Vulcanising Mould Frame, Single Cavity — Aluminium, 4 × 4-7/8 Inch, 5/8 Inch Thick

Cutting your own vulcanised rubber moulds starts with a frame that holds its shape under heat and pressure. This single-cavity aluminium frame sits between the platens of a standard jewellery vulcaniser, containing the rubber whilst heat moves evenly through the block — the groundwork for reliable wax injection moulds for small and medium cast components.

The block is solid aluminium with machined flat faces, so clamping pressure spreads uniformly and mould thickness comes out consistent. The internal corners of the rectangular cavity are radiused to ease stress on the finished mould, and at 4" × 4-7/8" with a 5/8" depth it accommodates most standard jewellery models.

• Solid aluminium block construction for even heat distribution during vulcanization.
• Single rectangular cavity with radiused internal corners to reduce stress on the mould.
• Machined flat faces ensure consistent pressure and uniform mould thickness.
• External dimensions of 4" × 4-7/8" fit standard jewellery vulcanizer presses.
• A 5/8" thickness provides adequate depth for most standard jewellery models.

Who it's for

Primarily for bench jewellers and casting houses in the UK who manage their own rubber mould production for lost-wax casting. Also suitable for model makers and designers creating small-run components who require repeatable wax injections from a durable mould.
