A stamping die is a unique precision tool, which is used to cut metal sheet and form it into a particular shape. Dies contain cutting and forming sections that are usually made from special hardenable steel, known as tool steel. These cutting and forming sections can also be made from different hard wear-resistant materials, like carbide.To get more news about progressive die stamping, you can visit tenral.com official website.

Stamping is a cold-forming process, in which heat is neither used on purpose into the die nor the sheet. However, since the cutting and forming process entails friction, which in turn generates heat, stamped parts that leave the dies are often very hot. Dies used in making microelectronics are available in a variety of sizes, some small enough to fit your palm, while others can reach 20 square ft by 10-ft. thickness and can, therefore, be used in making the sides of an automobile body.

Types of Dies

There are different types of stamping dies, and all perform any of the two basic operations of cutting, forming or both. There are robotically-loaded line dies, manually-loaded line dies, fully-automated progressive dies and fully-automated transfer dies.


The operation most commonly done in a stamping die is cutting. To cut off the metal, it is placed between 2 bypass tool steel sections with a small gap in between them, which is also referred to as the cutting clearance.

Cutting clearance can vary, depending on the type of cutting operation done, properties of metal and the preferred edge condition of the part. Usually, the cutting clearance is expressed in terms of metal thickness percentage. The cutting clearance most commonly used is approximately 10% of the metal’s thickness.
