MoldingMolding ParametersParameters

Complete Moldflow materials database.

More than 7,500 plastics materials. Molding conditions can be

automatically determined.

Uses the material suppliers recommendedmold and melt temperature.

Automatically identifies an injection time that

minimizes the pressure to fill the component

and maintain an acceptable flow fronttemperature.

Best Gate Location AnalysisBest Gate Location Analysis

Analyzes various locations on the

model for its suitability as an injectionpoint.

The most suitable areas are rated as

best, and the least suitable areas of themodel are rated as worst.
