Hi,
I am hoping to make a small run of electrical products that need to be cast in black resin.
In order to do this I will first need to make a silicone mould of ‘part a’.
Once I’ve made the mould I want to cast a silicone copy of ‘part a’.
Finally I would like to use the silicone copy of ‘part a’ to make another mould which I will then use to cast my final part in resin.
My question is, how do I make a mould for casting silicone as I assume wet silicone will bond to dry silicone? If this is the case does that mean that I can add to a dry piece of silicone with wet to make a more complicated mould?
Thanks, Stephen
