The Molding Window calculation uses information about the injection location and the size, shape, and thickness of the model to determine the lengths of the flow paths from the injection location to the points on the model's extremities.
A Molding Window analysis can only be run with materials that have a specified maximum recommended shear rate and a specified maximum recommended shear stress.
You can change the default value if your injection molding machine is capable of injecting at higher pressures. If a Molding Window calculation predicts that the injection pressure required to fill the part is greater than the maximum injection pressure, then that point on the display corresponding to the conditions used in the calculation will be red.
