Pouring system of fuundry

The pouring system in foundry refers to the method used to pour molten metal into the mold cavity in the casting process. It plays a crucial role in ensuring the quality of the final product. The pouring system includes several components:  1. Pouring Basin: This is where the molten metal is initially poured. It is designed to reduce the turbulence of the molten metal as it enters the system.  2. Sprue: This is a vertical passage through which the molten metal travels down, due to gravity, from the pouring basin.  3. Runner: The runner is a horizontal channel that connects the sprue to the gates. It carries the molten metal from the sprue to the mold cavity.  4. Gates: These are the final passages that control the flow of the molten metal into the mold cavity.  5. Riser: Also known as a feed head, this is a reservoir of molten metal provided in the casting to compensate for the shrinkage of the metal as it solidifies. The design of the pou…
