Aug 01, 2000 · Besides exerting a static pressure by the screw, the IM pressure can also be achieved by a backward-movement of the mould wall. 10 This injection compression has proven to be very useful in reducing the residual stress in the IM part, which will greatly reduce distortion. Both pressuring arrangements have the same effects on the cavity pressure.

Mar 26, 2020 · Flow rate and flow speed are cut in half at every runner branch. The point I am making here is, if youre injecting 14.1 in. 3 /sec of material into a mold, dont 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. . There is a direct correlation between
