Method for manufacturing plastic hollow bodies by blow molding, involves setting measurement in relation with reference value, where deviation starts between measurement and reference value for preform

摘要

The method involves setting measurement in relation with a reference value. The deviation starts between the measurement and the reference value for a preform (5). The spatial arrangement of a significant profile point and the viscoelastic flow characteristics of the plastic melt are determined on the basis of a numerical model. The spatial arrangement of a profile point is compared with a reference position.
