Abstract

An einer Schnecke (18) einer Spritzgießmaschine (1) ist ein abgestufter Schneckengang (28) ausgebildet. Der abgestufte Schneckengang (28) ist ein Schneckengang (21), bei dem ein stufenförmiger Stufenabschnitt an seinem oberen Abschnitt (29) ausgebildet ist. Der obere Abschnitt (29) des Schneckengangs (21) umfasst einen Abschnitt (31) mit großem Durchmesser auf einer stromaufwärtigen Seite und einen Stegabschnitt (32) auf einer stromabwärtigen Seite. Wenn ein Spaltverhältnis m zwischen einem Spalt H1 zwischen dem Stegabschnitt (32) und einer Bohrung (35) des Heizzylinders (17) und einem Spalt H2 zwischen dem Abschnitt (31) mit großem Durchmesser und der Bohrung (35) als H1/H2 definiert ist, wird das Spaltverhältnis m so gewählt, dass es 2,3 ≤ m ≤ 6,4 beträgt.
