%Volume of gas:XY Plot result

The %Volume of gas:XY Plot result shows the volume percentage of gas in the cavity during the filling and packing phases of the analysis, displayed on an XY plot of percentage volume versus process time.

This result is generated from Gas-assisted Fill+Pack analysis using Midplane or 3D analysis technology.

Using this result

The %Volume of gas:XY Plot result shows how fast the gas is entering the cavity during filling, and how fast the gas is compensating for the polymer volumetric shrinkage during the packing phase of the analysis.

This plot can be used to determine the optimal gas injection time, as indicated below.

Things to look for

• When the plot levels off, or when the data points are closer together, this indicates that increasing the gas injection time would not increase the gas penetration any further.
