Abstract

1,111,436. Moulding plastic materials CIBA Ltd. 25 Nov., 1965 [26 Nov., 1964], No. 50208/65. Heading B5A. A method of moulding articles, e.g. electrical insulators, bushings or housings for electrical fittings, from a resin mixture having a hardener and a particulate filler in which most of the particles have a grain size less than 160Á includes the steps of compressing the mixture in a mould, and when the compressed body has hardened sufficiently it is impregnated with a liquid mixture of synthetic resin and then cured. Before hardening and impregnation the body may be removed from the mould. The proportion of filler in the compressed mixture may lie between 65 and 98%, and may comprise aluminium oxide trihydrate, calcite, quartz flour or mica powder or mixtures thereof. Examples of resins used in the compressed mixture include vinyl chloride, polyesters and epoxy resins, and a similar or different resin may comprise the impregnant. A composite article may be formed by moulding and hardening the individual parts separately, and then assembling them and then impregnating and curing the assembly. Terminals, electrodes and capacitor coatings may be embedded in the moulded article. A bushing having capacitor coatings, Fig. 8, not shown, is formed by moulding interfitting concentric tubes (7, 8, 9) separately, the tubes having cylindrical capacitor coatings (11, 12), assembling the tubes one within the other, inserting a conductor (10) in the innermost tube, and impregnating and curing the assembly. The impregnation is effected in a container (13), Fig. 10, not shown, to which the impregnant is supplied through a passage (14), a cover (15) closing the container and being connected to a vacuum source. A hollow body may be moulded by the described method, into which fittings such as electrodes and coils are housed, the hollow spaces then being filled with a resin compound.
