In the last years many researchers were concentrating to develop and design new unconventional metal forming processes. Among such new technologies, tube hydroforming was proved as one of the most promising. Geometries of the tube and die were found to have significant effects on the hydroformed part. Based on the mathematical models, which describe the effect of the geometrical factors on bi-layered tube hydroforming, a multi-response optimization study was proposed in this paper with the aim to achieve different quality objectives for two different criteria. The optimal geometrical factors of bi-layered tube hydroforming combinations were tabulated and discussed.
