Neill's Materials Mould Keys, 10 pieces
Mould Keys are small polyurethane resin shapes that let you form registration keys in a multi-part mould. You press them into the dividing wall, cast your mould, and from then on the two halves always drop back into exactly the same position.
Why choose Mould Keys?
Without registration keys the halves of a mould slide over one another and your cast comes out misaligned. Most people carve dimples into the clay wall by hand, or press a coin into it. That works, but it takes time and it is rarely the same twice.
These keys press a clean, crisp shape in one movement. They self release from most mould making materials, so you do not need a release agent. And you use them again and again.
How do you use Mould Keys?
Build your dividing wall in clay and press the keys halfway into it at regular intervals, so that part of each key stands proud. Cast the first half of your mould. Once it has cured, remove the clay wall and the keys, then cast the second half against the first. The impressions the keys left behind now form the sockets that the matching shapes on the other half drop into.
The keys adapt to your work. You can saw and sand them, and bend and shape them with heat, for instance when you want to run them around a curve.
What do you use them for?
- Forming registration keys in a two-part or multi-part mould
- Moulds for silicone prosthetics and face pieces
- Moulds for props and sculpture
- Work where the mould is opened and closed repeatedly
- Finishing a clay dividing wall neatly and repeatably
