12" Plain Round Mould

The 12" Plain Round Mould from Shrebhavi is a large-format flexible silicone mould built for serious resin casting. At 12 inches (approximately 30 cm) in diameter with a 20mm pour depth, it gives you the surface area you need for statement-sized projects — without having to piece together smaller casts or compromise on scale.

The interior surface is completely smooth and plain, so your finished piece reflects exactly what you put in — vibrant alcohol inks, layered pigments, dried flowers, or metallic powders — with a clean, mirror-like face once demoulded. Works reliably with standard two-part epoxy resin and UV resin. Suitable for hobbyists and small resin businesses producing wall clocks, decorative trays, art panels, and centrepiece platters.

• Large 12" diameter, 20mm depth — enough volume for single-pour wall clocks, serving trays, and resin art panels
• Smooth plain interior — delivers a glossy, texture-free surface on cured resin with no pattern interference
• Flexible food-grade silicone — peels away cleanly after curing; no release spray needed for most epoxy resins
• Compatible with epoxy and UV resin — handles standard casting resins available in India without warping or staining
• Reusable and durable — retains its shape across multiple pours when stored flat and kept away from sharp tools
• Ideal for Indian craft businesses — consistent round shape suits clock inserts, coaster sets, and made-to-order resin decor
• Easy to clean — once fully cured resin is removed, wipe with a dry cloth; avoid abrasive scrubbers to extend mould life

How to Use

Place the mould on a flat, level surface before pouring — any tilt will show in the finished piece at this diameter. Mix your epoxy resin per the manufacturer's ratio, pour slowly to reduce bubbles, and use a heat gun or torch lightly over the surface to pop any air pockets. Allow full cure time (typically 24–48 hours for epoxy) before demoulding. For UV resin, cure in sections using a UV lamp rated at 36W or above.

Safety Tips

Always wear nitrile gloves and work in a well-ventilated area when handling uncured epoxy or UV resin. Keep uncured resin away from children and pets. Do not use this mould in an oven or microwave — silicone is heat-resistant but resin fumes require open-air or ventilated workspaces only.
