1.	Which of the following moulds is used in slush casting, in which mould is broken to remove the castings?(a) Copper mould(b) Iron mould(c) Bronze mould(d) Zinc mouldI had been asked this question during an online exam.I'd like to ask this question from Slush Casting in chapter Special Casting Techniques of Casting-Forming-Welding I
Answer» The correct choice is (c) Bronze mould Explanation: Bronze moulds are used in some CASES of the SLUSH CASTING when the better surface finish of the exterior PART is REQUIRED. When the metal hardens, the mould is broken to remove the castings. The inside of each cast retains molten texture while the exterior part is very smooth and shiny.
