Abstract (en)
[origin: WO9310686A1] In order to produce pieces of jewellery with one or several set stones, a master pattern with settings for the stones is produced, a master mould is produced by moulding from the master pattern, a model is produced in the master mould with a castable or injection mouldable modelling mass that can be ejected by heating from the master mould, the stones are inserted into the model and set by deformation of the setting, a casting mould is produced by embedding the model in a fire-resistant moulding mass and by ejecting the modelling mass from the casting mould, metal is cast into the casting mould by a spin casting or vacuum moulding process and the piece of jewellery is removed from the mould once the metal has cooled down.
