Stamping(also known as pressing) involves placing flat sheet metal, in either coil or blank form, into a stamping press. In the press, a tool and die surface form the metal into the desired shape. Punching, blanking, bending, coining, embossing, and flanging are all stamping techniques used to shape the metal.

The metal stamping consists of a process of machining without starting of shaving where the steel sheet is cut by means of presses for the achievement of certain metallic pieces. For this in the presses the dies are placed with the necessary operations.

Material:

Aluminum alloys

Brass alloys

Copper alloys

Steel and stainless steel

Advantages: 

Cost efficiency in production: Labor costs drop as production levels increase, making precision metal stamping a good choice for high-volume production of complex parts.

Speed– Progressive die metal stamping is based on the continuous feed of material through the different die stations of a tool.  The nature of the process allows you to create more parts in a shorter period of time when compared with traditional fabrication or machining.  For high volume parts, progressive stamping provides the lowest cycle times per part.

High Repeatability – The hard tooling die designs allow for high volume runs without die degradation.  This means that part quality remains high and there are fewer failed parts.

Lower Cost per Part – All of the factors above contribute to reducing the overall cost of your part.  Using progressive die stamping allows you to create robust parts in the most cost effective and expeditious manner.

Disadvantages:

One of the disadvantages of stamping is the higher cost of presses. 

The dies must also be acquired or created, and producing custom metal stamping dies is a longer pre-production process. Dies can also be difficult to change if the design must be altered during production.
