Heat Transfer In Glass Container Production During The Final Blow

This study describes the cooling process in moulds during the production of glass containers. The heat transfer process is studied from the moment the product is in contact with the mould and has its final form. Special attention is given to the influence of blowing, characterised by the internal pressure and air flow, on the cooling process. The cooling of the glass is modelled by a one dimensional model. The boundary conditions on the mould surface and at the blow side are investigated. The study has led to a better understanding of the cooling process and to the identification of the most important parameters which determine the final blow process and the final product quality.
