Determination of process parameters based on cavity pressure characteristics to enhance quality uniformity in injection molding

•Geometric dimension of molded part significantly depends on the V/P switchover point and holding condition.•This study proposes a simple least-squares regression-based approach for determining the V/P switchover point based on molded part quality requirement.•Multi-stage holding condition effective...
