What is progressive die stamping

Progressive die stamping is a metal stamping process used to produce large quantities of parts with complex geometries. It involves feeding a metal strip through a series of dies, each of which performs a specific operation on the material. As the strip advances, the parts are progressively stamped out until the final product is complete.

This process is often used for high-volume manufacturing of parts with intricate shapes and features, such as electronic components, automotive parts, and household appliances.


Advantages of Deep drawing Stamping

  •  Faster production: Progressive die stamping allows for the creation of complex parts at a faster rate than other stamping methods. This results in quicker turnaround times and increased productivity.
  • Consistent quality: With each stroke of the press, progressive die stamping produces identical parts. This results in a consistent level of quality across all parts produced.
  • Cost-effective: Progressive die stamping can produce large volumes of parts with minimal material waste, which reduces material costs. The speed of production also means that labor costs are lower compared to other stamping techniques.
  • Versatile: It can be used to create parts from a wide range of materials, including stainless steel, brass, copper, aluminum, and more. It is also capable of producing parts with intricate shapes and features.
  • Precision: It uses highly accurate dies and presses to produce parts with tight tolerances and precise dimensions. This ensures that the finished parts meet exact specifications.

Challenges of Deep drawing Stamping

  •  Higher initial tooling setup cost: Compared to stage tooling, progressive die stamping requires more complex tooling which can lead to higher tooling costs.
  •  Not be suitable for every part. Parts with complex geometries, irregular shapes or varying thicknesses may not be able to be produced with progressive die stamping. In these cases, other stamping methods may need to be used which can increase costs.
  • Requires a higher level of expertise to design and manufacture the dies. This can lead to longer lead times and higher development costs.
  • Time-consuming and cost :If changes need to be made to the design or specifications of the part, it may require modifications to the tooling which can be time-consuming and costly.
  •  The potential for scrap and material waste is higher in progressive die stamping compared to other stamping methods, particularly for shorter production runs. This can add to the overall cost of the project.

Additional Process Employed in Progressive Die Stamping

Progress die stamping involves a variety of processes beyond the basic technique of drawing sheet metal into a 3D shape. These processes can be used to further customize and refine the final part.

  • Adding beads, ribs, and flanges to the part’s surface. These raised features can enhance the strength, stability, and rigidity of the part.
  • Bulging:stretches and expands metal in specific areas to create a desired shape or feature.
  • Coining:compresses the metal in a particular area to create a raised or recessed feature, often for decorative or functional purposes.
  • Curling:bending the edges of the metal sheet to form a rounded or curved shape.
  • Dimpling creates a small indentation or depression in the metal sheet, usually for aesthetic or functional purposes.
  • Embossing:raises or recesses a design or pattern in the metal sheet.
  • Extruding is another process that forces the metal through a shaped die to create a continuous profile or shape.
  • Hole forming is used to punch or drill holes into the metal sheet for attachment or assembly purposes.
  • Ironing is a process that compresses the metal sheet to create a smoother and more uniform surface finish.
  • Marking can stamp or laser etch identifying information onto the part, such as part numbers or logos.
  • Necking :narrows the diameter of the metal sheet in a specific area to create a desired shape or feature.
  • Notching :involves cutting small grooves or notches into the metal sheet, often for assembly or attachment purposes.
  • Threading creates threads on the part either by cutting them directly into the metal or by adding a threaded insert.
  • Trimming involves cutting excess material from the edges of the part to achieve the desired final shape and dimensions.

How does progressive die Stamping Work?

Progressive die stamping is a highly efficient and precise manufacturing process used to produce complex metal parts in large quantities. The process involves feeding a metal coil into a series of die stations, each performing a specific cutting, punching, or forming operation on the metal strip or sheet as it moves through the die.

As the metal strip advances through the die, each station applies more pressure, resulting in a more accurate and complex part. The process involves a combination of punching, cutting, and forming techniques to achieve the desired shape and specifications of the part.

