Evolution of the Research on Simulation of Parison Forming of Blow Molding

A general state of development and research about simulation of parison ofblow molding is given in this paper.For the parison forming,a explanation aboutspecialized method and theory basis of numerical simulation adopted by researchersin China and abroad is given.The great emphasis is put on the method of ANN.The paperindicated that the parison forming is the key of the blow molding,and is a stage ofprocess influenced by all kinds of factors such as polymer material property,meltingtemperature,condition of process and so on.Therefore a lot of works still need to bedone in the future.
