Aluminum Mould Frame, 20mm Thick, Single Cavity Vulcanizer for Rubber Casting, 4" x 4-7/8" Size

Achieve deeper rubber mould impressions for complex wax masters with this 20mm thick single-cavity aluminium vulcanizer frame.

What it does

This robust aluminium frame precisely holds your rubber during the vulcanising process, ensuring a complete and accurate impression of taller or more intricate wax models. Its substantial 20mm thickness prevents premature rubber compression, allowing for full detail capture. The frame is milled from a solid block for even heat distribution, and features radiused internal corners to minimise stress on the rubber, promoting mould longevity and consistent results.

How to use it

• Place your wax model and cut rubber into the frame.
• Secure in your vulcanising press and apply heat and pressure.
• Allow to cool before demoulding your rubber impression.

Who it's for

This frame is an essential upgrade for UK bench jewellers and casting technicians producing their own rubber moulds. It replaces standard thinner frames when working with detailed pendants, substantial ring settings, or any multi-layered wax master, ensuring superior mould definition and reducing the need for complex repairs or remakes.
