The empirical verification f the mathematical model proposed by theauthors for the description of flow of molten polymers through ring sprue ofthe injection mould during mould filling period has been presented. The adequacyof the elaborated model to the analysis of flow of polymers in sprues andrunners of the injection moulds has been stated. This model permits thecalculation of pressure drop in the sprues with a much higher accuracy than thecomputational model on the generalized Hagen-Poiseuille equation.
