How To Make a Silicone Block Mold of an Irregularly Shaped Model: Mold Max™ 30

You can save material and money by making your silicone mold conform to the shape of your model. In this video, Milo shows how to use aluminum flashing to create a custom mold box for an irregularly shaped model.
#silicone #moldmaking #tutorial
The model is created by carving modeling board using a CNC router. Epsilon™ epoxy coating is used to give some areas of the model a shiny finish. A mold box which curves to follow the contours of the model is made using aluminum flashing and wooden buttresses.
Mold Max™ 30 tin cured silicone is mixed and poured over the model. After the rubber cures and the model is demolded, Featherlite™ resin is poured into the mold. The Featherlite™ resin is lightweight and easy to paint.

I love this kind of stuff, now you got me hooked on another skill to learn.

[@smoothon]

Let us know if you have any questions. Thanks for watching!

[@lesliemaloff7693]

I learned so much from this video. Using talcum powder to give the casting some tooth is highly valuable to me. A great teaching video. Thank you.

[@smoothon]

Thank you for watching!

[@general5104]

Hi. And talc powder, when put in a cloth bag and shake it all sround on your master pattern piece, to act as a Release

[@warkong8734]

Great video but I'm a beginner and not at that level yet. Thanks for the video

[@smoothon]

Thanks for watching!

[@KurtisJoseph]

I am getting ready to cast my Batman cowl after building a Mold from Mold Max. I am tinting with UVO Black. Will the finish be glossy? If I dust the inside of the mold with baby powder will it make the finish more matte? I need a matte black.

[@smoothon]

Hi there! It will depend on the surface finish of the piece you made the mold from. That surface finish will transfer to the mold. This is a good question for our tech support team, can you send them a ticket here? www.smooth-on.com/support/ticket/add/agree/ Thanks for watching!

[@KurtisJoseph]

@@smoothon sure will! Thanks! Yeah I painted the original and it is more glossy black. No issue if it is stuck that way. Just experience under my belt. It is not like I will not be molding and casting tons more stuff.

[@cyrus2641]

Hi, good video. Im just getting started in casting as a hobby. I started using the smooth-on 300. The masters are a two part model that snap on and off of each other, created from a 3D printer, so even thin lines and walls are quite strong. Total weight is about 2oz. I was able to cast the items great, but the problem is that they are rather fragile. When snapping them on and off of each other, they tend to snap and break. Im taking care to make sure im mixing thoroughly, the 1A:1B mix ratio is exact, and that im giving it enough cure time. Can you give some advice?

[@chuckgurley4048]

Trying to find releasing agent you used

[@smoothon]

Hello, no release agent was used in this project. If you have further questions about a project you are working on you can send our tech support team, a ticket and they can help you with your project. www.smooth-on.com/support/ticket/add/agree/ Thanks for watching!

[@nathanwhiting9010]

Very cool, great work! I am interested to know what the model of the CNC used in this video is?

[@gustavotobon7042]

Hello, love this video. The question is aside from aluminum flashing, what else can I use for the mold housing. Thank you.

[@smoothon]

Any flexible non-porous material would be suitable.

[@us3rnam3144]

how durable is feather lite? can it take a hit or be dropped without any issue?

[@smoothon]

As it is a filled resin, it is not as impact resistant as some unfilled resins, but it strikes an excellent balance between lightweight and durability.

[@jevries]

I would love to see a video where you make a two part mold using Mold Max XLSII. I tried it over and over again using Ease Release™ 200 using all kinds of different methods but it simply does not cure on keys and other recessed areas. It seems impossible to work with and I can't find good info on how to pull it off. I'm using Mold Max 30 for over 15 years now and I never ever had any problems with it.

[@smoothon]

Hi there! This is a good question for our tech support team, can you send them a ticket here? www.smooth-on.com/support/ticket/add/agree/ Thanks for watching!

[@kronosaurelius]

What is the difference between dragon-skin and eco-flex ? Are there more verbose articles or videos that explain all the silion options from smooth-on ?

[@JensLife]

How much is the stuff you used to fill the mold with? The chunky stuff? I trued the link but no prices were listed.

[@smoothon]

You can find pricing here: shop.smooth-on.com/feather-lite

[@gustavotobon7042]

Hello, Love this video and have a question. Where can I buy those wood pieces used to hold the aluminum sheet and what is the name. Thank you

[@smoothon]

They are pieces of a 2x4 cut on a table saw.

[@gladiatormechs5574]

is it possible to make a silicone mold of a dinosaur head with its jaws open and lots of teeth in its mouth.. can this work on the open mouth with teeth , or is that to difficult to make a mold of. ?

[@trashleymessbrough9483]

Would you say this smooth on max product is the glossyist/shinnist finish you have for your silicone molds? (Im looking to start making my own molds for resin but I was a super glossy mold so my resin pieces are also very glossy)

[@smoothon]

The mold rubber will reflect the surface of the original model. If you have a glossy original, the mold made from it will also have a glossy surfce.

[@MizzBellaKitty]

Would this silicone work to make a squishy nose for a dog mask? Like, the actual nose will be silicone, not the mold.

[@smoothon]

We would recommend looking at one of our Skin Safe Platinum Silicones such as Dragon Skin - www.smooth-on.com/product-line/dragon-skin/ Thank you for watching!

[@SansAziza]

Do you have any documentation on how sound affects your products? I'm interested in crafting bases and for studio speakers.

[@smoothon]

Hello, we do not have specific data regarding how sound affects our materials, but we do have several customers using our resins to create enclosures, etc.

[@kallabos7538]

Does it matter if you use talc baby powder or corn starch baby powder? After the lawsuit, talcum powder is getting hard to find.

[@smoothon]

Corn starch baby powder would be suitable as long as it is dry.

Why do you guys make it so difficult to buy your products, I've been trying to buy crystal clear and cant get it from your website, or your amazon store... only through third party art stores! What the hell! I only live 20 min from Macungie why would I buy the product from an art store 2 hours away, its dumb!

[@smoothon]

You can order Crystal Clear directly from us or Reynolds - Allentown. We require that you call us at 1-800-762-0744 or Reynolds at 844-294-1444. This is due to the fact that Crystal Clear resin should only be used in a shop or other properly outfitted facility by an experienced resin caster. Also, we are open Monday through Friday, 8:30 AM until 5:30 PM. Feel free to stop by! 😀 Thanks for watching our videos!

[@beachboardfan9544]

What do you consider properly outfitted and experienced?
