Hydroforming question 1

[ornerynorsk]

I have a question for anyone who is experienced in hydroforming, please, no theorists, I need practical info.

What kind of fluid pressure would I need to hydroform the following part in a bladder-press: 5052-H32 alloy aluminum .080 sheet. Finished part size 46 inches long by 15 inches wide by 3.25 depth of draw. No irregular features except for a stiffening pocket on the major face approx 40 by 9 by .25 deep. 1 inch radius all corners.

Anybody who could shed some light, I would appreciate it. I'm very new to hydroforming.

I don’t have any data on specifics but the Verson Hydroforming presses operate between 5,000 PSIG &
15,000 PSIG.

Here is the website of a free booklet on hydroforming.
