Abstract:	本研究採用鋁合金AA5083 H18薄板材針對手機產品的金屬外殼進行吹氣成形，利用超塑成形熱壓機吹製一類似手機外殼的長方形開口盒，近年來由於3C產品的趨勢偏向輕、薄、短、小與其多變性，故本研究目標針對吹氣成型製程應用在手機產品上外，尚須達到成型速度快，成品外觀的小R角與微細表面的外觀需求。因此，本研究先以現有自製的模具墊塊做實驗，將成型條件分為兩組，一組為固定成型溫度，變更成型壓力與時間，另一組為固定成型壓力與時間，變更成型溫度，藉此找出成型溫度、成形壓力、成型時間與外觀R角表面微細紋路間的關係後，最後再以委託廠商製做有表面微細紋路造型的墊塊，配合調整後的參數實作並分析其成品成型性。In this study, we applied the blow molding process with the aluminum alloy AA5083 H18 material for the metal case of the cell phone products. Firstly, we use the superplastic forming machine to blow the rectangular opening box that similar to cell phone case. In recent years the trend of 3C products tend to be light, thin, short, small and variability, so It is the objective of this study the blow molding process applications on the mobile phone products, And it would need to achieve fast blow molding, small radius on the outline edge of the mobile phone products and 3D pattern appearance of the mobile phone product surface. Therefore, this study was started to experiment with the existing tooling hand-made plate. Firstly, the molding conditions are divided into two groups. One of group was fixed-forming temperature with the different molding pressure and time. Another group was fixed molding pressure and time with the different molding temperature. Base on the datum of the two groups to find out the relation by forming temperature, forming pressure, forming time, the radius of the outline surface and the fine line of the outline surface. Finally to apply the adjusted-forming condition we find with the vendor’s tooling plate to blow the finished product with fine line on the surface.
