Compact Square Silicone Casting Mould

This compact square silicone mould features a neat selection of square cavities in mixed sizes, perfect for casting small resin blocks, tiles, jewellery bases or test pieces. It’s especially useful when you want to pour several colours or designs at once without committing to large volumes of resin.

The flexible silicone releases casts cleanly while keeping sharp edges and flat faces, making it ideal for layered pours, pigment experiments, embeds and decorative inserts. The smaller overall footprint also makes it easy to work with on crowded benches or when space is tight.

  • Multiple square cavities in assorted sizes
  • Compact tray design for efficient batch casting
  • Flexible silicone for easy demoulding
  • Suitable for epoxy resin, UV resin, Jesmonite and plaster
  • Great for tiles, blocks, jewellery bases and colour testing

Approx dimensions:
Overall mould size: 150mm × 125mm
Mould thickness: 9mm
Square cavities range from approximately 12mm up to 54mm

Allow resin to fully cure before removing casts. Wash with warm soapy water after use and store flat to help preserve the mould shape over time.
