Résumé

Plastics are materials which show important volume variations when they undergo temperature changes. During the injection moulding process, polymer parts may shrink and so become unstuck from the mould walls. This leads to the formation of air gaps which may modify both the shape of the part and its cooling time. The cooling of such a polymer part was studied, taking into account key parameters such as thermal contact resistances, residual stresses, or PvT diagram. The results of the numerical simulation, using a coupled thermomechanical approach, were compared with experiments performed in conjunction with this work.
