Method of moulding by casting by means of a filled polyester resin. The invention relates to a technique which employs a filled polyester resin, irrespective of the volume or the shape of the component to be obtained by moulding. The principle resides in the metering of the accelerators and catalysts and, above all, in the addition to this mixture of a filler (glass frit, sand, silica, etc) intended to moderate and to control the polymerisation reaction of the filled polyester resin. The method according to the invention is particularly intended for the manufacture of light fittings or of any other article which may or may not be related to lighting, irrespective of its shape or its volume.
