The Sheet Metal Stamping Process

Sheet metal stamping is a cold-forming process that uses a die to shape flat metal sheets into specific parts or components. This process is widely used to produce high-precision metal parts in large volumes, with applications ranging from automotive body panels to consumer electronics enclosures.

The process begins with a flat metal sheet, typically made from materials such as steel, aluminum, copper, or brass, which is fed into a stamping press. The die is used to cut, bend, or emboss the sheet metal, creating the desired shape. The precision and efficiency of this method make it an excellent choice for producing high-quality, complex parts at scale.

Types of Sheet Metal Stamping Dies

At Kuasu Moldtec, we offer a variety of sheet metal stamping dies tailored to the specific needs of our customers. These include:

Progressive Dies: These dies are used for high-volume, multi-step operations. As the metal sheet moves through the die, it undergoes multiple stages of stamping, such as cutting, bending, and forming, with each pass producing a more complex part. Progressive dies are ideal for producing large quantities of small to medium-sized parts with high precision.
Single-Action Dies: These dies perform a single operation, such as cutting, punching, or bending. Single-action dies are typically used for smaller production runs or for creating parts that do not require multiple operations.
Compound Dies: Compound dies are capable of performing two or more operations simultaneously on a single stroke, such as cutting and bending. This makes them an excellent choice for parts that require multiple processes in a single press cycle.
Blanking Dies: These dies are used to cut out flat, shaped metal parts from a larger sheet. Blanking is often the first step in the stamping process, producing the base shape that will undergo further operations, such as bending or embossing.
Forming Dies: Forming dies are used to shape sheet metal into a 3D part through processes like deep drawing, stretching, or bending. These dies are commonly used in applications where parts need to maintain specific geometric shapes, such as in the automotive industry.

What is a Stamping Die ?

Stamping dies are the tools that shape and cut sheet metal parts. which are 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. 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. It typically consists of a punch and die set, and may include additional elements like strippers, lifters, and springs for more complex operations. Stamping dies are usually made from hardened steel, which allows them to withstand the stress of high-pressure operations and produce consistent results over time. They are essential in industries such as automotive, aerospace, and electronics, where they are used to create parts like body panels, structural components, and electronic casings. Stamping dies can be categorized into different types based on their functions and the level of automation involved, such as single-stroke dies, progressive dies, and compound dies. Each type serves unique manufacturing needs depending on the complexity and volume of the parts being produced.

They are commonly developed using computer-aided design (CAD) software and analytical programs to create and prove-out highly accurate, unambiguous designs. These designs are then translated into stamping dies by skilled craftsmen, known as diemakers.

What is The Difference Between a Die Casting and a Stamping Die?

Die casting utilizes ingots or billets, while stamping requires sheet metal blanks or coils; metal is heated past its melting point to be die casting, while stamping is almost always a cold working process. The two different processes also have different strengths and weaknesses.

Die casting and stamping are two different metal forming processes, each with its own characteristics and applications. Here are the main differences between them:
