Answer» Correct choice is (d) Labour intensive Best explanation: In sand casting process, the sand is rammed by using the rammer and then the cope and drag box are used as a moulding box to prepare the mould. In this process, much of time is spent and it requires too much labour work. So this method is normally used for small scale production for producing small size castings. |
