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.
Ensure the study from the previous task is open.
Click
(Home tab > Molding Process Setup panel > Select Material A), to select the material to be used for the first component.Click the Manufacturer drop-down list.
Scroll through the list until you find SABIC Innovative Plastics US, LLC.
In the Trade name drop-down list, select Lexan LS1.
Click OK.
Click
(Home tab > Molding Process Setup panel > Select Material B), to select the material to be used for the overmolded component.Click the Manufacturer drop-down list.
Scroll through the list until you find Advanced Elastomer Systems.
In the Trade name drop-down list, select Santoprene 121-75 M100.
Click OK.
Click (Home tab > Molding Process Setup panel > Process Settings), and enter the following parameters:
