Type of Mold for silicone casts

[Talion]

Random question....usually I would use a silicon mold to make a white metal cast.

What type of mold would I need to make a rubber or silicon cast?

Reason - I want to make a mold of the deadzone scenery clips, and cast them in rubber or silicone to make them more flexible.

Not sure if this will work for your application, but check out Smooth-On's products.

They have some flexible materials:

Depends on what type of material you are using to cast. For urethane rubbers, silicone molds should be fine. For silicone casting material, molds out of non-silicone rubber, metal, plaster, should work.
