(6) The influence of casting temperature: the higher the casting temperature, the greater the shrinkage rate, the lower the casting temperature, and the smaller the shrinkage rate, so the casting temperature should be appropriate.

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.

1. Enhanced Engine Efficiency A clean and well-sealed spark plug cover can improve the overall efficiency of your engine. It ensures that the spark plugs function optimally, leading to better fuel combustion and improved performance.
