<p> Capillary shaping is a novel manufacturing technique for obtaining complicated shaped aluminum frames used for optimizing weight and design of car body structure. This process requires faster pulling rate for higher productivity and mechanical properties. However, strong air cooling causes breaking of the melt column which results in the interruption of the pulling process. In this study, we carried out water model experiments and capillary shaping of cylindrical specimens under strong air blowing conditions for investigating the mechanism of the melt column breaking. We found that melt column braking occurred due to negative pressure arising from air blowing in the hollow specimens. We successfully increased the pulling rate using strong air cooling under controlled air pressure in the hollow specimens.</p>
