Precision metal stamping, sometimes referred to as progressive metal stamping, is a popular manufacturing process that enables a range of industries to produce incredibly precise parts in an efficient and affordable manner. Manufacturers will opt to use this process for many applications, and having a firm understanding of its advantages and capabilities ensures that you will reap all the benefits when choosing precision metal stamping.
What is Precision Metal Stamping?
This process utilizes machinery fitted with dies in order to transform sheet metal into custom shapes at incredibly tight tolerances. The manufacturer may even be able to complete the piece with a single stroke of the press, which is known as a single-stage operation. More complex pieces may require multiple strokes, which is referred to as a series operation. Precision metal stamping is flexible and adaptable, and is particularly beneficial for high-volume manufacturing.
Its immense level of precision, even for complex parts, is what sets this process apart from similar machining options. Precision metal stamping machinery enables manufacturers to perform microstamping, crafting complex minuscule parts where even the smallest error could render the final product ineffective. The accuracy and efficiency of precision metal stamping in crafting these parts has created a high demand in industries ranging from automotive to aerospace.
Projects using precision metal stamping will typically begin with computer modeling, virtually simulating the stamping process to check for errors or defects. Once this testing is complete, the computer will send the design straight to the machinery in an efficient process that reduces the chances of human error.

There are three main tooling methods for precision metal stamping:
- Soft Tooling. A straightforward, single-machine method for smaller production runs.
- Stage Tooling. Adds several machines to the process, with workers manually moving the workpiece between machines.
- Hard Tooling. A fully automated process best for high volume output.
Depending on the project and tooling method, manufacturers may choose from a myriad of techniques to use, including:
- Bending
- Stretching
- Embossing
- Punching
