Abstract:	一般傳統的超塑成型製程，由於成型所需的時間過長，導致不符合經濟上的效益，為了尋求更好的製程方法來解決此問題，因此本論文提出針對快塑成型(Quick Plastic Forming, QPF)的製程，並且加上預沖壓輔助預成型應用於金屬手機外殼成型的構想進行探討，預期能藉由此製程更為縮短所需要的時間，並且突破成為更符合經濟較益的製程方法。本研究採用了一般的商用 AA5083-O 鋁合金快塑成型吹製手機殼，來探討快塑吹製成型，並加入預沖壓輔助吹製與一般無加上預沖壓輔助的快塑成型製程能力分析比較，分析是否更具有製作手機殼上的優勢。研究結果顯示出有使用預沖壓輔助的快塑成型，因為已預沖壓出一個接近成品的形狀，再進行吹製，更能夠節省所需的時間，且不需階梯式的吹製氣壓，即可吹出我們所需的成品，比一般無加上預沖壓輔助的快塑成型在時間上又更為優化。;In general, the conventional superplastic molding process, because the molding takes too long, leads to non-economic benefits, and in order to find a better process method to solve this problem, this paper proposes for Quick Plastic Forming (Quick Plastic Forming, QPF) ′s process, coupled with the idea of pre-punching-assisted preforming for metal phone casing molding, is expected to shorten the time required for this process and break through to become a more economical process. This study uses general commercial AA5083 -O Aluminum quick phone shell molding blown to blown molded plastic Fast explore, compare and analyzethe pre-stamped added auxiliary blowing plus pre-press and generally no faster assisted molding process capability, making phone analyzes whether more on the edge of the shell. The results of the study show that there is a rapid plastic forming using pre-punching, because a shape close to the finished product has been pre-punched, and then blown, which saves the time required and does not require a stepped blowing pressure. Blowing out the finished product we need is more time-optimized than the fast plastic molding without pre-punching aid.
