Setup the two-shot overmolding process

In this task you first select the materials to use, and then setup the process settings that are characteristic of a two-shot overmolding process.

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

2. Click (Home tab > Molding Process Setup panel > Select Material A), to select the material to be used for the first component.

3. Click the Manufacturer drop-down list.

4. Scroll through the list until you find SABIC Innovative Plastics US, LLC.

5. In the Trade name drop-down list, select Lexan LS1.

6. Click OK.

7. Click (Home tab > Molding Process Setup panel > Select Material B), to select the material to be used for the overmolded component.

8. Click the Manufacturer drop-down list.

9. Scroll through the list until you find Advanced Elastomer Systems.

10. In the Trade name drop-down list, select Santoprene 121-75 M100.

11. Click OK.

12. Click (Home tab > Molding Process Setup panel > Process Settings), and enter the following parameters:

    • Page 1: Fill + Pack Settings for First Component Stage

      • Mold surface temperature: 80 ºC.

      • Melt temperature: 300 ºC.

      • Filling control: Injection time of 1 s.

      • Velocity/pressure switch-over: by %volume filled at 99 %.

      • Pack/hold control: %filling pressure vs time.

        • Distance, row 1: at 0 s 80% Filling pressure.
        • Distance, row 2: at 10 s 80% Filling pressure.

      • Cooling time: Specified of 10 s.

    • Page 2: Fill + Pack Settings for Overmolding Stage

      • Mold surface temperature: 60 ºC.

      • Melt temperature: 200 ºC.

      • Filling control: Injection time of 1 s.

      • Velocity/pressure switch-over: by %volume filled at 99 %.

      • Pack/hold control: %filling pressure vs time.

        • Distance, row 1: at 0 s 80% Filling pressure.
        • Distance, row 2: at 10 s 80% Filling pressure.

      • Cooling time: Specified of 10 s.

    • Page 3: Warp Settings

      • Warpage analysis type: Small deflection
      • Use mesh aggregation
      • Number of threads for parallelization: Automatic.

13. Click Finish.

14. Click Analyze in the Study Tasks pane, to run the analysis.
