Zone (Molding window) result

The Zone (Molding Window) result shows the optimum mold and melt temperatures and the injection time required to produce an acceptable part for a specific material within the constraints of the mold design.

This result is generated by the Molding Window analysis and shows the following three colored zones:

Using this result

Green–the preferred molding window

If you use the process settings represented by a green area, there is a higher chance the part will mold well.

If the molding window includes a green area but it is very narrow, try to improve it. A narrow green area indicates that if the processing conditions vary, even by a small amount, the part may be unsatisfactory. When parts are being made, it is likely that some variation in conditions will occur so try to ensure that the molding window is robust, that is, it has a fairly wide green area.

Yellow–a feasible molding window

If you use the process settings represented by a yellow area, you will probably be able to mold the part, but its quality may not be high.

An all-yellow molding window indicates that there is no particularly good combination of process settings for this part with this injection location and material. Depending on how strict the quality requirement for the part is, you may need to move or add another injection location, change the material, or change the part geometry.

Note: If the Molding window result indicates that a preferred molding window does not exist, a feasible molding window may still be possible.
Red–no feasible molding window

An all-red molding window indicates that there is no good combination of process settings for this part, with this injection location and material. You must move or add another injection location, change the material or change the part geometry.

Things to look for

Review other analysis results and look for defects that will help you choose new or different injection locations.

Note: The predicted process settings might result in molding or quality problems even after a Molding Window analysis has been performed. This is because the Molding Window analysis provides only a quick, preparatory suggestion, which is not intended to replace a full analysis.
