Aluminum Mould Frame, 1-3/8"" Thick, Single Cavity Vulcanizer Rubber Casting, 3-3/8"" x 4-3/8"" Size

This robust aluminium mould frame is designed for vulcanizing single-cavity rubber moulds for small jewellery pieces on the bench.

What it does

This mould frame is precisely milled from a solid block of aluminium, ensuring excellent heat transfer for consistent vulcanization cycles. Its compact outer dimensions minimise rubber usage, directly reducing material costs for each mould produced. The frame's perfectly flat, parallel faces guarantee even pressure distribution within your vulcanizer, crucial for capturing fine detail in your wax models. The single, central cavity with gently rounded internal corners is ideal for small rings, pendants, or charms.

How to use it

• Prepare your wax model and flask.
• Assemble the rubber mould and frame.
• Place in vulcanizer and cure as per rubber instructions.

Who it's for

This frame is a practical choice for UK bench jewellers, casting houses, and jewellery design studios focusing on smaller items. It's a cost-effective upgrade for those frequently producing single-cavity moulds, replacing less efficient methods for small-scale production and pairing well with standard vulcanizing presses.
