Best Moulds for Insect Embedding in Resin

← Back to How to put insects under resin?

Selecting the right mould is a crucial first step when preserving insects in resin, ensuring both ease of release and professional-looking results for your project.

Why Silicone Moulds Are the Top Choice

For embedding insects in resin, silicone moulds stand out as the preferred option. Their flexible nature allows the cured resin piece to be removed effortlessly, helping prevent damage to delicate insects inside. Silicone is forgiving and doesn’t require aggressive mould release agents, making it especially suitable for beginners as well as advanced crafters. You’ll find silicone moulds in a variety of shapes and sizes, from simple blocks to detailed designs, so you can match your mould to the scale and style of your project.

Practical Tips for Mould Selection and Use

Choose a mould size appropriate for the insect and the depth of resin you intend to pour; avoid moulds that are much larger than needed, as deep pours can be prone to overheating.
Opt for high-quality, smooth silicone moulds to ensure a clear, bubble-free finish on your final piece.
If you are embedding small specimens, moulds for jewellery or cabochons are ideal and can be found in various geometric or organic shapes.
Always check the maximum recommended layer thickness for your chosen resin; for example, the “Trasparente” Multipurpose Clear Epoxy Resin is suitable for castings up to 2cm thick, pairing well with medium-depth silicone moulds.

When Mould Choice Really Matters

If you plan to cast unusual shapes or want to produce several identical resin pieces, using flexible and reusable silicone moulds is particularly valuable. The right mould ensures the details of the insect and the clarity of the resin are preserved, allowing your unique keepsake or specimen to truly stand out.
