I don't know bout anyone else, but all this talk about Silicone Bodysuits is making me wet....
David Pea your such a cock tease! Where is the tutorial???????
I know, I know...you're absolutely right. We're about to release our Batman Begins line and topped with the announcement of our LucasFilm license for introduction of those licensed goods as well, all this has seriously dug into my message board 'fun' time.
However, here's a little bit.....
Silicone is heavy. Heavier than latex and certainly heavier than foam latex. The advantage to silicone is the flexibility of it and the tear resistance of the material used. Platinum silicone is what's used for costume skins, not Tin. Tin breaks down far quicker and is not made for this kind of repeated flex and stress. For moldmaking, tin silicones are perfect, but for any costume use they will also inhibit the cure of platinum silicones so it's important not to use Tins when looking to use any kind of Platinum silicone.
Here's an example...
Legs:
You want to sculpt over top of an established body form, one preferably already set up with keys for being cored.
See the keys? That allows the rubber urethane mold, and rigid mother mold to lock into the core (pink) and the clay you see is removed...leaving the sculpted area void for the silicone to be poured into it.
This pic shows the urethane skin (I believe it was Brush On 40 by Smooth On) being removed from the secondary sculpt. Platinum silicones will naturally release from certain urethanes and we've done a lot of brush up molds with this technique.
This shows the rubber mold now wrapped onto the inner core, and there now is a complete void where the clay used to be...
Placed into the bottom outer mold, mother mold. This holds the rubber urethane skin mold in place and anchors it in so there's no shifting.
Here you can see the pour holes/air venting holes.
With the front mother mold bolted to the back and to the inner core....again, we dont want any of the mold sections to shift...
At this point, the mold is secured and ready to start pouring the silicone....
See the smaller screws on the inside of the core? Those are bolted to the mother mold...nothing is going to move or shift.
Now you can start pouring. Get up as high as you can...let the silicone pour out in a thin stream. This will also force most of the air bubbles to pop on the way down, reducing the risk of trapped air bubbles. Even if you degas your silicone it is very important to pour it this way considering how big the cast piece is and the amount of silicone you're working with.
It's hard to show in these pics, but there are bleeder holes scattered all throughout the mold allowing the silicone to bleed out, forcing out any trapped air as well. As the silicone bleeds out of these tiny holes, they're pluggged with clay.
The two large openings serve for pouring, only into one of the larger openings...and the second opening is for air release as the silicone rises and fills the mold.
All topped up!
See the clay pressed into the core? Those are just some of the bleeder holes plugged up.
Typically, closing and bolting the mold is what takes the most time. Otherwise, pouring it up takes about 20 min tops. Then you walk away and work on anything else while waiting. You can run dozens of molds this way on a daily basis.
The next day, the silicone is set so the mold is opened...
Trimmed while still on the core....
The blue silicone was tinted that way because these legs were promo suits done for the Toronto Maple Leafs...it's been a few years now.
Prior to that, black silicone was used as well...naturally.
Silicone cast pieces really do flex well, but need to have a proper padded under suit or muscle suit to sit on otherwise they'll cave in.
I know I skipped some things here and there, and need to get into inhibition much more....the kind of clay you can use for platinum silicone molds and so on...but consider this Part 1.
For now.
Painting silicone, now that's also really cool!!!!...and more on the painting later.
Here's some silicone suits, painted and in some cases finished...
Silicone Wig...it's what the Maple Leafs wanted..(we also made the leather Vader and Elvis suits)
Here's those blue legs, and the rest of the suit...the guy wearing it was part of the TML hockey team staff, and a little skinny for the suit.
If you guys have questions based on anything above, just ask....I'll be happy to answer everything but please continue to be patient as we're really in the thick of things with our new products.
There's more to all of this then listed above, and please understand that I'm in no way saying silicone is best....or better than any other material. It worked great for us at the time when we were doing promo suits....flexible, paintable...you can glue it....and the list of personal advantages goes on and on. The reality is it does have it's down side as well...but have a look, give this stuff some thought and fire away!!!!
Thanks, and enjoy. More to come later.
