| Abstract: | A mathematical simulation of blow-molding cycle of the axisymmetrical parison has been proposed by introducing an appropriate constitutive relation. The dynamical analysis of the parison during the blow-molding process was done by considering geometrical parameters of the blow-molding machines. A method for verifying the rate of shape changing for the parison by measuring the pressure inside the parison during the blow-molding process was proposed. |
