| Abstract: | This paper analyzed the characteristics of car A-pillar decoration trim parts,and discussed the mold design and injection molding key points of over-molding with metal inserts.Gating layout and structure of the filling system were optimized by Moldflow analysis.Special mechanical structure like“rib-boss+cashew shape blade ejection”was adopeted to ensure good positioning of metal insert and smoothly departing during the over-molding injection.Our mold design guaranteed product quality and enhanced injection production stability. |
