A methodology is presented to estimate cavity melt temperatures and part weight in the injection molding of amorphous thermoplastics. The approach uses measurements of cavity pressure near the gate and surface temperatures at three sensor locations. The surface temperature data with a heat conductio

## Abstract The selfβinterference flow (SIF) of a melt in a cavity during injection molding is introduced. It comes from two streams of the melt being split by a patented mold gate called a twin gate. The effects of this flow on the static and dynamic mechanical properties, thickness distribution,
