Experiment with gating systems in sand casting is performed before the construction of gating systems for the metallic mould. Correct Answer True

The gating and risering systems used in the permanent mould casting are very similar to that of the sand casting. In fact, to get the proper gating arrangement, it is desirable first to experiment with various gating systems in sand casting and then finally arrive at the correct gating system for the metallic mould.
