Compression Molding
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.
Modify multiple material properties using a CSV file
This example shows how to update the properties of multiple custom materials by downloading, editing, and uploading a CSV file—eliminating the need to change each material manually.

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.
  - Define the mold for a design project
    You must categorize your mold components and define their materials to allow the SimForm app solver to identify them.
  - Define the mold for a feasibility project
    You must define the material of the mold in the feasibility analysis. The SimForm app solver assumes a well-designed mold considering the effect of the mold material on part quality and cooling time estimations.
  - Define the basic mold
    You must define the size and the mold material of the basic mold. The SimForm app solver considers the effect of the mold size and material on part quality and cooling time estimations.
  - Custom Mold Material options
    The custom mold material window lets you define a new mold material in your job.
  - Define a new mold material
    Define and add custom materials for mold components in SimForm to evaluate the thermal performance of different materials and optimize your mold design.
  - Modify multiple material properties using a CSV file
    This example shows how to update the properties of multiple custom materials by downloading, editing, and uploading a CSV file—eliminating the need to change each material manually.
- 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.
- Tutorials
  These examples are designed to help you become familiar with some of the major features available in SimForm.

Modify multiple material properties using a CSV file

This example shows how to update the properties of multiple custom materials by downloading, editing, and uploading a CSV file—eliminating the need to change each material manually.

A job containing custom materials.

In the Plastic Part, Mold Group, Basic Mold, or Mold Material card, expand the Select Material list.
Select Download Materials and save the materials.csv file to your computer.
Open the CSV file in a spreadsheet editor such as Microsoft Excel.
Edit the material properties you want to update. For example, adjust the thermal conductivity or mold temperature values.
Save the edited file in CSV format.
In SimForm, from the Select Material list, select Upload Materials .

The uploaded file with material properties overwrites the original material data with your updated values.
