metal casting in sand_

3. Reducing Metal Penetration One of the potential issues in casting is the penetration of molten metal into the sand mold, leading to defects like metal penetration or drop-out of sand particles.

A well-constructed facing sand layer can create a barrier that helps to ensure a defect-free casting.
