Product Description Basic layoutsThere are three basic runner system layouts typically used for a multi-cavity system.These layouts are illustrated in Figure 1 below.l Standard (herringbone) runner systeml "H" bridge (branching) runner systeml Radial (star) runner systemFIGURE 1. Basic runner system layoutsBalanced vs. unbalanced layoutsBalanced layoutsThe "H" (branching) and radial (star) systems are considered to be naturally balanced. The naturallybalanced runner provides equal distance and runner size from the sprue to all the cavities, so thateach cavity fills under the same conditions.Unbalanced layoutsAlthough the herringbone is naturally unbalanced, it can accommodate more cavities than itsnaturally balanced counterparts, with minimum runner volume and less tooling cost. An unbalancedrunner system can be artificially balanced by changing the diameter and the length of the runner.Automatic balancingRunner System LayoutRunner balancing can be accomplished automatically with C-MOLD runner balancing analysis.
