This lecture is for beginners and experts who are interested in plastics process technology injection moulding and need to optimise processes.

Practice informs practice Module 01

Viscosity Curve (inmould viscosity)

Introduction and Chapter 01 (public) Length 24 min 18 sec

- The history of the relative viscosity curve

- An example of the difficulties of collecting data to create a viscosity curve in the past.

- The learning objectives of this module "Setting the maximum injection speed using the relative viscosity curve".

- What we can detect and influence in the injection phase.

- And methods of filling time determination

Chapter 02 - Length 24 min 24 sec

Topic Shear

- the influence of shear during melting

- the MFI or MFR

The apparent shear rate

Chapter 03 - length 22 min 12 sec

- The filling time

- The shear rate

- The creation of a Relative Viscosity Curve.

Chapter 04 -Length 11 min 51 sec

- The ideal relative viscosity curve

- Reference to tool optimisations and machine maintenance data (recognisable from the Relative Viscosity Curves.

Chapter 05 - Length 28 min 10 sec

- Relative viscosity curves created in practice with explanation and evaluation.

On one of the curves the possible tool optimisations and which maintenance data we can generate with the curves.
