Sheet metal stamping is the system wherein metal sheets are used for producing final products. When a metal sheet is inserted into the die or the media, it is molded into the required shape and size. Metal sheets of only a particular thickness can be inserted into metal stamping machines. The maximum limit for most metal stamping machines is 1/4 inch. But, machines can be made to accommodate sheets of greater depth too. Even the kind of metal sheets which can be processed in metal stamping are also specific. Only certain metals or metals can be used like aluminum, brass, steel (hot rolled or cold rolled), galvanized steel, stainless steel, aluminum, zinc and titanium.
Ahead of the metal sheet is inserted into the machine, the customer provides the model or at least a diagram of the final product. In the event the customer doesn't have a good idea of what the final product should look like, most metal stamping producers also provide engineering services for designing the goods as well. Even some secondary services such as deburring and plating are provided by the metal stamping companies following the metal sheet is stamped.
There are three main components in sheet metal stamping -- the die, the punch and the binder/blank holder. The sheet is retained between the holder and the die and the punch is driven into the expire wherein the sheet spreads across the expire due to the drawing and stretching. The blank holder provides the restraining force that is required to restrain the sheet flow into the die. This force prevents wrinkling and tearing of the sheet as the number of substance entering the machine can be controlled. For some processes in which the blank holder force is too high for the material, draw beads are used to create the restraining force.
Sheet metal stampings are also known as thin stampings. Sheet metal stamping can be used most primarily from the case-building process. It's also the most important part as all the panels has to be stamped one by one. The motherboard tray is stamped, then one-side panels on the right and left from bottom to top and back.
