The Flux, part result shows the average rate of heat flow across the mold/part interface during the cycle.
The surface flux is affected by the Mold-melt Heat Transfer Coefficients (HTC) values.
A lower HTC value represents a greater resistance to heat transfer between the polymer and the mold.
Use this result to find localized hot or cold spots, and determine whether they will affect cycle time and part warpage. An area of high heat flux indicates that there is a large heat concentration in this section of the tool.
If there are hot or cool spots, you may need to adjust the cooling channels.
