Stamping (metal working) is also known as pressing, which is the process of placing flat iron 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.

Sheet Metal Stamping (die and processes) involved:

The Stamp presses and stamp dies are tools used to produce a high volume of metal parts.“Die” is a generic term used to describe the tooling used to produce stamped parts. A die set consists of a male and female component and is the actual tool that is responsible for producing the shaped stamping and the most common types of dies perform cutting and forming. Cutting dies are used to shear sheet material into what is called a blank and these blanks are exposed to blanking dies, which are stamped into parts.

Another function of the cutting dies is punching, which is the cutting of a slug from the sheet metal stock to produce a hole or slot. Cutting dies are also used to trim excess metal from around the formed part.

Forming, is a term used that best describes a stamp part whose shape is reproduced directly from the shape and contours of a die set. Drawn blanks are subject to wrinkling, thinning and fracturing without sufficient formability.

Main forming operations that are accomplished with the press mounted dies are:

• Drawing - also known as forming, is the process that involves forcing a blank deeply into a die cavity and then shaping it into the form and contour of the punch face and sides.

• Bending – is a simple forming operation that provides rigidity and shape to sheet metal parts

• Flanging is similar to bending and its functions are: providing a more finished appearance, rigidity, edge strengthening or attachment service

• Hemming – involves the folding over of a short flange upon itself to form a smooth rounded edge that facilities the attachment of mating parts

A series of consequential operations are produced with each press stroke. Progressive and transfer types die are used. Coil stock is feed with the progressive die into the press.

Each stampings are connected in the carrier strip and are separated and discharged from the press after they go through the various die operations. The stock is moved from press to press and operations such as drawing or trimming are performed when large stampings are performed.

Sheet metal stock’s resistance to the forces that are performed by the moving dies creates friction and for this reason, lubricant is applied. Lubricant comes in a variety of options that range from light material oils, water soluble or synthetic.

Lubricant maybe applied by any of the following methods:

• Manually or with the use of a roller or brush

• Drip

• Machine roller

• Spraying


A tool called Circle Grid Analysis or CGA is used to help fine tune the stamping process along with finalizing the die design.

Production stamping is usually performed on .020” to .080” thick material but could also be applied to foils as thin as .001” or plate stock with thickness almost to 1.000”.

The Stamping process is usually carried out on a metal sheet but can also be used on other material such as polystyrene.

Purchasing Tips:

Stamping systems are made up of five (5) high performing ingredients that must be considered before finalizing a purchase:

• A sound part design

• Wee-designed and durable progressive stamping die

• The stamping press

• Material handling/ancillary automation that surrounds the stamping process

• Completed manufactured stamped part

Extensive time should be spent searching for:

• Talent

• Expertise

• Track record

• Key skills required

The use of rigorous approach when evaluating a stamping supplier and conversing about the indicators will greatly assist in the decision making process.
