3. Warranty Coverage Many OEM parts come with a warranty, offering peace of mind in case of defects or premature failure. This warranty can often extend to the vehicle itself, ensuring that any issues arising from the use of original parts are covered. In contrast, many aftermarket parts may not offer similar warranty protection.

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. Effective facing sand is designed to minimize this penetration, preserving the mold shape and preventing unwanted inclusions in the final product. A well-constructed facing sand layer can create a barrier that helps to ensure a defect-free casting.
