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 ...
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.
Sheet metal embossing is a metalworking process for producing raised or sunken designs or relief in sheet metal.In contrast to coining (which uses unmatched dies), embossing uses matched male and female dies [1] to achieve the pattern, either by stamping, or by passing a sheet or strip of metal between patterned rollers.

Metal fabrication is the creation of metal structures by cutting, bending and assembling processes. It is a value-added [ 1 ] process involving the creation of machines, parts, and structures from various raw materials.
Progressive Die is a metalworking method that can encompass punching, coining, bending and several other ways of modifying metal raw material, combined with an automatic feeding system. The feeding system pushes a strip of metal (as it unrolls from a coil) through all of the stations of a progressive stamping die. [1]
The more common form of jewellery was the hammered sheet type. Sheets of metal would be hammered to thickness and then soldered together. The inside of the two sheets would be filled with wax or another liquid to preserve the metal work. Different techniques, such as using a stamp or engraving, were then used to create motifs on the jewellery.
Jewelry wire is wire, usually copper, brass, nickel, aluminium, silver, or gold, used in jewelry making. Wire is defined today as a single, usually cylindrical, elongated strand of drawn metal. However, when wire was first invented over 2,000 years BC, it was made from gold nuggets pounded into flat sheets, which were then cut into strips. The ...
