Many traditional power press metal stamping companies can only do one action: short-run stamping with a single stroke. However, the progressive stamped parts method necessitates using a single tool for multiple operation required to produce a final item. Traditional power press metal stamping may result in long lead times, high labor costs, and the inability to produce delicate or tight-tolerance parts.
Fortunately, a stamping technique, known as progressive stamping, which ESI has perfected for more than two decades. Fabricating pieces that required more than a couple of bends was traditionally expensive and inefficient. A maker might replace the tool on a single press several times or occupy several machines, each doing one activity required for a finished part. Secondary machining services were frequently necessary to completely complete a product, even when many presses were used.
Machine shops get improved capabilities with progressive stampings, such as
- Increased manufacturing rates
- The Efficiency of the Process
- Manufacturing at a low cost
What is the definition of die stamping?
Die stamping is a cold-forming method that involves cutting and shaping a sheet of metal using a single or sequence of dies to achieve a desired shape or profile. The force used to the blank modifies and changes its geometry. The causing stress in the workpiece bends or shapes it into complicated shapes. Depending on the purpose, the pieces produced can be exceedingly microscopic or incredibly huge.
Punching, blanking, piercing, coining, and various additional processes are all part of the die stamping process, also known as pressing. Each punch must produce ideal quality; thus, designs must be accurate.
Die metal stamping uses specialized tools that have been tailored to make a specific design, which can be simple or complicated.

Considerations for Parts Produced by Progressive Stamping
While progressive die stamping may appear to be a straightforward operation, a lot goes into determining the best approach to create a part.
Shapes to Think About
The shape may not be able to be manufactured if the tolerances provided are too tight. The form, width, and full size of the part shape determine the recommended tolerances.
Here, too, the material plays a role. Steel, for example, can begin to sheer or break away at an angle as you cut it. The majority of manufacturers aim for a sheerness of 30% or less. You may need to raise the clearance of the die block to minimize shearing to keep the hole at the required size.
Material Points to Consider
The following materials are frequently stamped:
- ● Steel that has been hot rolled
- ● Steel that has been cold rolled
- ● Stainless steel is a durable material.
- ● Bronze
- ● Brass (half-hard)
Your material selection can be based on the end product’s function and the strength and resistances it will require.
Size & Thickness
Because everything from microscopic screws to car hoods can be stamped, the size and tonnage capabilities of the manufacturer’s equipment are the deciding factors. In addition, various materials and thicknesses will necessitate varying applied forces.
Can Your Progressive Die Stamping Services Be Outsourced?
It may be worthwhile to outsource to a seasoned manufacturer with so many factors to consider when producing progressive die-stamped parts. However, single sourcing can reduce shipping costs and lead times, so look for a full-service vendor who can also help you with secondary operations such as:
- ● Electroplating
- ● Heat Treatment
- ● Riveting
- ● Ultrasonic Cleaning
What, though, is even more crucial than machine capabilities? To match it, engineers created a design. So, before you turn on the machines, make sure you have the engineering staff in place to meet your specific functionality requirements, whether it’s in-house or outsource.
Conclusion
With progressive die metal stamping, you may make parts with various shapes using a single tool. All the part’s requisite geometries are attained in a single Progressive Die operation. Long runs are possible thanks to the progressive stamping process’s continuous material supply. Longer runs between material changes and tooling modifications allow for faster production of your parts.
All of the elements mentioned above help to lower the overall cost of your item. In addition, progressive die metal stamping allows you to make strong parts most quickly and cost-effectively possible.
