Mold Star® silicones cure to soft, strong rubbers which are tear resistant and exhibit very low long term shrinkage. Molds made with Mold Star® will last a long time in your mold library and are good for casting wax, gypsum, resins, concrete and other materials. Cured Mold Star® rubber is heat resistant up to 450°F (232°C) and is suitable for casting low-temperature melt metal alloys. Note: Mold Star® rubbers are not intended for brush-on moldmaking.

Do not remove the model from the mold.
@@voxel9470 I agree with you.

Smooth-On How much silicone was used in this? What was the box volume? I want to cast a glass sphere about that size possibly using mold star 15 or16.
Thank you! 👍💓💓
The illustration in the beginning was great.
best, clear, to the point art class ever.
Instead of using a box, use Lego which makes it easier to get the first level, then build it further up to the desired height for Stage 1 of the silicone casting.
better yet: use BlueBrixx or some other Lego-Clone. MUCH cheaper, especially when building larger boxes ^^
Hate using legos
@@tommcelroy6975 why? Works Great
Very well done! This video has helped me tremendously for making a two part mold. Thank you so much for doing this.
After researching a number of different options in silicone mold supplies and urethane casting resins, you guys win. Internet commentaries only have good things to say about your products. Very helpful videos too.
THANK YOU! I have put off making molds because couldnt get the split concept and how it work.....it's finally dawn for me.....😊♥️💛🧡💚💙💜💗
I am glad this worked out for you!
Im a ceramicist and I had seen a demo for this and resin casting at a local supply shop. Glad to see you on youtube.. Seen the Reynolds (neighboring states) catalog photo of a cast boat. That definately piqued my interest along with other cool project ideas cant wait to start working with Mold Star. I'm currently sculpting a collection of figurines. Great detail that the silicone cast captures on the orb. Have a great day cheers to the future. 🙂
Awesome! Thank you!
In general making a two-piece mold like this the seal will be fairly tight but there may be some flashing to trim. I would recommend looking at the follow-up video to this one where we actually cast into the mold. For this mold, the seam comes out quite cleanly.
Smooth-On what silicone was used in this video? Im looking to get the same grade
I did this but got air bubbles using rebound 25. Do you have any suggestion for me ?
Mold Star 15 is a good material to use to mold complex or ridged shapes because of its durability and flexibility. In terms of casting into the mold, there are a number of options including resin, gypsum, concrete, and low-melt metal alloys (up to 450°F).
never made a mold before but that idea with the nuts to make the connections is ingenius this makes me want to mold something now :D
this is one of the best silicone molding vids i've seen up here...nice work
Thanks for a great dummy proof video :D My first time making molds and I found your video to be the most helpful!
Easiest 2 part mold ive watched. Great video.
Glad it helped
Make sure the clay is non-sulphur - and if dry, is sealed with Superseal. You can cast silicone into silicone as long as it is the same type of silicone and Ease Release 200 is used.
This is the best step by step i found 👍
Excellent no fluff video straight to the point and so informative. Love it!
Thank you for watching!
Thank you! You just solved another problem for me! I am trying to work smarter not harder!
Thanks for watching! 😃
Mold Star 15 is compatible with a wide range of casting materials. You might want to check with the resin manufacture to see if there is any known issue with platinum silicone or do a small surface compatibility test. Depending on how lightweight you want the piece to be, you could consider our Smooth-Cast 325 (it's what we use in the follow-up video to this one).
Great video!! Doesn’t get more simple than you made it in the vid.. thanks for sharing
Thanks for outstanding knowledge
I'm attempting to make Power Coins for my 1993 Morpher - this video helped a lot - I just need to downscale the project for the small coin. 😃
Thank you. Very nicely explained

