The effect of the design of the runner and the ingate on the rate and the quality of the flow is described. A comparison of flow properties in tapered, U-bent runner or runner with attached damper box and mono-hole or multiple-hole type ingate is discussed. The application of “pre-filling” method as a proposed pouring practice, by which aspiration and agitation are much rudused and the trapped air is washed away more quickly, is also outlined.
