| Sheet metal stamping is the system wherein | | | | metal stamping companies after the metal sheet |
| metal sheets are used for producing final | | | | is stamped.There are three main components in |
| products. When a metal sheet is inserted into the | | | | sheet metal stamping -- the die, the punch and |
| die or the press, it is molded into the required | | | | the binder/blank holder. The sheet is kept |
| shape and size. Metal sheets of only a certain | | | | between the blank holder and the die and the |
| thickness can be inserted into metal stamping | | | | punch is driven into the die wherein the sheet |
| machines. The maximum limit for most metal | | | | spreads over the die because of the drawing and |
| stamping machines is ¼ inch. However, | | | | stretching. The blank holder provides the |
| machines can be designed to accommodate | | | | restraining force that is required to control the |
| sheets of greater thickness also. Even the kind of | | | | sheet flow into the die. This force prevents |
| metal sheets that can be processed in metal | | | | wrinkling and tearing of the sheet as the quantity |
| stamping are also specific. Only certain metals or | | | | of material going into the machine can be |
| alloys can be used like aluminum, brass, steel (hot | | | | controlled. For some processes where the blank |
| rolled or cold rolled), galvanized steel, stainless | | | | holder force is too high for the material, draw |
| steel, copper, zinc and titanium.Before the metal | | | | beads are used to create the restraining |
| sheet is inserted into the machine, the customer | | | | force.Sheet metal stampings are also known as |
