Compression Molding

This tutorial familiarizes you with the setup of the compression molding process and review of key results.

Tutorial duration: Approximately 45 minutes.

Autodesk Moldflow Insight is set for simulating injection molding of thermoplastics parts, by default. Most of the tasks required to simulate other processes are the same. However, the procedure to setup a compression molding process requires a few extra steps compared with the setup of an injection molded part.

In this tutorial, you will:

Tasks list

  1. Select the molding process
    In this task, you select the molding process and the analysis sequence, steps necessary to run a compression molding analysis.
  2. Assign the properties of initial charge and compression elements
    In this task you assign the properties necessary to run a compression molding analysis
  3. Setup and review process settings unique to the compression molding process
    In this task you first select the material to use for this application and then enter the process settings that are characteristic of a compression molding process.
  4. Review of the compression surface property assignment
    In this task you review the assignment of the compression surface property of the part. The correct assignment of values is critical for accurate compression molding analysis results.
  5. Review of the cavity volume: XY plot
    In this task you review cavity volume: XY plot. This plot provides you information regarding how appropriate or not were the process settings used in the analysis. You can use this information to optimize the process.
  6. Review the press force results of the compression molding process to determine the quality of the part
    In this task you review the press force results of the compression molding process. For this exercise you evaluate if the process settings are adequate to obtain the part thickness within 3% of the design thickness which is the tolerance set for this part.
  7. Review the press speed results of the compression molding process to determine the quality of the part
    In this task you review the press speed results of the compression molding process. For this exercise you evaluate if the process settings are adequate to obtain the part thickness within 3% of the design thickness which is the tolerance set for this part.
  8. Review the press displacement results of the compression molding process to determine the quality of the part
    In this task you review the press displacement results of the compression molding process. For this exercise you evaluate if the process settings are adequate to obtain the part thickness within 3% of the design thickness which is the tolerance set for this part.
