Abstract
During gas-assisted filling, gas penetrations in symmetrical rib chann els 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 injec tion molded parts should be avoided.
