Abstract

1393534 Compression moulding GKN SANKEY Ltd 26 June 1972 [7 July 1971] 31782/71 Heading B5A In a method of moulding an article of thermosetting material which has low shrinkage on cooling, a charge 44 of the material is placed between mould parts 15, 16 which are then brought together and locked by U-shaped clamps 27 and wedges 35; pressure on the material is then applied by pistons 25 before substantial polymerization takes place, to force it into engagement with the mould cavity surfaces. The moulded article is removed from the lower mould part by the raising of the pistons, each of which is operated by a jack.
