Problem 1 Suppose we want to cast a magnesium bar 20x20x45 mm³. We are to use a mid gating (exactly at the parting line) system with two runners and multiple ingates (no bends in runner), a top riser of 1:1.2 (D:H) ratio, and the bar lying down. The pouring cup to be used has a height of 10 mm. What would be the riser dimensions for this casting? Use the JB Caine Method (a, b, c = 0.10, 0.06, 1.08). If the choke area is 20 mm?, how long would the pouring time be?
