Study on processs and impact strength for a rotationally molded truck fender

摘要

In this paper, a process for the rotationally molded truck fender was studied. The relationship between the part's impact strength and the heating temperature and time was analyzed. Furthermore, the influence factors for the impact strength were described by investigating the melt flow index (MFI) in the sample. Finally, the optimized process conditions for a truck fender were given.
