Sheet metal stamping is a process that produces items like coils, springs and electrical contacts. It involves a number of processes that transforms a simple sheet of metal into parts that are used in electronic or industrial machinery. Some of the common processes involved in this kind of metal manipulation include punching, coining, embossing, bending and blanking. These processes are done with the help of a stamping machine.
More modern stamping machines can produce more complicated and specialized products by combining several metal stamping processes in one attempt. The application of several processes onto one sheet of metal is called progressive stamping. In this procedure, the raw sheet metal is fed into the system automatically, resulting in consistent forms. This also eliminates the need for extra manpower. This mechanized process increases the speed by which a batch of forms is completed.
In progressive sheet metal stamping, a sheet of metal is mechanically fed into the stamping machine. These sheets can either be pre-cut or obtained from a roll. Once fed into the machine, the sheet undergoes several changes as different stamping dies are applied onto it. These dies are chosen prior to assembly and are based on the customer's specifications. Once the desired form is produced, it will be cut from the carrying web and packaged.
