In-Die Tapping Stamping

What is in-die tapping Stamping

In-die tapping is a manufacturing process that integrates thread tapping into stamping dies. It synchronizes punching, forming, and tapping operations during the stamping process, replacing the traditional two-step “stamping + secondary tapping” method. This process saves over 30% production time, reduces labor and equipment costs, and ensures precise alignment between threads and holes.

In-Die Tapping Stamping Process

During die design, tapping tools (taps) are integrated into the stamping die structure.

Process Flow:

The stamping press completes punching or forming of the sheet metal.

The in-die tapping unit (e.g., rotating tap) immediately processes threads on the hole.

The finished part is ejected with ready-to-use threads.
