First, I want to show you some of the more general sets of silicone molds for resin. These are more basic shapes where you can focus on more perfecting the ratios of resin, playing with dyes, and maybe adding in some other decorative items. This includes a nice set of letters for creating keychains.
1) Repinsta Silicone Resin Molds
The first set I want to highlight here is pretty simplistic, and perhaps too much so for some users. There are 5 silicone molds with basic shapes, including a sphere, cube, and pyramid.

The company says it has upgraded the molds for ease of use, so negative reviews may be related to older stock.

Finally, this is another where it isn’t really a basic starter set, but the molds are simple shapes. I like the concept of these pots because you not only get the molds, but also a pair of wooden bases with lights on them. This turns the finished piece into a faux candle holder with some fun lighting effects. There are some issues get the piece out of the mold, but it is often worth the effort.

1) DIY Cup Resin Silicone Mold
First up, we have a silicone mold in the shape of a cup. The listing calls this a make-up brush or pen holder – seemingly targeting this towards teen girls. But, it could be for any small item or paintbrushes. The shape looks like cut crystal which allows for some fun effects with the resin.

My Top Pick Out Of the Best Silicone Molds for Resin
There is so much variety out there that it is very difficult to recommend one single product. Personally, I am drawn to the more decorative and practical items. I think that the domino and chess set kits are brilliant for that blend of creativity and functionality. There is a great sense of pride in building something you can use in fun family games. The molds also allow for some creative expression. I also think that the Halloween mold set has a similar vibe for family fun and design ideas.
However, if you are just starting out with silicone molds for resin and want a more simple approach, it may be better to go with something less complex. The Alphabet key chain set is a great choice because they are customizable and great little gifts. The kid’s Christmas set isn’t far behind for a festive project.
Why is Silicone Such a Good Material for Resin Casting?
Silicone is a wonderful material for casting of any kind because it is so durable, hygienic, and easy to turn out. A rigid plastic mold is too much like hard work – it is like using a silicone ice cube tray instead of an old-fashioned plastic one. Silicone saves so much time and effort that you can get better results and kids aren’t going to get frustrated.
Can You Use Soap and Candle Molds for Resin Casting?
Potentially. It all depends on the thickness of the silicone and the shape of the mold. Some may not lend themselves to casting in resin but are great for wax, soap, or fondant. However, it’s also not recommended to use resin in a mold and then use the mold for casting any food items due to the potential risk of transfer.
Should You Grease the Mold Before Adding Resin?
There are some people that say that you should do so to create a protective barrier between the resin and silicone. It might help the piece come out. But, you are also adding something that might affect the set or color of the resin. The best silicone molds for resin shouldn’t require this extra help.
What to Look Out for When Choosing the Best Silicone Molds for Resin
1) The theme. Do you want a basic set of shapes or letters to play with or something with a more specific end goal? Some of the best resin silicone molds have a practical side such as games pieces, bottle openers, and light holders.
2) The number of molds in the set. Are there enough pieces there to create a set of items or enough variation in styles? Some products have one design for repeated use. Others offer variations to suit different tastes.
3) Decorative elements. Some sets will come with additional features like glitter or sequins to add to the resin. You can stir these into a formula or sprinkle them into the mold for a fun effect.
4) Tools. There are also plenty of sets that come with sticks, droppers, and other elements to create a better result in the mold. Additional tools may also mean keychain rings and other practical elements for functional objects
5) The ease of use. Check user reviews to see how easy it is to get the piece out of the mold and if the molds are durable enough for repeated use. Some of these kits are great for kids because of the basic shape and thinker molds. Others are more intricate and need some thought regarding the placement of color.
6) The quality of the finished piece. How easy it is to get a perfect shape and an item that works as advertised? Are they prone to bubbles and rough edges?
Finding the Best Silicone Resin Molds for Your Needs
In the end, the final choice has to come down to your skillset, confidence levels, and how much you want from a kit. There are products here that are perfect starting points before moving onto a themed or novelty item. Even then, some of those pieces are more adult and require a steady hand and forward planning. Make sure to get a good idea of what the sets expect from you as an artist and that they are going to be enjoyable to use. Once you get the hang of them, you can work your way up to bigger and better things.
I’m a stay at home mom with our two kids. I really enjoy doing crafts with my kids however, that is typically a challenge with how limited their attention span can be and how messy it gets. So, I’m always looking for ways to make crafting an enjoyable experience and creating fond memory for all of us.
