Volume change result

The Volume change result shows the change in runner volume from the original design to the optimized design.

The runner volume change is displayed as a percentage of the original runner volume.

Using this result

The main purpose of the Runner balance analysis is to minimize the size of the runners, while ensuring that the fill pattern is balanced and the packing pressure is uniform. This will minimize the runner volume and, therefore, the amount of material required to make each part.

The Runner balance analysis should indicate a negative change in shrinkage (%), which means the runner has gotten smaller.

Things to look for

Review the Fill time, Pressure, Pressure at injection location, and Pressure at end of fill results to confirm the following for your optimized part design:
  • Ensure runners are balanced and the part will fill evenly.
  • Ensure packing is uniform.
  • Maintain an acceptable pressure magnitude.
