2. Mold Coating Using specialized mold releases or coatings can help reduce friction between the metal and the sand, promoting a more uniform withdrawal of the casting and improving surface quality.

Stainless steel castings can not be welded more than three times at the same place. The distance between the castings on the edge of the weld zone, which includes the opposite weld zone, must not be less than the sum of the diameters of the two adjacent weld zones. After welding repairs, heat treatment is required in the original state.
