Resin casting moulds: where to start?

Silicone moulds

You can find a huge variety of silicone moulds on Etsy, Ebay and Amazon as well as in specialist resin shops. These are flexible and have some stretch to them, so they lend themselves to detailed designs as well as simpler ones. Because they can be stretched, they can be used for three dimensional shapes (you would be unable to extract a 3D shape from a rigid mould). It is possible to tear silicone moulds so be gentle when extracting resin pieces!

Silicone moulds can be either shiny or matte within the mould, and this will determine the finish on the resin you cast. If you use a silicone mould with a matte interior, your final item will be matte and dull in appearance. If you use a mould with a shiny interior, it will produce shiny items, however over time, as it is used it will gradually lose the shine.

Silicone moulds have a limited lifespan and will eventually wear out. If the mould is shiny, over time it will become more matte in appearance, and will lose some of its definition on details. If there is a mould you really love, it can be worth buying an extra one to make sure you can keep working with it for longer!

When you are not using your silicone moulds, store them in a container to keep dust off them and help stop them becoming damaged. You'll find that the texture of a silicone mould is a bit of a magnet for dust and lint, which is hard to get off and can spoil projects.

If you need to wash them, be very gentle not to scratch the inside of the mould cavity and leave them to fully air dry. If they have any water on them when you use them, you’ll ruin your resin project.

Plastic polypropylene or polyethylene moulds

These are hard, rigid moulds and are made from plastic sheets. They tend to be less detailed than silicone moulds, but they are often cheaper.

Plastic moulds do not always produce shiny resin pieces – they may come out dull depending on the plastic. If this is the case, you can recoat the surface with another layer of resin to make it shiny.

As they are rigid, they are only suitable for relatively flat mould shapes (more three dimensional designs would be impossible to de-mould). These moulds are often used for small to medium sized cabochon shapes, where multiple shapes are part of the same mould.

More resin moulds to try

There are lots of moulds available to use with epoxy resin, but if you can't find exactly what you are looking for, you can also use some moulds designed for other things such as silicone baking moulds or polymer clay moulds. If you decide to use another type of mould for resin casting check what it is made out of before pouring resin into it - resin will adhere to some plastics and could ruin the mould making it unusable. If you use a mould designed for food, keep that just for resin use and don’t make food with it to avoid any chemical contamination.

How to make a silicone mould

If you still can’t find the mould you are looking for, you can make your own silicone mould using a kit such as this one from DecorRom (Amazon, £18.99).
