The Vehipa 14-inch round silicone mold is designed for large epoxy pours, including river tables, deli trays, and wall decor. It features a soft, flexible silicone with a smooth surface, reinforced bottom, and improved thickness to resist deformation after curing. This mold supports easy release when the resin cures, reducing final smoothing work and enabling repeated use.
- Size: 14 inches wide, 2 inches high
- Material: Flexible silicone, durable and tear-resistant
- Release: Easy pop-out with minimal distortion
Applications include large tabletop panels, decorative plaques, and statement pieces for living spaces. When using this mold, ensure proper ventilation during mixing and cure, and consider using a release spray or a light soapy rinse for easier demolding.

Buying Guide: Large Silicone Molds for Epoxy Resin
Key purchase considerations help you choose the right mold for your projects. Consider size and shape relative to your planned piece, ease of demolding, and the mold’s material quality. Teardowns below compare common options and practical buying tips.
- Size and volume: Large molds enable big projects like tables and trays. Ensure your work surface and curing setup can accommodate the footprint and height.
- Material quality: Look for thick, tear-resistant silicone with a smooth interior. High-quality silicone reduces edge flaws and promotes clean releases.
- Release and demolding: Molds with reinforced bottoms and thicker walls resist deformation, allowing easier release and longer mold life.
- Surface finish: A mirror-like interior yields minimal post-processing. Avoid molds with rough interiors that require heavy sanding.
- Versatility: Some sets include multiple sizes or shapes, expanding the range of projects from trays to decorative panels and coasters.
- Care and maintenance: Clean with mild soap and water. Avoid abrasive cleaners that could scratch the interior; use mold release spray if needed for very complex shapes.
- Materials compatibility: Confirm resin type compatibility (epoxy, acrylic, or other casting resins) and avoid materials that could react adversely with silicone.
Practical considerations include oven-safe or heat-tolerance limits for resin curing in low-vent environments, and ensuring you have enough working space to manage large pours without spilling. For display pieces, select shapes that complement home interiors or functional items like trays and cutting boards. A mix of large volume molds and smaller accent molds provides a versatile epoxy toolkit for a range of projects.
