A mould for forming an anatomical replica, such as of a skull, comprises moulding each of a plurality of mould parts on an anatomical original e.g. a skull mandible. Each mould part is built up from successively applied layers 3 and 4 of silicone rubber and strips of strengthening material to form, after curing a flexible inner skin 7, onto which is then applied successive layers of resin, woven tissue glass and chopped glass strands, to form a rigid outer casing 6 which is detachable from the skin 7, to enable release of a subsequently moulded replica from the mould part, by peeling away of the flexible inner skin 7. The replica is moulded by applying resin and glass fibre reinforced resin coatings 12, 13 to the inner skin surfaces of opposed mould parts 6, 7 and 6', 7' and curing the skins together between the clamped mould parts, to form a hollow walled replica. The mould parts may include separately cast rubber inserts 8. <IMAGE> |
