Dealing with internal pressure in free hydraulic bulging: Predicting results with FEAFor hydraulic tube bulging, direct pressure control is the most commonly used process. Pressure control allows engineers to determine the correct capacity hydraulic system and, more importantly, prevent tube rupture. However, inflow control, or control of the volume of fluid inside the tube, theoretically could be another viable hydroforming process. Finite element analysis has shown that inflow control could allow engineers to more accurately predict deformation behavior and therefore enhance the hydroforming process.

Do you use checking jigs and fixtures?: An ounce of prevention is worth a pound of cureHow do you check tube fabrications to ensure they meet quality standards? Do you ship parts without checking them and hope that the next time the phone rings it isn't a prelude to a tirade from a disgruntled customer? Or do you check finished parts only to realize that your scrap rate is too high and wish you had checked them at earlier stages of the manufacturing process?
