How To Affect The Temperature Distribution In Blank And Blow Moulds - Comparison Between Fem Calculations And Measurement Results

Looking at the 3D-temperature distribution in blank and blow moulds used in the hollow glass making industry the understanding of the "correct" temperature field - mainly at the glass contact area - is of major importance. One key problem in making high quality containers is to achieve favourable contact temperature for the parison and also for the final bottle. This paper investigates the topic in the form of a numerical approach and temperature measurements inside the moulds.
