碩士 === 輔仁大學 === 科技管理學程碩士在職專班 === 104 === Metal injection molding (MIM) is one kind of process technology which is widely applied to electronics, medical, automotive, mechanical tool, aerospace, military, commodity, and so on. Under high temperature (about 1300 ℃) of vacuum sintering, parts would be deformed due to raw material and the size of objects. Sizing process will be next process to solve the problem of deformation in order to meet dimension tolerance request. The situation of labor shortage in tranditional industry is becoming worse. Therefore, introducing into the development of automation can not only enhance the working efficiency, but also train the staff expertise toward the development of industry 4.0. This study is to research the feasibility of the sizing process of MIM on the material handling automation. Design materinal handling contruction as per the sizing tool of the object. Plan two forms of material handling automation by sliding & mechanical arm. And, draw up the operating flowchart to anslyse working hours between manpower and machine. If working efficiency could be raised, evaluate the expection of efficiency by cost-benefit analysis. If the result of evaluation – NPV is larger than 0, that could be proved this material handling automation is worth investment. Then, implement the program to create a real machine and prove the performance. The empirical results can meet the expectation of working efficiency and cost benefits analysis. The NPV of material handling automation by sliding & mechanical arm are NT$ 5,844,712 & NT$ 3,805,577 which are proved very worth investment. Therefore, introducing into the automation can not only indeed streamline manpower but also reach the research of purpose. That’s a reference to MIM manufacturing enterprises who would like to promote the automation in order to enhance the core competitiveness of enterprises.
