamping (also known as press hardening, hot press forming, or hot forming die quenching) is a relatively new technology which allows ultra-high strength steels (typically 22MnB5 boron steel [1]) to be formed into complex shapes, which is not possible with regular cold stamping operations. [2] This process is commonly used for the ...
