Molding Window Derivation-Calculation

The Molding Window analysis runs a series of quick calculations on the part, varying the processing conditions each time.

The processing conditions are only varied within their ranges of acceptability, as specified in the material information in the material database. The analysis uses these variables across their ranges:

• Injection time
• Melt temperature
• Mold temperature

The Molding Window analysis checks whether five conditions are acceptable for each of these calculations, using the following inputs:

• Material
• Part geometry
• Injection location
• Maximum injection pressure

Each calculation is represented by a single point on the Molding Window results, which is colored red, yellow, or green according to whether the following five conditions are acceptable or not:

• Injection pressure.

• Temperature at flow front.

• Shear stress.

• Shear rate.

• Short shot.