I Like to Paint my Source model with the silicone, right before pouring.. I believe it really helps with bubbles, especially in horizontal overhangs.. Brilliant Video xx :-)
Thanks for sharing!
We used a sulfur free clay called Sculptex available from Reynolds Advanced Materials. No de-airing is necessary with Mold Star 15.
Greetings ✋✋✋!
Wow, very helpful tutorial,
Big like, keep safe &
Keep connected!
Exactly what I needed thanks
Use Sculptex or Chavant NSP - both good Non Sulfur modeling clays.
Nice vid. Planning a zombie army build with a buddy at work. This will make short work of all the heads and hands. Thanks.
Wish everyone stay safe. I do sculpture in Vietnam 🇻🇳 😍😍😍😍
Just about anything can be used to make the mold box. We used a clear acrylic for this demonstration for visibility. But the walls could be made out of non-sulfur clay, melamine board, sealed wood, etc. You could ask your local Smooth-On distributor if they have any specific material they recommend or sell for containing walls.
You read my mind! I was just about to ask!
Those are clear acrylic sheets, but almost anything could be used to construct a box around the mold. We chose something clear so that you would be able to see the whole process.
Thanks for the subtitles, I can read English and understand but not when hear it.
I cant imagine being able to read and write in another language. That's so cool!
very nice work, good job
Thanks for watching! 😃
would love a mold making tutorial on two part molds for four legged objects like a horse. love your videos clear presentation and your product
Great idea! Thanks for watching, and don't forget to subscribe!
thanks! i thought I was subbed on this ojne, but it's on my other account! subbed here too!
great video, thanks so much
@bondophobic It is always best to run a small test to make sure the material is compatible. Damage to a painted surface may be an issue dependent on the type of paint, age of paint, etc. Our Ease Release 200 is a suitable release for silicone moldmaking in most cases. Jason - Smooth-On, Inc.
Reynolds Advanced Materials is our full-line distributor in Orlando.
Perfect video- Thanks!
Now, is there a way to reproduce the mould if you wanted to sell them?

Awesome! Thanks!
That is perfect! Thanks for sharing

This has been a great help, thank you.
You will need to have pins or similar supports attached to the core which keep it centered in the mold.
Hello! I purchased these products to make a two-part mold. I wanted to find out whether an object that needs to be seamless (like a perfect square), would come out seamless if cast from this type of mold. Thank you for any advice. Your videos are helpful.
Thank information
Our Smooth-Cast 65D is popular for your application.
You could do that as well, but the clay would have a hard tome clinging to the surface of the orb to create a seal. Smooth Cast 300 may be suitable for your application, but our 65D has a bit more impact resistance.
That is awesome! Thank you for sharing.
+Sandra Leishman thank you for watching!
Love the video. Thanks. How is the clay funnel not detaching from the model and starting to "float" once you pour the silicone?
The clay is tacky enough to stay in place.
@copburner This material can withstand about 400F. The material will not melt at higher temperatures, but will be damaged.
Love this and want to try it. Can you tell me where I can purchase the orb used for this tutorial. Thank you.
This was from a home decor store.
Grat video .Thank you very much
You could use this for wax casting. The temperature resistance is around 450F.
perfeito trabalho.
Instead of using clay; could sand be used instead? or would the smoothon seep through that?
This is a good idea, but yes, the rubber would seep through and cause problems with demold. Clay is also nice because it stays in place if adjustments need to be made.
Most polymer clays are compatible, but you should do a small scale test to determine suitability.
Very Helpful, I just bought a Starter Kit from you guys!
Sensational, nice video !
The Mold Star silicone used in this video is rated up to 450°F. Mold Max 60 is our highest temperature rated mold material, up to 560°F, which can accommodate many low-temperature melt metal alloys.
@righteoushero You can use any non-porous material. Melamine board from a home improvement/hardware store works well.
Hello could you tell me please, on how many castings from plastic lack silicone forms from mold star 16 fast?
I'm trying to make micro radio control airplanes using this process. What i want to do is take a regular plastic model plane ( like a Revell model ) Make a mold using some material that will be both light and flexible. The plane fuselage will be hollow to allow the micro size electronics to go inside. I need something like a rubberized foam. I like your video on how to make a mold using clay, that helps me alot. If you have any input in what i am trying to achieve it would be appreciated.
How would I make a 2 part mold for beads? I've watched your second video linked at the end, and this one, as well as many of your other videos, and I'm not sure how I would cast a mold for beads. I really want to make my own beads, but not sure how I could replicate them using Smooth-On products. I have the Mold Max 29NV and EpoxAcast 690.
Also, do you have a calculator for ensuring the amounts mixed are proportionally correct? I've wasted a lot of epoxAcast 690 due to calculating mistakes.
We do have such a calculator: www.smooth-on.com/support/calculators/#ratio In regards to your other question 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!
Thank you so much!!!!
No problem!
P.S. Your videos are amazing.
This video helped me tremendously. I made my first mold and I am at the first part. I let the mold cure overnight but when I went to take the clay off, the mold was still wet underneath. Is that normal?
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!
When the cast is cured after the 4 hours, does it have a smell it it ? If it does, what does it smell like and would it last forever ?
Good. Getting that clay out of all the pockets on the part must be time consuming, though 2:49 Could you have sprayed the part bottom to keep the clay from sticking ?
A good idea if you are using oil clay. with water clay a wet brush makes quick work of removing clay residue.
@BurpAtTheMoon Yes, Mold Star 15 can be used for very small models or plastic miniatures.
If the thing being modelled is disposable can one simply cast the entire thing and just cut the mold in half?
This might be possible, but you would still need to incorporate a pour spout, and without keys, mold half alignment would be very difficult.
These look great for casting BJD peices!!! What clay did you use for the base and are there other materials that can be used for that base layer? I dont really have clay like that! Also, would any no stick spray work or does it have to be demolding spray?
You can use any non-sulfur clay. You need to use a mold release, not a cooking spray. Thanks for watching!
I did some further research, and ended up sticking it in the oven at 200°F for 5 hours, which made any of the uncured rubber finally set.
so good
Thank you for watching!
wonderfully made video. Does this work for making shpaes that aren't so smooth and might have a bit of a ridge on them and what could you then fill the mold with after it is complete? Is there a better way to make multiple statues?
It would be fine if the sculpting took a long time. Just make sure Ease Release 200 is applied to the first half before the second half is poured.
Awesome! BTW I got a question. How can we make a silicone mold of something that has holes? Like for example, the lid of a salt shaker?

