Abstract

Die Erfindung betrifft ein Verfahren zur Herstellung von Behältern (2) aus einem Rohmaterial (5), insbesondere Polycarbonat, bei dem das Rohmaterial (5) in einem Extruder (4) plastifiziert und durch einen Heizkanal (7) in ein Spritzgußwerkzeug (9) für einen Vorformling (14) eingespritzt wird. Anschließend wird der Vorformling (14) in ein Formgebungswerkzeug (24) eingesetzt und unter Zufuhr von einem Druckmedium in einen Innenraum des Vorformlings (14) dieser auf das gewünschte Volumen aufgeweitet. Darauf wird der Behälter (2) aus dem Formgebungswerkzeug (24) entnommen. Ein Kern (15) und eine Kavität (11) des Spritzgußwerkzeuges (9) werden zur Herstellung des Vorformlings (14) auf unterschiedlicher Temperatur von über 70 °C gehalten. Die Kavität (11) wird auf einer höheren Temperatur gehalten als der Kern (15).
