Tool & Die Manufacturing
Crafting Consistent and Precise Metal Components
One of the most common and versatile manufacturing techniques, metal stamping is a cold-forming process that presses raw material into a die to change its shape. Stamping allows manufacturers to quickly process high-volume runs, crafting consistent and precise metal components at minimal expense.
Tooling is key to the success of any stamping project. In particular, the stamping die itself must be designed to yield precise results, and it must be well-made to prevent premature wear. In this guide, the experts at Keats Manufacturing have compiled everything you need to know about manufacturing custom stamping dies to help you better assess your tooling needs. The information that follows will put readers in a more informed position when it comes time to assess and select stamping die suppliers.
What is a Stamping Die?
In metal stamping, a male punch forces a piece of sheet metal into a female die with a matching concave shape. The stamping machine applies sufficient pressure until the metal is forced to conform to the die’s shape without the application of heat. Depending on the application, the die may be designed to form or cut the metal or may do both at once.
Stamping dies vary drastically in size and geometry, as they can be used for projects ranging from microelectronics to aerospace components. There are also subtypes of dies used in specific types of stamping. For instance:
- Progressive dies are used in progressive stamping, a process in which the component undergoes multiple sequential cutting and bending operations while still attached to a longer metal strip. Like transfer dies, progressive dies are used exclusively in multi-station stamping.
- Transfer dies are similar to progressive dies in that they are used for sequential operations in high-volume manufacturing, although transfer stamping does not use a connected metal strip like progressive stamping. The primary difference is that transfer dies are usually used with larger or deep-drawn components, which are transferred in between stations.
- Line dies allow for tandem-line stamping of large components and are especially suitable for projects that cannot be manufactured with a single stamping press.
- Compound dies are a broad category that encompasses all dies that perform both a cutting and a shaping operation in a single stroke of the die press. Compound dies are an excellent choice for maximizing efficiency.
The best type of stamping die for your project depends on the manufacturing technique and the geometry of your component. Your supplier can help you determine the most suitable option for your needs.
Cutting Operations for Stamping Dies
Stamping dies each perform one or more forming or cutting operations on a metal blank. Although there is an extensive array of potential stamping operations, the following cutting methods are among the most common:
What is the Difference Between Tooling & Die Manufacturing?
It’s important to note that while stamping dies are a form of tooling, not all tooling manufacturers are experienced in die manufacturing. Toolmakers may produce or modify any number of cutting tools, forming tools, or fixtures. Their repertoire sometimes — but not always — includes stamping dies. Conversely, diemakers specialize in die manufacturing, which has its own set of unique considerations.
Die manufacturing requires the utmost precision, as the shape of the die directly determines the shape of the final components. Since stamping is most often employed for high-volume production runs, any errors in the die could potentially be passed on to hundreds of thousands of components. Dies may also take very intricate shapes, especially when used for combination processes or multi-station manufacturing. Not all tools must adhere to these same standards of precision, so it’s important to work with a manufacturer who can demonstrate extensive experience with stamping dies specifically.
An experienced die manufacturer is far more familiar with the diverse array of die types than a standard toolmaker. While a general tooling manufacturer may have the technical capacity to create a stamping die, they can’t always offer the personalized design guidance that comes from an expert in the field. This factor is especially important given the extensive number of variations available for stamping dies. A die manufacturer is in a much better position to help you identify and source efficient tooling compared to a contractor who is more detached from the industry.
