Further, when the embedded metal fitting is cast-in-casing, the reference surface is protected by a lid member so as not to be damaged, and is removed after shot peening. Not only does this lid member prevent damage to the reference surface, but it is also a mounting bracket (cast part) when the mounting bracket is cast into a casting part.
It also has the role of holding in the pouring sand.
