Quick Molding Analysis

Run a quick injection molding analysis to get initial data on the practicality of your model setup.

Run Quick Analysis

Define run options and execute a quick analysis to understand predicted flow pattern and sink marks data during molding.

Complete the model setup before running an analysis.
Note: Analysis results are saved in the folder specified in your Preferences settings under Molding > Analysis > Run Options.
  1. Click Run Quick Analysis on the Quick icon.

  2. Define the parameters for the analysis.
    Tab Option Description


    Flow Enable this option to run a flow pattern analysis.
    Max injection pressure Enter the maximum pressure that your injection machine can produce.
    Max clamping force Enter the maximum force required to keep the mold closed during the injection process.
    Mold temperature
    Enter the initial temperature of the mold.
    Note: This field can be filled via the Molding Window.
    Melt temperature Enter the melt temperature of the material.
    Note: This field can be filled via the Molding Window.
    Fill time Enter the time it will take to fill the mold.
    Note: This field can be filled via the Molding Window.
    Sink marks

    Enable this option to run a sink marks analysis.

  3. Click Run.
    The run status is displayed.

    Note: A Quick analysis calculates shell results only. For results that include an analysis of the interior volume of the molded part, you must run an advanced analysis.

Quick Result Types

Quick analysis results include flow and sink mark data, and measure only the shell mesh. For results that include the interior of the part, run an advanced analysis.

Flow Results

Option Description
Fill Time Review the time it takes the material to reach different areas within the part. The filling results can help you determine the best way to fill the part and detect patterns that indicate the potential for incomplete filling, unbalanced flow, weld lines and air pockets.

Confidence of Fill Review areas of the part cavity that may not be completely filled with material. Green areas are safe. Yellow and orange areas are increasingly risky. Red areas will not be filled under the current settings.

Note: Available in only in a quick analysis.
Front Temperature Review the temperature at the time of filling.

Pressure Drop Review the pressure required for the material to reach different regions of the part cavity during filling. Pressure Drop is usually greater farther from the inlets.

Note: Available in only in a quick analysis.
Weld Lines Locate regions during filling where two flow fronts meet. Such regions may cause structural and cosmetic issues.

Gate ID Review the material that flows from each gate in a distinct color.

Note: Available in only in a quick analysis.
Gate Contribution % Review the percentage of material that enters the mold from each gate.

Note: Available in only in a quick analysis.
Thickness Review the thickness of different areas of the part. Local part thickness affects local strain rates and heat flow. Abrupt changes in thickness cause uneven cooling, which can lead to part shrinkage and defects such as sink marks in the final part. This result can give insight into the entire process.

Flow Length Ratio Review the ratio between a region's distance from the ingate to the average part thickness. Greater flow length ratio means greater pressure is required to fill that region of the part cavity.

Note: Available in only in a quick analysis.
Quality of Fill View areas where material degradation and surface defects may occur. To improve quality of fill, you can use a larger gate size to increase flow rate, increase melt temperature to reduce viscosity, increase part thickness to reduce shear heating, use a less viscous material, or increase injection time to reduce the shear rate of the melt.
Note: Available in only in a quick analysis.
Shear Stress Review areas of high shear stress in the model. High shear stress can lead to cracks in the finished part.
Note: Available in only in a quick analysis.
Shear Rate Review the shear rate of the material in the model. High shear rate can lead to a brittle finished part with poor surface finish.
Note: Available in only in a quick analysis.

Sink Mark Results

Option Description
Sink Mark Index Detect surface depressions, usually in the thicker sections of the model, caused by shrinkage during the packing stage.

Thickness Review the thickness of different areas of the part. Local part thickness affects local strain rates and heat flow. Abrupt changes in thickness cause uneven cooling, which can lead to part shrinkage and defects such as sink marks in the final part. This result can give insight into the entire process.
