The Percentage frozen layer, cold runner result shows the thickness of the frozen layer on the cold runner surface at the end of the analysis.
Using this result
Ideally the frozen layer thickness on the outer surface of cold runners should be uniform to help achieve uniform cooling .
The amount of the wall thickness which must be frozen before ejection will depend on the part's stiffness, the degree to which the part is resisting ejection (due for example to mold finish or overpacking) and the design and position of the ejector system components.
Note: This result is a percentage of the entire part area thickness. In the following diagram, the top frozen layer thickness is 50% (the bottom frozen layer thickness is 20%).
Things to look for
- Non-uniform cooling.
