Abstract

Abstract During gas-assisted filling, gas penetrations in symmetrical rib channels are found never symmetrical. The development of this unsymmetry is observed and its cause is analyzed. The system of gas penetrations in melt in symmetrical rib channels is found unstable. Symmetry is upset upon perturbation. Symmetrical gas-channel ribs in gas-assisted injection molded parts should be avoided.
