Abstract

Bei einem Verfahren zum Herstellen von mehrlagigen Gegenständen aus einer Kunststoffschmelze, insbesondere in einem Spritzgiesswerkzeug, insbesondere von Vorformlingen mit einer Barriereschicht, wobei eine Viskosität, insbesondere eine Schergeschwindigkeit, der Schmelze ermittelt wird, soll die Viskosität, insbesondere die Schergeschwindigkeit, von zumindest einer Lage in dem Spritzgiesswerkzeug ermittelt und gegebenenfalls überwacht und/oder geregelt werden.
