Since Apple achieved success in metal structure, more and more Computers/Communications/Consumer corporations choose to follow Apple’s path. They also utilized metal cosmetic parts to manufacture their smartphones, notebooks, tablets, etc. In addition, as characters of metal cosmetic parts are high strength, high heat resistance and EMI protection, fewer materials and heat dissipation components are consumed during the manufacturing process. Therefore, to achieve the goal of thinner and lighter product design. The study selected the top 3 capital of Metal Casing Suppliers in Taiwan based on the period of year 2015 to 2017 as the research objects, including Foxconn Technology Co., Ltd., Catcher Technology Co., Ltd. and Casetek Holdings Limited.
