Abstract (en)
[origin: EP1236525A2] Casting mold for metals has a mold cavity (10) formed by a conductive mold sections (2a, 2b). The surface of the cavity has a coating which is resistant to the effects of molten metal. This is less than 5 mm thick and is made from thermally-insulating, heat-shock-resistant material with a thermal conductivity below 1 W/mK. An Independent claim is included for a method for making the mold comprising: (a) applying a sol to the cavity surface, condensing to form a gel and drying to form the coating; or (b) gluing a sheet to the surface to form the coating.
