Webb26 mars 2024 · Flow rate and flow speed are cut in half at every runner branch. The point I am making here is, if you’re injecting 14.1 in. 3 /sec of material into a mold, don’t think the material is going into each cavity of a multi-cavity mold at the same 14.1 in. 3 /sec. In fact, for a 32-cavity mold, the flow rate in this example drops down to 0.45 in. 3 /sec. WebbThe gate serves as the entrance to the cavity and should be designed to permit the mold to fill easily. A cavity can have more than one gate. Gates should be small enough to ensure easy separation of the runner and the part but large enough to prevent early freeze-off of polymer flow, which can adversely affect the consistency of part dimensions.
