Can I Use Any Mould for Tray Making?

What Makes a Good Tray Mould?

High-quality silicone moulds are generally preferred for resin tray projects thanks to their flexibility, smooth finish, and ease of demoulding. However, not every silicone mould will deliver optimal results. Pay close attention to the mould’s shape and dimensions to ensure it matches your intended tray style—whether rectangular, circular, or a more creative form like a triangle.

• Heat resistance: The mould must tolerate the heat produced during resin curing. Many artistic and craft silicone moulds are designed to withstand temperatures between -40°C and +210°C, providing adequate protection during standard epoxy processes.
• Durability: Opt for a mould that can be reused without warping, as this ensures consistent, professional-looking trays across multiple uses.

Tips for Choosing and Using Silicone Moulds

Select a mould suited specifically for resin work. For example, a tray mould like the “Tray” – Complete Resin Tray Kit includes a purpose-made silicone mould, designed to pair with the physical and chemical demands of epoxy resin pours. Check the thickness and smoothness of the mould’s interior to achieve a refined finish. Cleaning and storing your mould properly extends its life and preserves the clarity of subsequent pours.

When This Matters Most

Proper mould selection is crucial if your design has unique details or requires a high-gloss finish. Using a mould not intended for resin or one lacking heat resistance could lead to warping or poor demoulding, spoiling your project.
