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! 👍💓💓
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.
Very well done! This video has helped me tremendously for making a two part mold. Thank you so much for doing this.

@Anonpeace Any time the mold is in separate pieces or is cut, there will be a seam line. The techniques used to make the mold will determine the amount of clean up the final piece will need.
@legoclockfreak710 If you go to the Smooth-On website, click the Distributors link near the top right of page to locate a local distributor. You can also order trial sizes directly from the website if you live in the US.
best, clear, to the point art class ever.
@mokunakoi You can use Ease Release 200 in many applications, including casting resin into a silicone mold. For more info on Ease Release 200 - search for "ease release 200" on our site.
Thankyou for the tutorial!! :).
If you done with the casting for both sides, how do you glue them together?
The illustration in the beginning was great.
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.
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).
I am glad this worked out for you!
@nuebKitsune There are many different ways to make this type of mold, our how-to PDF outlines several different techniques. smooth-on(dot)com/howto(dot)php
this is one of the best silicone molding vids i've seen up here...nice work
@Horis573 Check out our channel for a lifecasting playlist that you might find useful.
@pbandjay05 There will always be a defect where the spout is, perhaps this could occur on the corner of one of the facets? If you contact use directly on our technical assistance form, it may be easier to describe the piece in detail.
Excellent no fluff video straight to the point and so informative. Love it!
Thank you for watching!
Thanks for a great dummy proof video :D My first time making molds and I found your video to be the most helpful!
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
@ecwman44 This will depend on your particular application. I would recommend calling us to discuss the details of your project so that we can help make a recommendation. Our toll-free number is 800-762-0744.
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 ?
@blckjade05 Our Sorta-Clear series is our line of semi-transparent silicons. You can obtain Ease Release 200 through our distributors listed on our website. As we do not manufacture 66B, I cannot make a recommendation for a release.
@blckjade05 We have a few materials which may suit your needs. In the essence of getting a quick response, I recommend you submit a support ticket on our customer service page.
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.
Great video!! Doesn’t get more simple than you made it in the vid.. thanks for sharing
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!
Yes, this is essentially the same process as demonstrated in this video. If you need more detailed support with this project, feel free to contact our tech support line at 800-762-0744.
@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.
THANK YOU! I have put off making molds because couldnt get the split concept and how it work.....it's finally dawn for me.....😊♥️💛🧡💚💙💜💗
Use the 'Contact Us' link on our our website to contact us directly.
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. 😃
Use Sculptex or Chavant NSP - both good Non Sulfur modeling clays.
@righteoushero You can use any non-porous material. Melamine board from a home improvement/hardware store works well.
We used a sulfur free clay called Sculptex available from Reynolds Advanced Materials. No de-airing is necessary with Mold Star 15.
I always wondered how to do this. Thank you!
@videogames451 You can also use melamine board - available from most home improvement stores in the shelving section. - Jason - Smooth-On Inc.
This has been a great help, thank you.
@BurpAtTheMoon Yes, Mold Star 15 can be used for very small models or plastic miniatures.
@kevinruiz11 The useful temperature for Mold Star is 450°F, so for metal casting only low-melt like tin or some tin alloys.
@thetwinkleturnip Adding more water will produce thinner Alja-Safe.
@thetwinkleturnip You could try using our Alja-Safe alginate as a pourable 'place holder'.
great video, thanks so much
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.
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.
@Ruthles12 our distributors page has connections all over the world. Visit smooth-on . com for more info
You will need to have pins or similar supports attached to the core which keep it centered in the mold.
This is non sulphur clay - Chavant NSP you can purchase from Reynolds Advanced Materials, our distributor in 6 locations. reynoldsam . com
You could use this for wax casting. The temperature resistance is around 450F.
Very Helpful, I just bought a Starter Kit from you guys!
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!
@copburner This material can withstand about 400F. The material will not melt at higher temperatures, but will be damaged.
wow, that was incredible tutorial video. thank you
@7oMmY18 You can, as long as a suitable release, such as our Ease Release 200 is used to separate the new silicone from the cured.
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.
Our Smooth-Cast 65D is popular for your application.
Applying Ease Release 200 when pouring the first half is optional.
Genious, thanks a lot
perfeito trabalho.
That is awesome! Thank you for sharing.
+Sandra Leishman thank you for watching!
@ForeverBabies11 You can cast our Dragon Skin silicone into this type of mold if a proper release agent is used (Ease Release 200)
@allyaster This is non sulphur clay - Chavant NSP
Great tutorial. Thank you
Generally, CNC machines use rigid media, unsuitable for some rigid casting applications.
Reynolds Advanced Materials is our full-line distributor in Orlando.
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.
@lepuppeteer This is non sulphur clay - Chavant NSP
Easiest 2 part mold ive watched. Great video.
Glad it helped
This is the best step by step i found 👍
Very nice demo! Ty 💕👍🏼
Thank you for watching!
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.
Hi Smooth-On. I hope it's okay to ask a few questions here. I've been looking at your Mold Star 30 and was wondering if you can use the mold (once cured) with polymer clay? It says you can't before the silicone's cured, but didn't say anything regarding the mold after curing. Thanks in advance.
Once cured, the mold is fine for use with polymer clay.
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!
hi what are the pouring material is it PolyUrethane ?
what about the mechanical properties of Eurethane compared to ABS , need help !
god bless thanks !
Wow 😮 This is very helpful! Thank you!

Hello could you tell me please, on how many castings from plastic lack silicone forms from mold star 16 fast?
Awesome! Thanks!
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.
P.S. Your videos are amazing.
Good!
Thank you ^-^
Thanks mate.
Thanks for outstanding knowledge
Thank you! You just solved another problem for me! I am trying to work smarter not harder!
Thanks for watching! 😃
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!
Sorry no one replied to this comment sooner. Please feel free to contact our tech support line toll-free at 800-762-0744 to troubleshoot this. Platinum-cure silicones such as Mold Star and SORTA-Clear exhibit nearly no shrinkage and have exceptionally long library lives.
Amazing tutorial. Thank you!!!

I have a question about the Mold Star 15 slow, do I need to use a presure chamber to avoid air bubbles?
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!
@SmoothOnInc intersting idea! Thanks. Can this product be thinned to lower viscosity?
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?
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?
@SmoothOnInc Thank you, i have one more set of questions,
The level of importance on what is needed is:
Transparent
@SmoothOnInc Thank you.
Exactly what I needed thanks
Buen día necesito adquirir el producto! Gracias!
Grat video .Thank you very much
Would I be able to use the same process if I wanted to make a mold of sunglasses (since it is a rather skinny object)? If not, what process would work? Also, would the mold work for casting in wax (i.e., if I pour hot wax into the mold will it remain stable as a mold and allow the wax to turn solid)? Thank you.
The max temperature resistance of this silicone is 450F Our Mold Max 60 can withstand up to 560F
