| dc.description.abstract | 快塑成型技術通常應用於製作汽車鋁鈑件，來達到大量生產的目的，而本論文主要探討以快塑成型技術應用於手機外殼零件製造之可行性。實驗以1mm SP5083 鋁合金鈑片為實驗材料，通過不同製程模式與調整製程參數的方式，進行縮短製程時間之實驗，並量測成型後鈑片厚度分佈情形，比較不同模式下厚度分佈的差異。製程模式分為三類，是以模具夾持的方式進行區分，夾持模式1為直接夾持至指定壓力，夾持模式2為隨著吹氣壓力調整夾持壓力，夾持模式3為兩階段夾持，第一階段以輕微夾持方式預吹，接著第二階段夾持到指定壓力。製成時間最初以90秒進行實驗，而後慢慢縮短至60秒，不同實驗參數則會影響鈑片成型度。厚度量測分為橫切面與角隅切面，以手機殼來說厚度分佈越均勻越好。 | zh_TW |
| dc.description.abstract | Quick plastic forming technology is usually used to manufacture the aluminum parts of automotive to achieve the goal of mass production. This thesis focuses on the feasibility to use quick plastic forming technology to make the shell of cellphone. The experiment material is 1mm SP5083 aluminum alloy sheet, and through the different ways of process mode and adjusting the process parameters to shorten the process time. Then measure the thickness of formed sheet and compare different mode of thickness. There are three types of process mode which distinguish by the die clamping type. Mode 1 is directly clamping to the specify pressure. Clamping pressure changes with blowing pressure in mode 2. Mode 3 is two stage clamping mode. The first stage is clamping slightly to pre-blowing, and the second stage is directly clamping to the specify pressure. The initial process time of experiment is 90 seconds and slowly reduced to 60 seconds. Different experiment process parameters will influences the completeness of sheet. There are cross section and corner section in thickness distribution. The more uniform the thickness distribution is, the better the shell of cellphone is. | en_US |
