Comparison of Axial Feed Options in Tube Hydrostatic Forming Process to the Quality of 60° Y-shaped Components Made of CDA110 Copper

Tube hydrostatic forming (THF) is one of the fascinating forming processes, applied to produce hollow tubes through a high-pressure fluid source inside the tube. Tubular products manufactured by this method have demonstrated many advantages such as achieving complex structure, stiffness, higher mechanical properties, reduced weight, low springback. Their diversity and wide application in key sectors such as the automotive, ship-building, aerospace, and oil and gas industries increasingly demand higher standards of quality. Therefore, this paper presents a study on three axial feed options in the THF process to fabricate components with complex and asymmetrical structures—60° Y-shaped CDA110 copper material components. The study was carried out on the basis of numerical simulation using Abaqus software to evaluate the quality of components to be shaped through 5 criteria including The profile of component, Section thickness, Total and effective protrusion height, Mises equivalent stress, and Plastic deformation components. Research results can be applied in product design and more efficient process design, optimized computation, and control of input and output parameters for more cost and time savings in the trial and error stage, quickly bringing quality products to market.
