Setup and review the compression molding process settings

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.

1. Ensure the study from the previous task is open.

2. Click (Home tab > Molding Process Setup panel > Select Material) to open the Select Material dialog.

3. Click the Manufacturer drop-down list.

4. Scroll through the list until you find Rogers.

5. In the Trade name drop-down list select the material RX630.

6. In the Select Material dialog, click OK.

7. Click (Home tab > Molding Process Setup panel > Process Settings). And enter the following parameters:

   • Page 1:

     • Mold surface temperature: 177 ºC.
     • Melt temperature: 107 ºC.

   • Page 2: (Settings unique to thermoset materials, this page is not present in the process of thermoplastics)

     • Melt initial conversion: 0.
     • Curing time: 60 s.
     • %Air mass: 0 %.
     • Preconditioning analysis: Perform preconditioning analysis.

   • Page 3:

     • Compression direction: -Z.
     • Pure compression press open distance option: Automatic.
     • Press compression time: 10 s.
     • Press speed cap: 1000 mm/s.
     • Press compression force cap: 150 tonne.
     • Distance, row 1: 0.1 mm /Press compression speed 5 mm/s.
     • Distance, row 2: 10 mm /Press compression speed 5 mm/s. The Press compression speed vs distance (compression is along z-axis) allows you to set the incremental distances for which the compression press moves. In each increment, the press moves at a constant speed. For each increment, enter the distance and speed.
     • Switch to press force control: by % nodes filled at 99 %.
     • Compression force after switch to press force control: Relative to the value at switch over.

8. Select Finish.
