Abstract

The effect of processing parameters related to temperature on the interface bonding strength of automotive overmolding injection parts was investigated using moldflow simulation. In this study, the average depth of the melting layer, the melting time of the melting layer and the temperature of the melting layer on the basal body in the interface zone are used as a qualitative index, and the interface bonding strength of the tensile test and the results observed by scanning electron microscopy are used as a basis for verification. The results show that processing parameters related to temperature have a great influence on the interface bonding strength of parts. With an increase in melt and mold temperature, interface bonding strength is also strengthened. The most influential factor is the melt temperature of the second material.
