Abstract: In this paper, automotive bumper with inner parting structure of injection molding process analysis and mould design was presented. A CAE finite model of bumper was developed by Moldflow simulation software. The effects of processing parameters such as filling time, volume and pressure conversion, injection time, weld lines, air traps, pressure distribution of the end filling, temperature of flow front and volumetric shrinkage at ejection on practical production of the automobile bumper were studied. The paper reviews various patents of injection mould for automobile bumper in the recent years, such as bumper materials, structure and bumper extension. The mould structure design was presented in detail, such as cool system, mould core pulling system, mould ejection system, and opening mould control system. With this kind of design and analysis, quality of part can be promoted maximally and molding period is reduced more. Mould cost on design, manufacture and maintenance can be reduced. The results proved that CAE technology for bumper molding and injection mould design has a strong guiding role.
