For jewellers vulcanizing taller or more complex wax models, this 20mm thick aluminium mould frame provides the necessary depth for a complete impression. Its solid construction ensures the rubber fully envelops the master, preventing the surface exposure common with standard 15mm frames.

Key features

  • Extra 20mm thickness accommodates deeper models than standard 15mm frames.
  • Milled from a solid block of aluminium for consistent heat transfer during vulcanization.
  • Features a single, central cavity with radiused internal corners to reduce stress points.
  • Flat, parallel faces ensure even pressure distribution within the vulcanizing press.
  • UK-stocked for immediate, same-day dispatch to your workshop.

Who it's for

An essential tool for UK bench jewellers, casting houses, and jewellery design studios that produce their own rubber moulds in-house. It is particularly suited for those working with taller ring settings, detailed pendants, or other complex three-dimensional masters.
