A one‐dimensional model of unsteady state heat conduction has been applied to the cooling and solidification of a polymer in a blow molding process. The approach includes a temperature‐dependent specific heat term to account for latent heat effects during the phase change. The model is used to predict temperature profiles in a thick‐walled component of high‐density polyethylene. These profiles lead to a clearer understanding of the heat transfer process. It is further shown that these temperature distributions can be used to study the influence of the major process variables upon the cooling of the molded component.
