碩士 === 國立成功大學 === 工程科學系 === 88 === By the experiments and computer simulation, the purpose of the study is to explore the effects of melt temperature, mold temperature and injection flow rate on the bonding strength of the solid-melt interface, the sequence of two-staged injection molding process by TPE and PS, and the formula of bonding strength dimensionless explaining its relation with the proportions of TPE. The results prove injecting TPE first and PS later has higher bonding strength and temperature. Producing an curved surface, contrasted to the flat surface made by injecting PS first and TPE later. The melt temperature is the primary factor of ex-periment much important than and then is mold temperature and injection flow rate. Those results could improve molding process of heterogeneity in two-staged injection molding. .
