  • This mold making tutorial video shows how to make a two piece silicone block mold using Mold Star 15. The finished mold can be used for casting resin, wax, foam, and many other materials.
    The original model is a plastic sphere. The 2-part mold should be split along the horizontal axis.

    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.

    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.

    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).

    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.

    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).

    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.

    @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.

    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.

    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?

    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

    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.
