Sometimes you'll have a project that requires multiple parts, so rather than make each one by hand, join me while I show you how to make a basic tin-cure silicone mold and then make the cast plastic parts look like brushed aluminum with a bit of aluminum powder and steel wool!

Watched all this vid thinking you were gonna pour actual aluminum to this

@VanOaksProps Год назад

Sorry. If you're looking for aluminum casting the biggest tell is that the mold material is typically red in color. Anything else will likely not be casting with molten aluminum.

@ferretface8782 Год назад

Are you saying there is a mix and pour red mold material that can handle the temperature of molten aluminum? And can the mold be used multiple pours?

@VanOaksProps Год назад

@@ferretface8782 no, it’s a red clay and is a one use mold. If you need to make multiples you’d be looking at injection molding into steel or iron.

@ferretface8782 Год назад

@@VanOaksProps Thanks for the quick response. My design can't be produced by CNC. I'm looking right now at a 2 part graphite adhesive, but the viscosity might be a bit high for detail. I'll keep looking.

I was here hoping that aluminum molding in silicone might be possible. But nope... That's a pity

Another great video Derek. I have yet to venture into casting, but this has me intrigued to try!

@Bravo-ry9st 9 месяцев назад

Thanks for explaining the bubble removal process. Not sure why others don't explain this part in videos in more detail.

@NickWalters571 2 года назад

Great overview Derek! Aluminum powder is a good idea because it won't rust or patina like a lot of the other metal powders could without a sealer. But that effect can also be used as a design aspect for a natural weathered look so perhaps that would be a neat video for another time?

@DoktorHalloween 2 года назад

An additional tip. Smearing a thin layer of PVA (white) glue on the bottom of the mold to hold your pieces can ensure the silicone doesn't creep underneath the piece when making the mold. Keep the layer of glue thin. Afterward, water will soften the glue for removal. Also, a bean-and-cheese-free silicone is much less gassy.

Thanks! It’s a part for one of the items I sell on Etsy. I use a lot of them and making a silicone mold will save me tons of time.

@Peter_Herrman 2 года назад

@@VanOaksProps I can't believe how much air sucked out of that with the vacuum! I wonder if there's air just entrained in the liquids (I can't remember what they are)? Seems hard to believe you'd get that much air just by pouring the stuff in.

@VanOaksProps 2 года назад

@@Peter_Herrman it’s a combination of things. You introduce air into the individual parts of the silicone prior to pouring them into equal parts, then again when you mix them together. So there’s a lot of air getting trapped just in the mixing process.

@Shadoweclipse1386 Год назад

This is such an amazing video! Thanls for posting it! I'm planning on using a similar technique for a prop that I'm currently building, and I was wondering what aluminum powder you recommend? We kinda see it here in this video, but there's no product link in the description.

@VanOaksProps Год назад

My pleasure. Any 30 micron aluminum powder or finer should work. The kind I purchased is no longer available to link to. Just make sure it’s not aluminum oxide, since that’s not the same thing.

can you use the aluminum powder with the regular Smooth-Cast 300 silicone?

@VanOaksProps Год назад

Yes, as far as I know.

@MossManK Год назад

Thanks for the video! I was wondering if impregnating the resin with metal powder like you did creates any metal like feel to the resin parts at all? I'm trying to find any solution to having a "metal feel" to my props without having to resort to actual metal casting with a foundry.

@VanOaksProps Год назад

Not really. It’s the weight that gives it away.

@MossManK Год назад

@@VanOaksProps Interesting. The parts that I would be casting are for a prop blaster that already has substantial weight on it's own. I would only want the trigger to have a metal feel. Maybe it'll work. Thanks again!

@leeainscough1973 7 месяцев назад

Does the aluminium make the part surface stronger. Noticed the buffing part and wondered? You have given me some idea for metal casting and making the wax molds. Will play with aluminium powder in the wax molds. May be a silly idea but these things are worth a try. It may improve the surface finish of metal casted parts. Thank for the learning idea.

@VanOaksProps 7 месяцев назад

Not at all. It’s just cosmetic.

Is Tin Curing Silicone a viable choice in any case or is it sometimes necessary to use the more expensive platinum curing silicone? I've heard Tin curing Silicone can't get used too often to cast copies other than platinum curing silicone but I haven't tried to cast anything yet in silicone molds.

@VanOaksProps 2 года назад

They each have their place, but tin silicones are used more often because they’re less likely to have curing issues, and they’re typically less expensive. They do have the drawback of a shorter life, but if you take care of them they’ll last.

@martinez1701a 11 месяцев назад

Can I use this method to cast aluminum? I don't know if you're familiar with Rockford fosgate amps but a lot of the older amps from the 90's had aluminum end caps to hide the wiring for a clean look. Over the years people lose them, I was thinking about making replacements for my own collection of amps.

@VanOaksProps 11 месяцев назад

No. The hot aluminum would melt the silicone rubber. There are mold making supplies for casting with molten aluminum but I’m not familiar with them.

@javierfito5077 Год назад

can you tint tin silicone with acrylic paint while mixing?

@VanOaksProps Год назад

I don't believe so. They make silicone pigments that won't mess with the silicone chemistry, though.

@@VanOaksProps It's ok, I'm not sure what I expected really. Aluminium has a melting point of over 600 degrees, it'd be difficult to obtain that at home without building some kind of makeshift forge.
