10 Best Moulds For Resin Casting

The LET'S RESIN Epoxy Resin Kit is a strong choice for beginners interested in resin casting, especially those wanting to experiment with different shapes. It comes with five silicone moulds (sphere, cube, pyramid, square, and round), all made from durable, flexible silicone that’s easy to release your resin pieces from without damage. The moulds hold their shape well and have enough detail to create clean, polished pieces.

The included 500ml crystal-clear epoxy resin is self-leveling and mixes well with color pigments or glitters, which are also part of the kit along with dried flowers, making it easy to customize your projects. This kit also covers your basic tools and safety needs like gloves and measuring cups, which is great for beginners who want a ready-to-go set. While the silicone moulds are durable and versatile—usable with other materials like soap or wax—the product doesn’t specifically highlight heat or chemical resistance beyond typical silicone qualities, so it might not be best for projects involving high heat or harsh chemicals. Also, the size range of the moulds is standard, which suits small to medium resin crafts but not larger projects.

This kit is user-friendly, well-rounded for beginners, and ideal if you want to start crafting resin art with a variety of shapes and decorative options right away.

The LET'S RESIN Extra Deep Coaster Silicone Mould is a versatile option for resin crafters, especially those making coasters or small decorative items. Made from flexible, high-quality silicone, it’s durable and easy to clean, which helps with multiple uses. The 0.8-inch depth is deeper than many coaster molds, allowing you to embed larger objects like flowers or wood pieces, providing creative freedom.

Its round shape is classic and works well for various resin projects beyond just coasters, like paperweights or keepsakes. The glossy interior surface helps you achieve smooth, shiny finishes without extra polishing, and the mold release is straightforward using either spray or soapy water, which makes removing cured resin less frustrating. At 4 inches in diameter per cavity and a total of six cavities, it offers a good balance between size and quantity for hobbyists.

It is designed mainly for casting resins like epoxy and not suitable for coating resins, so users should check compatibility with their materials. While it’s fairly durable, like most silicone molds it needs gentle handling to avoid deformation over time. This mold set suits beginners and intermediate resin crafters who want to experiment with larger and more detailed coaster designs or small art pieces.

The LET'S RESIN Chess Molds set is designed especially for resin casting enthusiasts who want to create a full 3D chess set with ease. Made from resin silicone, these molds are flexible and durable enough for repeated use and allow detailed, full-size chess pieces and board to be made in just a couple of pours. The rectangular board mold and separate molds for all chess pieces, including pawns and major figures, mean you get a complete 32-piece set with good size and shape accuracy. The smooth, glossy interior helps in easily releasing resin pieces when combined with a mold release spray or mild soapy water, reducing the risk of damaging delicate details.

The set also includes mica powders for adding color and a storage bag for keeping finished pieces safe, which is a nice practical touch. While the silicone molds provide good durability and detail, extreme heat or harsh chemicals could still damage them over time, so careful handling is recommended.

This kit is ideal for hobbyists who enjoy creative resin projects and want to make personalized, decorative chess sets. It’s family-friendly and offers a fun way to spend time crafting unique game pieces, making it less suitable for industrial or heavy-duty use but perfect for DIY resin art at home.
