I made a good bend when testing a short piece of tube,its about 12 inch
but when i tested with 30 inch tube,i have wrinkes.
CLR = 2D,tube OD = 30,1mm thickness,titanium grade 2.
1.mandrel and wiper is at good location because test bend is fine.
i think the problem is at pressure die ,but dont know where to check.
I have adjust pressure at pressure die to maximum level but no luck
there is no slippage at clamp die