Thanks mate.
Wow, this looks much easier than I anticipated. Now to try it for myself...
I'm wanting to make a mold for a dice (a d20 dice) all sides have detail on them, there's not really a 'top' or 'bottom'. what would you recommend doing for placing the spout? Also, can this mold material withstand heat? Say, for heated glycerin soap?
can this be done with amazing mold? the pink silicone rubber?
This vidio was very helpfull.would you please gide me how can I bay the material in the gulf area or in KSA?
How much would it cost if I wanted to buy the supplies to do this exact project? Thank you.
It is definitely a possibility to make a 2-part mold of a Harry Potter style wand.
Cool video! Have you thought about injecting?
This might seem strange but is it possible the finished mold be used for casting the same silicone rubber mold itself? As I may want to create projects made of this silicone material as well.
Yes, as long as a release agent such as Ease Release 200 is used.
Hi! I have a mold shape similar in size to the example in this video. My problem is that the surface is very ornate and has areas that are hard to get at after doing the first half of the mold. It's a repeating pattern...so no avoiding that. I spent a day trying to dig out the clay the first time and the second time I masked the seam area with tape but ended up with an even worse scenario with the silicone leaking onto the surface. So....is there a pro way to mask ornate surfaces AND is there a way to make silicone come off a mold object easier?
+tibor warski You may want to try a film producing sealant like PVA or clear acrylic spray.
Smooth-On I'll explore those options but with the mold I had going, I removed the object from the half mold to clean it as getting the silicone out was impossible. Made makers to ensure alignment when I placed it back it. Got away with it but don't want to have to do that again. Thanks!
como se llama el materiao
I need to make a mold of a ceramic object. Will this still work? Also, I'll need to glue pieces together, is their any specific glue I'll need? Finally, do you sell harder silicone to make the casted object? Thanks.
is there a way to keep the silicon mix remaining in the mix container from curing so that you may use it for the second half?
StudioSambodia No, you should try to mix up only what you will need for each half. You can estimate how much material you will need by using our calculator: www.smooth-on.com/tools.php
Genious, thanks a lot
There are many ways to go about this, and many forums outlining the techniques. I would recommend visiting one of the mermaid tail forums for further help.
Can you tell me what kind of clay is this? Any clay will do? or is it special clay for casting purposes, can I buy it on your website?
I wish to degas my mold and cast but have no budget nor the time to make a diy vacuum chamber or pressure pot. Can I still achieve this perfect cast without having to degas? Because I'm running out of time..
The materials shown do not require degassing.
@SmoothOnInc Thank you, i have one more set of questions,
The level of importance on what is needed is:
