Instant Mould

[Casual Heresy]

So I've recently acquired some instant mould for a project i'm working on. I need to replicate a large amount of forgeworld brass etched pieces for squad, company and chapter insignia.

 

Now I know that Instant Mould is designed so that Green stuff will not stick to it. My question for those of you who have used it is does it still do this after curing.

 

i.e. If I was to make a press mould, use and leave the green stuff in until it cures, would the Green stuff still come away cleanly or would it adhere to the mould as it cured?

 

Thanks for any help or insight you can provide.

It should still come away cleanly.  the only problem I've had with it is making my moulds too thin at their deepest point.  I suggest half again as much as you think you need per push mould.

I've left GS in IM for a week or so after curing and had no issues with getting it out. :)

Only one way to find out ;)

I usually let the green stuff cure in the mold so I don't accidentally deform the piece.

 

The problem I forsee is that the FW etched brass is crazy thin.  If you can manage to pull a mold for it, you are likely going to have to overfill by a lot and trim it down.

Glue the bit you want to clone on a smal pies of plasticard, I´d sugest, so the  proces will be easier.

Let it drt at least 12 hours is how I did mine on the shoulder pads

Alltough it ´d be a lot easier to put them on the pads if they´re still flexible.. but you have to be really careful not to destroy the cast...in my opinion the easiest way to make shoulderpads would be to actualy glue one brass piece to a shoulderpad how u like it, and then make a mold with Instamold ( thats how I do it for my "veterans" and Specialists squads).

Instant Mold is a rebranding of a japanese product called Oyumaru and it is not necessarily designed just for GS.  You can use it with 2 part liquid resin even.  For tiny stuff, you can use single part putties such as Vallejo plastic putty/Stone Liner, or tamiya putties, provided they are not going to be flexed.  You can experiment with them, but please be mindful of the stuff you cast, especially here...;)
