| + | =====Interpretation of the curves===== | ||
| + | |||
| + | * ** Red curve**: The red curve represents the solid bed width. The curve starts at the location of the melt vortex formation with a value of 1. This means that the solid bed occupies 100% of the channel width at the start of the melting process. The solid bed width can increase as part of a compression zone or another reduction of the channel cross-section (start of a barrier zone, change to a 2-start screw zone, reduction of the channel gradient). If the melting model changes to disperse melting (e.g. due to a shearing or mixing section), the solid bed width curve ends here. | ||
| + | * ** Blue curve**: The blue curve represents the melt fraction. In contrast to the solid bed width, the melt fraction can only increase. If the melt proportion reaches the value 1 (=100 %), the entire plastic has melted. When switching to disperse melting, the melting speed can increase or slow down depending on the circumstances. | ||
