The Frozen layer percentage, part (bottom) result shows the thickness of the frozen layer on the bottom side of the element.
Use this result with the Frozen layer percentage, part (top) result to determine if the part froze uniformly.
Using this result
Ideally, the frozen layer thickness should be the same for both top and bottom surfaces to help achieve uniform cooling.
The amount of the wall thickness which must be frozen before ejection will depend on the part 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 fraction of the entire element thickness. In the following diagram, the top frozen layer thickness is 0.5 (the bottom frozen layer thickness is 0.2).
Things to look for
- The same frozen layer thickness for the top and bottom surfaces.
- Non-uniform cooling.
