A Cooling Quality analysis simulates the transfer of heat from the plastic to the mold based on a concept of natural cooling.
This analysis identifies areas of the part where the part geometry, which is the shape and thickness combined, is expected to cause localized cooling problems, that is, areas of the part that require more cooling.
The part is considered to be embedded in a large metal block with no cooling channels and heat is assumed to be lost from the outer surfaces of the block. The Cooling quality result is derived from combinations of the Temperature variance and Cooling time variance results. These results are each divided into ranges that identify areas of the part in which the design could lead to poor or low quality of cooling (red), medium quality cooling (yellow) and high quality cooling (green).
The two results are evaluated for each area of the cavity. If both results in an area are acceptable, the area is green. If there is one unacceptable result, the area is red. In other cases the area is yellow.
