다국어 초록 (Multilingual Abstract)

Injection molding process is influenced by the injection conditions such as various thermal history and deformation processes that affect mechanical properties of the fabricated product. The design of the 29-inch TV backcover modified with the alteration of the thickness of special parts. Then the flow analysis was performed using the CAE S/W of the Mold Flow Company. In addition, the analysis was performed using the measured viscosity(loca1 database) at various shear rates and the results were compared with those using the standard database. In order to reduce the unbalanced flow of the molten resin, the thickness of the part, where the flow speed was slow, increased, while that of the part, where the flow speed was fast, reduced. As a result, the optimum condition based on the above modification of the special part of TV backcover is selected in terms of idealized flow pattern. In addition, the analyses based on the local database and the standard database showed no distinctive difference, although the measred viscosity was slightly higher and the temperature distribution was broader than by the standard database.
