Tubular hydroforming of advanced steel and aluminum alloys : an economic evaluation using technical cost modeling
Tubular hydroforming is gaining importance in the automotive industry by enabling parts consolidation, weight reduction and performance enhancement. While current automotive applications use almost exclusively mild steel, other advanced steel and aluminum alloys are being discussed for use in the …

Simulation and optimisation of the Interior High Pressure (IHP) manufacturing process using the Finite Element Method (FEA)
… work is to improve the integration of the hydroforming simulation into the simultaneous engineering process chain. Today the available simulation software packages are difficult to use and implement. The motivation of this work is to develop tools and methodologies for a fast and easy …

Investigation of manufacturing techniques and prototyping of the Smartcities Citycar frame
… frame, in the future, will be through tube hydroforming because of the optimization of strength, stiffness, and cost. It is recommended that the planned half-scale prototype be produced using composite layup techniques as the facilities for heavy machinery operations are not readily …

PLATE HEAT EXCHANGER IMPROVEMENTS WITH SHAPE OPTIMIZATION
… sealed at the edges, and then inflated in a hydroforming process. PPHXs have an economic advantage over other types of PHXs due to their simple manufacturing process. Additionally, the complex wavy structure of the pillow plates creates an excellent heat transfer medium and thus, if their …

An energy and environmental analysis of aerospace sheet metal part manufacturing
… flexforming (also known as a bladder press or hydroforming) dominate current aerospace production, and superplastic forming SPF is used when high formability is required. Machining is used extensively for very low volume production, such as prototyping. We find that the new RAFFT technology is …

Fundamental studies on the blow forming of polymeric micro-tubes and components
… of polymers and other forming processes such as hydroforming, process configuration and machine and, tools design consideration were defined. Investigations to miniaturize the design consideration concepts were conducted, which focused on the influences of tube dimensions (handling, flow stress, …
