sprues

the sprue needs to be removed after casting.

ensure the sprue is properly aligned before pouring.

we use a sprue to guide the molten metal into the mold.

the sprue system plays a crucial role in the molding process.

after cooling, the sprue can be cut off easily.

a well-designed sprue can improve the quality of the final product.

inspect the sprue for any defects before use.

the sprue should be thick enough to handle the flow of metal.

adjusting the sprue length can affect the cooling rate.

we learned about sprue design in our engineering class.
