Warpage optimization based on moldflow and full factor
experimental design

Abstract: Taking the composite tailgate upper trim panel of a new energy vehicle PP+LGF40 as an
example, in the early stage of mold flow analysis, the most appropriate gate scheme was obtained first, and
then the key factors affecting the deformation, such as material temperature, holding pressure and holding
time, were considered. In this paper, full factor experimental design is used to analyze the data and obtain
the best process parameters. After the mold is opened, the mold flow analysis parameters are input into the
actual situation, and the consistency between the mold flow and the actual situation is compared. It is found
that the mold flow analysis can predict the deformation of the product, but there is a slight difference in the
value, the difference is about 0.5 mm, which can guide the mold opening of the product.
Key words: Moldflow; full factor experimental design; tailgate upper trim panel; warpage deformation
