Aluminium Mould Frame, 15mm Thick, Single Cavity Vulcanizer Rubber Casting, 4-3/8" x 5-5/8"

A wider aluminium mould frame designed for vulcanising larger jewellery pieces, ensuring a complete rubber cast for bangles and substantial pendants.

What it does

This substantial 15mm thick aluminium frame precisely holds your wax or resin model for vulcanisation. Its generous 4-3/8" x 5-5/8" internal dimensions accommodate designs that simply won't fit standard square frames, preventing under-filled or distorted moulds. The machined aluminium ensures even heat transfer from your vulcaniser, promoting uniform rubber curing. Its flat, parallel faces guarantee consistent mould thickness and accurate alignment during the pressing process.

How to use it

• Prepare your model within the frame.
• Place in vulcaniser and cure rubber.
• Carefully remove cured rubber mould.

Who it's for

Ideal for UK bench jewellers and casting houses needing to create vulcanised rubber moulds for wider pieces. This frame is a practical upgrade for silversmiths and designers working with larger pendants, statement rings, or bangles, replacing the need to compromise on model size or purchase custom solutions.
