Abstract

808,364. Moulding processes. BAKELITE Ltd. Oct. 12, 1956 [Oct. 14, 1955], No. 29412/55. Class 83 (1). Shell moulds are made by blowing sandresin mix into a cavity between a hot patternplate and a contourplate through holes in the contour-plate, the hot pattern with the shell thereon being removed, and the shell cured while in position thereon. Each opening 16 in the contour plate 13 has a valved diaphragm 20 to stop mix falling through when the blowing pressure is released. The method is said to enable mixes of a resin content of 1¢-2 per cent to be used. Binders such as mineral oil, oleic acid, and vegetable oils such as rape oil and olive oil, may be added to the mix.
