Understanding the Metal Stamping Process | National ...

Although it sounds complex, metal stamping is a relatively simple manufacturing process. It involves using a stamping press to deform and shape a metal workpiece. These heavy-duty machines essentially sandwich a metal workpiece between a set of dies, typically with one die on top and another on the bottom.

During the stamping process, the press pushes the top die down onto the bottom die. Because the metal workpiece is situated between these two dies, it adopts their respective shapes. The bottom of the metal workpiece conforms to the bottom die, while the top takes on the shape of the top die.

Metal Stamping Process

Metal stamping is an incredibly versatile and efficient manufacturing process that takes flat metal sheets or coils and transforms them into precisely shaped and intricate parts. By utilizing force, pressure, and specialized tooling, components with diverse forms — including bends, curves, cutouts, and embossing, are possible. This process offers low costs and higher lead times — both for short and long production runs while keeping consistent quality, dimensional accuracy, and repeatability of the manufactured parts.

How It Works

At the core of metal stamping lies the stamp press, a component responsible for applying the necessary force and pressure to mold the metal sheets or coils into the desired shape or profiles. This powerful machine incorporates specialized tooling known as dies, which performs a variety of stamping operations on the metal. By carefully controlling the movement of the press and the interaction between the dies and the metal in the production line, the stamping process brings forth remarkable transformations in the shape and structure of the material.

Now, let’s dive deeper into the fascinating world of metal stamping and explore its different stages and intricacies.
