Prohibited Gate Regions

When running a Gate Location analysis, there may be areas of the part where you do not want to have a gate positioned. Use the Prohibited Gate Region tool to specify areas where the Gate Location analysis excludes placing an injection location. This may be due to part or mold geometry, or it may be an area in which an injection location could cause a visible defect.

Prohibiting gate regions is optional, and must be done before running a Gate Location analysis. You can choose between two selection methods when using Prohibited Gate Regions, which works on both the Advanced Gate Locator algorithm and Gate Region Locator algorithm.

Tolerance Angle

You can activate this selection method by clicking a point on the model. Adjacent areas that meet at an angle that is less than the tolerance angle are included in the selection. The tolerance angle can be changed in the Tolerance setting.

The tolerance setting controls the amount of curve the selection algorithm factors in when selecting an area. The tolerance ranges from 0-89 degrees, with 0 being the lowest amount of tolerance and 89 being the highest amount of tolerance. A low tolerance level selects a narrower range of curve, resulting in a more precise selection. A high tolerance level selects a broader range of curve, resulting in a broader selection area. Modify the tolerance levels to suit your requirements.

The Tolerance Angle selection method is best suited for models that are thick and chunky, or for areas that have many curves and grooves.

Clipped

The Clipped selection method is activated by band-selecting the area that you wish to exclude as an injection location. When the Near Side Only check box is selected, only the areas on the visible side are selected. This selection method is best suited for models that are flat or angular.

The most efficient way of selecting prohibited gate regions is to use a combination of the two selection methods.

Multiple prohibited gate regions can be stored and displayed on the same model. Prohibited regions can also be saved with the model, which enables you to duplicate a model with its prohibited gate regions or export the model to Autodesk Simulation Moldflow Insight to view or edit the prohibited areas as nodes.

Note: When you run a Gate Location analysis in Autodesk Simulation Moldflow Adviser, you can export the model with its prohibited gate regions, read it into Autodesk Simulation Moldflow Insight and view them as prohibited gate nodes. You cannot, however, export a model with prohibited gate nodes from Autodesk Simulation Moldflow Insight and read it into Autodesk Simulation Moldflow Adviser.
