Abstract

952,788. Moulding processes. FOSECO INTERNATIONAL Ltd. Jan. 31, 1963 [Feb. 15, 1962], No. 5746/62. Heading B3F. Foundry moulds and cores and like shaped bodies are bound with aqueous alkali metal silicate and hardened by subjecting to a high vacuum. The mixture may be an exothermic composition and include sugar, pitch and other carbon compounds. A mould dressing may be applied to the pattern so that it is stripped with the mould and dried by the vacuum treatment. If a spirit based dressing is applied after formation of the mould &c. it may be burnt off to give a hard surface. Specification 627,678 is referred to.
