The low-cost, high-speed, high precision manufacturing processes associated with metal stamping involve the application of diverse techniques, such as:
The blanking process involves the removal of a workpiece from primary material to create the desired form. Unlike punching, the removed workpiece becomes the desired shape or blank.
This technique refers to the use of a die and a punch to cut sheet metal into the required form. During punching, the punch enters the material attached to the die and dispels pieces of metal to create the desired form in the remaining workpiece.
This technique involves the placement of the material between a die and a press or punch. The material is squeezed with extreme force during the press stroke to generate fine features and tolerances on the surfaces of parts.
Bending refers to processes that form sheet metal into desired bent shapes, which are generally the L, U, or V-shapes. The bending process is applied above the material&#;s yield point and around a single axis to form the desired shape.
The flanging process involves the use of a die and a flange or flares produced by a flanging tooling section on a workpiece. The flange portion of the tooling and die form the desired shape in the workpiece.
The drawing and forming stamping process involves the use of compressive force to form sheet metal into a cavity or produce a shaped form by wrapping the workpiece over the desired shape in the die.
The embossing process involves the use of a die and a pressing or stamping machine to apply the shaped die onto the material. The embossed pattern or designed form is then imprinted on the workpiece.
The curling process is used to eliminate sharp edges or form sharp edges into hollow rings according to a specific design. Once performed, curling also increases the moment of inertia at the curled end of the workpiece.
The piercing process involves punching or cutting out holes of closed shapes in a workpiece. The punched-out portion is discarded and the pierced pattern forms the end-use part.
These diverse metal stamping techniques are done individually and can be combined or done in multiple operations to form the intricate parts a project requires. The peculiarities of individual projects are the major determining factors when choosing which metal stamping techniques to apply.
For example, a simple bent design can be developed using bending while intricate tooling sections may combine flanging and piercing or any one of the other techniques outlined above.

The different types of metal stamping utilize the diverse techniques that are applied to produce a finished part with high quality standards. There are three major types of metal stamping, and they are &#; Progressive die stamping, Deep draw stamping, and Fourslide stamping.
With progressive stamping (also referred to as prog die stamping), we move strip metal through a progressive stamping press, where it passes from one station to the next. Each station performs a specific function, including forming, punching, bending, and cutting the metal.
In most cases, progressive stamping requires the use of multiple stations or stages, especially when a project involves complex parts. Progressive stamping offers the advantages of a quick turnaround and the creation of repeated, uniform pieces. It also has the lowest labor cost for each stamping type.
Deep drawing is a technique that uses a punch to feed a blank into a die. It works best for projects in which a customer needs extreme depths on the part shape. Generally, parts with sweeping and deep shapes are used in the Automotive and Aerospace Industries. Deep drawing uses less raw material than other stamping processes. It also works well for producing less-complicated pieces at high volume.
Fourslide stamping is a metalworking process that simplifies the creation of complex parts. It uses four tools that each bend the metal into the required shape simultaneously. While fourslide stamping doesn&#;t create pieces with as much uniformity as progressive stamping, it makes changing or adjusting the design easier when a project requires many parts with different bends.
Metal stamping is a popular manufacturing process for developing parts with tight tolerances using sheet metal, like steel, copper, stainless steel, and aluminum. You can take advantage of metal stamping to manufacture products across diverse industries such as:
Pictured above: A chair leg cup manufactured by The Federal Group.
A few factors play important roles in determining the correct metal stamping process and techniques to use. These factors include the manufacturing budget, shape and size of the manufactured part, production speed, quality, and production volume. Table 1 below can help you in making the right choice:

Metal stamping is an essential process in the manufacturing industry as it enables the production of high-quality, precision parts with minimal waste. The process is used to create a wide range of products, including automotive parts, electronic components, medical devices, and household appliances. The ability to produce complex parts with high accuracy and the consistency makes metal stamping a crucial part of modern manufacturing.
The history of metal stamping can be traced back to the early s when the first machine press was invented. This machine used a flywheel to apply force to a punch, which cut and shaped metal sheets into specific shapes. Over time, the process evolved to include more advanced machinery, such as the hydraulic and mechanical press.
Today, metal stamping has become an integral part of the manufacturing industry, with advanced machinery and techniques allowing for the production of complex parts with high precision and efficiency. The process continues to evolve, with new materials, tools, and technologies constantly being developed to improve the quality and speed of production.

The metal stamping process involves specialized machinery, including dies and punches, to cut and shape metal sheets into specific shapes and sizes. The process is typically performed on flat sheets of metal fed into a stamping press, where they are cut, bent, or shaped using a series of dies and punches.
Metal stamping is a versatile process that can be performed using various techniques depending on the complexity of the part being produced. Here are some of the most common metal stamping techniques:
This technique is commonly used for the high-volume production of parts that require multiple operations to be performed on them. It involves feeding a metal strip through a series of dies that progressively cut, bend, and shape the metal into a finished part. Each die performs a specific operation, which can be automated for high efficiency.
This technique uses a four-slide machine to bend and shape metal into complex parts. The machine has four moving slides that work together to create intricate shapes. Four-slide stamping is ideal for producing parts with multiple bends and shapes.
This technique is similar to four-slide stamping but uses a machine with more than four slides. The process is used to create complex parts with multiple bends and shapes. Multi-slide tooling is ideal for the high-volume production of small parts.
This technique uses a punch and dies to draw a flat metal sheet into a three-dimensional shape. The process creates parts with deep recesses or shapes that cannot be achieved through other stamping techniques. Deep drawing stamping is ideal for producing parts with a high depth-to-diameter ratio.
This technique involves using a series of dies to transfer the metal sheet from one station to another, each station performing a specific operation. The process is used to create complex parts with tight tolerances. Transfer die stamping is ideal for producing large, complex parts.

Metal stamping can be performed on various materials, including metals, alloys, and composites. The choice of material will depend on the specific requirements of the finished part, including the desired properties, strength, and durability.
Tempered and pre-tempered metals are two different types of metal alloys used in metal stamping. Tempered metals are heated to a high temperature and then cooled rapidly to create a hardened surface. This process is called quenching, making the metal much stronger and more resistant to wear and tear.
On the other hand, pre-tempered metals have been tempered before they are used in stamping. This means the metal has already undergone quenching and has a hardened surface. As a result, pre-tempered metals are more uniform in their hardness and have more consistent mechanical properties, making them easier to work with during the stamping process.
The choice between tempered and pre-tempered metals depends on the specific requirements of the part or component being produced. For example, pre-tempered metals are often preferred for applications where high precision and uniformity are required. On the other hand, tempered metals are often used in applications where the metal needs to be harder and more wear-resistant.
Metal stamping is a versatile and efficient manufacturing process that involves shaping and forming metals into various parts and components. Several types of metal stamping techniques include progressive die stamping, four-slide stamping, multi-slide tooling, deep drawing stamping, and transfer die stamping. Each technique offers its advantages and is suitable for specific applications. The choice of material is also important in metal stamping, with a wide range of metals and alloys available, including pre-tempered metals such as martensite, stainless steel, and brass. Metal stamping is a cost-effective and reliable process widely used in various industries to produce high-quality parts and components.
