Starting from the fully bonded sealing structure of automobile door,this paper introduces door structural characteristics and common process layout in the actual production process.By analyzing the factors affecting the bonding effect and the relationship between the factors,the paper reveals the bottleneck of the current production process in further improving the bonding effect and reducing the risk of sealing strip failure,and proposes the application of plasma surface activation.For this process,the paper introduces the basic principle,and explores the potential of this process in improving sheet metal surface tension and bonding strength at high temperature through experiments.Finally,the safety of this process is confirmed by electron microscope observation that provides a new path for the automakers to further improve the bonding quality of door fully bonded sealing strip.
