Abstract

Une plaque (10) de résine est soumise à une déformation plastique par une mise en place sur et un alignement avec un moule femelle (11) et par une pression exercée par un moule mâle (12) venant de dessus, à la fois le moule femelle (11) et le moule mâle (12) étant chauffés par des dispositifs de chauffage et un agent de démoulage étant appliqué aux faces de moulage. Une pluralité d'ensembles de moules femelle et mâle (11, 12) agissent sur la plaque (10) de résine, laquelle est ensuite soumise à un rayonnement thermique puis refroidie par exposition à de l'air froid après que la pression thermique soit interrompue par arrêt du chauffage et libération de la pression. Lorsque la température s'abaisse pour atteindre la température ambiante, quelques minutes après l'arrêt de la pression thermique, le moule mâle (12) est levé pour le démoulage, formant ainsi des parties (10a) de lentilles moulées en une pluralité d'endroits sur la plaque (10) de résine.
