Silicone moulds for coasters

Whether you’re new to resin coaster making or a professional artist creating signature pieces, choosing the right silicone mould is key to achieving beautiful results. At ResinPro, our curated range covers all major coaster shapes and set sizes, empowering you to bring any creative vision to life.

Each mould is crafted for specific uses — from professional finish coasters to detailed resin artwork, and even functional homewares. Factors such as your resin type, desired finish, and project scale influence which option is best. Here, we compare all options and help you find the moulds that match your technique, style, and requirements.

Making professional finish coasters

For those focused on professional finish coasters, options such as the “Four in One” – Silicone Coaster Mould, 21cm Diameter and the “Agate Geode” – Silicone Mould Set for Handcraft Coasters, 6pcs shine. These moulds feature exceptionally smooth interiors and are made from reusable, non-stick silicone, ensuring easy demoulding and a surface that rarely requires post-casting polishing.

Both options are ideal for those creating artistic coaster sets as gifts or for sale, thanks to their combination of size options, durability, and finish quality. To maximise heat resistance, a clear 3mm layer of heat-resistant resin is recommended, allowing the final product to withstand everyday use. This technique is especially useful when crafting practical coasters.

Decorative and creative coaster moulds

The “Maple Leaf” – Silicone Mould for Resin Casting, 9×8.5cm introduces a playful silhouette, perfect for decorative resin casting or as a unique base for jewellery. Its flexibility and high heat resistance accommodate versatile craft applications. Similarly, the “O” – Geode Coaster Silicone Mould – 13cm is suited for crafters who want sharp edges and classic geode aesthetics in their coasters.

Both moulds are designed to support intricate details while allowing for the use of different resin types, pigments, or even inclusions like dried flowers. With high-quality silicone construction, they offer multiple casting materials compatibility, easy cleaning, and resilience over repeated use.
