For the development of an electric molding machine with low energy, high performance, and high reliability, characterization, finite element analysis and fatigue strength analyses were performed. Strain was measured by strain gages bonded on electric molding machine and compared with stress analysis results using I-DEAS. The analyses showed good agreement with test results. By means of the comparison, we could draw an adequate boundary condition for the stress analysis of the components of electric molding machine. Additionally, we could verify the load distribution mechanism among the parts. The life prediction results for tie bar and thread zone showed infinite life.
