This usually still results in unbalanced filling and is not a recommended design.2 “H” Pattern Runner This type of runner delivers a geometrically balanced type of fill, and is recommended for most multi-cavity tools. Only naturally balanced runner systems (“H” patterns) are recommended. The blue arrows show the flow of material in figure 51.
