Estimation for Temperature Distribution of PET Preform Surface under Multiple Lamps

Abstract:

PET prefom surface temperature distribution is a key factor for getting the better quality of construction a bottle by stretch blow molding (SBM) machine. To get a better temperature distribution, different types of prefom under different number of infrared lamps heating conditions are worth to investigate the position of each lamp as well as its power intensity. In this study, we first try to use adaptive finite volume method to estimate the proper intensity of each lamp so that the combination strength will make good result about the temperature distribution. Then we make experiments to confirm each case. We have five, six, and seven heating lamps cases to present. With these estimations, we find that five lamps case can do equal quality about the temperature distribution comparing with six and seven lamps cases. This means that we offer a method for finding one saving energy way to produce PET bottle by SBM machine. A more detail analysis about inside PET bottle temperature distribution will be deliberated in future.
