摘要(中)

本論文主要針對以快塑成型(Quick Plastic Forming, QPF)的製程應用於金屬手機殼的外殼成型進行探討。實驗採用了一般的商用5083及超塑性的5083等不同性質的鋁合金鈑片進行不同時間下的手機殼快塑成型，藉由各種不同的機械性質及成型性測試，來探討快塑成型的製程是否具有製作手機殼的優勢，並評估哪種鈑材較適合作為手機殼快塑成型的材料。
研究結果顯示在單一次的快塑成型上影響能否完全成型的原因為模具的設計，而非材料本身的機械性質，且成型後各材料間的機械性質並沒有太大的差異。綜合研究結果可推斷，為了在經濟及時間上有效的利用快塑成型製程來製作手機殼的話，在材料的選擇上採用一般的商用5083鈑片即可。

摘要(英)

This thesis focuses on the application of quick plastic forming (QPF) process to the molding of metal cellphone shell. The experiments used different type of commercial 5083 and superplastic 5083 aluminum alloy sheet to carry out cellphone shell quick plastic forming at different times. Through a variety of mechanical properties and formability tests, to discuss the advantages of the quick plastic forming process to produce a cellphone shell, and which kind of sheet are more suitable as material for the quick plastic forming of cellphone shell.
The results show that the effect of one stage quick plastic forming on the complete forming is the design of the mold, rather than the mechanical properties of material, and the mechanical properties of material is not much difference before and after forming. Based on the above results, it can be inferred that in order to make cellphone shell efficiently using the quick plastic forming process in aspect of economy and time, commercial 5083 sheet is the better choose for material.
