| Summary: | 碩士 === 國立中央大學 === 機械工程研究所碩士在職專班 === 100 === 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.
