Q4. Difference between open and close casting.
Open casting and close casting are two different methods used in the casting process.
Open casting is a casting method where the mold is not completely enclosed, allowing for easy pouring of molten metal.
Close casting, on the other hand, involves a fully enclosed mold, which requires a gating system for pouring the metal.
Open casting is commonly used for small and simple castings, while close casting is used for more complex and intricate castings.
In open casting, the molten m...read more
