| Abstract: | A new type of screw (type--BS4) without a metering zone in injection moldingmachine specially designed to processing HPVC was developed and studied experimentally.Based on the study, a simplified three-dimensional model was proposed for describingthe flow in screw channel, which was later computed by using two-dimensional finite el-ement method combined with an iteration scheme. A good agreement was found betweennumerical and experimental results. The results demonstrate that the screw developed hasgood performance in terms of the filling of the melt into the mold, pressure establishingrate and injection velocity. |
