Temperature profile, hot runner result

The Temperature profile, hot runner result shows the temperature profile from the center of the hot runner to the surface.

Using this result

The Temperature profile, hot runner result can be created as either an animation plot or an XY plot, and shows the melt temperature of the polymer at ejection. The temperature should be uniform across the hot runner. When the result is created as an XY plot, the X-axis value of -1 represents the surface of the runner and 1.0 represents the center. The center of the runner will most likely be above the transition temperature because the cross section of the runner is generally much larger than that of the part. Because of this, the cycle time should be based on the temperature profile of the part rather than that of the runner.

Things to look for

  • Check for elements that have a very high temperature, as this may limit the cycle time.
