Progressive Die Stamping Process


In the cutting stage of the progressive die stamping process, we use a stamping die to cut raw sheets of metal into the desired shapes and sizes. Cutting is essential for separating the formed parts from the metal strip, ensuring precise dimensions and clean edges.


Bending is a critical operation in progressive die stamping. During this stage, we shape the metal parts by applying force along a linear axis, causing the material to deform without cracking or breaking. Bending operations create features such as flanges, hinges, and brackets, increasing the part’s functionality.


Coining is a metal forming technique that involves the application of high pressure to produce detailed features on our metal parts. In progressive die stamping, we use coining to create crisp, precise edges and intricate designs that other methods cannot achieve. This process is beneficial for creating product logos, labels, and fine details.


Punching is another essential operation within the progressive die stamping process. During this stage, we use a stamping press to create holes in the metal parts by using a punch and die combination. The punch is pressed into the metal, removing a specified amount of material and leaving precise, smooth-edged holes behind.


Drawing is a crucial step in progressive die stamping, enabling us to form deep, complex shapes in the metal. We achieve this by pulling the metal into a die through pressure from a punch. By controlling the pressure and material flow, we can create formed parts with specified depths and curves.


Embossing involves creating raised or recessed designs on a metal surface. In the progressive die stamping process, we use an embossing die to create texture, patterns, and other visually appealing product features. This process adds value and enhances the aesthetic appeal of the stamped parts.

We use various techniques to create complex, unique parts from raw metal sheets throughout the progressive die-stamping process.

Comparison to Other Manufacturing Methods

This section will discuss how progressive die stamping compares to other manufacturing methods; specifically, transfer dies stamping and traditional metal stamping.

Transfer Die Stamping

Transfer die stamping is a technique that moves sheet metal through various stations to create individual parts. Unlike progressive die stamping, transfer die stamping separates each operation into a single station. This method allows for more versatility in the formation process, which is useful when a part requires traits such as knurls, ribs, threading, or cutouts. Transfer die stamping can help incorporate these features into the procedure, reducing additional costs.

While transfer dies stamping offers more flexibility, it can be less cost-effective than progressive die stamping, mainly when producing smaller parts with tighter tolerances. Progressive die stamping has several advantages, such as:

  • Quick production with minimal scrap
  • Low setup time
  • Reduced labor costs
  • Long run lengths
  • Combining multiple operations, saving time and money

Traditional Metal Stamping

Traditional metal stamping involves using a single-stage tool to stamp a part. This method can be done using line dies or transfer dies (not to be confused with transfer die stamping). Line dies perform one operation at a time for each strike, while transfer dies perform multiple functions at different stages of a single cycle. Traditional metal stamping can be slower and less efficient for creating complex parts with intricate geometries than progressive die stamping.

However, traditional metal stamping may be more suitable for low-volume production or when a part requires less intricate geometries. Some advantages of conventional metal stamping include the following:

  • Simple tooling setup
  • Lower initial costs for low-volume production
  • Capable of producing more significant parts

In conclusion, while progressive die stamping has its advantages in producing complex parts with high efficiency and tight tolerances, transfer die stamping and traditional metal stamping may be better suited to specific applications depending on factors such as part complexity and production volumes.

Design Considerations and Tooling

In progressive die stamping, tooling design is critical in creating quality parts. We must consider several factors before designing a die set to ensure efficiency and precision during the manufacturing process.

First, we need to think about the type of material being used, as this will affect the tooling choices, such as die material, stamping force, and clearances. The material’s thickness and strength should also be considered, as they directly impact the die, cut-off, and bending tolerances.

Next, it’s essential to determine the appropriate die set type depending on the part requirements. Progressive dies are often employed for larger production volumes, while stage tooling or prototype dies may be more suitable for lower volume and more complex geometries.

We must lay out the strip properly to optimize material utilization and minimize waste in designing progressive dies. This involves careful thought about the part orientation and sequencing of the operations, such as bending, forming, cutting, and drawing.

Tooling design also includes accommodating the press and automation requirements. Factors to consider are the press’s tonnage capacity, shut height, stroke length, and feed direction. The die set must synchronize with the automation equipment to ensure smooth production.

Moreover, when designing the tooling, we must account for adequate clearances and tolerances to ensure the proper functioning of the die. This involves considering factors like the cutting edges, hole clearances, and bend radii matching the material’s properties and thickness.

To summarize, tooling design in progressive die stamping demands a keen understanding of multiple factors. By considering aspects like material, die set type, strip layout, and press requirements, and we can ensure that the stamping process produces quality parts with minimal waste and high efficiency.

Project Planning and Best Practices

When planning a progressive die-stamping project, several factors and best practices must be considered. First and foremost, the repeatability of the metal stamping project is essential. To ensure high-quality parts with intricate geometries and fast production speeds, we must develop a robust stamping process that includes an automatic feeding system and progressive stamping dies.

Project Planning and Best Practices

Choosing the appropriate tool steel for the progressive stamping die is vital. We must consider the workpiece material, the desired part geometry, and the production volume to select the most suitable steel. In our experience, high-quality, durable tool steel significantly reduces die maintenance requirements and extends the life of the die.

We must carefully plan the workstations within the progressive stamping die to optimize production lead times. Each station must be designed to perform a specific operation efficiently, maintaining the necessary clearances and cutting angles to avoid damage to the workpiece and the die. The process, from material feeding to part ejection, must be thoroughly analyzed and planned to maximize throughput and minimize downtime.

Some best practices we follow to ensure an efficient progressive die-stamping process include:

  • Regular maintenance of all components, such as cutting sections, form punches, dies, lifters, and springs. This prevents wear and keeps the system performing at its best.
  • Pilot replacement when we detect wear on the pilots to maintain accurate part alignment and prevent damage to the dies and the workpiece.
  • Timely inspection and adjustment of the timing on all inserts to maintain synchronicity and smooth operation of the multi-station progressive die.

Following these best practices, we can achieve faster production speeds and shorter lead times. This, in turn, allows us to provide our customers with high-quality, accurately manufactured components at a competitive price.

Waste Reduction and Recycling

In our progressive die-stamping process, we prioritize waste reduction and recycling as integral components to achieve more sustainable and cost-effective production. We aim to minimize scrap metal and scrap material generation while maximizing the efficient use of resources.

Initially, we strive to optimize material utilization by carefully designing the progressive die layout, which, in turn, allows us to reduce the amount of raw sheet metal needed. This mainly benefits manufacturing high-volume projects, as waste reduction leads to cost savings and a smaller environmental footprint.

When dealing with scrap metal generated during the process, we collect and sort the material to ensure it is ready for recycling. By recycling these materials, rather than discarding them as waste, we contribute to a circular economy and help minimize the demand for virgin raw materials.

Another aspect to consider in the waste reduction process is the removal of burrs and sharp edges from the stamped parts. Deburring is essential to our production process to ensure the final product’s highest quality and safety. We use various methods, such as vibratory finishing, barrel tumbling, and brush deburring, to remove burrs from stamped parts. These processes also lead to the generation of small scrap pieces collected and recycled responsibly.

Furthermore, we continuously review and improve our production methods to find innovative ways to reduce waste and increase efficiency. These improvements range from upgrading our machinery implementing new technologies, and refining our operating procedures.

In summary, as an environmentally conscious manufacturer, we take the responsibility of waste reduction and recycling seriously and continuously strive to make our progressive die-stamping process more sustainable and efficient.
