Tube-hydroforming experiments on an Al 7003 extruded tube
Journal of Materials Processing Technology, 2006Abstract Tube hydroforming (THF) is a valid alternative technique for the production of parts with enhanced performance in terms of resistance and feasibility of complex shapes. The present paper shows the results of the first tests conducted at the Brescia University Laboratory where experimental equipment, able to run THF experiments, is available.

Material Aspects of Tube-Hydroforming
SAE Technical Paper Series, 1999<div class="htmlview paragraph">Tube hydroforming includes several aspects related to the manufacturing process in particular pre-bending, part design, press and tooling, and also naturally the material to be formed. This is regardless of whether the low pressure technique is applied resulting in a constant perimeter or the high-pressure ...

Friction tests in tube hydroforming
Proceedings of the Institution of Mechanical Engineers, Part B: Journal of Engineering Manufacture, 2005The objective of this paper is to propose a friction test method to evaluate the performance of different kinds of lubricants and determine their coefficients of friction in tube hydroforming processes. A self-designed apparatus is used to conduct the experiments of friction tests.
