Answer» Correct answer is (b) False To explain: In permanent mould casting TECHNIQUE, metallic cores are not USED generally because the metallic cores cannot be COMPLEX with undercuts in the casting process. Also, the metallic core is to be withdrawn immediately after solidification; otherwise, its extraction becomes difficult due to its shrinkage in the mould. So, sand cores are mainly PREFERRED in this method for the casting process.
