WebApr 22, 2024 · Find the mass of the liquid metal filling the mould cavity, gates and risers when the volume ratio is 15 and the casting volume is 10. This implies that; K v = Volume Ratio = 15 V = Casting Volume = 10 G = K v x V G = 15 x 10 G = 150 Therefore, the mass of the liquid metal filling the mould cavity,gates and risers is 150. WebThere are six steps in this process: Place a pattern in sand to create a mold. Incorporate a gating system. Then the pattern is removed with the channel plug, leaving the mold cavity. Fill the mold cavity with molten metal. Allow the metal to cool. After the metal has solidified and cooled, break away the sand mold and remove the casting.
