  • Dieless drawing process of extruded non-circular aluminum alloy tubes with double hollow section  [in Japanese]

    FURUSHIMA Tsuyoshi , MANABE Ken-ichi

    Dieless drawing technique can thin down tubes by combining locally heating and tensile deformation of tubes without dies and tools. … In this study, the dieless drawing process is applied to non-circular 1100 and 3003 aluminum alloy extruded tubes with double hollow section for heat exchangers. … Fundamental deformation behavior of the tubes in the dieless drawing is investigated experimentally. …
