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

How Does the Sheet Metal Stamping Process Work?
Sheet metal is one of the strongest materials that can still be easily shaped and cut. Plus, sheet metal is recyclable, which drives costs down.
Metal stamping is used to produce parts in many industries. Original Equipment Manufacturers (OEM) most often make use of sheet metal stamping to make their parts where casting would be too expensive. It’s inexpensive and efficient, but it’s likely you don’t really know how it works.

First, the basics.
Some OEMs produce their own stamped sheet metal on site, while others outsource to Tier 1 suppliers. It is these suppliers that build the dies for stamping down the line.
Sheet metal itself is usually made of steel, but stamping can be done with all kinds of metals, including golds and advanced super-alloys.
Basically, sheet metal stamping involves a flat metal sheet, also known as a blank, being pressed between adie and a punch to get the desired shape.
Blank – the portion of the sheet metal which is punched through the die
Die – defines the outside shape of the part
Punch – defines the inside shape of the part
Ram – moving component which presses down on the metal with upper die pattern
Bolster Plate – stationary lower part of the die
Blank Holder – holds the blank for control during stamping
These parts form the press, the ultimate tool of stamping sheet metal.
Of these, the die is probably the most complicated, and are often designed with inserts to produce variations on standard presses. You’ve probably seen dies used to make novelty souvenir coins — dies can be used for all kinds of processes and materials. They can be small enough to build microelectronics or large enough to cut out sides of busses.
Presses can be built as single stage or progressive blanking tools.
Single Stage Press – stamping operations are done before or after the blanking
Progressive Blanking Press Tools – stamping is done by the machine prior to blanking, so the complete component is punched out throughout the blanking die.
As blanks are punched out of the sheet metal, the come through the die, which is built with a slight angle so that blanks don’t get stuck inside the die. Accidental hold ups can damage the machine, so it’s important that the stamping and blanking process continues smoothly.
Sheet metal presses are powerful machines. It takes about 71 tonnes of pressure to cut a 10 inch circle out of .125 inch sheet metal. Modern presses range from 10 to 50,000 tonnes of force.

After stamping, some parts require further work in a process known as deep drawing. In deep drawing, a flat blank is drawn slowly over a forming die to achieve its shape. Next, excess material must be cut from the deep drawn metal. Finally, the metal might need to be bent, flanged.
