Stamping (metalworking)
Stamping (also known as pressing) is the process of placing flat sheet metal in either blank or coil form into a stamping press where a tool and die surface forms the metal into a net shape. 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. 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 of stages. The process is usually carried out on sheet metal, but can also be used on other materials, such as polystyrene. Stamping is usually done on cold metal sheet.

Stamping Operations
1. Bending - the material is deformed or bent along a straight line.
2. Flanging - the material is bent along a curved line.
3. Embossing - the material is stretched into a shallow depression. Used primarily for adding decorative patterns.
4. Blanking - a piece is cut out of a sheet of the material, usually to make a blank for further processing.
5. Coining - a pattern is compressed or squeezed into the material. Traditionally used to make coins.
6. Drawing - the surface area of a blank is stretched into an alternate shape via controlled material flow.
7. Stretching - the surface area of a blank is increased by tension, with no inward movement of the blank edge. Often used to make smooth auto body parts.
8. Ironing - the material is squeezed and reduced in thickness along a vertical wall. Used for beverage cans and ammunition cartridge cases.
9. Reducing/Necking - used to gradually reduce the diameter of the open end of a vessel or tube.
10. Curling - deforming material into a tubular profile. Door hinges are a common example.
11. Hemming - folding an edge over onto itself to add thickness. The edges of automobile doors are usually hemmed.
Piercing and cutting can also be performed in stamping presses. Progressive stamping is a combination of the above methods done with a set of dies in a row through which a strip of the material passes one step at a time.

Industry-specific applications
Metal stamping can be applied to a variety of materials based on their unique metalworking qualities for a number of applications across a wide range of industries. Metal Stamping may require the forming and processing of base common metals to rare alloys for their application specific advantages. Some industries require the electrical or thermal conductivity of beryllium copper in areas such as aerospace, electrical, and the defense industry or the high strength application of steel and its many alloys for the automotive industry. Industries metal stamping is used for:

• Aerospace
• Agriculture
• Ammunitions
• Major appliances
• Small appliances
• Automotive
• Commercial
• Construction
• Electronics
• HVAC
• Lawn Care & Equipment
• Lighting
• Lock Hardware
• Marine

Metal Stamping Techniques

Sheet metal stamping, the processes

In sheet metal stamping processes are included a wide variety of associated operations:

Metal blanking: sheet blanking on iron, aluminum, copper, brass and special alloys is carried out with punching and matrixes.

Sheet metal deep-drawing: which can turn flat metal sheet transforming it into metal components such as cylinders, hemispherical caps, or finished products such as pots and pans or other kinds of containers.

Sheet metal bending: used to obtain semi-finished products through the pressure exerted by the mold during the metal working.

Sheet metal punching: achieved by using automatic CNC machines and standard or special punches and tools, is performed on iron, stainless steel, aluminum, copper, brass and special alloys.

Metal threading: used to fix together two or more metal parts.

Sheet metal laser cutting: performed using numerical control machines, capable of achieving the precision cutting standards foreseen during the design & engineering phase.

As you can see, there’re many processes linked to sheet metal stamping. These are the main processes involved to manufacture metal parts in all industries fields: automotive, household appliances, medical, logistic and plant system sectors and infinite others.

Sheet metal stamping, the functioning

In sheet metal stamping, there’re two types of stamping presses: hydraulic and mechanic. Both use “dies” to manufacture stamped parts.

The entire “die” consists in a male and female part, which work in opposition. The upper part of the die is set on the first half of the press, while the second half is fixed on the lower half of the press.

When the mechanical or hydraulic press is activated, the flat sheet metal, which stands between the die, reaches the desired shape.

The result is always a solution which let to produce large quantities of metal parts with affordable costs and an excellent level of precision.
