Description
Just a quick tutorial on making molds for dolls!Also a note: If you use anything other than Oomoo(shown) or Mold Max silicons from Smoothon.com, please be careful of using legos for molds. The Oomoo and Mold Max silicon is thick enough that it doesn't bleed through the sides, but other thinner silicons(like dragon skin) will. So be aware and test a small portion first if you're concerned.
While this is shown using Oomoo molds, I use Mold Max 30 for most of my mold making.
However, I do recommend using Oomoo Silicon if it's your first time making molds. It's cheaper and measured by 1:1 volume so you don't need to buy a scale for weighing your components. Just know that your mold will only last about 10 casts or 1 year before it starts to warp and tear.
If you want a tutorial on how to make a simple mold and work with silicon in general, check out Dan Perez Studios:

he's got some great tutorials!

Thanks! I was starting to wonder how to cast the torso.

Also I see that there is pourable oomoo and brush on. I'm assuming you use the pourable, but is it possible to use the brush on kind?

you can use the brush on kind if you want, but you'd have to use a mother mold of plaster or brush on resin in order to use it. It's a messy process, and kind of frustrating to do. It can potentially save you a little money, but probably not as much as you think.

Awesome thanks for the feedback! Yeah the whole money things a problem for me so I decided I better not try to make one just yet. Gotta be patient. I don't trust myself enough not to fuck up yet. I'll probably stick with clay until I'm ready.

I have some questions some people have already asked. You said to check out the link to Dan Perez studios. But that link doesn't work for me.

Pop it into the [link] to access it. He took his site down.

How does the inside mold work? I get that you put the two pieces of the mold together, pour in the resin... and do you just set the core of the mold inside it? How does it not float around or push out your resin? Sorry this is so hard to grasp for some reason.

The inside is balanced inside the mold. I put keys on the plug so that when the inner part is cast it will fit snugly into the front and back of the mold. the keys keep it from moving during casting.

Thank you! And the tutorials are really helping me understand this.

nah it's fine, i'm just not good at explaining. :3

Oh, thanks. And you're good at explaining. I've understood a lot of what you've said in tutorials. And the videos with afternotes make perfect sense. Do you really only get 10 molds out of each casting silicone, or do you use a stronger one? And do you only sell dolls you can proffessionally cast? And one more... which type of resin did you use from Polytek? I'm trying to figure out which one of their fancy wordings is polyerthane resin for pouring. Thank you sooo much! I will cite you on my web site if thats okay with you.

thank you so much for the link to your tutorial!! (i am the girl from youtube, kiddo!
another question: how do I cast my resin doll in this mold? because there have to be a hole for the strings and i am not really sure how to do this with the mold.....
could you help me?

You have to put a gate on it, which is the pour spout that the resin can go into. Take a look at the Dan Perez site that's linking in the comments above. He explains better how to set up molds.
For making the stringing channels you can use straws that have been closed up with glue or plastic cylinders that you can get at places like TAP plastic.

thank you so much for your reply! I think after my exames I will try do make an own doll. But it sounds very difficult. I am very impressed by all the people who have ever made a doll.

So, when you actually cast, do you put the straws in again or what? Sorry, molding for dolls is hard to understand, which is bad, because that's my independant study project this winter XD
👍: 0 ⏩: 1
yup! I plug the straws with hot glue and then put them back in. makes for hollow cores! and the plastic straw is easy to pull out of the cast afterward. You can alternatively use acrylic rods, but those are more expensive and harder to pull out unless you grease them with mold release every time(petroleum jelly works well for stuff like that)

it was made with the expectation that you already know how to build a simple mold. [link] Dan Perez has really good explanations on how to build molds.

you're like the MacGuyver of doll making. Impressive!

Cool! That's better than more expensive materials or having to have a whole foundry set up to do ^__^

haha~ thanks. XD I'm just born from a bunch of mad scientist types! my family is very much about kludging things together.

[link] it's from "There I fixed it". a lot of things around the house were fixed in the same sort of haphazard questionable way when i was a kid. I take after that. XD

So do you drill out the neck hole? What was the point of the straw again? Pour hole? Sorry if these are silly questions. Could this have been 4 piece mold and had the neck hole area be the fourth? Thanks for posting this!
👍: 0 ⏩: 1
yeah, that's what the straw is for. You plug both ends with hot glue and set in there. Alternatively you can get acrylic rods that are the same diameter as the straws. They're reusable and if you grease them with a little vaseline they come out real easy. Because my original parts aren't always hollow and straight I use straws since they have give to them. You could make a fourth mold part and make the neck hollow with silicon- but the thinner you get silicon the more likely it is to tear. You'd want to use something super firm like Mold Max 40 and make sure there was a key in the lower mold that the neck part fit into so that it hangs straight.

i like using cardboard now for larger molds, but i like using the legos for anything small. it's so much faster than measuring and cutting!

Thanks for posting a mold-making tutorial! My brother's been interested in casting, I'll point him in this direction.
