Abstract
In this study, a integral type air vent duct body was proposed and flow analysis of injection molding using FEM was performed to improve performance deterioration caused by leakage defect of air vent duct body for automobile. The integral type of air vent duct body was developed in a new shape to be applied to new vehicles in domestic automobile manufacturing company. The leakage test was performed for performance evaluation and the flow analysis of injection molding was performed for new product. The proposed integral type air vent duct body was possible to eliminate the product defects caused by leakage in air vent duct body joint and to optimize the product injection molding process and to make multi product injection molding by the flow analysis. In addition, it was possible to provide application data for predicting feasibility of newly developed products and securing reliability.
