Injection Molding
- Injection molding overview
  Use SimForm to perform a thermal cooling analysis for your plastic injection 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.

Define the mold

Categorize your mold components to allow the solver to identify them. You will then define their materials.

You will categorize the mold components into two mold groups, one for the mold cavity and one for the mold core. This allows you to view the results of each mold group separately.

In the display window, select the mold cavity.
In the Mold Group 1 card, click add to assign the cavity as a part of mold group 1.
Click expand to view the list of added components for verification. If necessary, you can click remove to remove a categorized component from the mold group.
In the Mold Group 1 card, click hide to hide the categorized component to verify that your components are correctly categorized.
Repeat steps 2 and 3 to select the sprue bushing and add it as a part of Mold Group 1.
In the display window, select the mold core.
Click Mold Group to create an additional mold group.
In the Mold Group 2 card, click add to assign the core as a part of the mold group 2.
Click hide to hide the categorized component.
Repeat steps 6 and 7 to select the ejector pins and add them as a part of the Mold Group 2.

You must categorize all components in contact with the plastic part into one of the mold groups to ensure accurate temperature results. Excluding them from the analysis creates additional sources of cooling that distorts the temperature results and the cooling time estimation.
In each Mold Group card, expand the Select Material list and select P20 Mold Steel to define the mold material.
