Doll Molds {WIP} by DonnKinney Doll Molds {WIP} by DonnKinney

Just look at them in their bubble gum pink splendor. :-)

A full set of Silicone molds for an 18/17 inch doll, I just finished these for a client and I will be doing his casting work as well.  Aside from the casting/molding work for my own dolls i also do the molds/casts for a few other artists.

I was hoping to have these finisehd a few weeks back but the insanely cold weather slowed the work down considerably. Silicone doesn’t take well to cold and it sloooows down the mold making process to a crawl.

aside from a little cleaning these are finally done! :-)

Hi! This is awesome! :D (Big Grin) 

I would like to know, is it possible to buy molds from you?  How much would it be ?

Just creepin' this post again. Staring in terror as I get ready to do my first full production molds. Analyzing your techniques. ;) Aaaand... chickening out and starting a junk cast of my boy's head first. Only I'm pressure casting for the first time. I think you said before that you vaccuum cast? If so, do you think the way you do the sprue and vents would work the same for pressure casting? Fear is clouding my physics knowledge now! :)

 Don't worry you can do it :-) and if it doesn't work out you'll have learned something, the important part is to keep at it (remember ive been working with resin and silicone since 88/89 so Ive had a loooooooot of time to trial and error) 99.9% of any info out there is geared toward casting something thats a prototype or a model kit that's going to be painted, casting slightly translucent resin parts with a nice matte bubble free finish is something i had to figure out by screwing up 1000 times, haha. ;D

 I actually pressure cast, its the ONLY way to get perfect casts.. I do however de-gass my mixed silicone in a vacuum chamber before i pour my molds because if there are any trapped bubbles/air pockets in your silicone molds when you pressure cast them the trapped bubbles will collapse and deform your mold.. your finished part will look like it has the hives :-( if you used one of those super low viscosity silicones this might not be a problem though, its something i always do as a rule :-) And yes sprues will totally work pressure casting, all my tiny slim parts like arms and legs i cast with one main sprue breaking off into many tiny ones to fill and vent the parts properly but regardless,.. YOU CAN DO IT! :D

Then I'll go forth trying not to give my dolls the hives! :D Thanks so much for your help. I'll let you know how it goes. ;)

That is so very cool!!! How long do they last? one time use or many? I am not good at these types of things XD

Mold max 30 Silicone molds usually last (in good shape and using the methods i use to get super matte casts) for about 35-45casts (they begin to degrade around 35), the larger the part the more heat generated and the faster the mold degrades so for smaller molds you can often get more casts before the mold degrades.

How much silicone was required to do all of these pieces?

you are looking at just a little under 2 gallons,.. probably something like a gallon and 3/4

Interesting, it is very exciting to see this part of the process! I want to try casting some resin from home-made silicone molds sometime so it is fascinating to see your process. :thumbsup: I assume all of the bibbly bobbles are to hold the two sections together... but how on earth do you create that aspect of the mold?

Ohh forgot to tell you how i make keys, I usually make indentations in my clay dividing wall before i do my first half silicone pour, sometimes ill use plastic hemispheres seated on the clay wall itself for larger keys :D

Ooooh, very clever stuff! Thank you for telling me. :D I wouldn't have minded if you'd wanted to keep it a trade secret!

The thought of doing jointed dolls like yours is quite intimidating. My plan is to incorporate cast resin pieces into plush toys when I get round to trying it. :D

That sounds really cool :-) wayyy back in the day i did a lot of puppet/creature work and id often cast noses/eyes/feet to add to my sewn work, usually I only needed to make one part (open back) molds, they are a lot easier (and more fun) to make than keyed 2 part molds :-)

Glad you enjoy the pic :-) yea all the little knobs are called keys, they keep the soft parts of the mold aligned and perfectly registered.. Ive been making silicone molds since 1989 so Ive done a LOT of experiments/trial and error to figure out what works best for the way I cast :D

I'm familiar with the trial and error process, though for me it usually applies to sewing! I used to be extremely reluctant to 'sample', and now I could do it all day. :lol:
