Abstract

1,223,653. Split moulds of variable hardness. OPTIPATENT A.G. 4 Feb., 1969, No: 5949/69. Heading B5A. A split mould for the casting or injection moulding of synthetic resin articles is made from a cross linked polymer, the degree of cross linking being controlled so that the mould is rigid at room temperature and has a low ball indentation hardness at elevated temperatures so that it can undergo plastic or elastic deformation on the surface. The mould material is preferably an epoxy resin, polyurethane resin or saturated polyester and the mould may have a surface layer 0À1 to 0À3 mm. thick of a hard, wear and temperature resistant material. The mould material may be reinforced, with for example glass fibre mats, rovings or fabrics. Compositions for producing moulds for the production of spectacle frames and combs are described.
