In-line process measurements for injection moulding control. In-line rheology and primary injection phase process measurements for injection moulding of semi-crystalline thermoplastics, using instrumented computer monitored injection moulding machines, for potential use in closed loop process control

Description

In-line rheological and process measurements are studied, during the primary injection
phase, as a potential aid to closed loop process control for injection moulding. The
feasibilities of attaining rheological and process measurements of sufficient accuracy
and precision for use in process control are investigated. The influence of rheological
and process measurements on product quality are investigated for semi-crystalline
thermoplastic materials. A computer based process and machine parameter
monitoring system is utilised to provide accurate and precise process data for analysis
