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.
