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 .

Coining is a form of precision stamping in which a workpiece is subjected to a sufficiently high stress to induce plastic flow on the surface of the material. A beneficial feature is that in some metals, the plastic flow reduces surface grain size, and work hardens the surface, while the material deeper in the part retains its toughness and ...
Stamping includes a variety of sheet-metal forming manufacturing processes, such as punching using a machine press or stamping press, blanking, embossing, bending, flanging, and coining. [1] This could be a single stage operation where every stroke of the press produces the desired form on the sheet metal part, or could occur through a series ...
Coining: is similar to forming with the main difference being that a coining die may form completely different features on either face of the blank, these features being transferred from the face of the punch or die respectively. The coining die and punch flow the metal by squeezing the blank within a confined area, instead of bending the blank.
Chasing (French: ciselure) or embossing is a similar technique in which the piece is hammered on the front side, sinking the metal. The two techniques are often used in conjunction. The two techniques are often used in conjunction.
Similarly, the strip lay-out must be determined (strip width and pitch). The bridge width between the parts and the edge allowance between the part and the edge of the strip also have to be selected. A simple operation may only need a pancake die. While many dies perform complex procedures simultaneously, a pancake die may only perform one ...
Although it's often referred to as the "Hobby of Kings," coin collecting doesn't discriminate between the rich and the poor (or between the regal and the common folk). While buying known rare coins...
Guide Pillar & Guide Bush : Used for alignment between top and bottom halves of the press tools. Bottom plate:It is used to hold bottom half of the press tool with press slide. Stripper plate: it is used to strip off the component from punches. Strip guides: It is used to guide the strip into the press tool to perform the operation. Press tool
