Moldmaking Tutorial: Seamless Skull Mold With 5110 Silicone

[@h7opolo]

another SUPERB tutorial. you're the best in the biz.

[@brickintheyard]

Thank you!

Para não rasgar o melhor seria usar borracha látex, ou o silicone é melhor?

[@brickintheyard]

Latex is great for concrete casting but not for resin and foam. 5110 is ideal for casting polyurethane resins and expanding foams.

@@brickintheyard Muito obrigado pela dica, gratidão.

What would you recommend for casting a deer skull w antlers?

[@brickintheyard]

@@johndenver5029 I would use a firmer silicone like TC-5130F thickened with SC-5001

[@johndenver5029]

@brickintheyard thanks for the fast response. I'm completely new to this and trying to absorb what I can. If I was looking to make a 1 time cast to turn said antlers into aluminum what process would you use? Or would you do the process demonstrated here w the change to firmer silicone and hardener?

This was a great video

[@brickintheyard]

Thanks!

[@hardiehardley]

With your store now defunct, where would you recommend we go for our silicone needs?

[@brickintheyard]

BJB Enterprises has all the silicone you see in my videos, and they have excellent tech support. Check the updated links in recent videos (including this one.) You can also go to Fox and Superfine in Georgia. Both will have the TC-5110F from this video.

[@scotthalt4040]

How much 5110 should i get to make a similar mold to do what you did in this video?

[@brickintheyard]

@@scotthalt4040 this took about 2lbs. I think the smallest kit BJB offers is a 4lb kit so that would be more than enough.

[@scotthalt4040]

thanks! I've seen some places have 2 lb kits and you can get 3 of them for the price of 1 4lb kit also.

[@brickintheyard]

@@scotthalt4040 I think Fox and Superfine have 2lb kits.

[@scotthalt4040]

Definitely daw 2lb kits on Fox. My intent is to try and make some skulls with a 90* piece/ mount coming out of the base to mount to a wall for motorcycle helmets. Any suggestions for material? I was thinking pourable resin, maybe?

[@brickintheyard]

@@scotthalt4040 TC-808 is good for solid and rotational casting and works well for automotive applications.

[@HesCrafty]

Great video! Would I be able to pour flexible prop foam in a 5110 silicone mold?

[@brickintheyard]

Yes, but the firmer silicones, like 5130 or 5140 are better suited for self-skinning flexible foam.

[@HesCrafty]

@@brickintheyard Awesome! Thank you for the reply. Can I still make a mold out of the 5130 silicone? Thanks again. And thank you for all the awesome content.

[@brickintheyard]

@@HesCrafty yes. Just be sure to account for the expansion force of the foam.

[@HesCrafty]

@@brickintheyard Thank you so much again. Very appreciated 🙏🏼

[@jacklambert4958]

Is the 5110 better to use for than your platsil 10 silicone?

[@brickintheyard]

Not so much as better as different. 5110 is a slower setting, lower viscosity formula so there is more working time and it is much easier to use for poured molds, also less expensive.

[@jacklambert4958]

I do like the idea of a longer working time. Thank you

[@brianbassett4379]

How can I pour concrete skulls in this manner?

[@FuzzyBunnyofInle]

I'm so happy I'm not the only person researching this,..for totally normal person, normal reasons.

[@brickintheyard]

You could use this for concrete casting. But you might want to make a slightly thicker mold with a resin mother mold using TC-5130.

[@CherylBrune-tg1lo]

What is the original skull u started with made of?

[@brickintheyard]

ArtKast Polyurethane resin.

[@therealzuxana]

Gorilla brand hot glue doesn’t cause inhibition.

Thanks!
