| Outline of Final Research Achievements |
The mass fabrication technology of long ultrafine tubes for advanced medical and electronic information devices was examined. In this study, the use of a technique called fluid mandrel drawing and a drum drawing machine was proposed. We clarified that long ultrafine tubes with the desired properties, namely, a diameter of 0.2 mm, a thin wall, and good surface characteristics, can be mass-fabricated by the proposed method in a stable manner. From the results of finite element analysis, it was found possible to estimate the wall thickness of drawn tubes. We also clarified that the proposed method can be used to fabricate narrow micro-heat pipes to release the heat from high-functionality electronic information devices, ultrafine tubes for patient-friendly painless injection needles, surgical suction pipes, and magnesium tube stents.
