Abstract
The invention relates to fixing a metal strength member on a non-metal part. A heat-resistant fibre glass layer is inserted between the strength member and the non-metal part, the layer extending throughout at least the zone of the non-metal part which corresponds to the point where the molten metal which forms the strength member is injected and being coated with a non-adhering inert inorganic substance so that the layer is thus compressed between the non-metal and the metal part when the metal part is applied against the non-metal part. Application in particular to manufacturing tempered glass electric insulators with moulded aluminium caps.
