3 minute video of what happens when you use 2 part rotocasting plastic. This is not a tutorial, just an explanation of what goes on here.

that was really cool, and intresting

nice AR cast btw

Holy Crap, all I need to do is make a mold now, question though, will it be that flimsy always? it seems rubbery.

you're my hero adam :mrgreen:

Hey Adam,

You might want to pick up some 1 gallon, 2.5 gallon, and/or 5 gallon buckets.

That way you can get enough in a single pour so you won't have differences between the two mixtures AND you don't lose any with slop from a large enough bucket. Although with each bucket the time to stir properly increases, so you'd need either a different mechanism or you'd have to make sure you can get it all mixed up within the material's pot life.

when it cools, it's hard as a rock.

Great vid Adam... I truly appreciate this.

I haven't done any slushcasting of my armor or weapons, but I have for other projects and with other materials. It makes me want to give it a shot again.

Ever thought about doing a two part cavity mold.. That you can just inject the plastic or press cast. Much easier and you'll get cleaner results.

 

[Ironcobra3000]

When you mean by cooling, does the plastic get hot when mixed?

 

[FinAeros]

The epoxy reaction is an exothermic reaction, so it produces a bit of heat.

Too much epoxy = too hot of a casting = melted mold or fire.

 

[drgon47]

its a chemical reaction that produces heat as a byproduct, so yes, it gets hot for awhile then cools.

I have a few questions...

How would a silicon mold that big cost?

Where can I get one?

What are you mixing to make the cast, and where do I get it?

 

[Sean Bradley]

I can answer these...

1. $100 - $200 dependnig on material choices

2. You have to make it yourself, or hire a moldmaker to do it for you.

3. It's rotocasting urethane... Adam said that in his first post. It's available though Smooth-On... a mold supply company.
