The purpose of hot runner is to convey the corresponding runner plastic melt to each gate. From the rheological point of view, it should be possible to keep hot runner balance natural, that there should be the same diameter from the injection nozzle into the flow path between the molded article and the length should be equal. Usually multimode cavity by mechanical balance runner manifold design, that is, from the injection molding machine nozzle into each cavity gate in front runner has the same length and diameter of the flow channel length.
Whether multi-cavity mold cavity bit layout is what the key is to ensure that a consistent quality of the melt lies. Well-balanced runner design is somewhat difficult, but a multi-level shunts and hot runner specification analysis, multi-material help to determine a reasonable mold melt channel layout.
