How a part cools has a dramatic effect on part quality and dimensional accuracy. The ideal part is of uniform thickness cooled in a mold of uniform temperature. This assures that the part shrinks at the same rate in all directions. As we move away from the ideal conditions, we induce variable shrinkage in the part.
The areas that freeze first will be pulled on by the areas that shrink last. This induces molded in stress and warp in the part. The cooling plots show areas where this will occur. The cooling quality plot highlights the problem areas in the part. The Surface Temperature Variance and the Freeze Time Variance plots show the magnitude and areas […]
