| Abstract: | The reason for shrinkage hole in light casting with isolated hot spot was analyzed. The shrinkage hole can be reduced and eliminated through increasing molding shell temperature and pouring temperature. The shrinkage hole can be decreased effectively through adopting different assembly tree schemes for different castings and adding round corner in casting also. |
