INTRODUCTION
The present work has been undertaken in order to introduce crystallization phenomena in the injection molding simulation software developed by Dupret and his group (1-7). A large variety of models can be used to describe the crystallization kinetics of polymers. In the framework of process modeling, Patel and Spruiell (8) recently presented a review of some of these models, including the most widely used Nakamura equation (9). These authors pointed out that all models currently available are inadequate in predicting non-isothermal crystallization kinetics on the basis of isothermal data. They also went out to suggest using nonlinear regression to ...
