Experimental Study of the injection stretch/blow molding process

Abstract : The performance of Poly(Ethylene Terephtalate) bottles produced by the injection stretch/blow molding process depends on three main variables: the initial preform shape, the initial preform temperature and the balance between stretching and blowing rates. In order to characterize process parameters, experiments have been performed on a well instrumented mold. In addition, preform free inflation have been processed and a simplified model of an air volum free blowing has been developed.
