Abstract

On préchauffe une ébauche (11) en polyéthylène terephthalate (PET) possédant un corps cylindrique coiffé (13), une partie supérieure filetée et une collerette (19) afin de ramollir le PET. On place l'ébauche (11) dans un moule fendu (26) dont les parois sont chauffées pour atteindre une température située entre 150 °C et 177 °C. Une tige d'étirage (35), introduite à travers la partie supérieure de l'ébauche (11), étire cette dernière (11) axialement jusqu'à ce qu'elle atteigne la longueur du produit final (49). L'ébauche (11) est dilatée au moyen d'air ambiant comprimé et moulée contre les parois (27, 29) du moule (26). On évacue l'air et on injecte de l'azote sec à une température inférieure à -50 °C dans l'ébauche moulée (47) afin de la purger et de la refroidir, tout en maintenant une pression d'au moins 520 kPag. On maintient l'ébauche moulée (47) contre le moule (36) afin d'effectuer le recuit des surfaces intérieure et extérieure de ladite ébauche moulée (47). On interrompt l'apport d'azote et on ôte du moule (26) le produit fini (49).
