The primary purpose of sprue in casting molds is to help feed the casting until all solidification takes place.
Feed the Casting Until Solidification Takes Place:
- The sprue is a channel or passage that allows molten metal to flow from the pouring basin to the casting cavity.
- It serves as a conduit to deliver the molten metal to the casting and to maintain a continuous supply of molten metal until the entire casting is solidified.
- The sprue ensures that the molten metal reaches all parts of the casting, filling it completely, and preventing any voids or defects.
Feed the Casting at a Consistent Rate:
- The sprue is designed to provide a controlled flow of molten metal into the casting cavity.
- The rate of feed must be consistent with the rate of solidification to prevent issues such as shrinkage defects or incomplete filling of the mold.
- By regulating the flow of molten metal, the sprue helps ensure that the casting solidifies uniformly and without any defects.
Act as a Reservoir:
- The sprue also acts as a reservoir for molten metal.
- It holds a certain volume of molten metal, which can compensate for any shrinkage or contraction that occurs during solidification.
- This reservoir of molten metal in the sprue helps to maintain a continuous flow of molten metal into the casting until solidification is complete.
Feed Molten Metal from Pouring Basin to Gate:
- The pouring basin is the area where the molten metal is initially poured into the mold.
- From the pouring basin, the molten metal flows through the sprue and then into the gate, which is the narrow opening that leads to the casting cavity.
- The sprue acts as a conduit that connects the pouring basin to the gate, allowing the molten metal to flow smoothly and evenly into the casting cavity.
In summary, the sprue in casting molds serves to feed the casting until all solidification takes place. It ensures a controlled and consistent flow of molten metal into the casting cavity, acts as a reservoir to compensate for shrinkage, and connects the pouring basin to the gate for smooth and even flow of molten metal.
