7 Die 7 Blow Process

First Die & Blow: Cutting/Shearing

Task: Cuts the metal wire to the required length.
Outcome: Ensures uniform blanks for consistent processing.

Second Die & Blow: Heading/Upsetting

Task: Forms the head of the fastener by compressing or reshaping one end of the blank.
Outcome: Creates the initial form of the fastener's head.

Third Die & Blow: Extrusion

Task: Reduces or elongates sections of the workpiece to achieve specific dimensions or profiles.
Outcome: Adds features like undercuts or extended sections.

Fourth Die & Blow: Piercing/Punching

Task: Creates holes, slots, or other internal features within the component.
Outcome: Adds necessary internal cavities or holes.

Fifth Die & Blow: Trimming/Shaping

Task: Refines the final geometry of the part, removing excess material.
Outcome: Ensures the part meets exact specifications.

Sixth Die & Blow: Secondary Forming

Task: Performs additional shaping, such as rolling threads or adding grooves.
Outcome: Enhances the functionality and fit of the fastener.

Seventh Die & Blow: Final Forming

Task: Completes any remaining shaping, such as fine-tuning dimensions or adding final touches.
Outcome: Produces the finished fastener ready for use.
