1. Wire Feeding & Cutting: The process begins with feeding a coil of wire into the machine. The wire is straightened as it enters and is then cut to predetermined lengths, preparing it for the first forming operation.

2. First Stage (Die 1 & Blow 1): In this initial station, the cut piece of wire undergoes its first deformation. This might involve preforming the head or starting the shaping of the shank. The primary goal is to establish the basic form of the fastener.

3. Second Stage (Die 2 & Blow 2): The partially formed blank moves to the second station where additional shaping occurs. This could include further development of the head shape or the beginning of forming other features such as underhead recesses or thread starts.

4. Third Stage (Die 3 & Blow 3): At this point, more complex features are added. Depending on the design, this could involve refining the head shape, starting to form threads, or creating any necessary grooves or slots.

5. Fourth Stage (Die 4 & Blow 4): Further refinement continues here. This station might focus on completing the threading process, adding final touches to the head, or creating additional features like knurls or chamfers.

6. Fifth Stage (Die 5 & Blow 5): This stage is often used for fine-tuning the dimensions and details of the fastener. It may involve perfecting the thread profile, adjusting the head dimensions, or adding any finishing elements required by the design specifications.

7. Sixth Stage (Die 6 & Blow 6): Additional fine adjustments are made at this station. This could be the final shaping of the head, ensuring all dimensions meet exacting tolerances, or adding any secondary features needed for the application.

8. Seventh Stage (Die 7 & Blow 7): The final blow completes the part. This might include the last touches on the threading, a final check on dimensional accuracy, or even a surface treatment if integrated into the machine. This ensures the part is fully formed and ready for use or subsequent processing steps like heat treatment or coating.
