摘要

The method involves determining the viscosity, particularly the shear speed of a polymer melt in an injection mold. The viscosity of the melt, is optionally monitored or regulated. The preforms have a barrier layer, where the position of the melt is determined in a cavity. An independent claim is also included for a sensor for guarding a melt in a cavity.
