In the casting process, it is also important to use the foundry sand rationally. The compactness and thickness of the foundry sand should be adjusted according to the different parts and process requirements of the casting. For complex castings, the number and strength of the sand core can be appropriately increased to ensure the internal quality of the casting. At the same time, pay attention to controlling the pouring temperature and speed to avoid casting defects caused by excessive temperature or excessive Ahoɔhare.
