Deep-Draw Metal Stamping

Deep-draw metal stamping is a high-speed, high-value, shape-transformation process that forms sheet metal into round, square, or irregular components. During the process, a forming die draws the metal into its final geometry through a series of controlled forming operations.

Typically, manufacturers perform deep-draw stamping on a transfer press. This type of machinery dominates the fleet at JMS Incorporated. First, the process begins with a flat blank trimmed from a steel strip. Next, a mechanical transfer system moves the blank from station to station, where each die stamps the material closer to the desired form. As the part advances through the press, each station adds another forming step until the component reaches its finished shape.

Because the part separates from the strip during forming, transfer press technology allows engineers to add more complex features and additional content than traditional strip-fed processes. Traditional strip-fed processes are found in a progressive-die.

The image illustrates this progression: starting with the flat blank on the left and continuing through 13 forming stations until the completed part emerges on the right.