Progressive Die Stamping Tooling Design

The reasonable design of the progressive die directly determines the price, quality and capacity of the product.

According to the material, geometry and batch size of the parts used, analyze if the progressive die could be made.

Based on the part drawing, it is necessary to analyze how many processes are required to complete it, study the nature of each process, and arrange them in a reasonable sequence to ensure efficient production.

The strip layout is the basis for designing a progressive die.

The strength of the die, processing possibilities and other factors should be fully considered, and the hole stations should not be too close to each other.

In the progressive die, the distance that each feed advances is called the step distance. Whether the step distance calculation is correct or not is directly related to the quality and dimensional accuracy of the product.

To guarantee that the part is produced correctly and to reduce the danger of flaws, the press speed should be carefully managed.

In general, the edge of the concave die hole edge should not be less than 30 ~ 40mm from the edge of the concave die shape.
The shape and size and tolerance of the convex die are generally determined by calculation methods.

Progress Die Stamping FAQ

Below you will find the answers to the most common questions we get about the metal stamping process. 

Progressive die stamping is a metalworking process that involves feeding a strip of metal through a series of progressive stamping dies in order to create a finished part. The dies are designed to perform multiple operations on the metal strip as it passes through each stage, such as cutting, bending, punching, and shaping. This process is highly automated and efficient, making it a popular choice for mass production of complex parts.

  1. Increased efficiency: Progressive die stamping allows for continuous production of parts, which can improve production rates and reduce lead times.

  2. Reduced waste: This process is highly automated and efficient, which can minimize material waste and lower production costs.

  3. Tight tolerances: Progressive die stamping can produce parts with very tight tolerances, ensuring that each part is consistent and of high quality.

  4. Versatility: Progressive die stamping can be used to produce a wide range of parts in various shapes and sizes, from simple to complex geometries.

  5. Cost-effective: While the initial tooling costs can be high, the per-piece cost of parts produced through progressive die stamping is often lower than other manufacturing processes, making it a cost-effective option for high-volume production.

  6. Consistency: Because the process is automated and highly controlled, progressive die stamping can produce parts with consistent quality and dimensions, minimizing the risk of defects and rejections.

Progressive die stamping and single die stamping are two types of metal stamping processes. Progressive die stamping uses a series of dies, each performing a different operation, to create a finished part. In contrast, single die stamping only uses one die to perform all necessary operations.

One of the main differences between the two is speed. Progressive die stamping is generally faster than single die stamping because it uses multiple dies simultaneously. This can result in higher production rates and lower costs per part.

Another difference is complexity. Progressive die stamping can create more complex parts with greater accuracy and precision. Single die stamping is better suited for simpler parts that require fewer operations.

Overall, both processes have their own advantages and limitations, and the choice between the two depends on the specific requirements of the part being produced.

Progressive die stamping and transfer press stamping are both methods of metal stamping used in manufacturing. While they share some similarities, there are also some significant differences between the two.

Progressive die stamping is a method of stamping in which a sheet of metal is fed through a series of stations, each of which performs a different operation on the metal. As the metal sheet passes through each station, a new operation is performed, and the finished part is produced at the end of the process. Progressive die stamping is often used for high-volume production runs of parts that require multiple operations.

Transfer press stamping, on the other hand, is a method of stamping in which the metal is cut and shaped in a single operation. A transfer press stamping machine moves the metal from station to station, with each station performing a different operation. Unlike progressive die stamping, the finished part is produced in a single operation.

Progressive die stamping is ideal for manufacturing high-volume, intricate metal parts that require tight tolerances and consistent quality. This process is commonly used to produce parts for the automotive, aerospace, and electronics industries, such as connectors, brackets, and terminals. Additionally, progressive die stamping can be used to manufacture consumer products, such as appliance components, hardware, and lighting fixtures. The versatility and efficiency of this process make it a popular choice for a wide range of industries and applications.
