Result after tool design and softening the part design (radii):
Thinning and tearing has been dramatically reduced.

The Challenge

Conceive a complex deep-drawn contoured part transfer die right the first time, while avoiding the timeconsuming traditional “cut and hope” method.

The Story

Doerfer faced the challenge of designing a transfer die for a deep, contoured part. In the past, the company’s engineers would have produced an initial concept design based on intuition and experience, built and run the die, and then gone through a process of re-cutting and re-running the die until it worked as intended. Instead, the company’s engineers used PAM-STAMP 2G software from ESI Group to simulate the drawing and forming process. The simulations identified thinning problems that the engineers were able t o correct directly on a software prototype, prior to building the die. The simulation was also used to determine the trim line.

The Benefits

“Using simulation instead of the conventional build and try method saved significant time and money on this project. The customer was very impressed with the result, and it helped pave the path for additional work.”
