Abstract

Die Erfindung betrifft ein Verfahren zum Herstellen von Formteilen (2) aus Kunststoff mit zumindest einem von Wandteilen (3) umgrenzten und in sich geschlossenen Hohlraum. Die Aussenhaut (4) wird schlauchförmig kontinuierlich oder diskontinuierlich hergestellt und mit einer Temperatur zwischen der Plastifizierunstemperatur und der Glastemperatur in einen Formhohlraum (11) einer Blasform (8) eingebracht. Die Aussenhaut (4) wird zumindest bereichsweise an Formflächen (12) der Blasform (8) durch den Aufbau einer Druckdifferenz zwischen dem Hohlraum (5) des Formteils und einer äusseren Oberfläche desselben, insbesondere mittels Unterdruck, angelegt, Zwischen der Blasform (8) und dem Hohlraum (5) des Formteils (2) wird zumindest eine Zu- und (28) Ableitung (58) hergestellt. In den Hohlraum (5) des Formteils (2) wird zumindest bereichsweise zwischen der Formfläche (12) der Blasform (8) und der äusseren Oberfläche (13) des Formteils (2) über Poren eines porösen, die Blasform (8) bildenden Werkstoffes abgesaugt.
