To ensure the adhesion reliability of door sealing strip in the whole life cycle of the product, the Failure Tree Analysis (FTA) model of door sealing strip degumming was established considering the whole process of part design, manufacturing, assembly etc., to analyze various failure events, and 40 corresponding bottom events were identified, which were used to conduct Failure Mode and Effect Analysis (FMEA), to evaluate risk index and Action Priority (AP) of each degumming mode. 2 high priorities and 4 medium priorities for improvement were identified that were implemented to solve degumming.
