Precision Metal Stamping: 4 Common Questions

By Graham Arid


Metal stamping takes on a crucial role in modern-day manufacturing in sectors that most individuals don't even realize. From household appliances to auto parts, bridges and even surgical instruments. Precision metal stamping helps produce essential parts of an array of devices comprised of sheet metal that must be punched, pierced, imprinted or formed into a variety of shapes.

How does metal stamping work?

Metal stampings machinery is made up of heavy machines equipped with stamping die, or specialized tools by which sheet metal is pressed until the the piece is produced in its desired form. It is possible that it can take many passes in the stamping die before the piece of sheet metal is a finished product. Sheet metal is probably the most common material used due to its light weight and strength. A number of processes use alternative metals, such as stainless-steel stampings, brass or copper stamping.

What are some examples of the different types of metal stamping?

Progressive metal stamping is the method used most often in manufacturing. This process merges several different individual facets of the stamping process in a single machine to simplify the operation. On a regular basis, parts of the stamping process like punching, coining and folding are coordinated to ensure that the metal moves rapidly within the press. A different type of stamping, the multi-slide process, makes use of a number of dies working together with each other in a press to create a metal stamping that has multiple sides.

What is deep drawn metal stamping?

Deep drawn metal stamping represents a procedure wherein the part that is being formed by the die is of a greater depth than the width of the metal being used to form it. These pieces are generally parts of machinery that are very recessed. Deep drawn stamped pieces are manufactured using flat sheets of various materials such as aluminum, copper, bronze or stainless steel stampings. Deep drawn parts are often cheaper and more efficient to manufacture than parts created by machining or casting molds.

So what are a few benefits of metal stamping?

The multi-faceted processes of metal stampings allow many metal sheets to be stamped at one time, providing a savings cost for a manufacturing company. The main benefit is the lower expense regarding large scale production of stamped parts. The capacity to manufacture parts through the stamping process which are stronger, yet more lightweight and flexible is one other significant advantage for companies using the process. More often than not, steps in the manufacturing process can be combined in the precision metal stamping process to save time as well as money.
