| Outline of Final Research Achievements |
In this study, we designed and developed an injection mold capable of melt flow control and induction heating and cooling by controlling the melt flow direction using a rotary core pin, and we attempted to improve the appearance and mechanical strength of the molded product. This mold was used for molding long and short glass fiber reinforced polypropylene. As a result, by controlling melt flow and induction heating, smooth surfaces with minimized projection of glass fibers to the molded product surface were obtained, and bending strength was found to improve, thus demonstrating the effectiveness of this mold. Furthermore, this mold was used for molding polypropylene containing aluminum flakes. It was clarified that weld lines with inconsistent coloring can be reduced by controlling the melt flow while heating the mold.
