Which operation is NOT typically performed after removing a casting from the mold?

The operation that is typically not performed after removing a casting from the mold is melting. Once the casting has been successfully removed from the mold, it is already in a solid state, having formed during the initial pouring of molten metal into the mold. Melting is the process that occurs before casting when the metal is in its liquid form. Therefore, this operation is not relevant to the subsequent steps taken after the casting is complete.

Trimming, core removal, and surface cleaning are all common practices following the removal of a casting. Trimming involves cutting off any excess material or flash that may have formed around the edges, ensuring that the casting conforms to the desired specifications. Core removal refers to the extraction of any internal cores used in the mold to create hollow sections in the casting. Surface cleaning is often performed to remove any residues, sand, or imperfections from the surface of the casting, preparing it for further processing or finishing.
