Compression Molding
- Compression molding overview
  Use SimForm to perform a thermal cooling analysis for your plastic compression mold designs. These analyses help you identify hot spots on the plastic part and develop cooling layouts to improve the part quality and reduce cycle times.
- Setting up a simulation workflow
  You can set up and run a SimForm project by uploading your CAD file, categorizing components, selecting materials, and running simulations.
- Navigating the app interface
  The SimForm interface allows you to create and access projects and jobs, as well as add and manage users and account credits.
- Using projects and jobs
  Use projects and jobs in SimForm to manage and organize your mold design tests.
- Setting up a simulation
  Use the setup page to categorize and define your model components properties for the solver to identify them.
- Defining mold properties
  Defining mold properties based on your analysis type ensures that the SimForm solver correctly identifies the mold components in your CAD model and considers their material properties in the thermal analysis.
- Defining plastic part properties
  Categorize your plastic part components and define their materials to allow the SimForm app solver to identify them.
- Defining cooling channels
  In design projects, if your model contains cooling channels, you must define the components that represent them so the solver can identify them.
- Running a simulation
  When running a simulation, the solver relies on specific assumptions and automated processes to ensure accurate and efficient results.
- Viewing results
  The results page allows you to view and explore the thermal analysis results of your job after its simulation is completed.

Display the freeze time and the temperature distribution on the plastic part and mold to locate regions where you can improve the cooling and optimize the cooling time.

Click Results to open the results page.
Rotate your model using the model manipulation tools to inspect the freeze time distribution on your plastic part.

The display window shows the global and local freeze time, or safe ejection time, distribution on your plastic part in seconds.
In the Display Mode panel, select Filter Plastic then move the slider to the target cooling time. For example, 4s.

The display window shows the areas of the plastic part where the freeze time is higher than the target cooling time. You can consider adding cooling channels or baffles in these regions to improve cooling efficiency.
Select Plastic Volume to display the volume temperature distribution of the plastic part.
Select Cutting Plane and the X axis.
Select the Invert check box to invert the cutting plane direction.
Move the slider to change the cutting plane position to identify the regions with high temperatures. For example, to the -0.032 position.
Select a region with a high temperature in your plastic part to inspect its local result.

You can use the local freeze time and temperature results to identify areas that take longer to cool down. This helps you optimize the plastic part—for example, by reducing wall thickness—and improve the cooling system design by adding highly conductive inserts or baffles. You can also use the global freeze time to accurately estimate the part cost for a quote and provide a realistic cycle time target for the mold maker. Once the mold is designed, you can compare its actual cooling performance to the feasibility analysis of a well-designed mold.
