Abstract
In this study, we investigated the casting designs for fuel tank valves for LPG automobiles. The valves we studied have two cavities inside the part. There is inevitable air entrapment inside the cavities. In order to reduce this kind of casting defect, we carried out computer simulations of molten metal flow during the diecasting process of the target products. The main process parameters were the ingate position, product direction, and injection velocity. We also examined the possible use of vacuum diecasting. The position of the air entrapment was almost identical for all the ingate positions and product directions. We found that the change of the injection velocity affects the position of the air entrapment. In case of vacuum diecasting, the position of the air entrapment was similar to the previous cases, but it is expected that the air entrapment will be highly reduced in a real situation due to the vacuumed space.
