Polymer skin fraction at end of process result

The Polymer skin fraction at end of process result shows the thickness fraction of the polymer skin at the end of the cycle.

The Polymer skin fraction at end of process result is generated from a Gas-assisted Fill+Pack analysis using Midplane analysis technology.

Using this result

The Polymer skin fraction at end of process result provides you with a good approximation of the extent of gas permeation through the part.

The maximum value is 1, which corresponds to a region of solid polymer. A value of less than 1 indicates a region hollowed out by injected gas.

This result is equivalent to the last frame of the Polymer skin fraction result.

Note: It is a good idea to deselect the Nodal averaged option when viewing this result. A plot will be shown where each element is assigned a single color, however, elements where gas permeation has occurred are easier to identify.

Things to look for

• A value of 1.0 indicates that the element is completely filled with polymer. Regions with a value of less than 1 indicate a region hollowed out by gas, possibly due to a large gas injection pressure.
