Molding Window Derivation-Inputs

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.

The Molding Window analysis uses the following inputs:

Material

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.

Surface finish or gloss

The Molding Window calculation uses the surface finish (gloss) input to determine the ideal mold temperature.

The ideal mold temperature will be higher if you specify that the part must have a high gloss.

Note: Higher surface gloss may also require a longer cycle time.

Maximum injection pressure

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.
