1. Are you performing 1st as injection molding and 2nd shot in reaction injection molding. then you can't

2. If both the shots injection molded. Get a UDB file for 2nd shot material for Liquid Silicone Rubber (LSR) .

Then perform as 2k molding simulation.

3. Perform the 1st has injection mold as a separate study as injection molding case & 2nd shot as insert molded with 1st shot part as a another study as reaction injection molding case

Refer this link for to simulate LSR part, consider first part as insert

now you can

Injection-compression overmolding is extended in 2018 to support injection molding for the first shot and injection-compression molding for the second, overmolding shot. & Using existing injection-compression overmolding analysis, you can simulate 2-shot overmolding where the first shot is injection-compression molding and the second shot is injection molding. This feature has been enhanced to support the reverse; injection molding for the first shot and injection-compression molding for the second, overmolding shot.
