Natches are strong plastic interlocking pegs for accurate location and aligning of plaster piece-moulds.
First, the rounded ends are pushed into the clay model then one side of the mould is cast in plaster. When the plaster is set the clay is removed and a second natch is pushed onto the exposed end of the first one. This natch is then embedded into the second plaster cast and when separated leaves a plug and socket on the joint. The 2 sections of plaster mould can be located exactly together by the natches.
They are wear-resistant and are fully reusable.
Can also be used with silicone, GRP and polyurethane moulds.
Sold in Pairs.
